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

Product Sizes
To determine the size and quantity of wedi Building Panels you will need for your shower, please follow the steps outlined below:
First, you must calculate the total area of the shower walls. To do this, measure the area of each shower wall by multiplying the length of the wall by the height. The height of each wall will be determined based on how high you plan to install the tile. Next, add the calculated square footage of each wall together to determine the combined sum of all the shower walls. Account for about 15% extra square feet of building panel for any waste cuts by multiplying the combined area of all shower walls by 1.15.
Next, divide the total area of the shower walls by the square foot area of the wedi building panels you plan to use (eg: 4×5 ft. building panel = 20 square feet). A total shower wall area of 115 square feet divided by 20 square feet per building panel gives us a total of 5.75 building panels. Remember to always round up to the next whole building panel.
