Imperial Decoupling Membrane 3mm 20M Anti Crack Waterproof Uncoupling Tile Mat Underfloor Heating Vapour Barrier Ditra Sound Proof Ceramic from B&Q

Imperial

Protect your tiled floors from cracking, movement and moisture damage with this professional grade 3mm Decoupling Membrane — the essential undertile installation layer trusted by professional tilers and DIY enthusiasts across the UK for ceramic, stone and all standard floor tile installations.This 3 layer polyethylene composite decoupling membrane is specifically engineered to prevent the transmission of lateral stresses and substrate movement to the finished tiled surface — eliminating the cracking, grouting failure and tile debonding commonly seen when tiling over problematic substrates such as heated screeds, timber floors, OSB, plywood and tongue and groove floorboards that are subject to natural movement.The membrane channels provide even heat distribution throughout the floor when used in combination with wet or electric underfloor heating systems — eliminating hot and cold spots and ensuring your underfloor heating performs at maximum efficiency without raising the sub-floor level significantly.Fully waterproof — the polyethylene composite construction protects the substrate from water infiltration preventing damp damage to timber floors and structural substrates below the tile. The integrated vapour barrier provides additional moisture protection whilst the acoustic properties reduce impact sound transmission through the tiled floor.Simply roll out the membrane, secure it to the substrate and apply your tile adhesive directly to the membrane surface. Compatible with all standard tile adhesives and suitable for use under ceramic, porcelain, stone and all standard floor tiles on concrete, timber, OSB and heated screed substrates.Supplied as a 20 metre roll at 1 metre width — covering 20 square meters per roll — ideal for larger tiling projects trade use or multiple room installations.
