Description

wedi building board Vapor is a composite element made from extruded polystyrene rigid foam which is reinforced on both sides with a special cement coating, with a vapour barrier on one side. For rooms where there is a permanently raised level of humidity For walls, ceilings and floors Vapour barrier and thermal insulation Vapour barrier (sanded epoxy-resin vapour barrier) - 1,5 mm Diffusion equivalent air layer thickness, sd value (epoxy resin vapour barrier) - 283 m Resistance to water vapour diffusion(µ) - EN 12086 188571 Fire behaviour EN 13501 - E 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 Propellant gas, carbon dioxide, GWP value - 1 The wedi building board Vapor may be used as heat insulation, while at same time, because of the coating applied in the factory; as a vapour barrier in rooms with permanently high humidity. Particularlwhen used for wall areas it is one of the best carrier elements on the market - especially when used for public shower and spa facilities.
