What are Structural Insulated Panels?

Structural Insulated Panels (SIPs) are used as a replacement for traditional exterior framing, insulation, and sheathing in both residential and commercial buildings. They are made of an EPS foam core with OSB skins on both sides, adhered together with commercial-grade polyurethane adhesive. This construction method makes them similar in design to an I-beam.
