Schluter - DITRA and DITRA XL sold by the roll

Schluter - Ditra is an uncoupling and waterproofing membrane that is recommended for any even and load-bearing substrate such as: plywood and OSB; 24" o.c. truss and I-joist systems; green concrete; gypsum-based screeds; pre-stressed and post-tensioned concrete; and radiant-heated floors. For most tile installations, Schluter - DITRA eliminates the need for a second layer of plywood or for the use of cementitious backerboard. Schluter - DITRA ensures a lasting installation by allowing independent movement between the tile covering and the substrate. This eliminates the transfer of stresses from the substrate to the tile covering. In addition, Schluter -DITRA is lighter, thinner, and easier to apply than any other underlayment.
