wedi Vapor 85 building board Waterproofing, vapour barrier and thermal insulation
Waterproofing, vapour barrier and thermal insulation
wedi Vapor 85 is both a board type sealing system and a building board with structural vapour barrier properties. Thanks to the pre-integrated
vapour membrane barrier applied in the factory it is perfect for challenging applications in areas with high levels of humidity.wedi Vapor 85 is made from blue extruded polystyrene hard foam (XPS) which is reinforced with alkali-resistant fibreglass mesh and coated with polymer-modified mortar on both sides, as well as a vapour membrane barrier on one side providing an SD value of 92.
wedi Vapor 85 is both a board type sealing system and a building board with constructional and vapour resistant properties which is specifically tested and approved for wall applications. It can be used on solid walls and stud frames, as well as on floors, in interior areas. Due to its special properties, it is versatile in its applications: • Carrier element for laying tile, slab and natural stone floor coverings using the thin-bed method, and surface for plaster and other materials • Vapour barrier • Effective thermal insulation • Compound seal with tile and slab coverings on wall surfaces Information about fitting, implementation of the sealing details and surface requirements can be found in the “wedi Vapor 85 building board application guidelines”.
