Strength, Efficiency, and Comfort All in One

The Future of Structural Insulated Panels

Introducing ThermaSteel Panels

Explore Our Wide Range of Steel Structural Insulated Panels

At ThermaSteel West, we pride ourselves on our patented composite joining technology, which effectively bonds light gauge steel structural members with EPS (expanded polystyrene). This groundbreaking innovation results in a stronger and lighter wall system that significantly reduces installation time.

Our panels perform not only as structural framing but also provide insulation, sheathing, and vapor barriers - all in one solution. With exceptional thermal performance ratings ranging from R28 to R61, our panels are engineered to offer superior energy efficiency, making them the ideal choice for both residential and commercial projects.

From exterior walls to hurricane-resistant panels, we offer a diverse range of product options tailored to meet the unique needs of any construction project. Explore our selection of X, I, F, R, H, B, S, and C panels, each designed with cutting-edge technology to maximize performance and durability.

  • Ready for direct application of final skin
interior wall panel

Panel - Interior Wall Panel

  • Used mainly for interior wall applications or tiny homes
  • 3.5″ thick up to 4′ wide and 12′ tall
  • Effective thermal performance of R28
  • 4 structural studs on both faces of the panel (16″ o.c.)
  • If you are looking for a quiet room or DIY, this is your panel!
Panel – Concrete Floor Panel

Panel – Concrete Floor Panel

  • Stay in place form for concrete slabs
  • 7.5″ thick R58 insulation, 4′ wide 12′ long
  • Two 8″ wide channels for rebar in the reinforced beams
  • Capable of spanning up to 50 ft clear with minimum shoring
  • Reduces concrete by 40% (average section is 58 psf)
  • High STC rating fire stop between floors
  • Reduces labor time by over 60%
  • 5 studs to hang ducts or attach sheathing directly
roof panel

Panel - Roof Panel

  • 5.5″ or 7.5″ thick up to 4′ wide and 12′ long
  • Effective thermal performance of R51 to R61
  • 4 or 5 structural studs on both faces of the panel (16″ or 12″ o.c.)
  • Load bearing means we can reduce trusses by 2/3 (every 4-6 ft o.c.).
  • 2 panels can connect directly allowing for cathedral ceilings and A frames without supports
Panel – Hurricane Panel

Panel - Hurricane Panel

  • Designed, tested, and certified to withstand 185mph, including flying debris
  • 5.5″ or 7.5″ thick up to 4′ wide and 12′ long
  • Effective thermal performance of R51 to R61
  • 4 or 5 structural studs on the interior faces of the panel (16″ or 12″ o.c.)
  • 11 studs on the exterior face making it projectile-safe
Panel - Shear Wall Panel

Panel - Shear Wall Panel

  • 5.5″ or 7.5″ thick up to 4′ wide and 12′ tall
  • Thermally broken with three horizontal bracings
  • Effective thermal performance of R51 to R61
  • 4 or 5 structural studs on both faces of the panel (16″ or 12″ o.c.)
  • Up to 2,420 plf with a 2.0 safety factor

Studs of ThermaSteel panels are turned sideways (creating a thermal break), orienting the strong side of the stud in the shear direction, effectively making every panel a shear panel.

panel - below grade panel

Panel - Below Grade Panel

  • Used for foundation, knee walls, and retaining walls
  • 7.5″ thick 1.5 density up to 4′ wide and 12′ tall
  • Thermally broken with three sections and thermal performance of R61
  • 4 or 5 structural studs on both faces of the panel (16″ or 12″ o.c.)
  • Check the below grade manual for design guidelines and limitations
panel - ceiling panel

Panel - Ceiling Panel

  • Used as interior application under the truss or on the bearing walls
  • 3.5″, 5.5″ , or 7.5″ thick up to 4′ wide and 12′ long
  • Effective thermal performance of R28 to R61
  • 4 structural studs on both faces of the panel (16″ o.c.)
  • Pre-chased and ready to directly attach sheathing.
