The UK's Most Reliable and Effective Decoupling Membranes

Decoupling membranesIncrease the durability and strength of your tiles and grouting in your UK bathroom with the exceptional quality decoupling membranes from Marmox.

Decoupling membranes are thin mats which protect tiles from damage, if the base moves from beneath them. Movement in the floor can cause cracks in tiles and grouting, therefore ruining the appearance of your wet room or bathroom. Having our Marmox decoupling membranes installed at your UK will therefore prevent this and as a result keep your tiles in exceptional condition. 

Ideal for a multitude of purposes, our specialist and economically friendly multiboard provides a lightweight tile backer board option, as well as a dry lining, waterproofing thermal insulation solution. 

In addition to being an effective shower and tile backer board, our multiboard boasts longevity and durability especially as a decoupling membrane, which prevents grout and tiles from cracking due to horizontal moment in the floor. The extraordinary patented surface of our multiboard allows heavier tiles to be securely and safely fixed to walls.  Being completely impermeable to water, it is doubly useful in areas prone to moisture, making it the perfect option for any UK homeowners and property owners searching for a bathroom or kitchen tile board.  

Use our Decoupling Membranes for a variety of purposes across the UK

Perfect for UK residences, our economically friendly and specialist multiboard can be used to waterproof and insulate walls, floors and ceilings and noticeable benefits will be gained by using any thicknesses of 10mm and above. The thinner 6mm and 4mm boards are mainly designed as waterproof tile backer board options, but these will also provide some thermal insulation. Even the thinnest boards will be useful when used with underfloor heating wire to reduce your heating costs.  Furthermore, the decoupling membranes help to keep heat from the underfloor heating system to be spread evenly across the surface and therefore improve the effectiveness of the heating system.  

Our multiboard is not just suitable as an insulation board or tile backer board option beneath plaster within a building. Because Marmox's specialist multiboard is certified for external use, it can also be used as an external tile backer board and can be used outside, beneath a coating of render.
