Description

wedi building boards have a blue core made from CFC-free extruded polystyrene rigid foam. This makes the wedi building board an ideal basis for any type of plaster and tile. wedi building boards can be applied to practically any substrate, are waterproof, insulating, versatile, light and robust. The blue XPS core is 100% waterproof and remains fully functional even after possible damage. abP*: building board butt joints can be sealed 100% simply by using wedi 610. As no other seal is necessary, craftsmen benefit from increased security accompanied by a shorter tiling time. The cemented surface is a good adhesive under-surface. The fibre fabric also absorbs tensile forces. All building board systems have great heat insulation properties, Sound insulation DIN EN ISO 140-3 (at board thickness of 12.5 mm) - Rw, P 23 dB Fire behaviour EN 13501 - E Bending stress based on DIN 53293 - 3900 kPa (mean value) Adhesive tensile strength - 0,28 N/mm2 Linear coefficient of thermal expansion - 0,02 mm/(mk) Technical properties – Rigid foam Long-term compressive strength (50 years) ≤ 2% compression EN 1606 - 0,08 N/mm2 Compressive resistance or compressive strength at 10% compression EN 826 - 0,25 N/mm2 Associated modulus of elasticity EN 826 - 10 – 18 N/mm2 Tensile strength EN 1607 - 0,45 N/mm2 Shearing resistance EN 12090 - 0,2 N/mm2 Shear modulus EN 12090 - 7 N/mm2 Bulk density EN 1602 - 32 kg/m3 Resistance to water vapour diffusion(μ) EN 12086 - 100 Water absorption under long-term immersion EN 12087 - ≤ 1,5 Vol.-% Capillar action - 0 Linear coefficient of thermal expansion - 0,07 mm/mK Temperature limits - -50°C / +75°C Fire behaviour EN 13501 - E
