Why choose wedi?

The wedi Building Board is made of highest quality ingredients: the closed cell, rigid XPS foam core for consistent waterproofing properties. The strong fiberglass reinforcing mesh on both sides and fully embedded in the boards coating for strength. And finally, the proprietary wedi resin coating on cement basis for a great bond to tile and stone adhesives of all types. wedi Building Boards are made from materials which do not support the growth of mold or mildew, making the board a great underlayment and protection system when used in wet areas such as showers.

Working with the wedi Building Board is clean and easy. Cutting the boards can be done with just a utility knife. You may cut through the entire board or score and snap. Insulation properties of the XPS foam core come in handy where a heat break is needed such as when using the wedi Building Board as an underlayment under floor warming systems. All wedi Building Boards are extremely lightweight and easy to carry and handle on site.

All wedi Building Boards are made free of HCFCs or other ingredients which may expose users to dangers during and after installation.

The variety of wedi Building Boards goes back to the broad range of application possibilities: 1/8 inch boards are used to create kitchen back-splashes or over tub decks, 1/4 inch boards are mostly used on floors, 1/2 inch and 5/8 inch boards are designed for use over framed walls and ceilings. 2 inch boards will make ideal base material to construct shower seats or kitchen countertops from- without the need of any support framing.

But this is not where wedi stops in its continuous efforts to adding value for wedi users. Part of using wedi systems also means to enjoy a systematically developed service offering which will help you completing your projects professionally: a comprehensive and well equipped warranty up to 20 years, certification programs for wedi installers, our field assistance service who will be by your side whenever there is an installation question- hands-on.

But wedi is not only a Building Board and tile underlayment that works great in so many settings. wedi is a shower and wetroom system, the Building Board is one integral component of it. Shower bases, sealants, fasteners, other components such as seats, curb s or soap niches complete the wedi modular system solution.
