Floating Floor Underfloor Heating Diagram

Solid Floor Underfloor Heating Diagram

The Polypipe floating floor system is designed for use in applications where a solid floor installation is not suitable due to structural weight limitations or where a ‘dry build’ floor option is required.

Floating Floor Underfloor Heating Description


Suitable for use in either new build or existing properties, the floating floor panels can be installed directly on top of both solid and timber floors.

The 50mm thick high density polystyrene panels have a thermal value of 0.036W/mK and can be used to enhance the thermal insulation requirement of the floor structure as required under current Building Regulations. However, care should be taken when installing floating floor panels on top of a primary insulation layer to ensure that excessive deflection does not occur in the final floor construction.

It is therefore recommended that any other insulation materials used below the floating floor panels are of a high density construction (100kN/m2 @ 10% compression min).
