Building board Vapor
„The special building board for rooms with high humidity.“
Product information
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
All advantages at a single glance

Construction panels for rooms with high humidity: wedi building board Vapor
- 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.
