6 EARTHQUAKE PROOF Earthquake resistance of light frame systems shows excellent results with the use of Superpan Tech P5. Light frame structures have little mass compared to other structural types, making them particularly suitable for seismic risk regions. Their lightness and flexibility allow energy to dissipate. The Superpan Tech P5 board, as a structural enclosure wall, has been subjected to cyclic loading tests, certifying its good shear behaviour in the manufacture of lightweight material walls. These trials, conducted at the mechanical testing lab of the IVALSA Trees and Timber Institute, with the constructive system of RUBNER HAUS Spa, in accordance with EN 12512:2006 Timber structures - Test methods - Cyclic testing of joints made with mechanical fasteners, highlight the suitability of our Superpan Tech P5 board for construction in seismic risk areas. before after 6

7 WATER VAPOUR DIFFUSION RESISTANCE In using Superpan Tech P5 as a structural board in light frame enclosures, it is relevant to know the water vapour diffusion resistance in order to calculate the condensations. After having conducted tests in accordance with DIN EN ISO 12572, in April 2013, we can certify the following values: Superpan Tech P5 m Resistance factor to water vapour diffusion Sd [m] Equivalent air thickness for 19 mm thickness dry cup wet cup dry cup wet cup ,21 0,94 COMPARISON WITH OTHER WOOD PANELS Values according to EN m Sd [m] Type of board Resistance factor to water Equivalent air thickness vapour diffusion for 19 mm thickness wet cup dry cup wet cup dry cup OSB, 650 kg/m³ ,57 0,95 Particleboard, 600 kg/m³ ,29 0,95 Particleboard, 900 kg/m³ ,38 0,95 Fibreboard, 600 kg/m³ ,23 0,38 Fibreboard, 800 kg/m³ ,38 0,57 7

Fifty percent more resistance to bending in any direction. Transversally, Superpan Tech P5 triples its bending strength compared to an OSB board. The ability to install Superpan Tech P5 in any direction enables a better use of boards on site. With the same longitudinal elasticity as an OSB board, but with no chances of error during installation. A transversal elasticity 2.5 times higher than an OSB board. Lesser swelling ensures that the boards recover their original position after drying, so no sanding of the edges is required after installation, as with OSB boards. A tensile strength two times greater, which improves fixation of screws or nails, as it improves the tear strength. Guarantee of stability of all Superpan Tech P5 fixings under the influence of adverse weather conditions, thanks to greater tensile strength. Superpan Tech P5 has a surface quality that makes it optimal for any machining operation, a clear aesthetic advantage, which acquires an even greater value when painting, varnishing or coating the board, and that can hardly be found in other boards on the market. 8

9 APPLICATION GUIDE (according to ENV 12872:2000) STACKING Boards should be stacked horizontally upon flat surfaces, conveniently away from the ground and with a sufficient number of supports to prevent the lower panels from overload. Intermediate battens are recommended between every 15 to 20 panels for ventilation, in line with the lower vertical battens. It is recommended that the battens be placed parallel to the shorter sides and along the entire length of the stack. It is recommended that the ends not exceed 150 mm. When packets are stacked, it is recommended that the supports be aligned vertically to prevent warping. It is recommended that the top of the stack be covered. max. 150 mm max. 600 mm 15 or 20 boards STORAGE To be stored in closed dry areas, protected from the sun and rain, in compact stacks. To be protected from the effects of the sun, rain and chemical splash. It is not recommended to store the boards outside in the open air. CONDITIONING It is advised that the boards be packed according to the conditions of the place of application, because its moisture contents vary according to the hygrothermal conditions of the specific environment. The dimensions of wood-based panels increase when they collect moisture from the air, and decrease when they lose it. Excessive variations in moisture contents can cause unacceptable dimensional changes, which may involve curvature, distortion and opening of the joints between boards. Possibility of packing with dividing battens Dimensional variation corresponding to a 1% moisture variation of the boards Length % Width % Thickness % Previous conditioning reduces dimensional variations. 9

10 SUPERPAN TECH Forward direction SUPERPAN TECH Rotation of the disc Top or decorative side Forward direction Top or decorative side Rotation of the disc CUTTING AND PROFILING The machining quality of the surfaces decreases with increased moisture contents. When greater precision is required, it is recommended that the boards be cut to size after conditioning according to the moisture content of the end use. Mechanization with power tools The use of carbide or diamond tools and blades is recommended for increased service life. Saw blades with alternating teeth are recommended. It is recommended that circular saw discs are placed as low as possible in order to prevent chipping when the board comes out the back of the saw. If the speed is too slow, the cutting tools have an insufficient cutting load and tools wear out prematurely. If the speed is too fast, the edges become rough and fibrous. The position of the board during machine work is important. It is recommended that the boards be properly supported and pressed tightly against the cutting table and guides be used to prevent vibration. If it is a coated board, it is recommended to place the board in such a way that the decorative side is attacked first by the saw blades. MOUNTING It is recommended to preferably use ringed or helical shank flat head nails, or other types of improved nails or screws with higher anchorage capacity. Corrosion-resistant materials are galvanized steel or zinc, austenitic stainless steel, phosphorus bronze, and silicon bronze. It is recommended that the minimum length of such nails or screws be 50 mm or twice the thickness of the board, in case the latter dimension is bigger. It is recommended that the diameter of the nails or screws should be at least 0.16 times the thickness of the board. When fixing boards onto a metal structure, it is recommended to use self-screwing nails or screws. It is recommended that the screws be self-drilling and self-tapping slot head screws. It is recommended to embed the screws and nails about 2 mm to 3 mm below the surface of the board. When used as floor coating it is better not to seal the embossing holes. When used as floor coating it is better not to seal the embossing holes. 2 mm Unless structural calculations require separation or different distributions, the following is recommended: Maximum separation of fixation elements (mm) Minimum distance Distances between fixation Distance between fasteners on the to the edge of the elements around the perimeter joists, transoms or studs that work as board (mm) of the boards intermediate supports for the boards After fixation, it is recommended to protect the surfaces of the boards from damage caused by variations in humidity, sand and debris during construction work, by using polyethylene or suitable paper. 300 mm mm

11 WALLS USE CHOICE The boards must be chosen in accordance with EN The choice of a board for a structural enclosure wall upon studs depends on the required load stresses, on the axis spacing, on the mechanical properties and the service class. The use of Superpan Tech P5 is recommended only for structural wall enclosures corresponding to service classes 1 and 2. CONSTRUCTION OF WALLS Protective measures should be taken in the enclosure of the typical construction of an outer wall. The outer face of wall cladding panels is usually protected with a breathable membrane and coatings, such as brick, exterior wood sheathing, tiles or profiled metal sheets. We recommend creating a ventilated space between the coating and the outer face of the wall panels. We recommend mounting the outer coating to the studs of the structure, sandwiching a vapour barrier between the two. Façade Breathable membrane Exterior walls Thermal insulation Interior covering Vapour barrier Uprights Waterproof joint STARTING TO WORK min. 18 mm 3 mm Structure preparation It is advised to arrange the structure and studs perpendicular to each other, following the recommended dimensions and clearances. The studs surface and the structure must be levelled to ensure the proper attachment of the coating. It is recommended not to expose the panels and structural elements to more aggressive weather conditions than those they will endure during their service life. Prior to using the boards, it is recommended that the structural elements be conditioned to a moisture content as close as possible to the corresponding climate conditions of the structure in service. It is recommended that the edges of the panels rest on the studs at least 18 mm. Machine-worked edges The edges can be straight or tongue and grooved on two (TG2) or four edges (TG4). Straight-edge boards require a clearance between boards and all sides should be supported upon the structure, joists or rafters. Expansion clearances It is recommended that a 2-mm peripheral joint be left per meter length of wall. Assembling panels for walls upon studs Generally straight-edge boards are used for structural interior or exterior walls mounted upon studs. It is recommended that straight-edge boards be continuously supported around their perimeter. 11

12 .... Covering Wood framework USE IN PITCHED ROOFS Using Superpan Tech P5 to form pitched roofs in service classes 1 and 2. FUNDAMENTALS In pitched roofs, it is recommended to arrange the boards with staggered joints. Breathable membrane Superpan Tech P5 Air chamber Thermal insulation Vapour barrier In order to prevent condensation on the inner surface of Superpan Tech P5, ventilation is recommended. When panels are used in houses with pitched false-ceiling and insulation between the pairs, there must be adequate fresh air on the underside of the Superpan Tech P5 cover, above the insulation, ventilated from eaves to ridge and a vapour barrier in the warm side of the insulation. It is recommended to protect the Superpan Tech P5 from rain and accidental humidification during storage and to condition it adequately before using. Superpan Tech P5 STARTING TO WORK Structure preparation It is recommended to align and level the supporting edge joists, studs and braces. It is recommended that wood, wood-based panels and structural elements not be unnecessarily exposed to more aggressive climate conditions than those they will have to endure during their service life. Before using Superpan Tech P5, it is recommended that wooden supports be conditioned to a moisture content as close as possible to the corresponding climate conditions of the structure in service. Thickness greater than 30 mm Tongue and groove detail. 6.2 Thicknesses 16 and 19 mm. 6.2 Edge machine work Superpan Tech P5 TG4 is supplied with tongue and groove edges, avoiding the need for additional support for the larger sides. Expansion clearances Given the moisture content of Superpan Tech P5, it is necessary to leave an expansion joint. Special care must be taken when mounting in order to avoid bending. A clearance is recommended around the perimeter of the cover, with respect to the construction elements against which the enclosure abuts, or to allow possible expansion of the enclosure. At least 10 mm on each edge or 2 mm per meter length of board is recommended. 12 Bonding It is recommended to glue all joints of floor slab enclosures made with tongue and groove wood boards with a suitable PVAC adhesive or the like, to prevent noises in their use. Should you require an extra hold, you can use a D4 PVAC glue.all boards, either tongue and grooved or with straight edges, can also be glued to the supporting wooden joists. PVAC

13 INSTALLING SUPERPAN TECH P5 IN ROOF STRUCTURES We recommend placing Superpan Tech P5 TG4, tongue and groove, perpendicular to the rafters with the shorter sides supported upon rafters or upon other support edges. All perimeter edges of the board or those obtained from cutting should be supported upon studs or joists. The boards must be supported by at least 18 mm upon beams or rafters. It is recommended that the joints on the smaller side of the boards be placed alternately. min. 8 mm min. 18 mm 13
