Polypipe’s patented OverlayTM Plus is available from TDL Online. The underfloor heating board is a low-profile system that has been designed to be installed over existing floors. Making it the ideal product for renovation and new build projects. The new OverlayTM Plus  accommodates all types of floor coverings whilst remaining lightweight rigid and easy to install. The panels are formed of extruded polystyrene giving them their lightweight feature while also providing additional properties such as; thermal insulation, decoupling and waterproofing. The panel features two thin layers of fibre-reinforced polymer concrete with a polyester fleece-coated layer on top of an reflective aluminium foil. The aluminium layer is designed to evenly diffuse the heat from the pipes over the surface of the board. A version to reduce transmission of impact noise is available with a layer of synthetic rubber on the bottom side

The major component of the Overlay Plus Panel is rigid extruded polystyrene foam of a closed cellular structure. The core provides the following properties: Thermal Insulation, Decoupling and Waterproofing
The core is between two thin layers of fibre-reinforced polymer concrete with a polyester fleece-coated layer of aluminium on the top. The aluminium layer provides the following property: Dispersion of heat from the pipes over the surface of the board.
A version to reduce transmission of impact noise is available with a layer of synthetic rubber on the bottom side. 12mm diameter groves are cut into the board’s top surface to house the heating pipes.
