ThermaSteel
ThermaSteel utilizes patented composite joining technology that bonds light gauge steel structural members with EPS (expanded polystyrene), creating an advanced wall system that serves as structural framing, insulation, sheathing, and a vapor barrier all in one.
Key Benefits:
Energy Efficiency: Offers up to R-61 effective R-Value, reducing heating and cooling costs by 75% or more, ideal for Net-Zero and Passive House designs.
Sustainability & Safety: Life expectancy of 425 years, mold & mildew resistant, fire resistant, recyclable, and produced in a zero-waste facility.
Construction Efficiency: Lightweight 4-in-1 load-bearing panels cut framing time by 50%, with pre-cut, diagrammed, and labeled panels for easy assembly.
Versatility: Customizable for projects ranging from sheds to mid-rise buildings, offering exterior, interior, below-grade walls, floors, and roofs.
