Structural Insulated Panels (SIPs)

Factory-made panels consisting of a rigid foam insulation core (EPS, XPS, or PIR) bonded between two structural facings of oriented strand board (OSB). SIPs provide structure, insulation, and airtightness in a single system and can be erected quickly. They are popular for timber frame extensions and garden rooms where high thermal performance and speed of construction are priorities.
