Warmup Underlay

Warmup Underlay is an insulated barrier that is made from very thin polystyrene. It is designed to be used with the Warmup Foil Underfloor Heating System, and it is positioned between the subfloor and the foil heater.

Once in place, it reduces heat loss from the foil heater by preventing the heat from going down into the ground and reflects heat upwards to ensure more heat goes into the room. In addition, it provides extra cushioning from steps and lessens the impact, helping to protect the system.

The result is a more energy-efficient underfloor heating system that reduces heat loss, heats the room faster and saves you money on your energy bills.
