Building panel Construct

„The flexible building panel for freedom of design.“

Product information

wedi building panels have a blue core made from CFC-free extruded polystyrene rigid foam.
This makes the wedi building panel an ideal basis for any type of plaster and tile. wedi building panels can be applied to practically any substrate, are waterproof, insulating, versatile, light and robust.

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

  • The blue XPS core is 100% waterproof and remains fully functional even after possible damage.
  • The cemented surface is a good adhesive under-surface. The fibre fabric also absorbs tensile forces.
  • All building panel systems have great heat insulation properties,

All advantages at a single glance
