What Are SIP Panels?
Structural Insulated Panels (SIPs) are advanced building components made of a high-performance insulating foam core sandwiched between two structural boards (typically OSB). This structure creates a strong, airtight, and highly insulated building envelope that outperforms traditional brick-and-block construction in energy efficiency and speed of build.
