WBI The Radiant Panel Company®
Founded in 2000, WBI has been manufacturing a variety of radiant heating solutions including Ecowarm® RadiantBoard® and ThermalBoard™. Our patented radiant panel systems provide excellent performance and efficiency. Installation is fast and easy with our paint-by-number CAD layout designs, saving time, labor and money. We provide the broadest offering of radiant panel solutions in the industry. The company has additional patents and patents pending.
Aluminum Surfaces
All WBI radiant panels are laminated with highly conductive aluminum that provides vastly improved heating response time over cementitious or plain wood panels, while permitting the use of lower water temperatures and the resulting higher efficiencies.
Modular Installation
All WBI radiant panels are designed and produced in small panels that are easy to install.
Panel Layout Services
All WBI panel systems are offered with panel layout design services.
Factory Direct
All WBI panels are sold factory direct to the jobsite.
About Warm Brothers Inc. (WBI)
Warm Brothers Inc. (WBI) has been manufacturing nonstructural radiant floor heating systems under U.S. Patent #6,533,185 for more than 20 years. During that time, we have produced and supplied millions of square feet of radiant panels to residential and light commercial projects across North America. Our products have been sold under several trusted brand names and are known for consistent performance, practical installation, and long-term reliability.
WBI operates with a factory-direct mindset and currently supports customers through two manufacturing and distribution locations, one in Washington State and one in Wisconsin. This dual-location approach allows us to efficiently serve projects nationwide while maintaining tight quality control and dependable delivery timelines.
From a 1987 start to nationwide manufacturing and distribution
Warm Brothers Inc. has served customers across North America since 2000. Built on radiant-heating experience dating to 1987, WBI has continued to develop practical radiant-panel solutions while expanding its manufacturing and distribution capabilities from Oregon to Wisconsin.
