2 GUIDELINES ROOF / WALL The following notes are to be considered absolutely Store the boards dry and before installation they have to be conditioned in the ambient climate Avoid damages to the edges When laying the tongue profile should face upwards Ensure the correct face is outwards on installation The boards should fit accurately Do not lay in cross joints. Stagge the butt joints in minimum of 30 cm Cut the boards with a conventional circular saw (middle size teeth) with dust suction Affix immediately to the stud or selected substructure Seal only with approved products o On AGEPAN THD T+G 230 and AGEPAN UDP only with primer The installation of structural components will be accomplished by an expert Contact: AGEPAN SYSTEM c/o GLUNZ AG Grecostraße Meppen Germany Technical Susanne Renz Tel. +49 (0) Mobil +49 (0) susanne.renz@agepan.de Commercial James A Hay Tel. +44 (0) Mobil +44 (0) jahassocs@yahoo.co.uk Page 2/9

3 AGEPAN - eco and safety efficient Nature is our inspiration Our objective is to enable people to live and work in an ecologically beneficial atmosphere using natural materials. Wood based products particularly when used in timber frame housing will have a positive effect on global warming by improved energy efficiency. The AGEPAN products as part of the AGEPAN building system may be used as a substitute for traditional timber frame constructions as well as for brick buildings manufactured using high energy process. AGEPAN s thermal insulation properties reduce energy emissions from housing, thus helping to minimise individual house energy usage and reducing emissions into the atmosphere. High quality standard o Monitored by external institutes o Produced according to German and European standards o CE marked by German quality controls The board in the system o Various and flexible application possibilities o All products of the structural system from one supplier o Products are co-ordinated Sevice of AGEPAN o Local service o Technical advice by qualified employees o Advice by a competent international hotline AGEPAN THD T+G 230 AGEPAN UDP AGEPAN DWD protect AGEPAN OSB Page 3/9

4 Aircontrol of the inside The impermeability is very important to reach a controlled heat and moisture insulation. The inner layer should utilise conducted airproofing with vapour barrier properties. To reach an inner airproofed layer you should take the AGEPAN OSB in conjunction with a permeable external planking. You have to seal the inner airproof layer on the joints and intersections. The following products are recommended: Ampacoll XT Airstop adhesive tape Airstop Flex adhesive tape SIGA Rissan SIGA Sicrall sigacover@siga.ch Windproof of the outside Insulation materials will only work properly if the inner and the external boards prevent airflow. The external boards must be windproof. Because of the four-sided tongue and groove profile of the AGEPAN THD T+G 230, AGEPAN UDP and AGEPAN DWD protect there is a an excellent wind tight barrier. Only trimmed joints and gaps or holes need to be sealed. You should use adhesive tapes which are work also on cold surfaces. Seal on AGEPAN THD T+G 230 and AGEPAN UDP only with previous primer. The following products are recommended (all products have to be dry and free of dust): Airstop bitumen tape with primer (AGEPAN THD T+G 230 and AGEPAN UDP) Airstop adhesive tape (AGEPAN DWD protect) Airstop Flex adhesive tape (AGEPAN DWD protect) Ampacoll XT (AGEPAN DWD protect) Ampacoll BK 535 (AGEPAN THD T+G 230, AGEPAN UDP, AGEPAN DWD protect always with primer) Terostat Sealing Tape (Fixband) BUDAX TOP Tescon N 1 With primer BUDAX AC SIGA Wigluv sigacover@siga.de Page 4/9

5 Weather exposure It is possible to leave AGEPAN THD T+G 230, AGEPAN UDP and AGEPAN DWD unprotected up to 8 weeks in the elements. It is important to install the counter battens and all waterproof all holes/gaps on the roof. If you expect snowfall install the battens immediately. Avoid any longer exposure to the elements. Should this situation arise protect the boards with a foil. For render protect by a foil in front of the scaffolding. AGEPAN THD T+G 230, AGEPAN UDP and AGEPAN DWD protect as second water layer / planking It is possible to install AGEPAN THD T+G 230, AGEPAN UDP and AGEPAN DWD protect as a second water protection layer. You do not require an additional foil. Because of the special tongue and groove connection of the AGEPAN THD T+G 230, AGEPAN UDP and AGEPAN DWD protect there is a high degree of wind- and waterproof protection. Only trimmed joints have to be sealed. Roof a) Second water protection layer with tongue and groove joints This is possible if the typical slope of roof is less than a 6. There are two possible methods. The AGEPAN THD T+G 230, AGEPAN UDP and AGEPAN DWD protect will be laid in bracing with the tongue and groove profile. The joints do not need to be sealed. Only holes and penetrations have to be sealed. You have to observe a minimum slope of the roof of 15. b) Sealed second water protection layer This is possible if the typical slope of roof is less than 6. There are three methods possible. Additional to a) above all joints must be sealed. You have to observe a minimum slope of the roof of 10. AGEPAN DWD protect and AGEPAN OSB as a structural board It s possible to use AGEPAN DWD protect and AGEPAN OSB as a structural board in the roof and in the wall. It iois permitted to use for bracing the studs and as a structural plank to withstand the wind load. The structural engineer has to provide the calculations. Anchorage AGEPAN THD T+G 230, AGEPAN UDP and AGEPAN DWD may be fixed by screws or by staples into the timber construction. This should be carried out directly after positioning. The final fastening of the boards may be by screws, nails or staples to the counter battens into the rafter. We advise stainless steel fixing materials. Page 5/9

6 The following fixing materials are recommended: ABC Spax-S Screw (Z ) - A screw with a bigger diameter of the screw head (no predrilling) Bierbach DaBau Screw (Z ) (no predrilling) Haubold Staple type BS A staple with a wide back (edge distance r > 30 mm, distance between the staples 65 mm, penetration depth > 30 mm) See also the chapter Guideline for Render System For AGEPAN UDP and AGEPAN DWD protect are recommended counter battens with size 30 x 50 mm, for AGEPAN THD T+G 230 counter battens with size 40 x 60 mm. Service layer It is possible to add the AGEPAN THD STD 190 with thickness of 40 or 60 mm and the AGEPAN UDP with thickness 22, 25 or 32 mm to the wood construction (with vapour barrier) or directly on the AGEPAN OSB. The AGEPAN THD STD 190 should be fixed with screws to the timber frame with a maximum distance between the studs of 62.5 cm. After this the chases / channel will be cut into with a router, a circular saw or a stanley knife. plasterboard should have a minimum thickness of 12.5 mm. The plasterboard is to be fixed into AGEPAN THD STD 190 and the AGEPAN UDP. A screw fixing would be possible only on the 60 mm board (Screw type, coarse thread: TN 3.5 x 45 or 3.9 x 45 GG). The maximum vertical spacing between the screws is less then 150 mm, the maximum horizontal spacing is less then 400 mm. It s possible to plaster the service layer directly with MARMORIT SM 700 or MARMORIT Rotkalk. Page 6/9

7 Guideline for Render System Fix the boards with 30 cm between the joints. Open joints, crossed joints, damaged spots, uneven areas must be avoided as should joins without T+G between the studs and deformations. In the area of windows and doors the AGEPAN UDP can be used in 25 mm. The AGEPAN THD N+F 230 boards have to be fixed with 6 rawl plugs/m² (approved screwing pegs with plastic cover with diameter of 5 cm) or with 10 V2A-stainless steel staples with a wide back/m² in a distance of 10 cm and mind. 30 mm of anchorage depth in the solid wood beams, even with the surface of the board. Other attachments are not permissible. The insulation boards must be dry, dust free, treated according to the manufacturer s guidelines and coated within 8 weeks after fixing. Dirty surfaces must be cleaned dry. The fibre boards may be used to 30 cm over the ground without and to 10 cm with special precautions. Connections at adjacent construction units and penetrations must be closed with MARMORIT joint sealing tape. As separation joint between render system to window and doors use the MARMORIT APU mesh border. At every external angles fix initially the MARMORIT angle mesh. 1 Final coat 2 Base coat 3 Mesh with 10 cm overlapping at the joints 4 THD N+F insulation board 5 Wood frame construction a = 625 mm 6 System anchor (THD-anchor set) MARMORIT SM 700 apply on thinly and rub in as a press priming into the boards, afterwards the first coat should be even and 5-7 mm thick. The interior corners are to be reinforced with an angle mesh or a mesh strip. At the corners of all building openings a reinforcing mesh strip becomes diagonal approx.. 30 x 50 cm attached. The mesh strip must start directly at the corner underneath the ordinary mesh. Subsequently embed in the reinforcing mesh, near the surface, free from creases and with 10 cm impact lap. Page 7/9

8 Final coats with granulation <2 mm (in accordance with DIN 18350, VOB part C, <3 mm) and felted or brushed structures a doubled mesh insert in the reinforcing mortar becomes necessary. As final coat the products: NOBLO; NOBLO light (mineral disk finery) with granulation 3 mm and painting of silicone resin EEC color; conni S 2/3 (silicone resin finery) or KATI S 2/3 (silicate finery) may be used. A primer may be necessary depending the used final coat and appropriate weather conditions. If discolorations by lignin or other components the primer ATON should be applied. As reinforcing mortars MARMORIT BASE SM is to be used in the splash-water range. The surfaces can be covered and felted after 5 days in a further processing step with BASE SM. Page 8/9

9 In the soil affected area a perimeter insulating board as well as a seal are to be utilised. Therefore the MARMORIT SOCKEL-Dicht in 2.5 mm layer thickness should be applied. 1 final coat 2 base coat 3 THD N+F insulation board 4 system anchor 5 end profile 6 gap gasket strip 7 wood frame constr. 8 any vapour barrier 9 flexible insulation 1 final coat 2 base coat 3 THD N+F insulation board 4 system anchor 5 end profile 6 gap gasket strip 7 mineral gasket seal 8 final coat with felt render and double painting (SOCKEL-SM, DER HAFTPUTZ) 9 base coat (SOCKEL SM) 10 drainage with felt 11 base insulation 12 flexible insulation 13 any vapour barrier 14 wood frame constr. 15 sealing of the building We would point out that with the existing design movements caused by drying out of the inserted materials; warming and humidity fluctuations within the building materials and the resulting shrinkage as well as moisture expansion the deformation by horizontal loads (wind load); extremely high diffusion, a swelling of the wood fibre boards may be possible. Subsequent injecting of loose insulation e.g. ISOFLOC, is to be avoided in principle. These approaches could cause tensions in the render system, leading to small cracks. Due to our trials the adherence of this guideline and the appropriate requirements are essential. The light reference value of 30 should not remain under. The technical instruction of the respective products must be followed. The feasibility must be examined on the spot before beginning of work. Technical changes we reserve ourselves up to a new edition. Page 9/9
