  • Provide uncoupling through the open rib structure, which allows for in-plane movement that effectively neutralizes the differential movement stresses between the substrate and the tile, thus eliminating the major cause of cracking and de-laminating of the tiled surface
  • In conjunction with tile coverings, forming an uncoupling, waterproofing, and vapor management layer, while providing support load distribution
  • The combination of these four essential functions allows for the successful installation of tile over a wide range of substrates, including plywood/OSB, concrete, gypsum, heated floors, etc
  • 5/16" - (7 mm) thick allows even transitions between tile and 3/4" thick hardwood flooring
  • For ceramic tile application over single-layer plywood/OSB subfloors on joists spaced up to 24" (610 mm) o.c

Common Questions

What is the difference between DITRA and DITRA-XL?

Schluter®-Ditra-XL provides the same four essential functions as Schluter-Ditra, uncoupling, waterproofing, vapor management and support/load distribution, but is ⁵/₁₆-inch-thick, whereas Ditra is ¹/₈-inch-thick.


What are some of the primary characteristics of Schluter DITRA XL

The square-shaped cavities on the underside of DITRA XL allow for even load distribution across the tile covering. This feature is particularly beneficial when installing large-format tiles and stone. DITRA XL also comes in larger roll sizes, which can make the installation process more efficient
