Product details
Custom Building Products uncoupling & underfloor heating membranes — warms the floor from below for comfort you can feel underfoot.
Both a waterproof and vaporproof uncoupling membrane that can be used for crack-isolation in most tile, porcelain, or natural stone installations. It can also be applied over challenging substrates such as installation over green (young) concrete and single ply 19.2″ (49 cm) o.c. wood framed floors. When exposed to excessive substrate movement, it absorbs stress and preserves the surface and integrity of the tile.
