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 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.

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.
