About Us

Warmboard was invented in 1992 by architect and entrepreneur Terry Alsberg. He first became familiar with radiant heat when several of his clients began asking for it to be incorporated into their residential projects. Motivated in part by having two children with asthma, and unsatisfied with existing radiant options, Terry, using his background in architecture and engineering physics, worked out of his garage in Capitola, California to invent Warmboard. He filed a patent on the technology in 1994 and licensed that patent to Jeld-Wen in 1996. Warmboard Inc. was spun out as an independent entity in 2002 with Terry as CEO.

Over the past decade, Warmboard has become one of the most sought after radiant heating systems on the market, providing superior performance, substantial energy savings and unrivaled comfort. The patented design of Warmboard also makes it far more efficient for architects to specify and for builders to install. With over 27.5 million square feet of Warmboard installed throughout the world, from the Arctic to the Antarctic, homeowners on every continent enjoy the luxurious comfort of Warmboard radiant heat.

Warmboard is the preferred method of radiant heat by architects, builders, homeowners, flooring professionals and radiant installers. Our products have received numerous 'Green Product of the Year' awards since the company began operations.

The original Warmboard-S panel is a code-approved structural subfloor and radiant panel in one. Each panel is a 1 1/8" thick 7ply douglas fir plywood measuring 4'x8' - the same dimensions as standard subfloor. Each panel has is bonded to a thick aluminum plate, which is molded into the tubing channels - maximizing heat transfer from the water in the tube to the surface of the floor. There are 4 panel types to accomodate any design requirements.

In 2011, Warmboard, Inc released Warmboard-R, a smaller, thinner panel designed specifically for remodels. Warmboard-R is 13/16" thick and made from the highest quality OSB. These panels are also an ideal solution for radiant ceiling and wall installations.

Both products offer the same superior conductivity which allows our clients to easily heat their home in minutes/hours compared to the hours/days of other radiant systems.

Each project includes a full set of color-coded custom documents showing the placement of each panel, manifolds, tubing lengths and more. These plans can be bound with construction documents and provide all the necessary information to bid and install and job.

Our company is also known for its amazing customer service and supportive staff. We are always willing to take an extra phone call or email to answer a question about your project or about Warmboard and radiant heat in general. We're here to help.
