Using insulation beneath electric underfloor heating significantly improves efficiency, enabling the system to reach steady-state faster while reducing energy consumption. Proper insulation can deliver over 50% energy savings compared to uninsulated installations. Selecting the right insulation is crucial and depends on the system’s stratigraphy, particularly for glued floors.
These insulation panels are highly adaptable:
Can be glued directly to the subfloor
Allow direct installation of heating elements and final flooring (tiles, wood, etc.)
Water-resistant and simple to install
Honeycomb surface ensures strong adhesion to both subfloor and flooring
Constructed with two layers of fiber cement and a high-density XPS insulation core, these panels are:
Suitable for both walls and floors
Easy to cut (using a standard cutter)
Ideal for space-constrained applications
Available in 6mm, 10mm, 20mm, and 30mm thicknesses
