Application

wedi Building Board Vapor is approved for interior use on swimming pool walls and ceilings, steam baths, communal shower facilities and any areas where a vapour barrier is required for structural reasons when internal thermal insulation is installed. Use on floors is only approved if no wheeled loads or concentrated loads are expected.

Description

Composite board manufactured from extruded polystyrene (XPS) rigid foam, reinforced on both sides with a special cement coating and with a vapour barrier on one side. It is a tile and plaster carrier element for thermal insulation and simultaneous vapour barrier in rooms with permanently raised humidity. They can be fitted on almost any surface and are waterproof, heat-insulating, versatile and quick to process.

Features:

  • Adhesive surface for applying plaster, tile adhesive and other materials.
  • Carrier material for laying tiles using the thin-bed method.
  • Effective heat insulation.
  • Moisture protection.
  • Vapour barrier.
