Schluter uncoupling membranes provide the four essential functions for successful tile installation over a wide range of substrates, including plywood/OSB, concrete, gypsum, heated floors, etc. The choice between using DITRA or DITRA-XL depends on the nature of the particular project or application. The following points will help differentiate between the two products.
• Minimizes tile assembly thickness and reduces transitions to lower surface coverings (e.g., carpet, engineered wood, and vinyl)
• Only 1/8" (3 mm)-thick – provides the thinnest possible assembly without sacrificing performance
• Allows for ceramic tile application over single layer plywood/OSB subfloors on joists spaced at 24" (610 mm) o.c.
• 5/16" (7 mm)-thick – creates an even transition between typical 5/16" (7 mm)-thick tile and 3/4" (19 mm)-thick hardwood flooring
