Warmup Dual Overlay System

The Warmup Dual Overlay System is recommended for use with Warmup’s Foil Heater and Insulated Underlay, allowing for a complete electric underfloor heating solution. Additionally, the two layers of the Dual Overlay system sit above the foil heater, and acts as a strong and stable subfloor, protecting the floor heater from heavy objects such as wardrobes or beds. In Fact, this whole system is free-floating and easy to install!

The Warmup Dual Overlay System is composed of two separate top and base boards. Because of this, they are laid in a way to stagger and overlap the joints creating a strong subfloor. Also, since the Dual Overlay system is not fixed to the floor below, it offers a quick and clean installation without the need for screed! Once these boards are bonded together, they have a thin final depth of only 7mm!

Please note some floor manufactures only allow the use of underfloor heating systems when they are embedded within a screed/levelling compound. Furthermore, it is important that you contact the tile manufacturer to check that the Warmup Dual Overlay System is suitable!

These deliveries take place on large 18-tonne trucks with tail lift capabilities and are strictly kerbside deliveries. If your property has restrictive access please let us know in the comments box at checkout.

Obstructions e.g. steps, lifts, gravel paths and drives etc may mean the delivery will have to be made to the nearest available location to the delivery vehicle.
