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.
