Underfloor Heating XPS Panel

Radical Lite XPS Underfloor Heating Insulation Boards

Radical Lite XPS Insulation Boards provide a lightweight, cost-effective and low-profile solution for underfloor heating installations. The range is available with or without a foil facing and includes options for 12mm or 16mm pipework, as well as systems designed for installation between joists.

Manufactured from extruded polystyrene insulation, the boards help direct heat upwards into the room while reducing heat loss through the subfloor. Their durable insulation performance is designed to remain effective throughout the life of the building.

The lightweight construction makes the boards easy to transport, cut and install without specialist equipment. They are suitable for a variety of floor constructions, including beneath screeds and chipboard, within heated slabs and below suspended slabs.
