Usage
- 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. It is also suitable for tile and plaster carrier element.
