Product information
wedi building board systems
wedi building boards have a blue core made from CFC-free extruded polystyrene rigid foam. This makes the wedi building board an ideal basis for any type of plaster and tile. wedi building boards can be applied to practically any substrate, are waterproof, insulating, versatile, light and robust.
- The blue XPS core is 100% waterproof and remains fully functional even after possible damage.
- abP*: building board butt joints can be sealed 100% simply by using wedi 610. As no other seal is necessary, craftsmen benefit from increased security accompanied by a shorter tiling time.
- The cemented surface is a good adhesive under-surface. The fibre fabric also absorbs tensile forces.
- All building board systems have great heat insulation properties,

Usage
- The possibilities are endless when it comes to wall, floor not least because of the wide range of different thicknesses.
- They can be applied to practically any type of substrate. Whether it's old tile coverings, adhesive or non-adhesive substrate, lush mounting onto existing plasterboard or dry lining. Thanks to the simplified processing, wedi building boards can handle all manner of challenges on the building site.
