Over floor underfloor heating

Ideal for refurbishments

EPS panels, 1200mm x x1200mm, in any thickness from 18mm to 100mm. Combining insulation with underfloor heating – perfect when refurbishing older buildings.

The Profi-Panel system is used to add underfloor heating to existing floors - where it is possible to increase the floor height. It is more commonly used in older buildings with sufficient head and door height, to raise the floor level by between 18-100mm.

The advantage of this system is it combines insulation - often missing from older floors - with underfloor heating in one product.

Profi-Panels are supplied with foiled grooves, to aid in an even heat distribution.

Panels are available in the following thicknesses

  • 18mm (12mm pipe)

  • 20mm - 100mm in 5mm increments (using 16mm pipe)


The 1200 x 1200mm panels are laid onto an existing load bearing subfloor.

Curved ends should be placed along the shortest walls, giving maximum length of straight pipe runs. The centres are then installed, cutting panels as necessary.

The 16mm pipe then pushes into the groove, following the pipe layout drawing that is supplied for your rooms. Pipes are covered with foil tape (supplied) to stop dirt and dust before contamination before the floor is installed.

A vapour barrier (not supplied) should cover the floor, followed by either the finished floorcovering (eg floorboards, laminate, timber) or 9mm plywood prior to tiling, vinyl flooring or carpet.
