Why Warmboard Provides Better
Radiant Heat:

Warmboard has the two most important properties for excellent thermodynamic performance and radiant heat output: high conductivity and low thermal mass.

About Us

Warmboard has been sold for over 8 years with thousands of installations. It was invented by Terry Alsberg, our CEO, who also holds a patent on Warmboard’s technology. Warmboard radiant subfloor systems bring homeowners the benefits of radiant heat while eliminating construction difficulties and costs associated with a traditional radiant installation.

Today, Warmboard is available throughout North America, and has recently shipped its product into Canada, Europe, the United Kingdom, Japan and Antarctica.

Here’s what our customers say:

“Each person has been extremely helpful”

I’ve conversed with individuals from every facet of their company – each person has been extremely helpful and informative … even though I was a novice on these issues when starting out. Over the three 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??

“Technical support was outstanding throughout our entire project.”

We are thrilled with the practicality and performance of the Warmboard system and the many options for floor coverings, including salvaged hardwood. During flooring installation, the ability to see the tubing was ideal. Warmboard’s technical support was outstanding throughout our entire project. They always had time to talk to us and answer any questions we had. We would recommend Warmboard to anyone!

“Thank you for your excellent service.”

This is just a short note to thank you for your excellent service. We were so happy to get our Warmboard order designed and delivered in one week! The instructions were easy to follow and my husband (and friends) had no trouble installing it in a couple of days. We really appreciate your help and follow-up, with the whole transaction.
