Schluter DITRA XL – Underfloor Uncoupling Membranes for Tile Installation

3′ 3″ x 53′ 3″ = 175 SqFt

Effective Uncoupling and Stress Neutralization

Schluter DITRA are polyethylene uncoupling membranes with a grid structure of square cutback cavities and an anchoring fleece laminated to the underside. The open rib structure of DITRA allows for in-plane movement, effectively neutralizing the differential movement stresses between the substrate and the tile. This eliminates the major cause of cracking and delaminating of the tiled surface, ensuring a durable and long-lasting tile installation.

Versatile Functions for Tile Installations

In conjunction with tile coverings, DITRA forms an uncoupling, waterproofing, and vapor management layer, while providing support and load distribution. This combination of essential functions enables successful tile installations over a wide range of substrates, including plywood/OSB, concrete, gypsum, and heated floors. DITRA-XL, with a thickness of 5/16″ (7 mm), allows for even transitions between tile and 3/4″-thick hardwood flooring. It also permits ceramic tile application over single-layer plywood/OSB subfloors on joists spaced up to 24″ (610 mm) o.c.
