When installing onto wooden floors we recommend using insulation fixing washers & screws. Screws and washers must be fixed at minimum 300mm center's. This is approx 15 fixing per boards. Dimensional Stability: The boards are waterproof and exhibit excellent dimensional stability, maintaining their integrity and performance even in wet room environments. CO2-foamed, extruded polystyrene rigid foam with closed cell structure and flame-retardant additive. The polystyrene rigid foam is HCFC and CFC-free. FIXING INSTRUCTIONS - Boards should be stored dry and flat. Slight bowing caused by incorrect storage is not permanent and does not represent a technical defect. Slight curving can be rectified through storing the boards flat.

Use wedi Sealing Tape, Corners & Sealing Gaskets along with wedi 520 Waterproofing Membrane and wedi 610 Adhesive to seal joints between boards, internal and external corner junctions and around protruding pipes. The glass fibre reinforced coating creates a smooth, extremely durable surface that is ideally suited for the application of tile adhesives and other mortars. This eliminates the common causes of tile failure that are associated with panels made from MDF, chipboard, plywood, plaster and plasterboard. And unlike conventional wood-based boards, these panels are suitable for exterior use. Good insulation - reducing condensation -makes it a great surface to fit one of our electric underfloor heatingsystems onto & non-conductive surface reduces condensation by masking any cold bridging from the substrate beneath. Excellent Sound Insulation: The boards effectively reduce impact sound, creating a quieter and more comfortable environment.Outstanding Heat Insulation: With their excellent thermal conductivity value of 0.033 W/mK, these insulation boards significantly enhance the efficiency of underfloor heating systems. They reduce heat-up time and minimize running costs, delivering optimal comfort and energy savings. wedi Construct Building Board has pre-cut grooves either lengthwise or width-wise in the board to allow you to create curved walls and other interior features. Fibreglass Mesh & Cementitious Coating Offers higher adhesion to tiles than either timber or plasterboard

wedi Sanwell Niches are prefabricated wall niches used to create tiled storage shelves/areas in bathrooms and wet rooms, for storing bath and shower utensils. They provide a factory-made, watertight element that can be easily installed and saves a lot of time compared to constructing the element by hand.
