Warmboard–R is our 13/16” thick panel that provides the same superior radiant heat performance as our original 1-1/8” thick Warmboard-S panel. This slimmer profile and smaller panel size, is ideal for remodels and renovations where the full strength of 1-1/8” Warmboard-S is not required. It’s also an ideal solution for radiant cooling or where ceiling heating is desirable in order to preserve existing floor coverings.

Which Product is Right for Me?

Warmboard and Warmboard–R offer the same superior heating performance. Both products are made with the same thick aluminum that covers the entire panel surface, including all straight and curved channels where tubing is placed. Thermodynamically identical, both products provide the same benefits of comfort and energy efficiency. Generally, new construction and new additions will use Warmboard-S, benefitting from its dual function as a structural subfloor. Remodeled areas of a home will typically use Warmboard–R. Our staff is ready to guide you through this process should you have further questions.

How do Warmboard-S and Warmboard-R differ?

Warmboard-S is a structural radiant panel that is 1-1/8” thick, made of Douglas Fir 7 ply plywood, and is sold in full-faced tongue and groove 4’ x 8’ sheets. Warmboard–R is 13/16” thick, made of aspen and pine oriented strand board (OSB) and is sold in square edged 2’x 4’ panels. Both products have the same thick, highly conductive 1060 alloy aluminum, which is securely bonded to the entire surface. This 0.025” plate is continuous in all tubing grooves. The thinner nature of Warmboard–R makes it particularly well suited for projects where a lower profile is advantageous.

Does my purchase of Warmboard-R include design services?

Our in-house design team provides full panel, tubing and manifold shop drawings, for every project. This level of service, and excellent technical support, is included with the purchase of all Warmboard products.

We also offer, for a very reasonable fee, complete Heat Loss and Mechanical designs. These professionally engineered drawings specify and size all mechanical and electrical components needed for an elegantly simple and easy to install radiant heat system.
