HeatDeck is a high performance underfloor heating board. Manufactured from reinforced gypsum, the CNC routed panels are engineered to provide optimum underfloor heating conditions in new build and refurbishment developments.

These boards are 100% dry system that is able to accept floor finishes (carpets, wood floors, ceramic tiles etc) within 24 hours of installation. A significant time saving benefit over wet system alternatives. The underfloor heating pipes are laid inside the panels routing pattern. The highly conductive boards transfer the heat from the underfloor heating pipes quickly, efficiently and effectively underfoot and into the surrounding room.

NOTE: These are straight edge boards – bond together with gypsum board adhesive.
