Marmox - Underfloor Heating

Introducing Marmox Multiboard underfloor heating insulation

Underfloor heating insulation boards are an important aspect of any underfloor heating system. They provide a suitable foundation on which to lay cables or pipes and they help to ensure that a room retains its heat effectively.

Underfloor heating has recently become a popular choice for heating homes. These systems provide a uniform heat distribution throughout rooms and are very comfortable for walking on with bare feet.

When installing an electric underfloor heating system, the Marmox Multiboard underfloor heating insulation is an ideal choice. With its excellent technical specifications and ease of installation, it not only simplifies setting up an underfloor heating system, it will also help to reduce your heating bills and cut your carbon footprint.

Why choose Marmox Multiboard underfloor heating insulation?

Marmox Multiboard is a fully waterproof insulation board with excellent load bearing strength of 40 tonnes per square metre and is very easy to handle when installing. Marmox Multiboard is unaffected by the freeze/thaw cycle, and being CFC-, HCFC- and asbestos-free, it is safe for use in any location.

When compared to plain polystyrene (which is unsuitable for underfloor heating) Marmox Multiboard out performs on all levels with its insulation products.

As well as underfloor heating insulation, Marmox Multiboard can also be used on walls and ceilings as a waterproofing and insulating surface. It is especially useful in locations where damp can be a problem like wetrooms.
