In vapour permeable constructions, there is no need to invest extra labour on installing a vapour barrier. The OSB-layer also provides a sufficient degree of airtightness on patched joints, installations and permeations. EGGER DHF is used on the outside of walls as an external diffusion-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. 6 1. Plaster boards 2. Insulated service cavity 3.

Larch wood planking high loadbearing capacity FACADE SYSTEMS – THE CHOICE IS YOURS 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 effect, 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 fulfilled using these systems. TICS (e.g. StoTherm Classic) INTERNAL WALL Its superb technical properties and varied formats even with tongue and groove profile 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 loadbearing structure to be optimised and thereby reduces the heat loss through the wooden supporting structure. Benefits on a view Brick cladding with air space easy handling improved noise control fastening with staples, nails and screws suitable for hanging shelves 05 Note CEILING AND FLOOR CONSTRUCTIONS The quality of living spaces depends on the quality of the sound insulation. A well planned construction can prevent any undesired influences and disturbances. The minimum requirements are set out in the relevant standards. Additional sound proofing requirements must be specially agreed with the developer.

Here the circumferential tongue and groove profile allows for easy, tight, installation of the boards for uniformly high sound protection. FULLY-INSULATED PITCHED ROOF Of all construction elements, the roof is the most exposed to weather and environmental influences. Its design and construction are therefore of particular importance. EGGER offers system solutions for this field of application. EGGER DHF is perfect for additional structural and fire protection requirements. Use of loft space as living quarters places whole new demands on roofs. Requirements such as summer overheating protection, thermal insulation in the winter, as well as appropriate sound proofing and fire protection can easily be met.

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 confirmed the suitability of EUROSTRAND® OSB 3 E0 and OSB 4 TOP for this area of application. CONSTRUCTION RECOMMENDATIONS Only use EUROSTRAND® OSB 3 E0 and OSB 4 TOP Board thickness ≥ 22 mm Recommended board size 2500 × 1250 mm Fasten the wall attachment/diaphragm attachment with ring nails (stainless steel) Moisture content of wooden construction (rafter) < 20 % Upper sided cover over the OSB with structured underlay, improves sound-proofing by up to 6 dB Correct construction planning and execution with regard to thermal insulation and moisture protection Observe any fire protection requirements (airborne ember and radiating heat) Observe the recommendations of the metal roof and membrane manufacturers! ROOF CONSTRUCTIONS FOR HALLS WITH REQUIREMENTS TO FIRE RESISTANCE This panel type is offered in particular for the design of roof and floor constructions with wide spans and requirements of 30 minutes fire protection. Roof covering with EUROSTRAND® OSB 4 TOP 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, floors, 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 fire protection function of 33 minutes. 09 The assembly hall of the Pilatus Aircraft Ltd. in Stans, Switzerland, with an area of 8800 m² is built almost completely out of wood. The decision to use EUROSTRAND® OSB 4 TOP and EGGER DHF as structural sheathing of wall and roof beneath façade and metal roof cover was taken because of the outstanding technical performance of these panels. 10 EGGER ENGINEERED WOOD PRODUCTS FOR USE IN CONSTRUCTION Note In the context of the permission was regulated: ® EUROSTRAND OSB Design values for fasteners like screws, staples, and nails. That enables to design the distribution of loads directly into EUROSTRAND® OSB is the right choice as a supporting and bracing element for walls and ceiling elements for all constructive applications with high load-bearing and dimensional stability requirements. Specially matched to the relevant field of application, the strength classes OSB/2 and OSB 3 E0 are available in accordance with EN 300 and OSB 4 TOP (with formaldehyde-free adhesive) in accordance with building regulations approval Z-9.1-566.

Vapour permeable and airtight constructions provide a long life span of the building. 14 PROCESSING RECOMMENDATIONS The following instructions also apply to EUROSTRAND® OSB and EGGER DHF. These are essential for correct use of the boards. max. 80 cm 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 flat 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 floor. 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 sufficiently high so as to prevent damage. The boards must be sufficiently 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 fluctuations. Before using the boards, a 48-hour period is recommended to allow the wood to acclimatise to local humidity. Remove the steel bands on site Package protected by film cover For acclimatisation on site: Boards propped up by battens For acclimatisation on site: Boards secured in the corner of a room 15 MOISTURE PROTECTION EUROSTRAND® OSB is characterised by low thickness swelling and a high degree of dimensional stability (see technical data: dimensional changes under influence 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 fit for use if installation is carried out correctly and no impermissible condensation can form. Before installation the following should be inspected on site: Board thickness Board type/permissible service class Compliance mark CE marking EQUILIBRIUM MOISTURE OF WOOD-BASED MATERIALS Relative humidity (RH) at 20°C Service class 1, 30 % to 65 % Dry conditions Service class 2, 65 % to 85 % Humid conditions Wood-based material approx. equilibrium moisture 4 % to 11 % 11 % to 17 % Dry screeds consisting of wood-based materials should only be laid in enclosed buildings once windows and doors have been fitted. When installation is carried out in rooms without a cellar below, ensure sufficient thermal insulation to prevent condensation forming on the underside of the board and possible warpage to the floor. In the case of concrete ceilings install a vapour barrier first. PE film with d > 0.2 mm which overlaps joints by 30 cm and can be installed right up to the upper edge of the floor is suitable. The board moisture should correspond to the local humidity where it will be installed. In the case of floor 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. The use of EUROSTRAND® OSB as a vapour control layer at the inside of vapour permeable constructions guarantees a sufficient high safety against condensation risk. 16 Application Installed dry, no moisture during usage. Occasional increase in humidity during use; Installed externally under roof. No direct weathering. Wood and wood-based materials must not take in moisture from the surrounding construction components. If the floor cannot be immediately installed after the dry screed has been laid then the board surface must be covered with a PE film or other suitable material to prevent it drying out or becoming more moist on one side, leading to deformation (cupping, buckling). DISPOSAL In its delivery condition, wood waste can be used as a material or for the production of energy. In this case it is classified 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.

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 flat-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 outermost board edge. The thick core-layer structure ensures a high withdrawal strength around the edges. dn Nail diameter 150 IF BOARDS WILL BE VISIBLE ONCE INSTALLED, NOTE THE FOLLOWING FOR A GOOD CUT: Sharp tool Workpiece must not vibrate Correct saw blade overhang Select a slightly lower feed rate compared to solid wood.

EDGE DISTANCES/EXPANSION JOINT FLOOR/ROOF, CEILING 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 flooring. Skirtings must be fitted so that the floor has adequate ventilation. Glued plastic skirtings are not suitable. Trusses, etc. in the space should be sufficiently exposed. In areas with edge lengths > 10 m, expansion joints that are permanently elastic should be arranged. Glueing of tongue and groove WALL In the case of walls with edge lengths > 10 m expansion joints approx. 10 – 15 mm wide should also be added. FLOOR INSTALLATION The installation of the wood-based panels is carried out by joining them together and therefore requires hardly any cutting in the case of floating installation. Cross joints must not be formed. Panels must be offset by at least 40 cm. Tongue and groove panels can be fitted in the adjacent wall area by simply putting them in at an angle in the groove. Free floating 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 floorboards, first 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. Laying with the T&G Quick profile BOARD THICKNESS In the case of floating 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. SUBCONSTRUCTION FOR CERAMIC FLOOR COVERING The EUROSTRAND® OSB boards must have a board thickness of at least 25 mm for floors and 18 mm in the case of walls and they must have high bending strength. The tongue and groove flooring boards must be glued under one another and pushed into place with force. They are screwed into the substructure (see also fastening section). Deflection must not exceed e/600. When installing ceramic floors include permanently elastic expansion joints every 3 – 4 m. 19 EGGER DHF – SPECIAL INSTRUCTIONS EGGER DHF AS SUB-ROOFING ON THE RAFTERS 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). 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). UNDERLAY CLASSIFICATION As interlocked underlay of the type UDP-A (rigid underlay, type A, with circumferential tongue and groove profile), 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. 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 EGGER DHF used as rigid underlay ADDITIONAL GLUING 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°. TRANSIENT WEATHERING After installing EGGER DHF the roof covering/facade should be fitted 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 diffusion 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 fitted boards have to be protected from natural weathering. Note 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 diffusion characteristics of exterior sheathing, which may result in moisture damage. UNINSULATED COCK-LOFT The roof area of an uninsulated cock-loft and an unconverted attic must also be ventilated even by using a vapour permeable sub-roofing material. The recommended ventilation cross-section, derived from the regulations for the ventilation of flat roofs is 200 cm² per running meter at the ridge and the eaves. Ventilation of uninsulated cock-loft 20 DIMENSIONING Note Wooden 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 tables contain recommended values and are not intended as a substitute for individual verification by a structural engineer. 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.
