"We've got you covered"

Our Structural Insulated Panels have been used for over 25 years by the Timber Frame Industry. Structural Insulated Panels are constructed in the same manner as Integrated Structural Insulation Panels, ISIP® without the structural lumber, as the Frame itself provides the structure. Stress Skin Panels attach with mechanical fasteners to the frame and provide sheer strength for the structure.
We offer different methods for joining the Stress Skin Panels. The most common is the 2x spline located 48” on center. On the roof panels we use a double OSB spline with a foam keyway to prevent air transfer through the joint.

Typical wall thicknesses are 4" and 6" with 8" or 10" panels on the roof. The interior can be sheathed with your choice of drywall or OSB.
