About Panels

ThermaSteel’s patented composite joining technology bonds light gauge steel structural members together with EPS, delivering a stronger, lighter wall system which installs faster, and performing as structural framing, insulation, sheathing and vapor barrier — all in one.

See the different types of ThermaSteel panels in application with this video (2 min):

XPanel – Exterior Wall Panel

• Used mainly for exterior wall applications
• 5.5″ or 7.5″ thick, up to 4′ wide and 12′ tall
• 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 42,000 plf load LRFD
• Ready for direct application of final skin

IPanel – 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!

FPanel – 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

RPanel – 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

HPanel – Hurricane Panel

SPanel – 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.

BPanel – 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

CPanel – 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.
