wedi building board XL & XXLLarge building boards, ideal for partition walls
wedi building boards XL and XXL
„Stand-alone, robust wall solution with
only one single wedi building board.“
Product information
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, they are waterproof, insulating, versatile, light and robust.
These large building boards stand out because of their distinctive width, of up to 1.20 m. This means that the XL and XXL building boards are easy assembly with all the benefits of the classic wedi building board such as being light and easy to handle, despite their size. Simple to assemble and big in quality.
- The blue XPS core is 100% waterproof and remains fully functional even after possible damage.
- abP*: building board butt joints can be 100% sealed, simply by using wedi 610. Because no other seal is required, craftsmen will benefit from increased security and 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,
All advantages at a single glance
only one single wedi building board.“
