Retrofit onto Existing Floors

Underfloor Heating for Retrofit onto Existing Floors

Many of our customers require an underfloor heating solution that will fit over an existing floor to minimise disruption, or if excavation is not possible. Our systems cover these applications perfectly, too, with our Overlay™ system that’s specifically designed to be fitted, quickly and easily over an existing floor - with slim polybutylene pipes raising height by as little as 12mm to retain maximum room height.
