Floor Building Panels

Product information

Whether it is in new construction or renovation, a great variety of subfloor types need a tile underlayment prior to setting tile or stone. Some of the reasons for the need to install tile underlayments include: they may reduce stresses from subfloors and protect tile; they may be used to build up height as needed to finish the tile surface flush with adjacent flooring surface; and they may be necessary for waterproofing or insulation purposes. Also very important, they should provide and support successful and lasting adhesion performance for thinset mortar and tile.

wedi Building Panels offer a durable underlayment surface once tiled and it passes the Robinson Floor Test (ASTM C627) having achieved a “heavy duty use“ rating. In combination with its ideal flat surface, it is a logical choice when installing either small tile or very large tile but possibly extremely thin tile on floors. Both require perfect thinset mortar coverage and adhesion, made easy when working on a most flat and even surfaces and they need the full support of a strong underlayment like the wedi Building Panel. It is, however, important to evaluate the suitability of a subfloor structure, or the layer below a tile underlayment, to ensure a proper tile installation and also the choice of a good underlayment fitting the application.

wedi building panels are:

  • Used in wet rooms or where floor warming systems are used
  • Ready for tiling upon installation
  • 100% waterproof due to its extruded polystyrene (closed cell) foam core
  • Easy and clean to cut to size using a utility knife, circular saw or handsaw
  • Available in sizes and thicknesses that can accommodate different projects and applications
