Warmboard-R is our radiant floor heating panel designed specifically for retrofits and remodels. It is a 13/16” thick radiant panel that provides unmatched response, energy efficiency and comfort. Warmboard-R panels measure 2’x4’, and are ideal for installing over existing subfloor or slab. They are also used regularly in wall and ceiling installations. As the retrofit hydronic radiant floor heating panels are installed, the modular channel pattern automatically produces the tubing layout, a process that takes much more time with other radiant systems. Roll out the ½” PEX (Aluminum PEX) tubing into the stamped pattern and attach to the hydronic circuit. This smooth process saves you money throughout your construction process.
The entire panel, including the tubing channel, is bonded to thick aluminum, creating a highly conductive surface which pulls the heat from the tube rapidly and spreads evenly throughout your home. Warmboard-R delivers a sturdier floor for your clients as well, and virtually any type of flooring can be installed over these retrofit floor heating panels.

Our design team will work with you (or architect or builder) to design the optimal retrofit hydronic floor heating panel layout for your project, including your zone preferences. Color-coded plans are provided showing where each panel installs, and includes tubing layouts and manifold locations well. When retrofitting underfloor heating, each project includes tools to ensure a smooth installation, including alignment pins and router templates. While installation is generally done by professionals, many DIY’ers have successfully installed their own Warmboard-R panels, and then hire a plumber for other parts of the project.

Warmboard-S 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.
