Wedi building board has a blue core made from extruded polystyrene rigid foam which is free from HCFCs. This makes the wedi building board the ideal base for all plastering and tiling work. It can be put on almost any surface, is waterproof, heat insulating, light and stable and can be used in a variety of circumstances

What does wedi INSIDE have to offer?
The principle of wedi INSIDE is wonderfully simple: High-quality ceramic coverings require a completely secure surface underneath. For this reason, especially for use under tiles, tradesmen have been trusting wedi’s unique quality for decades. 100% waterproof and they are 100% sure of this – they guarantee it with wedi’s letter and seal!

The blue XPS core is 100% waterproof and still functions if it becomes damaged

abP* approved: wedi 610 seals joins between boards and makes them waterproof without the need to use any other products. As it is not necessary to use any other waterproofing materials, the tradesman benefits from increased security and a shorter application time

The cement-coated surface forms an incredibly strong base for adhesive thanks to the integrated fabric

All of wedi’s building board systems provide fantastic insulation, save energy costs and protect against mould for the long-term
