Building Panel Applications – The Ultimate Tile Backer Board
The wedi Building Panel is a high-performance tile backer board that works on its own or within a shower system. wedi Building
Panels have a blue core made from extruded polystyrene, high-load rigid foam. The foam core is formed by a closed cell matrix
making the wedi Building Panel internally waterproof, mold-proof, and insulating. Both sides of the wedi Building Panel are
covered with a specialized fiberglass mesh fully embedded in a cement resin coating that transfers fully through to the foam
core. The specific combination of mesh and coating adds high tile backing strength capability and controls moisture absorption
and spread on the surface, which is essential to maintain effective topical seals over assembly seams. The mesh reinforces
the wedi Building Panel and also provides a waffle pattern structure that thin-set mortar can lock into. At the same time, the
mesh and coating provide a flat and even surface ideal for tile. The high quality of raw materials, how they interact, and the
manufacturing process we have developed and automated over the last 40 years produces a premium tile backer board like no
other. The wedi Building Panel installation steps and techniques are shown in great detail within our shower system installation
manuals in this handbook. In addition, you can find more information about unique installations with wedi Building Panels on
www.wedicorp.com. We cover applications such as tub surrounds, general floors, floors with heating systems, countertops, and
kitchen backsplashes, or building custom seats and benches on our website.
