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, VA 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

If you want to build a church in northern Russia (1991) or an Of The Grid emergency unit for the government – we do it all.

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-values (up to R61), compliant with ASHREA 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 allows us to bond 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 the panels noncombustible assemblies. While the panels are safe for humans and do not off-gas, they are free of pests such as termites, bees, rodents, and more, since they do not offer any food value.

We are a 100% waste-free production factory, with low carbon emission, and we incorporate recycled materials into the panels where possible.

Check our resources page for certifications, including:

  • IAPMO load bearing tables for II-V construction type
  • 2hr fire test for a load bearing wall
  • Florida hurricane rating
  • Government vendor
  • 9.5 Richter scale by Russia
  • Below grade application

In our user-friendly process, our drafts-people will work with your engineer and architect, and panelize your project into shop drawings to integrate rough openings, beams, and headers to allow you to construct the building of your dreams. The panels will arrive to your job site ready to be installed.

  • “The strongest building I’ve ever encountered.”

    On September 6th, 2017, the Caribbean Beacon radio station on the island of Anguilla was devastated by Hurricane Irma. The eye wall wind speeds of 225mph with gusts up to 250mph was the equivalent of an F4 tornado parked on top of our station for over an hour. Our shortwave feed line was ripped from the building, the 14 foot tall feed line support poles bent like rubber. The two 120 foot shortwave antenna towers were twisted, the AM combiners were hurled 700 feet across the property and the 360 foot tall AM radio tower fell like a noodle on top of our reinforced ThermaSteel building. From the initial reports I expected a total loss, but when I arrived 5 days later I was amazed at the actual condition of the building.

    The concrete roof and eves were crushed directly under where the tower fell, puncturing the roof structure in several places. The steel I-beam bent and twisted under the tremendous impact, but held in place. Most any structure subject to that wind speed and compromised with a partial collapse would have come completely apart. Your building held together and did its job wonderfully. The structure stayed intact and protected the contents including our transmitters, switchgear, safety switch and generator. We will be repairing this building and our future plans will include Thermasteel buildings and room additions.

    Thank you for engineering the strongest building I’ve ever encountered.

  • “Your ThermaSteel building has just passed the most severe test that nature could have hurled at it.”

    Your ThermaSteel building has just passed the most severe test that nature could have hurled at it during the recent visit by hurricane “Luis”.

    Anguilla took a direct hit with “Luis” as the eye of the storm passed immediately over the island on September 5th. The island sustained winds of over 175mph for nearly 10 hours. The windows in the nearby Airport Control Tower were designed to withstand 200 mph winds yet all the windows were blown out at the height of the storm! Needless to say, all eyes were on our new “ThermaSteel” building.

    The only damage done to the building was when a 40 foot container sitting on the ground some 15-20 feet away from the north wall, was picked up, overturned, and thrust into the side of the building. The two corner panels can be replaced easily with no affect on the structural integrity of the building. I am thankful it was not a brick wall structure! The million dollar transmitter installation inside suffered absolutely no damage whatsoever.

  • “… an 84% reduction in utility cost over what I was used to paying.”

    We recently completed our all ThermaSteel home in Quitman, Texas, about 80 miles outside of Dallas. It ended up being 1,500 sq. ft. with 15′ cathedral ceilings. I’m a native Texan and have lived in Texas all my life. It is a well known fact that Texas can have the most fickle weather on earth… boiling one minute and hail hitting you in the face the next.

    I have always lived in conventionally built homes and am used to $200+ heating and cooling bills per month in these heavy stress months. I was very anxious to see how my ThermaSteel home would benefit my monthly savings. To my surprise the bill for my first two months, July and August came to just $32.

    According to my calculations that’s an 84% reduction in utility cost over what I was used to paying. If you would like to have anyone call for verification please feel free to give them my number.

  • “… in one of the coldest months of the winter the bill was just $42.71. That’s what I call economical!”

    I have been living in my ThermaSteel home now for more than five years and I have to say that it has saved me a small fortune in heating bills. I live in Radford, VA. It’s up in the mountains in the southwestern part of the state where it gets snowy and cold. I have enclosed some of the heating bills for the coldest part of the months and as you can see it doesn’t take much to keep us comfortable in our ThermaSteel home. In September our bill was only $0.45, but in one of the coldest months of the winter the bill was just $42.71. That’s what I call economical!

    We love our home because it’s cozy, comfortable, and easy to maintain. We have never had a nail pop and our walls are as straight as the day we moved in. When the snow is on the roof you can tell our home is ThermaSteel because you don’t see the uneven melting of the snow like on the other roofs. If a person wants to live in total comfort economically I would highly recommend building out of ThermaSteel.

    Thanks for producing such a great building system.

  • “… very pleased with the product, both for the thermal insulation and especially the ease of installation.”

    I first used the Thermasteel product in 1996. I was very pleased with the product, both for the thermal insulation and especially the ease of installation.

    Even not being carpenters or builders, we were able to assemble the panels and finish the job. We had to learn how to do such things as anchor the interior walls to the framing and construct a second floor and roof structure. We used the panels for all exterior walls and roof. When the air conditioning subcontractor performed his tests, he was amazed at the insulation ratings. We did put fans in all rooms and an air conditioner was not required much of the time to maintain a constant temperature. We are in Florida, and this construction product was excellent. I have since sold the unit, the fact that it was construction of ThermaSteel panels increased the resale value.

    I am currently looking to build another home. This year 2017, I looked up ThermaSteel and talked with them again about using their product for construction. The fact that they have been in business this long speaks well for them. We are working on design now and hopefully this month will have plans ready for an estimate. The savings in insulation, construction time and expense, quality and long-term energy savings makes this product a choice alternative for anyone.
