A panel that combines structure and insulation in one unit, used for walls and roofs to build very energy-efficient buildings.
A structural insulated panel (SIP) is a high-performance building panel consisting of a rigid foam insulation core sandwiched between two structural facing boards, typically OSB. SIPs serve as walls, roofs, and floors simultaneously providing structure, insulation, and an air barrier. Buildings using SIPs are extremely energy efficient and can be erected quickly.
