A guide to “over the floor” Overlay™ Underfloor Heating systems

For existing solid or timber deck floors – Polypipe’s unique Overlay™ underfloor heating range of low profile systems are installed over the existing floor. This makes them ideal for renovation and new build, whole house and single room projects.

Overlay™ Plus

Introduced in January 2020, Polypipe’s new patented Overlay™ Plus underfloor heating panel is a low-profile system that has been designed to be installed over existing floors. It is the ideal product for new build and rennovation projects with a version also available to reduce tranmission of impact noise with an additional layer of synthetic rubber on the underside.

It has had some great feedback from installers so far thanks it’s larger panel size and light weight. Overlay Plus boards can be tiled directly onto and cut to size with a utility knife.

Below are some Overlay Plus installations that we have been tagged in since it’s launch. Click through to visit the original installers Instagram account.
