Can I use Kingspan Insulation with Underfloor Heating?

Yes, Kingspan floor insulation is suitable for use below underfloor heating systems.

In a typical dwelling, 100mm of the Kooltherm K3 floor insulation should be loose laid above the damp proof membrane with a strip of the same insulation (minimum 25 mm) placed vertically around the exposed perimeter of the floor slab to prevent cold bridging. A polythene sheet should then be placed above the insulation before installing the underfloor heating system and pouring the concrete screed.

More details on how to install Kooltherm K3 alongside underfloor heating are available if you would like to discuss your project with our technical support team please complete the enquiry form below.
