What ThermaSteel Metal SIP Panels Bring Into One Building Component
Metal SIP Panels in Colorado let project teams combine several building functions into one factory-produced component. Our panels bond light-gauge steel structural members to an EPS insulation core, with sheathing and vapor control incorporated into the assembly. The result is one panel that provides structural framing, insulation, sheathing, and a vapor barrier, eliminating the need to assemble those functions separately on the jobsite.
The steel framing is positioned to create a thermal break between the interior and exterior components, while the EPS core provides continuous insulation through the panel. Panels can be manufactured to project dimensions and prepared with openings and other requirements before shipment. That means your team can receive numbered panels with corresponding drawings and accessories ready for installation instead of starting with raw framing materials and building the complete assembly in the field.

One Panel Line for Multiple Construction Applications
Different portions of a building call for different panel configurations. We manufacture panels for exterior and interior walls, roofs, concrete floors, shear walls, hurricane applications, foundations, and ceilings, allowing the panel type to be selected according to the intended use.
Exterior & Interior Wall Panels
X Panels are primarily used for exterior walls in 5.5- and 7.5-inch thicknesses, with effective thermal performance from R51 to R61. They accommodate structural studs on both faces and are ready for direct application of the final skin. I Panels are designed mainly for interior walls and tiny homes, providing R28 performance at 3.5 inches thick and supporting dimensions up to 4 feet wide by 12 feet tall.
Roof & Concrete Floor Panels
R Panels provide insulated roof construction in 5.5- and 7.5-inch configurations, with effective thermal performance from R51 to R61. Their load-bearing design can reduce the need for conventional trusses and accommodate cathedral ceilings and A-frame applications. F Panels serve as stay-in-place forms for reinforced concrete floors, with the 7.5-inch panel providing R58 insulation and spanning up to 40 feet clear with minimum shoring under specified conditions.
Hurricane, Shear & Below-Grade Panels
H Panels are designed, tested, and certified for hurricane applications up to 185 MPH, including flying-debris conditions. S Panels support shear wall applications with thermally broken construction and structural bracing. B Panels are used for foundations, knee walls, and retaining walls, with the 7.5-inch configuration providing R61 performance for below-grade applications subject to applicable design requirements.
Ceiling Panels for Interior Applications
C Panels provide interior ceiling construction under trusses or on bearing walls. Available in 3.5- to 7.5-inch thicknesses, they offer effective thermal performance from R28 to R61 depending on configuration and can be pre-chased for direct sheathing attachment.

Structural Insulated Panels for Colorado Project Specifications
Structural Insulated Panels in Colorado can be specified across multiple building-envelope applications, but the appropriate configuration depends on the building type, loads, climate, and intended use. Available panels range from R28 effective thermal performance for interior applications to R61 in applicable exterior wall, roof, shear, and below-grade configurations.
Our panel assemblies are thermally broken, mold-resistant, smoke- and fire-resistant, and non-combustible. Available configurations also support energy-code-compliant construction, while panel thickness, steel gauge, stud configuration, and application can be selected according to project requirements.

How Our Panel Construction Handles Key Project Requirements
Continuous Insulation Through the Panel
Energy-efficient Metal SIP Construction in Colorado starts with the insulation core and the way it works with the structural framing. Our panels use EPS through the assembly, while the separation between interior and exterior steel components creates a thermal break that helps limit direct heat transfer through the framing. Effective thermal performance reaches R61 in applicable configurations.
Mold, Smoke & Fire Resistance
Our panels are mold-resistant and smoke- and fire-resistant. The assemblies are treated for smoke and flame retardancy and identified as non-combustible assemblies in current product information.
Four Functions in One Assembly
Each panel brings together structural framing, insulation, sheathing, and vapor barrier functions. That reduces the number of separate layers that must be coordinated during wall construction and allows the panel to arrive as a prepared building component.
Prepared Before It Reaches the Jobsite
Our panels can be manufactured around project dimensions and openings, then numbered and supplied with corresponding drawings and accessories. Shop drawings can integrate rough openings, beams, and headers so installation teams can work from a coordinated panel layout.
Metal SIP Panel Construction Across Colorado
Structural Insulated Panel Buildings in Colorado can include custom homes, multifamily developments, offices, warehouses, industrial facilities, agricultural buildings, and specialty structures. Panels are manufactured for the requirements of the individual project, so location is only one part of determining the appropriate configuration. Building type, application, dimensions, structural requirements, and thermal performance all factor into the panel selection.
We work with project teams throughout Colorado, including:

Why Colorado Project Teams Work With Our Manufacturing Team
Resources for Architects, Engineers & Contractors
Design and construction teams can work from shop drawings, load information, connection details, specifications, testing documentation, and other technical resources when evaluating and specifying the panels. Our team can also coordinate with architects and engineers during project development.
Manufacturing for Diverse Building Types
The same product line covers exterior and interior walls, roofs, floors, foundations, shear walls, ceilings, and specialty applications. That range allows project teams to evaluate panel construction across different portions of a building, instead of limiting the product to one application
More Than Five Decades of Manufacturing
Panel manufacturing began in 1970, and more than 75,000 projects have used the product worldwide. That experience spans residential, commercial, industrial, military, aerospace, institutional, and specialty construction.
Project-Specific Panel Production
Nearly every project can be custom-designed around its intended application. Panel production can account for dimensions, rough openings, roof requirements, panel types, and other project-specific details before manufacturing begins.
