National Gypsum Companyfeatures a wide variety ofgypsum board productsand accessories includingregular gypsum board, Fire-Shield fire resistant board,1/4" High Flex GypsumBoard, 1/2" High StrengthCeiling Gypsum Board, Hi-Impact Gypsum Board,Gridstone Ceiling Boards,Gypsum Sheathing, Fire-Shield Shaftliner, DurasanPrefinished Gypsum Board,Exterior Soffit Board, andJoint Treatment products.

Our concentration isn’t onbuilding products alone,however. At the NationalGypsum Research andTesting Center, we developcomplete construction sys-tems. In such systems,products are evaluatedtogether as complete build-ing assemblies–walls, parti-tions, floors and ceilings.

We have included in this sec-tion details and applicationinstructions for many ofthose assemblies: SteelFrame Partitions, SteelFrame Ceilings/FurringChannels or Studs, Wood

Frame Wall and Ceilings,Gypsum Board Over FoamInsulated Masonry andSolid Laminated Partitions.

Before a National GypsumSystem is released to thebuilding industry, it is thor-oughly tested, and results arecorrelated and charted tomake it easier for the builderor specifier to match a sys-tem to their needs or to thebuilding codes.

The drywall construction sys-tems referred to in this cata-log are designed primarilywith materials manufac-tured by National Gypsum

Company. Substitution ofany product or otherbrands in a tested system is not recommended.

Field installation of tested sys-tems must be identical tolaboratory installation toproduce optimum perfor-mance of these systems.Performance tests are con-ducted in accordance withaccepted national stan-dards under controlled lab-oratory conditions to mini-mize variances and to per-mit comparison of testresults with all types of sys-tems, similar and dissimilar.

METRIC CAPABILITIESThe Federal Government has

mandated that each federalagency make a transition tothe use of metric units inall federal procurement,grants and business-relatedactivities. NationalGypsum Company, incomplying with this order,provides a full line of gyp-sum board products in“hard” metric dimensionswith regard to width andlength. Standard boardofferings are made in thewidth of 1200 mm and alength of 3600 mm. Jobsize lengths are availableon a special order basisrequiring minimum ordersand extended lead times.Contact your localNational GypsumCompany representative forfurther information.Thickness of gypsum boardwill be “soft” converted tothe metric equivalent.

ENVIRONMENTALCONDITIONSMaintain a room temperature

of not less than 40˚F (4˚C)during application of gyp-sum board except whenadhesive is used for theattachment of gypsumboard. For the bonding ofadhesive, joint treatment,texturing, and decoration,the room temperature shallbe maintained at least at50˚F (10˚C) for 48 hoursprior to application andcontinuously thereafteruntil completely dry.

Note 1: Precaution–When atemporary heat source isused, the temperature shallnot exceed 95˚F (35˚C) inany given room or area.

Note 2: Precaution–Maintainadequate ventilation in theworking area during instal-lation and curing period.

Protect gypsum board productsfrom direct exposure to rain,snow, sunlight, or otherexcessive weather condi-tions.

GUIDELINES FORPREVENTION OF MOLDGROWTH ON GYPSUMBOARDGypsum board does not gen-

erate or support thegrowth of mold when it isproperly transported,stored, handled, installed,and maintained. However,mold spores are presenteverywhere and whenconditions are favorable,mold can grow on practi-cally any surface.Observing these guide-lines will help minimizethe potential for moldgrowth on gypsum board.Gypsum board must bekept dry to prevent thegrowth of mold.

Transportation and ReceivingGypsum board must be pro-

tected during transit with aweather-tight cover ingood condition.

Plastic shipping bags areintended to provided pro-tection during transit onlyand must be promptlyremoved upon arrival ofthe load. Failure toremove the shipping bagcan increase the likeli-hood of developing condi-tions favorable to thegrowth of mold.

Storage and HandlingGypsum board must be

stored in an area that pro-tects it from adverseweather conditions, con-densation, and other formsof moisture.

Job site conditions that canexpose gypsum board towater or moisture must beavoided.

Gypsum board must bedelivered to the job site asnear to the time it will beused as possible.

ApplicationProvisions must be made to

keep gypsum board drythroughout application.

Gypsum board that has visi-ble mold growth must notbe used.

Gypsum board on walls mustbe applied with a mini-mum 1/4" (6.35 mm) gapbetween the gypsumboard and the floor.

Gypsum board must not beapplied over buildingmaterials where condi-tions exist that are favor-able to mold growth.

Maintenance FollowingApplication

Essential elements of soundweather tight buildingenvelope must be properlymaintained, such as theroof, sealants, windows,etc.

Immediate and appropriateremediation measuresmust be taken as soon aswater leaks or condensa-tion sources are identified.

Routine cleaning and mainte-nance operations must beperformed so as to preventsaturation of the gypsumboard.

DESCRIPTION

Gold Bond® BRAND GypsumBoard comes standard withGridMarX™ guide marks,printed on the paper sur-face. These guide marksalign with standard build-ing dimensions and help toquickly identify fastenerlines for stud and joistframing. Using GridMarX,accurate cuts can be madewithout having to drawlines. GridMarX also assistwith quick identification ofnail/screw pattern.

GridMarX guide marks run themachine direction of theboard at five points in 4"increments. Marks runalong the edge in bothtapers and at 16", 24" and32" in the field of theboard. The marks cover

easily with no bleed-through using standardpaint products.

Vertical Application - In a ver-tical application, GridMarXserve as a guide mark tohelp identify the exactlocation of framing mem-bers behind the gypsumboard, eliminating theneed for field applied vertical lines.

Horizontal Application - In ahorizontal application,GridMarX serve as a reference mark to helpidentify the location offraming members behindthe gypsum board. (If fram-ing member is located 2" tothe right of the GridMarXat the top edge of theboard, it will be located 2"to the right down the faceof the board.)

Fire and sound ratings forbuilding systems utilizinggypsum board are dependenton the core type andthickness of the gypsumboard, its application inconjunction with thecomponent parts, and themanner in which it isapplied.

Tests for fire resistance andsound transmission,performed by independentlaboratories, have resulted inspecific ratings for walls/partitions; floor/ceilingassemblies; shaftwalls,stairwells and areaseparation walls; andcolumns. For maximum fireresistance and sound control,double layer construction isgenerally recommendedsince the additional massfurther retards heat and noisepenetration.

Gypsum board can be installedto both metal and woodframing using nails, screwsor adhesives in combinationwith nails or screws. In manyinstances, the applicationwill dictate which fasteningmethod is appropriate.

Control joints may be necessaryto prevent cracking in thegypsum board facing ofdrywall systems, especiallyin areas where structuralelements such as slabs,columns or exterior wallscan bear directly on non-load-bearing partitions. Torelieve the stresses whichoccur as a result ofmovement induced bychanges in moisture,temperature or both, controljoints are required in bothpartitions and ceilings.

GYPSUM BOARDINSULATING PROPERTIESFor purposes of calculating

“U” values, the “C” factor for1" gypsum board is 1.2;Resistance “R” for 3/8" boardis .32; for 1/2" board .45; for5/8" board .56 and for 1"board .83.

DESCRIPTION

Gold Bond® BRAND Gypsum Board

Gypsum Board is the name fora family of board productsconsisting of anoncombustible core,primarily of gypsum, with apaper surfacing on the face,back and long edges.*

The popularity of gypsum boardresults from a number offactors. First, it takes virtuallyany decoration – from paintor textures to vinyl andpaper laminates. It also lendsitself to creative shaping ofinterior surfaces, allowingthe maximum in designflexibility. Gypsum board isan economical alternative toother products. Because it islightweight, it is easy tohandle for speedyinstallation. With its naturalproperties, it is durable yeteasy to repair. In addition,gypsum board’s fireresistance and sound controlcapabilities furtherdemonstrate its desirabilityin building systems.

Ever conscious of theenvironmental challengeswe face in today’s world,National Gypsum producesits gypsum board with 100percent recycled paper onboth the face and back.

Gold Bond gypsum board isavailable with a variety ofedge configurations. For easyjoint finishing, the taperededge is preferred to providea monolithic surface. Wherejoints will be exposed,square or beveled edgesshould be considered.National Gypsum alsomanufactures gypsum boardwith proprietary edgeconfigurations made toaccommodate a variety ofwall systems and finishingtechniques.

CURVED SURFACESTo apply gypsum board over a curved surface, place a stop at one end

of the board and then gently and gradually push on the other end,forcing the center against the framing until the curve is complete.Shorter radii than shown in the table may be obtained by moisten-ing the face and back papers of the board with water, stacking on aflat surface, and allowing the water to soak into the core for at leastone hour. When the board is dry it will regain its original hardness.

Gold Bond® BRAND Fire-Shield®

Gypsum Board wasdeveloped to work incombination with otherproducts in an assembly toretard heat transfer throughthe assembly. Fire-Shieldgypsum boards are madewith cores formulated tooffer greater fire resistancethan regular gypsum board.Generically, these fireresistant boards that areused to delay heat transferto structural members aredesignated as “type X”products.

contains about 21 percentwater. When the board isheated, the water in thecore begins to evaporateand is released as steam,retarding heat transfer. Fire-Shield gypsum boardremains noncombustible.However, as shrinkageoccurs because of the lossof water volume, cracksoccur which permitpassage of fire and heat. To lessen this process, Fire-Shield gypsum boardis formulated by addingnoncombustible fibers to the gypsum to helpmaintain the integrity ofthe core as water volume is lost while providinggreater resistance to heattransfer.

For additional fire protection,Gold Bond Fire-Shield Cproducts are formulatedwith a mineral coreadditive which expandswhen subjected to heatwhich aids in holding thegypsum board together.

Fire-Shield gypsum boardsalso can be used ascolumn protection,delaying the rapid transferof heat to reduce thelikelihood that structuralmembers will lose strengthand fail to carry theintended load.

FIRE RESISTANCE RATINGSFire resistance ratings

represent the results of tests on assemblies made up of specific materials in aspecific configuration.

THE SECRET IS IN THE SHAPE OF THE JOINT AND THESTRENGTH OF THE COMPOUND

Standard tapered-beveled edge configuration.

Round edge configuration.

Easier Scheduling – Tapingwith Sta-Smooth Com -pounds and applying thefirst finishing coat, evenbefore the Sta-Smooth usedfor taping has dried, allowseasier job scheduling forthe drywall contractor andfinisher. This is particularlyadvantageous under slowdrying conditions.

The Sta-Smooth System produces a superior joint because theSta-Smooth Compounds are a hardening-type compound thatis not affected by humidity once it has hardened and dried. Italso maintains its hard core even with moisture added by theuse of the regular joint compounds for the finishing work. Sta-Smooth Compound firmly bonds the tape to the board and the board “V” edges to each other making a strong,rigidized joint.

Consult your local National Gypsum sales representative foredge configuration available in your market.

Gold Bond® BRAND Sta-Smooth® Gypsum Board

Sta-Smooth is a drywall system offering maximumjoint strength and easyapplication. It can be usedin any gypsum drywall system where conventionaltypes of gypsum board arerecommended. This system features Sta-SmoothBrand gypsum board with aunique edge. The two edgeconfigurations relieve jointdeformity problems causedby twisted framing,damaged gypsum boardedges, poor alignment andextremes in humidity andtemperature. Regular Sta-Smooth Boards areavailable in 1/2" thicknesses, 4' wide and incustomary gypsum boardlengths. The Sta-SmoothSystem is also composed ofProForm BRAND Sta-SmoothJoint Compounds, ahardening-type tapingcompound and regularGold Bond tape andfinishing compounds.

ADVANTAGESImproved Durability – The

Sta-Smooth System produces a smooth, flat,durable surface that relievesbeading, ridging and otherjoint deformity problems.

Greater Speed – All flat joints in the Sta-SmoothSystem are filled and tapedwith any Sta-SmoothCompounds all in one easyoperation, the same as conventional gypsum boardapplication methods. Sta-Smooth Compounds or regular compounds can beused to tape inside corners,cornerbeads, and spot fasteners. Regular ProFormfinishing compounds orSta-Smooth compounds areused for the remainingfinishing coats.

Easier Handling – Theimproved edge designs onSta-Smooth Boards makeshandling easier with greatercomfort to the hands.

No Special Equipment – Allconventional fasteners,adhesives, and gypsumboard application tools (T-squares, knives, etc.) can beused to apply Sta-SmoothBoards. Nothing new tobuy.

Alignment – Sta-Smoothboard with its unique edge(either configuration)allows for easy alignmentof the boards in the sameway as conventionaltapered edge board. Thetaper is scientificallydesigned to reducecrowned joints.

Stronger Bond – The bondingarea of the Sta-SmoothJoint Compounds areincreased with the “V”edge boards. The Sta-Smooth Joint Compoundused to bond the joint tapeand fill the joints is a hardening-type, high density material with low shrinkage characteristics.

Strength – The Sta-Smoothjoint shape and the jointcompound are developedto provide greater massand integral bond forincreased strength. Sta-Smooth Joint Compoundsadd considerable strengthwhich is unaffected by the amount of moisturenormally introduced into astructure that could causeridging or beading withconventional joint compounds.

Cost – If application techniques are followed asrecommended, the Sta-Smooth System should costno more and can cost considerably less than conventional gypsumboard drywall jointfinishing. The initialsavings are immediatelydemonstrated with reducedtravel time that results fromthis perfected 2-trip, 3-stepjoint finishing system.Future cost savings will berealized with reduced callbacks.

Better Butt Joints –Recommended with the Sta-Smooth System is animproved technique forproviding a smoother, flatter, stronger butt joint.Although this techniquecould be used in conventional drywall work and produce betterbutt joints, it is furtherimproved by the use of thehigh strength Sta-SmoothCompound.

Note: Sta-Smooth Gypsum Board may be used with any of theGypsum Drywall Systems described in this GypsumConstruction Guide.

All specifications for the application of gypsum board asdescribed in this literature may also serve for the applicationof Sta-Smooth Boards. Any deviation from thesespecifications is as indicated below.

A. BOARD APPLICATION: Position each Sta-Smooth Board sothat the long edges are in light contact with the edges of theprevious boards. All boards positioned to form butt jointsshould have a gap approximately 1/16" between the boardends. This spacing can be assured by driving 2 extra fastenersat the end of the board to act as temporary spacers beforeabutting the next board. When the boards are fastened inplace, drive the temporary spacers flush with surface. Whengypsum board is applied horizontally, recess all butt joints onthe job by shimming the face of the studs (or joists), on bothsides of the studs (or joists), on which the joint will fall. Theshim can be pressed paper, thickness of building felt or other suitable materials not to exceed 1/16" thickness and as wide asthe stud or joist. It should be 6" longer than the butt joint andapplied to the face of the stud or joist with staples or nailsallowing the shim to extend under the edge of the abuttingboards of gypsum board to assure that the board facingsremain on the same plane.

B. CORNERS AND OPENINGS: All exterior corners and allopenings that require joint treatment should receive protective reinforcement of ProForm Multi-Flex Tape Bead orSteel Cornerbead or Steel Casing Bead as required.

C. TREATMENT OF JOINTS*: All flat Sta-Smooth gypsum boardjoints are taped with ProForm BRAND Sta-Smooth Compounds,making sure that a sufficient amount of compound is forcedinto the “V” joint and spread under the tape to form a solidfoundation for the finishing coats.**

1. As soon as the Sta-Smooth Joint Compound used for taping hashardened, the first finishing coat can be applied even whenthe Sta-Smooth Compound is still wet.

2. When the first finishing coat is completely dry the second finishing coat can be applied. Any of the ProForm JointCompounds may be used for the finishing coats.

3. Sta-Smooth Joint Compounds are recommended for the firstcoat on nail or screw heads. Regular finishing compoundsmay be used for subsequent spotting of the fasteners. Sta-Smooth Compounds are also recommended for the first coaton cornerbead and followed by one or more finishing coatsas required of regular ProForm Joint or Topping Compounds.

4. The inside corners may be treated with any of the ProFormJoint Treatment Compounds recommended for taping. If atwo-trip joint treatment operation is planned, the inside corners are taped with Sta-Smooth Joint Compounds. Thiswill permit finishing one side of the inside corners the firstday. Cornerbead is treated with Sta-Smooth Compounds if atwo-trip operation is employed.

*Alternate Method: When mechanical tools are to be used for taping joints, Sta-Smooth Compounds are used to fill the “V”joint only. Other ProForm Joint Compounds are then used tobed the tape and finish the joints. (See page 69.)

**Sta-Smooth, Sta-Smooth HS and Sta-Smooth Lite JointCompounds are recommended for pre-fill or tape/bed coatoperations in the Sta-Smooth system.

See page 63, Environmental Conditions and Limitations.

3. Second Finishing Coat

TAPING AND FINISHING WITH MECHANICAL TOOLSTaping – Taping tools such as the “banjo” and “hopper” types are recommended for

taping the flat joints with Sta-Smooth Compounds and the inside corners with ProFormregular joint compounds or with Sta-Smooth Compounds. Automatic taping tools arenot recommended for use with hardening-type compounds. Mechanical tools can beused for taping the inside corners when a ProForm regular joint compound is used.When automatic taping tools are used for taping the flat joints, the “V” formed by theedges of Sta-Smooth board on the flat joints and all spaces between the gypsum boardedges on butt joints are prefilled with Sta-Smooth Compounds and allowed to harden(30 minutes longer than the set time designated on the bag) prior to taping with aregular ProForm joint compound.

Finishing – Mechanical type finishing tools can be used in the normal manner for thefinishing operations of the Sta-Smooth System since conventional ProForm finishingcompounds are used.

MIXING INSTRUCTIONSProForm BRAND Sta-Smooth Compounds are available in 20, 45, 90 and 210 minute set

times. MIX NO MORE COMPOUND THAN CAN BE APPLIED IN THE DESIGNATEDSET TIME. Contact your National Gypsum Company Representative for availability. A plastic container is recommended because of its ease in cleaning between batches.Do not use a wood or aluminum bucket. Add the compound gradually to clean waterwhile stirring. Note: Use only fresh, clean water suitable for human consumption. Mix at the ratio of 13-14 pints of water to the 25 lb. bag. Mix the compound free oflumps with a mechanical mixer or by hand. Mechanical mixing is recommended.Allow to stand 5 minutes as a “wetting” period and remix to further improve theworking qualities. If a slightly thinner compound is desired, add an additional pint ofwater, or less, after the compound is thoroughly mixed.

INSTALLATION

APPLICATION AND FASTENINGSta-Smooth Boards may be nailed, screwed or adhesively applied to wood studs or

furring, or screwed or adhesively applied to steel studs or furring, using conventionaltype and length of fastener. All fasteners shall be applied a minimum of 3/8" (maximum 1/2") from the edges and ends of each board. Then treat the joints in three simple steps.

CONVENTIONAL TAPING AND FINISHING1. Fill Joint And Bed Tape SimultaneouslyAll flat gypsum board joints are to be filled and taped in one operation with ProForm

BRAND Sta-Smooth Compounds, using ProForm Paper Tape in the conventionalmanner. When Sta-Smooth HS tape is used, the self-adhering fiberglass mesh tape isfirmly pressed to the gypsum board, spanning the joints. Sta-Smooth Compounds canthen immediately be applied to the joints. The compound must be forced through thetape to fill the channel formed by the “V” edges of the Sta-Smooth gypsum board. Allinside corners may be taped using regular ProForm compounds. Sta-SmoothCompounds are used for the first coat on nail or screw heads and will decreaseproblems with fastener imperfections. Inside angles, first and second finishing coatsmay be done using regular ProForm joint compounds.

2. First Finishing CoatAs soon as the Sta-Smooth Compound used for taping has hardened, the first finishing

coat may be applied on the flat joints even before it is dry. Any ProFrom joint compound may be used for this operation. A second coat may be applied at this timeto nail or screw heads, one coat on cornerbead if Sta-Smooth Compound was used forthe first coat.

3. Second Finishing CoatAs soon as the compounds used for the previous steps have thoroughly dried, a second

finishing coat is applied to all flat joints using ProForm Joint Compound or ToppingCompound. A third coat is applied over nail or screw heads and on cornerbead asrequired. The unfinished side of the inside corners is also finished at this time.

STA-SMOOTH ROUND EDGE REQUIRES PRE-FILLING PRIOR TO BED & TAPINGApplication Instructions For Round Edge Sta-Smooth Gypsum Board1) Mix Sta-Smooth Joint Compound, Sta-Smooth Lite Joint Compound or Sta-Smooth HS

Joint Compound as per bag instructions. Care should be taken to mix no more compound than can be applied in the designated set time.

2) Pre-fill all joints formed by the abutting round edge Sta-Smooth Gypsum Boards withSta-Smooth Compound, Sta-Smooth Lite Joint Compound or Sta-Smooth HS JointCompounds using a conventional joint finishing knife. Fill joints, level and wipe offexcess compound to the lowest level of the taper, allowing enough room for embedding the tape. Allow prefill material to harden prior to application of tape andbed coat.

3) Finish joints in the normal manner.

sent the results of tests onassemblies made up ofmaterials authorized byNational Gypsum in specific configurations. When selecting contruc-tion designs to meet certainfire requirements, caution must be used to ensure thateach component of theassembly is the one specified in the test. Further, precaution should be taken that assembly procedures are in accordance with those of the tested assembly.(For copies of specific tests,call 1-800-NATIONAL)

MOLD AND MILDEWRESISTANCEShaftliner XP was designed to

provide extra protection against mold and mildew.

When tested by anindependent lab per ASTMD3273 (Standard TestMethod for Resistance toGrowth of Mold on theSurface of Interior Coatingsin an EnvironmentalChamber), Shaftliner XPachieved a score of 10, thebest possible score for thistest.

The use of Shaftliner XP inactual installations may notproduce the same results aswere achieved incontrolled, laboratoryconditions. No material canbe considered “mold proof,”nor is it certain that anymaterial will resist moldindefinitely. When used inconjunction with gooddesign, handling andconstruction practices,Shaftliner XP can provideincreased mold resistanceversus standard shaftlinerproducts. As with anybuilding material, avoidingwater exposure duringhandling, storage andinstallation, and afterinstallation is complete, isthe best way to avoid theformation of mold ormildew.

RECOMMENDATIONS

Installation of 1" Shaftliner XPGypsum Panels should beconsistent with methodsdescribed in specificapplication details forCavity Shaftwall Systems, orH-Stud Area Separation WallSystems, or other fire-rateddesigns shown in NationalGypsum Company “GypsumConstruction Guide.”Exposure to excessive or continuous moisture orstanding water and extreme temperatures shouldbe avoided.To prevent weakening dueto calcining, 1" Fire-ShieldShaftliner panels, like anygypsum board, should notbe exposed to temperaturesover 125˚F (52˚C) forextended periods of time.Not to be used in an unlinedair supply duct.Always store Shaftliner XPGypsum Panels flat on alevel surface, and supportwith properly placed risers. to Growth of Mold on theSurface of Interior Coatings.

The facepaper is folded around thelong edges to reinforceand protect the core andthe ends are square-cutand finished smooth. Longedges of boards are slightlytapered, allowing joints tobe reinforced andconcealed with ProFormJoint Tape and JointTreatment Compounds.

1/4" High Flex Gypsum Boardis specifically designed forradius construction such ascurved walls, archwaysand stairways. It can beused for both concave andconvex surfaces. 1/4" HighFlex is typically applied indouble layers.

1/4" High Flex Gypsum Boardis a lightweight, cost-efficient material thatreadily accepts a widerange of decorativefinishes.

1/4" High Flex Gypsum Boardis easily cut for quickinstallation, permittingpainting or otherdecoration and theinstallation of metal orwood trim almostimmediately.

The gypsum core is non-combustible.

With joints reinforced byProForm BRAND JointCompounds, Gold BondGypsum Board forms wallsand ceilings exceptionallyresistant to cracks causedby structural and thermalchanges.

Expansion and contractionunder normal atmosphericchanges is negligible.

RECOMMENDATIONS

Installation of Gold Bond BRANDgypsum board should beconsistent with methodsdescribed in GA216

“RecommendedSpecifications for theApplication of GypsumBoard,” ASTM C 840,“Standard Specifications forApplication and Finishing ofGypsum Board,” andGA214, “RecommendedLevels of Gypsum BoardFinish.”

Exposure to extremetemperatures should beavoided. 1/4" High FlexGypsum Board is notrecommended where it willbe exposed to temperaturesexceeding 125˚F.

Installing 1/4" High FlexGypsum Board over aninsulating blanket, installedcontinuously across the faceof the framing members, isnot recommended. Blanketsshould be recessed andflanges attached to the sidesof the studs or joists.

For best painting results, allsurfaces, including jointcompound, should beclean, dust-free and notglossy. To improve fastenerand joint concealment, acoat of a quality latexprimer is recommended toequalize the absorptionbetween surface paper andjoint compound.

1/4" High Flex Gypsum Boardshould be applied first toceiling at right angles toframing members, then towalls. Boards of maximumpractical length should beused so that an absoluteminimum number of endjoints occur. Board edgesshould be brought intocontact with each other butshould not be forced intoplace.

1/4" High Flex Gypsum Boardis significantly more flexiblein the vertical direction(long edges parallel to theframing) than in thehorizontal direction. (SeeTable 1.)

Gypsum board joints atopenings should be locatedso that no end joint willalign with edges of openingsunless control joints will beinstalled at these points. Endjoints should be staggered,and joints on opposite sidesof a partition should notoccur on the same stud.

1/4" High Flex Gypsum Boardis typically installed indouble layer construction.To prevent flat spots,framing members should be

Installation of Hi-Abuse XPGypsum Board should be consistent with methods described in the standards references noted. For bestperformance, use verticalapplication.

GridMarX®

Hi-Abuse® BRAND XP GypsumBoard comes standard with GridMarX® guide marksprinted on the paper surface.These guide marks align withstandard building dimen-sions and help to quicklyidentify fastener lines for studand joist framing. Using GridMarX, accurate cuts canbe made without having to draw lines. The use of GridMarX also provides quick identification and uniform nail/screw patterns.

GridMarX guide marks run themachine direction of the board at five points in 4"increments. Marks run alongthe edge in both tapers andand at 16", 24" and 32" in the field of the board. The marks cover easily with nobleed-through using stand-ard products.

Vertical Application - In a vertical application, GridMarX serves as a guide mark to help identify the exact location of framingmembers behind the gypsumboard, eliminating the needfor field-applied vertical lines.

Horizontal Application - In a horizontal application,GridMarX serves as a reference mark to helpidentify the location of framing members behind the gypsum board. (If framingmember is located 2" to the right of the GridMarX at thetop edge of the board, it willbe located 2" to the rightdown the face of the board.)

Provides greater resistance to surface abuse, indentationand impact than fiber-rein-forced gypsum panels.

Hi-Abuse XP smooth facepaper is highly resistant toscuffing when sandinggypsum board joints and fasteners providing a superior surface for deco-ration.

Gridstone® BRAND Ceiling Panels

DESCRIPTION TECHNICAL DATA

Gridstone® BRAND prefinished ceiling panels have a non-combustible, Fire-Shield G gypsum core. The 2-mil white, stipple-textured vinyl laminate combines high light reflectance with easy cleanability.

Gridstone panels can be used for interior and exterior ceiling applications.

Gridstone Ceiling Panels install easily in standard 2' x 2' and 2' x 4' exposed grid systems. Ceiling panelshave a rigid gypsum core which provides extra resistance to sagging and warping.

A noncombustible gypsum core ensures fire safety with1 1/2- and 2-hour fire rating achievable depending on installation.

The sturdy white vinyl laminate eliminates additional finishing.

As little as 1" of material can be cut from Gridstone panels with practically none of the crumbling common with mineral fiberpanels.

For exterior application, protect grid panels from direct exposure to weather, water and continuous high humidity. Under no circumstances should water be in contact with the back of the panels.

Overlaid insulation may causeexcessive panel deflection and is not recommended where high humidity is likely to occur.

Extreme lighting conditions may distort texture appearance.

The use of strong organic solvents (such as ketones), harsh abrasive cleansers or steel wool are not recommended. These materials may cause dulling, discoloration, softening and other permanent damage to the vinyl surface.

USDA Acceptance: Gridstone panels are accepted by the USDA for use in food service and food processing areas.

RECOMMENDATIONS

Gridstone ceiling panels are designed to be mounted in standard 15/16" exposed tee grid systems or environmental type grids for severe conditions, with grids either 2' x 2' or 2' x 4'. Grid installation should be conducted according to manufacturer's specifi-cation.

Each panel must be supported on all four (4) edges.

Cross ventilation must be provided in unheated or enclosed space above ceiling panels.

General: Install panels in lay-in suspension systems with edges concealed by flanges of suspension members. Cut boards to fit tightly at borders and penetrations sothat cut edges are concealed by trim pieces and escutcheons.

Cleaning: Common dirt and stains on the vinyl surface can be removed with mild soap or detergent in lukewarm water. Use a light, scrubbing action with a cloth, sponge or soft brush.

If the suitability of any cleaning agent is unknown, check its effect on the Gridstone panel surface in a hidden area or on a scrap piece before attempting to remove a field stain.

Gridstone Ceiling Panels are not recommended for use in areas exposed to extreme or continuous moisture such as found in saunas, steam rooms, gang shower rooms or indoorpool enclosures, per ASTM C840 17.3.1.1.

DECORATIONGridstone Brand Ceiling

Panels are factory-finished decorative products which do not require painting. However, if desired, Gridstone can be painted with the following two products:1. Two coats of an alkyd or

Gold Bond® BRAND Foil Back Gypsum Board

DESCRIPTION LIMITATIONS1. Not recommended for

use where exposure to moisture and high outside temperature is extreme and continuous. Under these conditions, a qualified mechanical engineer should determine location of the vapor retarder.

2. Not to be used as a base for ceramic or other tile or as a base layer for prefinished vinyl wall boards in double-layer assemblies. Also, not to be used as a base for adhesively applied vinyl or other highly water-vapor-resistant wall coverings.

3. To prevent objectionable sag in ceilings, weight of overlaid unsupported insulation should not exceed:1.3 lb./sq. ft. for 1/2" thick boards with frame spacing 24" o.c.; 2.2 lb./sq. ft. for boards with frame spacing 16" o.c. Boards 3/8" thick must not be overlaid with unsupported insulation. Unheated attic spaces shouldbe properly ventilated.

4. Foil Back Gypsum Board is not recommended for use in hot, humid, climates such as the Southern Atlantic and Gulf Coast areas.

MATERIALSManufactured boards with

gypsum core, paper-encased with aluminum foil laminated backing.

SIZES AND TYPESThickness Width Length

1/2" 4' 6' to 16'5/8" 4' 6' to 16'

Edges: Square, tapered or Sta-Smooth.

APPLICABLE STANDARDSASTM C 1396

Gold Bond® Foil Back Gypsum Board consist of a fire-resistive gypsum core encased in heavy natural-finish paper on the face side and strong liner paper on the backside to which aluminum foil is laminated. The ends are square cut and finished smooth.

BASIC USESFoil Back Gypsum Board can be

used for exterior walls and ceilings in new construction and remodeling. The aluminum foil, laminated to the back surface, is a vapor retarder to keep interior moisture within the building at a suitable comfort level. Foruse with furred masonry, wood or steel framing, Gold Bond Foil Back Gypsum Board is effective for single-layer applications and as a base layer in double-layer applications where a vapor retarder of 1.0 perm or less is required.

ADVANTAGES1. In tests conducted according

to ASTM Test Procedure E 96 (desiccant method), 1/2" Foil Back Gypsum Board showed a performance of 0.06 perm compared to 34 perm for1/2" regular gypsum board and 28 perm for 1/2" gypsum board with two coats of flat latex paint.

2. In-place cost of Foil Back Gypsum Board installation is lower per thousand sq. ft. than a similar installation for regular gypsum board and polyethylene-film retarder installed separately.

3. Easy-to-handle Foil Back Gypsum Board is adaptable tovirtually all exterior wall and ceiling construction: wood frame, furred masonry.

Boards of maximum practical length should be used so that an absolute minimum number of end joints occur. Board edges should be brought into contact with each other but should not be forced into place.

Gypsum board joints at openings should be located so that no end joint will align with edges of openingsunless control joints will be installed at these points. End joints should be staggered, and joints on opposite sides of a partition should not occur on the same stud.

Gypsum board should be held in firm contact with the framing member while fasteners are being driven. Fastening should proceed from center portion of the gypsum board toward the edges and ends. Fasteners should be set with the heads slightly below the surface of the gypsum board in a dimple formed by the hammer or power screwdriver. Care should be taken to avoid breaking the face paper of the gypsum board. Improperly driven nails or screws shall be removed.

For best painting results, all interior surfaces, including joint compound, should be clean, dust-free and not glossy. To improve fastener and joint concealment, a prime coat of drywall primer is recommended to equalize the porosities between surface paper and joint compound.

FIRE RESISTANCE RATINGSFoil Back Gypsum Board has

not been used in fire resistance tests. Fire resistance ratings represent the results of tests on assemblies made up of specific materials in a specific configuration. When selecting construction designs tomeet certain fire resistance requirements, caution must be used to ensure that each component of the assembly is the one specified in the test. Further, precaution should be taken that assembly procedures are in accordance with that of the tested assembly. (For copies of specific tests, call 1-800-NATIONAL or 1-800-628-4662.)

RECOMMENDATIONS

Examine and inspect materialsto which gypsum board is to be applied. Remedy all defects prior to installation of gypsum board. Any defects in the finished installation due to misaligned framing or other cause will be the responsibility of the work performed under that section of the specification and such defects shall be remedied under that secton of the specification

Gypsum board should be applied first to ceiling at

right angles to framing members, then to walls.

and the steel studs acting asa composite section toprovide a maximumdeflection of L/120, L/240,L/360 (L = partition height ininches) with a horizontalload of 5 psf, 7.5 psf, and10 psf of partition surface.

Increased rigidity may beobtained by placingstiffener channels throughthe steel stud cut-outs, byusing two layer applicationof gypsum board or bydecreasing stud spacing.

Standard 25 and 20 gaugestuds, recommended forinterior partitions, haveheight limits as shown inTables 1 and 2. Gypsumboard must be attached tofull height on both sides ofstuds with Type S BugleHead Drywall Screws(Type S-12 for 20 gaugestuds) spaced not morethan 12" o.c. on all studswhen framing is 24" o.c.and 16" o.c. if framing is16" o.c. or less. Screwlengths must be not lessthan 3/8" greater than thetotal thickness of thegypsum board beingfastened.

Light steel 20 gauge studs aredesigned for exterior,nonload-bearing curtainwall systems, but are alsoused for interior partitionsto provide more ridigity orgreater heights than can beobtained with Standard 25gauge studs.

LIMITATIONS1. Maximum stud spacing for

single layer application of1/2" and 5/8" gypsumboard is 24" o.c. If 3/8"gypsum board is used, itmust be applied in twolayers, with the secondlayer adhesively applied;24" o.c. stud spacing maybe used.

2. Where long, continuousruns of this wall system areemployed, control jointsmust be provided every 30'or less.

3. Where structural movementmay impose direct loads onthese systems, isolationdetails are required.

4. Partitions should not beused where frequentlyexposed to excessivemoisture unless all surfaces

are waterproofed.5. To prevent weakening

due to calcining, gypsumboard should not beexposed to temperaturesover 125˚F for extendedperiods of time.

6. Gypsum board joints onsingle layer, or the facelayer on two layerapplications, shall notoccur within 12" of thecorners of door framesunless control joints areinstalled at the corners.

7. For limitations regardingselection of doors anddoorframes, refer to tableon page 92.

8. Where reference is madeto nominal gauges, 25gauge relates to aminimum base steel of.0179", and 20 gauge to.0329".

RECOMMENDATIONS

1. FRAMINGAlign floor and ceiling tracks to ensure plumb partition.

Secure track with suitable fasteners at a maximum of 24"o.c. Position studs in track on 16" or 24" centers byrotating into place for a friction fit. Steel studs shall beinstalled with all flanges pointed in the same direction.Secure studs located adjacent to door and window frames,partition intersections and corners with 3/8" Pan HeadType S Screws driven through both flanges of studs andtracks or by using a stud clincher.

2. SINGLE LAYER OR FIRST PLYCut gypsum board to allow for a 1/8" to 1/4" gap between

gypsum board and floor to prevent potential wicking.Apply gypsum board with the length parallel or at right angles

to the studs. Center abutting ends or edges over the studflanges.

For metal framing, screws shall be Type S, of a length toprovide not less than 3/8" penetration into framing andshall be spaced 24" o.c. max. If no adhesive is used,standard fastener spacings shall prevail.

For non-fire-rated construction, locate all attaching screws12" o.c. when framing is 24" o.c. and 16" o.c. whenframing is 16" o.c. or less. For fire-rated construction,vertical application, space screws 12" o.c. in the field and8" o.c. along the vertical abutting edges unless otherwisespecified. Attach the gypsum board to Steel Studs withType S Drywall Screws using an electric, drywallscrewdriver with a #2 Phillips bit. For vertical gypsumboard application with studs 24" o.c., erect the gypsumboard on one side of the partition, screw attaching to openend of stud flange first at vertical gypsum board joints.Complete the gypsum board application to the entire sideof the partition in this manner. For the opposite side, cutthe first gypsum board 2' wide so that joints will bestaggered. Fasten this and succeeding gypsum boards to allstuds on this side. When partition face is complete, returnto the first side and complete screw attachment of gypsumboard to all intermediate studs.

Make door and window framing openings of such size thatwhen the gypsum board is secured to the studs, it will fitsnugly into the steel frames.

3. FACE LAYERMechanical attachment of face layer for fire or sound rated

constructions shall be made in accordance with thespecifications for the system selected. When the face ply isattached with mechanical fasteners and with no adhesivebetween plies, the maximum spacing and minimumpenetration recommended for screws should be the sameas for single ply application.

DESCRIPTION

STANDARD APPLICATIONStandard application (single

nailing) Regular Gold BondGypsum Board is usuallyapplied directly to woodframing members. Ceilingsare applied first, thensidewalls. Boards should beaccurately cut and jointsabutted but not forcedtogether. Horizontalapplication, long edges atright angles to nailingmembers, is preferred for itminimizes joints andstrengthens the wall orceiling. Nails shall bespaced not to exceed 7" onceilings, or 8" on sidewalls,a minimum of 3/8" and amaximum of 1/2" fromedges and ends of gypsumboard. Gypsum board nailsor annular ring nails, suchas the GWB-54 illustratedabove, are recommended.For a description of thevarious types of Gold BondGypsum Boards, refer topages 58 through 89.

DOUBLE NAILINGDouble nailing is an alternate

method of attachmentdevised to minimize nail-pops. This system requiresdoubling up on the fieldnails. The total quantity ofnails used does not double,however, since maximumnail spacing is increased to12" o.c. and conventionalnailing is used on theperimeter. Application isaccomplished by first singlenailing the field of theboard, starting at the centerand working toward endsand edges. Another nail isthen driven in closeproximity (2" to 2 1/2") toeach of the first nails. Thefirst series of nails are thenstruck again to ensure theboard is drawn tightly tothe nailing member.

FLOATING ANGLEMETHODFloating angle method of

gypsum board applicationeliminates the use of theperimeter nails at interiorcorners and where ceilingsand walls meet. Thismethod reduces the stressand strain on the board ifframing settles.Reference ASTM C 840,Section 9.

ADHESIVE NAIL-ONMETHODApply drywall adhesive to

face of studs or joists incontinuous beads.Reference ASTM C 840Section 10.

FIRE RESISTANCE RATINGSWhere fire ratings are

required, refer to pages 12, 13, 22, and 23. Forcomplete constructiondetails consult the specifictest report.

SCREW APPLICATIONScrew application is often

preferred as the screwholds the gypsum boardtight against the framingwhen applied asrecommended. Type W 1 1/4" Drywall Screws aredriven with an electricscrew gun equipped withadjustable screw depthcontrol and a #2 Phillipsbit. If framing is spaced upto 16" o.c., screws arespaced 12" o.c. max onceilings and 16" o.c. maxon walls. If framing isspaced 24" o.c., screwspacing must not exceed 12" o.c. Minimum screwpenetration shall be 5/8" forwood studs.

RECOMMENDATIONSCut gypsum board to allow for

a 1/8" to 1/4" gap betweengypsum board and floor toprevent potential wicking.

1/2" or 5/8" gypsum boardsingle layer application isrecommended for interiorfinishing of all buildingswith wood frameconstruction. The use of

5/8" gypsum board or 1/2"High Strength CeilingBoard on ceilings willminimize sagging. Duringcold weather the use ofpolyethylene film as aceiling vapor retarder is not recommended unlessceiling insulation isinstalled prior toapplication of gypsumboard.

LIMITATIONS1. 1/4" Gold Bond Gypsum

Board should be appliedonly to existing surfacesand should not be applieddirectly to framingmembers, except whenused with other thicknessesin double layer systemstested for specific purposes.Existing walls and ceilingsshould be sound, flat, leveland without void spaces.1/4" thick gypsum boardshould be applied with acombination of mechanicalfasteners, nails or screws,and adhesive that will bondto the substrate surfacecovering. Nails or screwsshould penetrate framingspaced not over 24" o.c.Adhesive should be appliedbetween framing membersto bond the gypsum boardto the substrate.

2. 3/8" Gold Bond GypsumBoard should not be usedon nailing members over16" o.c. When applied toceilings, the gypsum boardmust be applied with thepaper bound edges at rightangles to the nailing mem-bers and shall not be usedto support insulation. 1/2"or 5/8" Gypsum Boardshould not be used onnailing members over 24"o.c. When applied toceilings with the nailingmembers exceeding 16"o.c., the gypsum boardmust be applied with thepaper bound edges at rightangles to the nailingmembers.

3. If gypsum board ceilingboards are nailed to crossfurring, these membersshall have a minimumcross section of 2" x 2"(nominal) with same

spacing limitations asabove. With screws,nominal 1" x 2" furring maybe used. Spacing of theframing members toreceive furring must notexceed 24" o.c.

4. In single ply installation, allends and edges of gypsumboard should occur overframing members or othersolid backing except wheretreated joints occur at rightangles to framing or furringmembers.

5. Hold the gypsum boardfirmly against the framingwhile fastening with nailsor screws. Start at thecenter and work towardeach end and edge,spacing the fasteners asrecommended for eachtype of application.

6. Lighting and other fixturesshall be supported byframing; do not use gypsumboard to support them.

7. Gypsum board ceilings tobe decorated with water-thinned spray texture shallbe 1/2" or 5/8" thick andapplied perpendicular tothe framing. Framing shallnot exceed 16" o.c. for 1/2" regular gypsum board and24" o.c. for 1/2" HighStrength Ceiling Board and5/8" gypsum board.

8. Gypsum board ceilings toreceive a spray texturefinish must be primed witha sealing latex primer andallowed to dry beforespraying. This is tominimize sagging of thegypsum board anddiscoloration problems.

The use of water-based spraytextures may cause un-primed gypsum board tosag when any one or moreof the following conditionsexist:

1. Unventilated buildings.2. Use of vapor retarders

under certain conditions.3. Periods of prolonged high

humidity due to eitherweather conditions orclosed building units (poordrying conditions).

4. Inadequate framing support(can occur where framingchanges direction).

5. Improper type or thicknessof gypsum board.

RECOMMENDATIONS

FLOATING ANGLESNo nails in shaded area.

SCREW APPLICATIONFast, positive, fewer heads to treat.

ADHESIVE/NAIL-ONIdeal for prefinished boards.

DOUBLE NAILINGMinimizes nail-pop.

SINGLE LAYER GYPSUMBOARD APPLICATION (alsoBase Layer of Double Layer)1. NAILSNails shall be GWB-54 or

cooler type located 3/8"min. to 1/2" max. fromedges and ends of board.Nails shall be a max. of 7"o.c. on ceilings and a max.of 8" o.c. on walls, exceptfor “Double Nailing”Procedure.

2. SCREWSDrywall screws for attaching

gypsum board to woodframing shall be 1 1/4",

Type W spaced not toexceed 12" o.c. on ceilings,16" o.c. on sidewalls wherestuds are 16" o.c. and 12"o.c. on sidewalls wherestuds are spaced 24" o.c.Screws for attachinggypsum board to gypsumboard shall be Type Gspaced as required.

3. STAPLESBase layer gypsum board may

be applied with power-driven staples spaced 7"o.c. on ceilings; 8" o.c. onsidewalls. Staples shall beU.S. Standard 16 gaugegalvanized wire staples

with 7/16" wide crownwith legs having divergentpoints. Legs shall be notless than 1" long for 3/8"base board, 1 1/8" long for1/2" base board or 1 1/4"long for 5/8" base board.

4. CORNERBEADSCornerbead shall be nailed

with gypsum board nailsspaced no greater than 9"apart on each flange of thebead with the nailsopposite. In lieu of nailing,cornerbead may be crimpapplied 6" o.c. with aspecial tool.

5. ADHESIVE APPLICATIONTO FRAMING

A. Apply gypsum boardadhesive to the woodframing with a caulkinggun.

FLOATING INTERIORANGLES To minimize fastener popping

in areas adjacent to walland ceiling intersections,the floating angle methodshould be used for eithersingle or double layerapplication of gypsumboard to wood framing.This method is applicablewhere single nailing,double nailing or screwattachment is used.Gypsum board should beapplied to ceiling first.

REPAIRING NAIL-POPS Nail-pops are caused by

lumber shrinkage afterboard application; loosegypsum board; improperlyaligned, twisted or bowedframing; or impropernailing.

Pops appearing before/duringdecoration should berepaired immediately.Those which occur afterone or more month’sheating are usually causedby lumber shrinkage andshould not be repaired untilafter heating season. Torepair, renail about 1 1/2"from the popped nail alongthe framing while applyingsufficient pressure adjacentto the nail to bring board infirm contact with theframing. If the popped nail

was improperly driven,remove it. If properlydriven, reseat just belowthe board face. Removeany loose material overreseated nail before treat-ing nail heads with jointcompound andredecorating.

ADHESIVE NAIL-ONAPPLICATIONThe adhesive nail-on system

for application of gypsumboard to wood framingmembers strengthens thewall and minimizes thepossibility of nail-popping.It reduces the number ofnails in the field, providesfor intimate contact and acontinuous bond betweenthe gypsum board andwood framing. All surfacesthat come in contact withthe adhesive should be dry,free of dirt, grease, oil orother foreign materials.

SCREW APPLICATIONDrywall screws attach gypsum

board to wood or steelframing or to other gypsumboards. They pull the boardtightly to the supports,minimizing surface defectsdue to loose boards. Whenproperly driven, they makea uniform depression freeof ragged edges and fuzz.

2. Adhesive Application ofFace Layer, General

a. All joints shall fall at least10" from parallel joints inthe base layer. Adhesiveshall be: (select one)

b. ProForm all-purpose readymix joint compound or Sta-Smooth setting typecompound applied with anotched spreader to theback side of the finishlayer.

c. Adhesive is applied with acaulking gun. Align boardedges. Reference ASTM C 840, section 9.

3. Adhesive Application,Regular Gypsum Board

The finish layer shall bepositioned on the wall orceiling within 10 minutes(unless otherwise specifiedabove) and held in placewith sufficient temporary(nails) (Type G DrywallScrews) (bracing) to ensureadequate contact andalignment of the gypsumboards. When the bond has developed (usually 24 hours) the temporary(fasteners) (bracing) shall beremoved. Resulting holesshall be filled flush to thesurface with JointCompound and the jointsshall be finished.Cornerbead shall beapplied at all exteriorangles.

4. Adhesive Application,Prefinished Gypsum Board

a. Pre-bow board by storingovernight in such a positionthat the ends of each boardcurve away from the baselayer when put in verticalmounting position.

b. Apply ready-mix or Sta-Smooth joint compound innominal 5" ribbons of four1/4" x 1/4" beads locatedaround the perimeter andcenter of the boards(approximate coverage forready-mix is 9-10 gal./1000sq.ft and Sta-Smooth is 50-60 lbs./1000 sq.ft.). Analternative is 2" diameterdaubs 1/2" thick, 16" o.c.(approximate coverage forready-mix is 5 1/2"-6gal./1000 sq.ft. and Sta-Smooth is 30 - 35 lbs./1000sq.ft.).

c. Temporarily brace, asrequired, to ensure propercontact and edge alignmentof boards.

5. Mechanical Application ofFace Layer

Mechanical attachment offace layer for fire or soundrated constructions shall bemade in accordance withthe specifications for thesystem selected.

For non-rated construction,nails used in wood framingto supplement adhesiveshall be type GWB, of alength to provide 7/8"minimum penetration intoframing and shall bespaced 16" o.c. max.Screws used in woodframing shall be Type W, ofa length to provideminimum 5/8" penetrationinto the framing and shallbe spaced 24" o.c. max. If no adhesive is used,standard fastener spacingsshall prevail.

Cut gypsum board to allow fora 1/8" to 1/4" gap betweengypsum board and floor toprevent potential wicking.

In double layer constructionuse any of the followingappropriate laminatingadhesives: (1) Sta-SmoothCompound or Sta-SmoothLite for fast hardening; (2) All-Purpose JointCompound for spreadingon the back surface of thefinish layer boards: (3)drywall adhesive meetingASTM C 557.

Base layer is applied onceilings, then sidewalls,secured with 1 1/4" TypeW Screws 12" o.c. onceilings, 16" o.c. on walls;nails located 7" o.c. onceilings; 8" o.c. onsidewalls; staples 5" o.c. onceilings and 6" o.c. onsidewalls.

Finish layer is temporarilynailed or braced untiladhesive dries. On walls,prefinished boards, appliedvertically, can be pre-bowed, nailed just top andbottom.

RECOMMENDATIONS1. Double layer gypsum board

application over woodframing is recommendedfor the ultimate in wallsurfacing and in areaswhere increased fireprotection and better soundinsulation are desiredbetween rooms. (For testresults see pages 13-14 ofthis guide.) Custom builthomes, commercialbuildings and party wallsbetween apartments wouldbe considered appropriateareas for double layerapplication.


09 29 00/NGC

2. Laminating is an excellentway to apply Durasan, thevinyl-surfaced gypsumboard. This methodeliminates any visible attachment.

3. Sta-Smooth Compound or Sta-Smooth Lite is recommended for laminating as well as forjoint treatment where fasthardening is required.

LIMITATIONS 1. Joints of succeeding layers

must not fall at the samelocation. For greateststrength, it is recom-mended that the boards ofeach layer be staggered sothat joints of each layer areat least 10" apart.

2. During cold weather, maintain a room temperature of not lessthan 40˚F during mechanical attachment ofgypsum board, andbetween 50˚F and 70˚F for 48 hours before lamination, joint treatment,texturing and decoration,and continuously thereafteruntil completely dry.

TYPICAL SECTION

Resilient Furring Channels arefabricated of galvanizedsteel with expanded metallegs that provide resiliencyto reduce soundtransmission through woodframed wall and ceilingassemblies.

STANDARD APPLICATIONResilient Channels have

punched holes spaced 1"o.c. in the leg flanges tofacilitate fastening toframing members spacedeither 16" or 24" o.c. The12' long channels areapplied perpendicular tothe framing members andspaced not more than 24"o.c. Gypsum board is thenattached to the ResilientChannels with powerdriven, Type S DrywallScrews spaced 12" o.c.

RECOMMENDATIONS1. Construction, as shown in the

detail below, is recommend-ed to achieve sound and fire-rating as shown on pages11-26.

2. A 3" wide strip of 1/2" thickgypsum board should beused at the floor line toassure a solid base forattaching the gypsum boardand the base. An additionalstrip of gypsum board or aResilient Furring Channelshould be used at theceiling line.

3. The point of intersectionbetween the wall and floorshall be caulked prior toapplication of baseboard toobtain the best soundisolation.

4. On wood studs fastenchannel through alternateflanges at each stud using 1 1/4" GWB-54 Nails orType W Drywall Screws.Fasten both flanges atchannel ends.

5. Resilient Furring Channelsshould be fastened to woodjoists with one Type WDrywall Screw at each joistin alternate flanges.Channel ends may fall onor between joists but mustbe fastened to prevent anysliding movement whichcould create squeakingnoises. When channel endsfall between joists, overlapapproximately 1 1/2" andscrew-attach through bothlegs into a wood block heldabove the channels, oroverlap approximately 6"and fasten both channelsnear ends with 3/8" Type SPan Head Screws.

LIMITATIONS1. Spacing of Resilient Furring

Channels should notexceed 24" o.c. nor spanmore than 24".

2. Use only 1/2" or 5/8"gypsum board with thissystem.

A. Z FURRING CHANNEL 1. Application of Foam.

Z Furring Channel is usedto secure rigid insulationand gypsum board tomasonry walls. Insulationthickness (1", 1 1/2", 2")determines depth of Zfurring web. The channel isapplied vertically andfastened to the masonrywall through the short (3/4")flange with suitablemasonry fasteners 24" o.c.maximum. Application isprogressive. After fasteningeach Z Furring Channel, a24" wide floor-to-ceiling-high insulation board is fitbetween the wall and thewide (1 1/4") flange.

2. Application of GypsumBoard. Erect Gold BondGypsum Board eithervertically or horizontally tothe Z Furring Channels.Gypsum board edges orends that run parallel to thechannels shall be centeredand abutted over channels.Fasten gypsum board with1" Type S Drywall Screwsspaced 12" o.c. Whengypsum board erection iscomplete, finish all jointsand screw heads inaccordance with ProFormJoint Finishing System.Prefinished gypsum boardmay be laminated verticallyto the channels with screwsat top and bottom.

Limitations Power driven fasteners should

be used to secure furringonly when wall ismonolithic concrete.Regular concrete nails canbe used for fastening to unitmasonry. If block is old,test nailing should be donein advance to determineoptimum size and type of nail.

B. LAMINATION 1. Application of Foam.

Insulation may be urethanefoam or extrudedpolystyrene. Expandedbead polystyrene is notrecommended. Forhorizontal gypsum board

application, install woodfurring strips (nominal 2"wide x 1/32" greater thanthe foam thickness)horizontally along the wall-ceiling and wall-floorangles, where horizontalgypsum board joints willfall, and around door andwindow openings. Forvertical gypsum boardapplication, furring stripsare required at thehorizontal wall-ceiling andwall-floor lines and arounddoor and windowopenings.

Masonry surface must be dry,clean and free of dust, dirt,form release agents, oil,grease or water solublematerials. Treat paintedmasonry as recommendedfor laminating to paintedsurfaces. Apply adhesive tothe foam insulation in 3/8"dia. beads continuouslyaround the perimeter andthrough the field in the longdirection with the beadsspaced 16" o.c. Contactadhesive manufacturer forcompatibility with foam.

Apply the foam boardshorizontally to the wallwith a sliding motion andhand press entire board toensure full contact ofadhesive and wall surface.

2. Application of GypsumBoard. ProForm All-Purpose Joint Compoundsmay be used. (Do not usewater base compounds forlaminating prefinishedboards to foam.)

Permanent nails or screws 12" o.c. are required tofasten gypsum board towood furring. Gypsumboard must be installed aminimum of 1/8" from thefloor. Use temporary nailsor bracing as necessary tohold gypsum board boardsin firm contact to the foamuntil adhesive has dried orset.

Limitations 1. Nails or screws used for

attachment of gypsumboard to furring strips mustnot penetrate through thefurring.

2. Power driven fastenersshould be used to securefurring to monolithicconcrete. Regular concretenails can be used forfastening to unit masonry. Ifblock is old, test nailingshould be done in advanceto determine optimum sizeand type of nail.

3. During cold weather, roomtemperature between 50˚Fand 70˚F must bemaintained uniformlyduring application anduntil adhesive is thoroughlydry or premises areoccupied. Provideadequate ventilation.

4. Gypsum board is notrecommended in areaswhere it will be exposed toexcessive moisture orcontinued high humidity.

5. Since the use of foamplastic insulation isregulated by many buildingcodes, consultation withlocal building authorities isrecommended beforeinstallation.

Since unprotected foaminsulation may represent afire hazard, it should becovered promptly andcompletely with gypsumboard.

INSTALLATION

Z FURRING CHANNEL HORIZONTAL INSTALLATION WITH DRYWALL ADHESIVE

DAUB METHOD USING JOINT COMPOUND

Z FURRING1. Begin application of

Z furring members bypositioning first piecevertically at a corner.Locate the piece on thewall adjacent to the wallbeing insulated first.

2. Insulation thicknessdetermines distance of Z furring web from wallbeing insulated. At theappropriate distance, andwith wide flange pointingtoward applicator, secure Z furring with appropriatefasteners through shortflange. (Note to Specifier:Power driven fasteners arenot recommended for usewith masonry block.)

3. Install 24" wide floor-to-ceiling insulation board,pressed snugly against webof first Z. Install next Z withwide flange overlappingedge of first insulationboard. Fasten to wallthrough narrow flange.

4. Continue in this manner,with Z furring 24" o.c. toend of wall. Locate last Zso that web is located adistance equal to insulationthickness from adjoiningwall. Cut last insulationboard to fit remainingspace.

5. At exterior corner, attachthe Z through its wideflange, with narrow flangeextending beyond thecorner. Begin with anarrow strip of floor-to-ceiling insulation, widerthan insulation thicknessbut not exceeding 3".Continue application offurring and insulationprogressively as describedabove.

6. At windows, doors and trimareas, use wood nailers(nom. 2" wide x insulationthickness plus 1/32"). Usethe nailers also at wall-floorangles to support trim andprovide backing for base.

7. Apply gypsum board with1" Type S Screws throughflanges of Z furring, 12" o.c.

LAMINATION1. Masonry or monolithic

concrete shall be abovegrade, dry, free of dust,loose particles, oil, greaseor other foreign material.

2. Joint compound used asadhesive shall be mixed toa consistency thick enoughto allow a 2" daub to stickto the underside of a broadknife held parallel to thefloor.

3. Apply 2" to 2 1/2" diameterdaubs of adhesive 1/2"thick, 16" o.c. in bothdirections to the masonrywall. The adhesive layoutmust provide for a row ofdaubs located a maximumof 2" from board ends, andcare must be exercised tocenter daubs on verticaljoints. No more adhesiveshall be applied to the wallthan will be covered withboard in 15 minutes.Approximate coverage forjoint compound (powder)used as an adhesive is 30-35 lbs./1000 sq. ft.

4. Cut gypsum board to allowfor 1/8" to 1/4" clearancebetween board and floor toprevent potential wicking.

5. Install gypsum board byhand pressing each boardtight to the wall makingcertain that all daubs are inpositive contact with theboard.

6. Support boards at eachcorner to keep them fromslipping to the floor by useof a concrete nail driventhrough a small block ofnominal 1" lumber.

7. Butt boards to eachpreviously positionedboard to ensure flush joints.

8. If necessary to hold boardsstraight, plumb and inproper alignment, drivemasonry nails throughsmall wood blocks and intomasonry at high pointsonly. After adhesive is dry(24 - 48 hours) removetemporary nails.

9. Fill all holes and treat jointswith tape and jointcompound.
