Joist Kits

Joist Kits require foil backed insulation fixed between joists. Pipe is then laid into heat diffusion plates which are nailed to the joists, then everything is covered by a structural deck. Each kit can be controlled by a single thermostat to operate independently from a radiator system with the inclusion of a zone valve.
We offer a range of Heatmiser™ Thermostats for seamless use with the Joist Kits.
