Heat loss through the floor is one of the most typical ways for the heat to escape making floor insulation especially important when installing underfloor heating. Heat loss can be expensive as it wastes energy and means that you have to have the system on for a longer period of time for the floor to heat up. By properly insulating your floor before installing underfloor heating, you can fully enjoy the energy efficiency benefits of using a system that heats up fast and distributes the heat evenly.

Insulation Promotes Efficiency

Insulating the floor ensures that an underfloor heating system will perform to its maximum efficiency. It will also prevent air draughts between the floor boards helping to trap the heat in your home.

The level of insulation needed in your home depends on the current levels of insulation. Recently built properties often have insulation within the ground floor, but older properties may not have this, so it’s worth checking the level of insulation of your home to ensure an efficient operation of the system. The type of underfloor insulation needed in your project depends on the system and heater type.

Adding floor insulation also means that your underfloor heating system will heat up quicker, using less energy as the system needs to be on at full power for a shorter period of time. The decreased energy usage will translate directly to your heating bill, saving you money.

Underfloor Heating Insulation Boards

Made from extruded polystyrene, faced on both sides with a fibreglass mesh embedded into a thin cement polymer mortar, Warmup insulation boards provide a high thermal barrier to cold rising from the subfloor when using the Warmup Stickymat or Loose Wire system. Available in different thickness, this type of floor insulation allows you to choose the suitable level – as a general rule of thumb the more insulation, the more efficient the system will operate, but the level you need will depend on the overall heat loss of your home.

The boards are easy to install and can also be used to insulate walls without adding to the thickness of the wall significantly. They also have soundproofing properties meaning you can soundproof and insulate your home in a single step by installing the insulation boards.

Insulated Underlay

Designed specifically for use with Warmup Foil Heater, the Insulated Underlay helps to reflect heat upwards, making the system more efficient. It sits between the cold subfloor and Warmup Foil Heater and it also acts as a moisture barrier and reduces contact noise.
