What Is ThermaSteel

ThermaSteelThe ThermaSteel Building System is a unique patented process utilizing the power of composite technology consisting of structural grade steel and Expanded Polystyrene (EPS).

Opposing double steel framing members are bonded with rigid, fire retardant Expanded Polystyrene (EPS) to form a composite building component that provides structural framing, insulation, sheathing, and a vapor barrier in one, fast, high-tech step.

This material is light weight, weighing an average of 49 pounds for a 5.5″ thick 4’x8′ panel. The composition of the panels avoid thermal bridging which, in turn, increases the effective R Value of the walls, floors, or roofs by 138% over that of a traditional wood or steel frame building with 6 inch walls and R-19 bat insulation. More about the R-Factor Comparison.

ThermaSteel components may be used for exterior and interior walls, partitions, floors, and roofs. Combinations of pre-insulated components are screwed together to form a unique high performance energy shell that is fast, lightweight and extremely strong with superior thermal properties. Rough openings for doors and windows are formed during the manufacturing process.



ThermaSteel is green and green is ALWAYS tied to health. It is one of four basic divisions of environmentalism. So when anyone references Green, they should be addressing a health benefit of the item. These are generally viewed in immediate and long-term health concerns. More about green.



ThermaSteel is Sustainable. Sustainable building materials help lighten the footprint of any construction project. Sustainable products reduce the impact on the environment by using products that are either completely renewable or gathered in a way that doesn’t mar the surrounding area.

ThermaSteel is Economical. Indeed, sustainable building materials are not only eco-friendly, but they are wallet friendly also: they help reduce the operating costs of a building by lowering energy needs. More about economical.
