Schluter DITRA-XL Membrane de désolidarisation 3'3" x 53'3" - 5/16" (7 mm) (175 pi²)

Regular price: $439.19

Description

Schluter-DITRA is a polyethylene membrane featuring a grid of square cavities, each formed with a dovetail, and a non-woven anchoring veil fixed to the underside. This veil is embedded in the thin-set mortar to ensure a mechanical bond with the substrate, while the setting mortar anchors into the cut cavities of the mat during a thin-bed installation. Designed for ceramic tiles and natural stone, DITRA acts as an uncoupling layer, waterproofing membrane and vapour management layer by absorbing moisture beneath the covering, while providing suitable support and load distribution. This allows reliable installations over many substrates — plywood/OSB, concrete, gypsum, heated floors, etc. — and with its 3.5 mm thickness it reduces the total assembly thickness and level differences with adjacent coverings (carpet, engineered wood, vinyl). DITRA allows tile installation over single-layer plywood or OSB subfloors on joists spaced up to 19.2" (488 mm) on centre. Uncoupling: DITRA's open-rib structure creates a slip plane that compensates for differential movement between the substrate and the tile. This principle neutralizes stresses that typically cause cracks and delamination of the tiled surface. Waterproofing: the polyethylene composition provides a reliable moisture barrier in interior applications, protecting substrates that are often sensitive to water in modern construction. Vapour management: channels under the mat form a free space that allows moisture and vapour from the substrate to escape, thereby reducing the risk of damage to the tile covering. Support and load distribution: during installation, columns of mortar form in the mat cavities and transfer tile loads to the substrate. The mat remains virtually incompressible within the assembly, enabling the benefits of uncoupling without compromising point-load distribution. DITRA's support and load-distribution performance have been validated by laboratory and field tests, including vehicle-traffic applications.

Technical information

Provides uncoupling, waterproofing, vapor management and distribution of heavy loads to preserve the durability and integrity of tile coverings.
Quick and easy to install over concrete, plywood, OSB, gypsum, existing vinyl floors, structural planks, subfloors and radiant-heated floors.
A practical alternative to cement backer boards or plywood for tile installations.
DITRA (standard): 3.5 mm thickness — allows the thinnest possible assembly while retaining performance; suitable for plywood or OSB subfloors over joists spaced up to 19.2" o.c.
DITRA‑XL: 5/16 in (7 mm) thickness — designed for plywood or OSB subfloors over joists up to 24" o.c.; creates a uniform transition between tile (≈5/16 in / 7 mm) and hardwood floors (3/4 in / 19 mm).
Ideal where increased movement tolerance is required — for example for natural stone and large-format tiles.
Designed for ease of installation: cut grooves for precise cuts and vents at cavity corners for faster filling.
