Schluter DITRA-XL Uncoupling & Waterproofing Membrane

Polyethylene uncoupling membranes with a grid structure of square cutback cavities and an anchoring fleece laminated to the underside.

Ditra XL Uncoupling Membrane Features:

  • 3 ft. 3" x 53' 3" = 175 sq ft. (1 m x 16.25 m = 16.25 m²)
  • 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.
  • DITRA allows for ceramic tile application over single-layer plywood or OSB subfloors on joists spaced up to 19.2" (488 mm).
