Building board Construct

„The flexible building board for freedom of design.“

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, are waterproof, insulating, versatile, light and robust.

wedi Construct building board, offers many possibilities when it comes to designing customised forms. Whether you are looking for small radii or semicircular solutions, thanks to the pre-cut profiles the Construct building board gives you the freedom to be creative.

  • 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,
