Summary: Information on Underfloor Insulation
With more and more people using underfloor heating these days its really important to make sure your floor is insulated properly to allow the heat to come up rather than go down. At www.warmfloorsonline.com we are able to supply two types of underfloor insulation which, even though they have fantastic insulation qualities of their own, are exceptional value when used with underfloor heating.
WarmFloors supplies a revolutionary carbon under floor heating system that is so thin it hardly makes an impression on floor height, ideal for when every millimetre counts!
With wood and laminate flooring becoming evermore popular this under floor heating system is the perfect solution.
The under floor carbon offers an attractive alternative to other heat sources such as radiators, as it is hidden from view & can free up much needed wall space, giving you the freedom to design your room how you want.
The under floor carbon heating film which is installed directly below your wood or laminate flooring, provides a fast acting heat system which in most cases can replace radiators and other conventional forms of heating.
The under floor carbon heating's unique double laminated design means that the element itself is less than half a millimetre thick and yet is extremely durable and robust which is backed by a TEN YEAR GUARANTEE.
The under floor carbon heating system is made up of several components, such as the Depron insulation which would replace any normal wood/laminate underlay, the carbon elements themselves, then a moisture barrier and a digital thermostat.

Depron is a highly efficient extruded polystyrene insulation material suitable for use below wood, laminate or even carpets. It is available in 3mm or 6mm thicknesses, does not conduct heat and cannot be broken down. There is therefore no wasted heat. Depron also replaces the underlay required for laminate flooring.
INSULATING TILE OR SCREED FLOORS
For tiles or screeded floors a tile backer board can be used to give great insulation as well as provide a good key for the tiles. Tile backer boards are ideal for laying underfloor heating on also.
Marmox thermal tile backer boards are high performance, reinforced insulation boards made of waterproof extruded polystyrene, each side is faced with fibreglass mesh embedded into a cement polymer mortar. Marmox boards are the perfect solution for insulating and waterproofing in one operation & the boards are especially recommended for all underfloor heating systems.
The main benefit Marmox provides over standard polystyrene boards is the compressive strength of 30 tonnes per sqm. This means that the boards can be fixed on top of the existing sub-floor (concrete or timber). When used with electric underfloor heating cables, this means that the floor will heat up in a matter of minutes, not hours resulting in significant energy savings & greater user comfort.
The other big advantage is that due to the integral fibreglass mesh & cement coating mean that you can lay heating cables/mats directly onto the board & then tile directly over them without the need for a levelling screed.
The boards are available in various thicknesses between 6mm – 50mm making them ideal for both renovations & new floor construction (especially conservatories)
