About Us
Pioneers of the steel structural insulated panel.
ThermaSteel panels are a four-in-one solution for the building industry. Our steel SIP panels perform structural framing, insulation, sheathing and vapor barrier, reducing labor cost and installation time by more than half. Our unique technology provides panels with a thermal break between the interior and the exterior of the wall, like no other SIP, making their energy efficiency even higher.
ThermaSteel began manufacturing panels in Radford, Virginia in 1970. What makes us a world leader in the panel industry? Not only did we pioneer the technology, but we also have extensive experience — over 75,000 projects around the world — and we can do the entire building envelope, or as much of the building as you want us to do. We have panels for exterior and interior walls, floors, concrete floors, roofs, shear walls and even foundation panels.
We manufacture commercial buildings, residential, tiny homes, tool sheds, freezers, net-zero buildings and passive nursing homes. We manufacture buildings for the military in multiple countries, in addition to aerospace, naval and other industrial applications. Nearly all our projects are custom designed for the specific desired application.
If you can sketch it — we can make it.
Over the last 50+ years we have developed 25 patents that allow us to design and shape the structure that you need. Our panels are high R-value (up to R-61), compliant with ASHRAE 90.1, and all are thermally broken. With a tight tongue-and-groove connection system, we exceed the requirements of the energy codes.
The key is that our patented composite technology bonds light-gauge steel with EPS to create composite material panels capable of carrying unusually heavy loads. Our panels are treated for smoke and flame retardancy, making them noncombustible assemblies. While the panels are safe for humans and do not off-gas, they are free of pests such as termites, bees and rodents, since they offer no food value.
We are a 100% waste-free production factory with low carbon emissions, and we incorporate recycled materials into the panels where possible.
