Warmboard combines a structural subfloor and a thermodynamically sophisticated radiant panel into an elegantly simple system.

As a subfloor, Warmboard is installed and the tubing laid before other construction takes place, eliminating the need to design the system around interior walls.  Warmboard begins with a stiff, strong, 1-1/8" thick, 4' X 8' sheet of tongue and groove, weather-resistant plywood.

A modular pattern of channels is cut into the top surface of the board and a thick sheet of aluminum is stamped and permanently bonded in place to match the channel pattern.  With this design, Warmboard provides a versatile and very effective system for any new construction.
