Structural Insulated Panels (SIP): The High-Performance Wall and Roof Construction System
Structural Insulated Panels (SIPs) sandwich rigid foam insulation between OSB or other structural facings creating wall and roof panels. SIPs provide structure, insulation, and air barrier in single component. High R-values, fast erection, and low air leakage benefit residential and commercial construction. Understanding SIPs helps contractors evaluate this construction system.
