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.

 wedi offers one comprehensive warranty versus multiple manufacturer and labor warranties

 wedi dramatically reduces installation and labor time, curing times, and overall physical effort and mess
