wedi building board and its strongly underestimated property
The wedi building board is not only waterproof, the ideal base for plasters and tiles, but also thermally insulating. Depending on the outer wall, heat loss can be reduced by about half with a wedi building board with a thickness of 20 mm.
Thermal conductivity: 0,036 W/mK
wedi Preline:
Carrier Element for Warm Water Heating Systems
Wedi PreLine is a fully prepared construction panel element that comes with factory-integrated cutouts for the easy installation of a warm water heating system. Its robust insulating properties reflect heat back into the room, ensuring an even distribution of warmth.
One of the standout features of wedi PreLine is its ability to minimise the construction height of the floor build-up to a minimum of just 30 mm. This is particularly beneficial in projects where maintaining a low profile is essential, such as in renovations or smaller spaces.
Additionally, when used in conjunction with the appropriate wedi system accessories, wedi PreLine also serves as a waterproofing solution. This dual functionality not only simplifies the installation process but also enhances the overall efficiency of the heating system.

How it works

Mount the wedi PreLine on the surface with the ARDEX X 90 flex adhesive, glue the joints with wedi 610 adhesive and sealant.

Laying of commercially available water pipes Ø16 mm and filling with ARDEX X 90 flex adhesive.

To the adjacent areas, seal with the ARDEX S 7 Plus and ARDEX SK 12 TRICOM flexible sealing slurries and reinforce the entire area.

Then use ARDEX X 90 Flex Adhesive Tiles and ARDEX G 10 Premium Flex Joint Mortar.
