Radiant Heat Panels

Warmboard has been the leader in radiant subfloor panels for home heating over 25 years, using the highest quality wood products and thick, pure aluminum.

Warmboard industry-leading hydronic radiant floor heat panels are bonded to thick, 1070 aluminum alloy which covers every square inch of the panel surface, including all tubing channels. This highly conductive surface ensures heat is spread quickly and evenly throughout the home, providing faster response times and lower energy usage than any other system. Tubing channels are spaced every 12 inches and hold ½” PEX tubing. You can use any type of flooring you wish over our Warmboard panels, and only Warmboard has letters of recommendations and warranty letters from both tile and hardwood companies.

Every Warmboard project includes easy-to-follow, color-coded plans to guide the installation. Ready to start your project? Submit your floor plans.

Warmboard-S™

Warmboard-S is a 1⅛” thick tongue and groove structural subfloor panel. Panels measure 4’ x 8’ and are made from 7-ply Douglas Fir. Warmboard-S typically installs directly over joist (16” spacing is ideal) or concrete by a standard framing crew. Panels can be cut, glued and nailed just like traditional subfloor. Warmboard-S panels are very durable and can endure the rigors of a jobsite. Warmboard-S is rated Exposure 1 by the APA.

Benefits of Warmboard-S
