SIP Panels That Bring Structure and Insulation Together

Structural insulated panels combine a rigid insulation core with structural framing and exterior skins to create a high-performance building component. ThermaSteel panels bring these functions together before they reach the jobsite, helping project teams reduce separate installation steps while creating a more continuous building envelope. Our insulated metal SIP panels can be manufactured around project dimensions, openings, configurations, and performance requirements.

✓

Structural Support

Steel framing provides load-bearing capacity within the panel assembly.

✓

Continuous Insulation

The insulated core helps reduce thermal bridging through the building envelope.

✓

Factory Precision

Panels are cut, prepared, diagrammed, and labeled before delivery.

✓

Faster Assembly

Multiple building functions arrive as coordinated components ready for installation.

✓

Flexible Applications

The system can accommodate residential, commercial, industrial, agricultural, and specialty projects.
