An underfloor system that provides even comfort throughout your floor without any additional buildup height.

What is joisted underfloor heating?

Joisted underfloor heating consists of lifting your floor boards, notching the joists beneath them and running warm water pipe through either Aluminium Spreader Plates or aluminium coated Rapid Response® EPS boards and relaying your floor boards. You can then run the floor heating at low temperature 55°C and enjoy the unparalleled comfort with out needing to add any build up height to your project.
