New building board with factory-installed vapour barrier

wedi “BA Vapor” building board

The wedi “BA Vapor” building board with built-in vapour barrier is being introduced for all rooms subject to high vapour pressures and temperature differentials.
Already installed at the factory, the epoxy resin vapour barrier saves the craftsman valuable installation time, guarantees reliable sealing and makes it possible to apply high-quality wall covering rapidly. “BA Vapor” is suitable for all surfaces to be covered with ceramic tiles or plaster.
Especially in buildings with swimming pools, steam baths or communal showers, elevated air humidity is a permanent condition. Sound structural engineering principles require the addition of a vapour barrier when incorporating thermal insulation in such walls.
With the new “BA Vapor” building board, however, thermal insulation and the vapour barrier can be applied in a single step. wedi sealing tape is used to protect joint areas and openings against humidity and steam.

“BA Vapor” boards measure 2.50 x 0.60 metres and are available in thicknesses of 12.5 millimetres, 20 millimetres and 50 millimetres.
