Today’s construction methods, which include the use of lightweight materials, have made the installation of hard surface
coverings particularly challenging. Because of the differences in material properties, the substrate and the tile layer expand
and contract at different rates, creating stresses in the assembly that can ultimately result in damage to the finished tile
surface.

-DITRA and DITRA-XL address the problems associated with today’s fast, lightweight construction methods,
allowing the installation of ceramic and stone tiles on virtually any surface.
Uncoupling Membranes
DITRA & DITRA-XL
are polyethylene uncoupling membranes with a grid structure of square
cutback cavities and an anchoring fleece laminated to the underside. DITRA
and DITRA-XL provide uncoupling through the open rib structure. This 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 delaminating of the tiled surface.
Notes:
•
DITRA is 1/8" (3 mm) thick
•
DITRA-XL is 5/16" (7 mm) thick
•
DITRA and DITRA-XL are listed by cUPC®
•
DITRA and DITRA-XL have been found to found to comply with the VOC
requirements of California Specification 01350
•
CA 01350 is referenced by various green building standards and rating systems
