The JG Speedfit Overfit® underfloor heating system is designed to be installed over existing floors and is considered a retrofit system suitable for new-build or renovations where a low profile system is required.
It is comprised of lightweight insulated panels which make it easy to transport, handle and cut. This combined with the high compressive strength of the boards make it suitable for larger areas and multiple room projects.
The system uses 15mm underfloor heating pipe and when complete can be covered with a wide range of floor coverings such as:
Tiles/slate/ceramic etc (use with Knauf Brio board or equivalent)
Carpet/vinyl (use with plywood covering)
Laminate floors (use directly over insulation)
Natural wood (fix to battens between panels
