EGGER WOOD CONSTRUCTIONEXTERIOR WALL WITH 3 FUNCTIONS

FACADE SYSTEMS – THE CHOICE IS YOURS

INTERNAL WALL

As well as providing reinforcement, EUROSTRAND® OSB also acts as a vapour barrier (sd-value > 2.0 m). In vapour permeable constructions, there is no need to invest extra labour on installing a vapour barrier. The OSB-layer also provides a suffi cient degree of airtightness on patched joints, installations and permeations. EGGER DHF is used on the outside of walls as an external diff usion-open (sd-value < 0.2 m) and windproof layer behind a ventilated facade. This protects the structure during the construction phase, allowing interior work to proceed to schedule. Thermal insulation and sound insulation will be clearly improved compared to a vapor permeable cladding with breather membranes.

We have a variety of interesting cladding options for you to choose from. From the modern thermal insulation composite systems (TICS), with a classic rendered facade or a quarter-brick eff ect, through curtain wall facades to the popular wooden facades in the form of laths, planks or shingling. You can have any colour or type you wish. Even demanding architectural requirements can be fulfi lled using these systems.

Its superb technical properties and varied formats even with tongue and groove profi le make EUROSTRAND® OSB ideal for use in internal walls. With EUROSTRAND® OSB it is easy to attach loads such as cupboards or shelves to the wall surfaces without requiring special dowels. Another advantage of EUROSTRAND® OSB 4 TOP is that it gives you the option of reducing the distances between the nail and the edge of the board in question. This allows the wood cross section of the load-bearing structure to be optimised and thereby reduces the heat loss through the wooden supporting structure.

With a measured reduction in impact noise ΔLn,w = 20 dB in solid ceilings in accordance with DIN EN ISO 140-8 and excellent ΔLn,w = 7 dB in wood-beam ceilings following DIN EN ISO 140-11, suitable wood fi bre insulation board, in conjunction with 15/18 mm OSB fl ooring boards, are also suitable for fl oating fl oor systems on new builds, restorations and renovations. Here the circumferential tongue and groove profi le allows for easy, tight, installation of the boards for uniformly high sound protection.

Of all construction elements, the roof is the most exposed to weather and environmental infl uences. Its design and construction are therefore of particular importance. EGGER off ers system solutions for this fi eld of application. EGGER DHF is perfect for additional structural and fi re protection requirements. Use of loft space as living quarters places whole new demands on roofs.

SPECIAL APPLICATIONS

ROOF CONSTRUCTIONS FOR HALLS WITH REQUIREMENTS TO FIRE RESISTANCE

METAL ROOF COVERING ON EUROSTRAND® OSB

Roof constructions with metal covering and a subconstruction made of OSB boards have been successfully used for several years. Tests carried out by WKI Braunschweig on the withdrawal strength of fasteners and by I.F.I. Aachen on durability properties under dynamic wind loads confi rmed the suitability of EUROSTRAND® OSB 3 E0 and OSB 4 TOP for this area of application.

This panel type is off ered in particular for the design of roof and fl oor constructions with wide spans and requirements of 30 minutes fi re protection.

As T&G2-panel with the size of 3000 × 1250 mm the intended use of this panel is the installation of disk supported frameworks (roof, fl oors, walls) with large spans up to 1.50 m in particular for shop buildings. The panel has an optimal size of 3.0 m length which reduces waste when cutting to size.

Calculated according to EUROCODE EN 1995-1-2 the EUROSTRAND® OSB with 30 mm thickness and a burn-up rate of 0.9 mm/minute provides a fi re protection function of 33 minutes.

PROCESSING RECOMMENDATIONSThe following instructions also apply to EUROSTRAND® OSB and EGGER DHF. These are essential for correct use of the boards.

STORAGE AND TRANSPORT

Correct storage and protective measures during transport are essential for problem-free handling. The following simple principles should be taken into account:

EUROSTRAND® OSB and EGGER DHF should be stored fl at on several pieces of squared timber. The span width should be no greater than 80 cm and the pieces of squared timber should all be the same height. If several pallets are stacked on top of each other then

the squared timber should be aligned by height. Steel bands should be undone immediately in the fabricator‘s

storeroom to prevent compressive strain on the pallet. Upright storage (practically vertical) is only suitable for a

small number of boards on a dry fl oor. Tongue and groove boards In this case, only stand them on the groove side. In the case of transport by forklift truck the squared timber

chosen must be suffi ciently high so as to prevent damage. The boards must be suffi ciently protected against weathering

before being packed (closed lorry tarpaulin, polythene sheeting). Storage rooms should be uniformly air conditioned and free

from large moisture and temperature fl uctuations. Before using the boards, a 48-hour period is recommended

to allow the wood to acclimatise to local humidity.

Service class 2, 65 % to 85 %Humid conditions 11 % to 17 % Occasional increase in humidity during use;

Installed externally under roof. No direct weathering.

MOISTURE PROTECTION

EUROSTRAND® OSB is characterised by low thickness swelling and a high degree of dimensional stability (see technical data: dimensional changes under infl uence of moisture). When used as a supporting and bracing element, appropriate measures should be taken against weathering. According to EN/TS 12872 wood and wood-based materials with the following equilibrium moistures (see table) are fi t for use if installation is carried out correctly and no impermissible condensation can form.

Dry screeds consisting of wood-based materials should only be laid in enclosed buildings once windows and doors have been fi tted. When installation is carried out in rooms without a cellar

below, ensure suffi cient thermal insulation to prevent condensation forming on the underside of the board and possible warpage to the fl oor. In the case of concrete ceilings install a vapour barrier fi rst.

PE fi lm with d > 0.2 mm which overlaps joints by 30 cm and can be installed right up to the upper edge of the fl oor is suitable. The board moisture should correspond to the local humidity

where it will be installed. In the case of fl oor joists made of dry wood note that u < 15 %,

since shrinkage of the subconstruction can result in long-term squeaking noises. When using wet construction materials, such as plaster,

paint and wallpapering the resulting high humidity should be dispersed by adequate ventilation or other suitable means.

Wood and wood-based materials must not take in moisture from the surrounding construction components. If the fl oor cannot be immediately installed after the dry

screed has been laid then the board surface must be covered with a PE fi lm or other suitable material to prevent it drying out or becoming more moist on one side, leading to deformation (cupping, buckling).

EQUILIBRIUM MOISTURE OF WOOD-BASED MATERIALS

The use of EUROSTRAND® OSB as a vapour control layer at the inside of vapour permeable constructions guarantees a suffi cient high safety against condensation risk.

FASTENING

IF BOARDS WILL BE VISIBLE ONCE INSTALLED,

NOTE THE FOLLOWING FOR A GOOD CUT:

In its delivery condition, wood waste can be used as a material or for the production of energy. In this case it is classifi ed according to Appendix III of the Waste Wood Ordinance to (EWC Codes) 030105, 150103 or 170201. According to the waste code, it will be decided by local waste laws what form the disposal will take.

EUROSTRAND® OSB can be sawn and milled like solid wood using conventional electrical hand tools. We recommend the use of hard-metal cutting tools.

EUROSTRAND® OSB can be attached with all fasteners suitable for chipboard, such as screws, staples and nails. The length of the nail/screw should be 2.5 × board thickness – and at least 50 mm. With staples, a minimum wire gauge of 1.53 mm should be used. Corrosion resistant fasteners, e.g. made from galvanised or stainless steel, are to be used. Due to the high withdrawal strength, only fl at-head nails with gutter groove, screw nails or annularly threaded nails should be used (see also DIN 1052-2).The crosswise orientation of the strands in the EUROSTRAND® OSB creates a secure base for the fastener, even in the outer-most board edge. The thick core-layer structure ensures a high withdrawal strength around the edges.

Sharp tool Workpiece must not vibrate Correct saw blade overhang

Select a slightly lower feed rate compared to solid wood. Wear a respiratory mask if using hand tools without a dust extraction device. EUROSTRAND® OSB can be drilled with all suitable electronic and manual machines suitable for solid wood.

BOARD THICKNESS

SUBCONSTRUCTION FOR CERAMIC FLOOR COVERING

Detailed recommendations and basic rules for installation of wood-based materials for roofs, walls and ceilings can be found in EN/TS 12872.

The installed wood-based panels must have an extra space of ≥ 15 mm to the surrounding construction components. This extra space enables tension free work to be carried out on the panels as well as ventilation in the case of fl ooring. Skirtings must be fi tted so that the fl oor has adequate ventilation. Glued plastic skirtings are not suitable. Trusses, etc. in the space should be suffi ciently exposed. In areas with edge lengths > 10 m, expansion joints that are permanently elastic should be arranged.

In the case of walls with edge lengths > 10 m expansion joints approx. 10 – 15 mm wide should also be added.

The installation of the wood-based panels is carried out by joining them together and therefore requires hardly any cutting in the case of fl oating installation. Cross joints must not be formed. Panels must be off set by at least 40 cm. Tongue and groove panels can be fi tted in the adjacent wall area by simply putting them in at an angle in the groove. Free fl oating panel joints parallel to the supports are not permissible according to Eurocode 5 – Timber construction. Overhanging panels must be cut back to the size of the decking. The frame of the subconstruction should match that of the available panel sizes in order to minimise cutting. On old fl oorboards, fi rst check the old screws, and tighten them if necessary. Cut free any boards that are rubbing against each other. Be aware of functional adjacent construction.

In the case of fl oating installations with EUROSTRAND® OSB use a board thickness of ≥ 18 mm. In the case of high concentrated and individual loads use a board thickness of at least 25 mm.

The EUROSTRAND® OSB boards must have a board thickness of at least 25 mm for fl oors and 18 mm in the case of walls and they must have high bending strength. The tongue and groove fl ooring boards must be glued under one another and pushed into place with force. They are screwed into the substructure (see also fastening section). Defl ection must not exceed e/600. When installing ceramic fl oors include permanently elastic expansion joints every 3 – 4 m.

EGGER DHF – SPECIAL INSTRUCTIONSEGGER DHF AS SUB-ROOFING ON THE RAFTERS

UNDERLAY CLASSIFICATION

ADDITIONAL GLUING

EGGER DHF are vapour permeable underlay boards. They form a second water-repellent layer under the roof covering. They can be used on roofs with a minimum pitch of 16° with a max. 8° below the standard roof pitch (SRP) of the planned roof decking. They are installed with the tongue and groove joints from the eaves to the roof ridge, with tongues pointing towards the ridge. In the case of a shortfall of more than 8° the standard roof pitch must be a “rain and water tight subroof”. With a board thickness ≥ 15 mm EGGER DHF, as rafters, is walkable up to a rafter grid of 1 m acc. to ÖNORM B4119 (before ONR 22219-2 dry board).

As interlocked underlay of the type UDP-A (rigid underlay, type A, with circumferential tongue and groove profi le), the boards are assigned to Class 3 according to the ZVDH guidelines. EGGER DHF can be installed without an additional nail sealing strip under the counter-batten and without taping the tongue and groove joint, even in case of elevated requirements and with a roof pitch up to 8° less than the regulation pitch. Compliance with the minimum roof pitch of 16° is mandatory. Openings (for chimneys etc.) and joints (covings, groins, dormers etc.) must be taped using suitable adhesive tape.

A taped underlay must be implemented when the roof pitch is less than the regulation pitch of 16° by a maximum of 8°. All board joints are taped using suitable adhesive tape. The minimum roof pitch is 10°.

Increased requirements in addition to shortfall of standard roof pitch: Use of attic, especially as living space Special construction features, e.g. dormer windows, ridges, complicated roof shapes Climatic factors, e.g. mountains or coasts Local requirements, e.g. from building control

UNINSULATED COCK-LOFT

TRANSIENT WEATHERING

The roof area of an uninsulated cock-loft and an unconverted attic must also be ventilated even by using a vapour permeable sub-roofi ng material. The recommended ventilation cross-section, derived from the regulations for the ventilation of fl at roofs is 200 cm² per running meter at the ridge and the eaves.

After installing EGGER DHF the roof covering/facade should be fi tted immediately. Between March and November the boards can be exposed to natural weathering for 2 months as a temporary roof. In the winter months, structural measures must be employed to ensure that the external covering layer of EGGER DHF cannot freeze, since this would seriously impair the diff usion ability of the external panelling cladding and potentially lead to moisture damage. In the winter months it should only be exposed to natural weathering for a maximum of 2 weeks. If EGGER DHF is used for load-bearing purposes then the moisture protection regulations of the approval Z-9.1-454 apply and DIN 68800-2, i.e. the fi tted boards have to be protected from natural weathering.

Ventilation of uninsulated cock-loft

During the winter months, icing of

the outer layer of the EGGER DHF

board must be excluded by means

of suitable construction measures,

since this would severely impair the

diff usion characteristics of exterior

sheathing, which may result in

moisture damage.

Note

If the pitch of the roof is less then 8°

further measures should be taken

to ensure rain and water tightness

of the roof covering (i.e. taping the

EGGER DHF panel joints).

DIMENSIONINGWooden structures are designed according to the appropriate National and European standards. In the medium-term, Eurocode 5 has been introduced as an EU-wide regulation for the design of wooden constructions. Characteristic values for the structural design of EUROSTRAND® OSB in accordance with Eurocode 5 can be taken from DIN EN 12369-1 or from the building authorities.

The following assessment tables were created using the regulations for EUROSTRAND® OSB 4 TOP in accordance with approval Z-9.1-566 as well as the rules for the assessment of wooden constructions in accordance with Eurocode 5.

LOADING TABLES FOR EUROSTRAND® OSB

PRE-DIMENSIONING OF WALL PANELS FOR HORIZONTAL FORCE

The calculation is based on the regulations in DIN 1052-1:1988, section: 11.4.2 on the testing of tensile force on the board. To prevent the planking from buckling, the timber stud distances should be limited to ar = 83.3 cm.

* Panel with one, two or three timber stud distances ar. In the case of double-sided planking, double the permissible Fv(KN/ar) values.

WALL PANELS IN THE HEIGHT H UNDER HORIZONTAL STRESS

Horizontal force – allowable Fv(KN/ar)

ASSUMPTIONS

The longitudinal edge of the board runs parallel to the wall studs. There are no horizontal joints in the area. The nailing is carried out using staples with 1.8 mm wire gauges with a length of 55 mm and a clearance of 50 mm; N1 = 280 N permissible.

The tables contain recommended

values and are not intended as a
