Uncoupling membranes or decoupling layers are designed to neutralise tensions between the flooring substrate and tiles. Sub floors can retain a large amount of water and are prone to expand and contract with humidity and temperature changes. The uncoupling membrane helps to prevent stress from this expansion and contraction from transferring through and cracking finished tiled surface. Some decoupling membranes, like the ones that Tile Fix Direct stock, can be also used with electric underfloor heating systems.
These membranes also alleviate stress that is caused by thermal movement. The air spaces under the membrane allow the residual moisture to escape, preventing cracks from forming in tile floors. Decoupling membranes also allow the heat from the underfloor heating system to be spread evenly across the floor surface. This increases the overall effectiveness of the heating system, reducing your heating costs. All the decoupling systems at Tile Fix Direct are suitable for use with electric underfloor heating.
As well as being waterproof, these uncoupling layers also have vapour management properties. They allow vapour to dissipate through formed channels on the underside of the membrane which prevents moisture build up in your floors and walls, preventing mould and damp growth. You can use these membranes to control moisture in substrates like plywood, plasterboard, cement mortar and more. They also have a lower profile than tile backer boards and even have sound reducing qualities to help stop impact noises spreading to rooms below.
Many of the uncoupling mats are a necessary addition to your tile installation to ensure the longevity of the project and improve the cost effectiveness of Underfloor Heating Systems. They are also highly resistant to chemicals usually found in wall and floor tile installations. We stock popular products like Ditra Matting, Durabase Matting, Rapid Mat and Flexbone Matting as well as Uncoupling Matting Adhesive. We only work with trusted brands like Schlüter, Dural, BAL, Kerakoll and Ardex to bring you solutions you can rely on time and time again.
