Installation overview

Thistle Multi-Finish or Thistle Board FinishTo provide a plaster skim finish.

or

Thistle DurafinishTo provide improved resistance to accidental damage.

or

Thistle Spray FinishGypsum finish plaster for spray or hand application.

Gyproc FireStripFor fire-stopping deflection heads.

Fixing and finishing products (continued)

Gyproc Control JointTo accommodate structural movement.

Gypframe Floor & Ceiling Channel is fixed at the head and base.Gypframe studs are fitted vertically to a friction-fit within thechannel sections, and to abutments, to form the framework.This allows for adjustment during boarding. Studs are fitted so asto all face the same way. Additional framing is installed as requiredto support heavy fixtures.

Boards are screw-fixed to framing members to form the lining.Horizontal board-end joints of face lining boards should be backedwith Gypframe GFS1 Fixing Strap (single and double layer) orGypframe GFT1 Fixing ‘T’ (single layer only).

OpeningsDetails for openings differ according to Duty requirements.See Design - Door openings later for further details.

ServicesElectrical and other services are normally installed after one side isboarded. Horizontal runs are routed through pre-formed cut-outsin the studs. Gypframe 99 FC 50 Fixing Channel can be installedbetween studs to support recessed switch boxes / socket outlets,or a high performance socket box detail used where higheracoustic performance is required.

TilingFor further details on tiling guidance -

Refer to section 13 – Finishing systems and decorative effects, Tiling.

For full installation details, refer to the British GypsumSITEBOOK, available to download from www.british-gypsum.com

Insulation products

Isover APR 120025mm, 50mm and 75mm, for improved acousticperformance.

1 The maximum heights quoted are limited by the fire state field of application or by limiting deflection of L/240 at 200 Pa, whichever is the more onerous.2 These systems have an ACTIVair option available for VOC control to improve indoor air quality. Refer to section 3 and section 14 for further details.

The fire resistance and sound insulation performances are for imperforate partitions, walls and ceilings incorporating boards with all joints taped and filled, or skimmedaccording to British Gypsum’s recommendations. The quoted performances are achieved only if British Gypsum components are used throughout, and the Company’s fixingrecommendations are strictly observed. Any variation in the specifications should be checked with British Gypsum.

6Please refer to section 3 - Basic principles of system design for general guidance

Design

Planning - key factorsThe position of services and heavy fixtures should be pre-determinedand their installation planned into the frame erection stage.

Partition to structural steelwork junctions

When designing the layout of rooms requiring separation by soundinsulating walls abutting structural steelwork, considerationshould be given to the potential loss of sound insulationperformance through the steelwork.

Refer to section 3.2.2 – Principles of building acoustics .

Cavity fire barriersMinimum 12.5mm Gyproc plasterboard, screw-fixed into the webof perimeter channels or vertical studs, will provide a satisfactoryclosure to flame or smoke.

Refer to section 10 – Cavity fire barriers .

ServicesPenetrationsPenetrations of fire-resistant or sound-insulating constructionsfor services need careful consideration to ensure that theperformance of the element is not downgraded and also that theservices themselves do not act as the mechanism of fire spread orsound transmission.

Refer to section 3.5 – Service installations .

Independent supportWhen designing for the installation of services such as firedampers and associated ductwork through a GypWall partition,consideration should be given to the size and weight of thedamper - this will determine whether it can be supported directlyfrom the partition or needs to be independently supported fromthe structure.

Refer to section 3.5 – Service installations .

ElectricalThe installation of electrical services should be carried out inaccordance with BS 7671. The cut-outs in the studs can be used forrouting electrical and other small services (see Constructiondetails – 1 ). Switch boxes and socket outlets can be supportedfrom Gypframe 99 FC 50 Fixing Channel fixed horizontally betweenstuds, or a high performance socket box detail used where higher

acoustic performance is required.

Where Gypframe AcouStuds are used, services are routed through50mm x 28mm ‘H’ shaped push-outs, at the same centres asshown in Construction details – 1a for conventional cut-outs.Cables should be protected by conduit, or other suitableprecautions taken to prevent abrasion when they pass through themetal frame.

Fixing floor and ceiling channelsGypframe Floor & Ceiling Channels must be securely fixed with arow of fixings at 600mm maximum centres. For 94mm channelsand above, two rows of staggered fixings are required, each row at600mm centres and each fixing 25mm in from the flange. If thefloor is uneven, a 38mm thick timber sole plate equal to the widthof the channel should be used.

If the concrete or screeded floor is new, consideration should begiven to the installation of a damp-proof membrane between thefloor surface and the channel or sole plate.

Door openingsThe designer should consider thickness tolerances of the partitiontypes in relation to the proposed door frame detail. Standard door

frame detailing to suit BS 5234 Light and Medium Dutyapplications is shown in Construction details – 24 . Detailing tosatisfy BS 5234 requirements for Heavy and Severe Duty is shownin Construction details – 25 - 26 . The door manufacturer shouldalso be consulted in relation to door details.

Framing surround for openingsWhere services such as horizontal ducts, fire dampers and accesspanels are required to penetrate the wall, their position should bepre-determined in order that a framed opening can be provided. Theopenings should be constructed using established metal studprocedures. See Construction details – 30 - 31 .

Control jointsControl joints may be required in the partition to relieve stressesinduced by expansion and contraction of the structure (seeConstruction details – 11 ). They should coincide with movement joints within the surrounding structure.

Deflection headsPartition head deflection designs may be necessary toaccommodate deflections in the supporting floor. Deflection headsmay also be required to the underside of roof structures subjectedto positive and negative pressures. Refer to Construction details –14 - 21.

For special detailing that minimises the loss of acousticperformance:

Refer to section 3.2.2 – Principles of building acoustics .

Access for maintenanceGyproc Profilex Access Panels are available to provide access formaintenance. Access panels must be fully compatible with drywallconstruction and match the fire rating of the partition.

FixturesLightweight fixtures can be made directly to the partition linings.Medium weight fixtures can be made to Gypframe 99 FC 50 FixingChannel. Heavyweight fixtures (to BS 5234) such as wash basinsand wall cupboards, can be fixed using Gypframe Service SupportPlate.

Refer to section 3.5.2 – Service penetrations and fixing intodrywall systems .

TilingFor further details on tiling guidance:

Refer to section 13 – Finishing systems and decorative effects, Tiling.

Board finishingRefer to section 13 – Finishing systems and decorative effects .
