Why Warmboard

Simply put – it's the best radiant heating system around

Conductivity is the heart of any radiant system

Why is Warmboard is a giant leap forward in the evolution of radiant heating. Because every aspect of the design and manufacturing of Warmboard has been implemented to maximize conductivity. Our patented design is the industry-leading low mass, high conductivity radiant heating panel. High conductivity means lower water temperatures, decreasing energy use, lowering monthly bills and extending the life of your mechanical equipment. Lower water temperatures also allow Warmboard to seamlessly integrate with solar and geothermal energy systems without the need for additional hardware. Our conductivity means faster response, heating your home in minutes, not hours (or days), ensuring constant comfort. It also means even floor temperatures and access to a wider variety of flooring options, from thick carpets to ornate hardwoods.

We offer two products. Warmboard-S is a structural subfloor and radiant panel in one. It is most commonly used in new construction, and is regularly installed directly over joist. Warmboard-R is a smaller, thinner panel ideal for remodels and retrofits. Warmboard-R typically installs over existing subfloor or slab, but is also used in the walls or ceilings when the original floors should remain intact.

When working with Warmboard, we walk you through the entire process with our one-on-one customer support. Every order includes scale drawings with panel and tubing layouts, manifold locations and the necessary technical information. Combined with installation manuals and devoted technical support, we ensure every project goes smoothly. With over 30 million square feet sold from Alaska to Antarctica, California to New York, know that you’re in good hands.

{…Over the 3 years of designing my project and enduring construction delays (for various reasons), I've sent them a ton of questions and phone messages. They have followed up on every single one, even providing technical information and explanations. Every individual seems passionate, and ethical, about the product…where do you find that today??
