About Panels

Insulated Wall 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 performs as structural framing, insulation, sheathing and vapor barrier — all in one. When it comes to modern construction, insulated wall panels are redefining what’s possible—delivering energy efficiency, structural integrity, and sleek design all in one system. Whether you’re building a commercial facility, outfitting a cold storage unit, or simply aiming to reduce labor costs on your next project, insulated panels offer a smart, high-performance solution.

Designed for durability and easy installation, these panels are used across a wide range of building projects throughout the United States. With superior thermal performance and long-term cost savings, insulated wall panels are quickly becoming the go-to choice for architects, contractors, and developers who refuse to compromise on quality.

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 40 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.

What Are Insulated Wall Panels?

Insulated wall panels are high-performance building components that combine structural support and insulation into one efficient wall system. Designed to streamline construction and boost energy efficiency, these panels consist of an insulating foam core—typically rigid foam insulation or fiberglass insulation—sandwiched between durable outer layers, often metal or structural sheathing.

Compared to traditional wall systems that require multiple layers of framing, insulation, vapor barriers, and exterior finishes, insulated wall panels simplify the process while delivering superior thermal performance. They reduce labor costs, speed up build times, and offer a cleaner, more consistent installation.

There are several types of insulated panels available to meet different performance requirements:

• Insulated Metal Panels (IMPs): Featuring metal facings and an insulating foam core, these panels are ideal for commercial and industrial buildings where strength and thermal efficiency are critical.
• Structural Insulated Panels (SIPs): These panels use rigid foam insulation between structural facings, offering excellent load-bearing capacity and air-tightness.
• Insulated Metal Wall Panels: A popular subset of IMPs designed specifically for wall applications, offering enhanced moisture resistance, fire protection, and long-term durability.

Together, these wall panel systems provide a smart, long-term building solution for a wide range of projects—from office buildings and warehouses to smart homes and cold storage facilities.
