What is a SIPs roof? This guide explains how structural insulated panels span between supports while insulating the roof in one operation. Each panel uses rigid insulation bonded between structural skins. It covers why SIPs suit fast, airtight construction, the risks of cutting or damaging panels, and how to route services without harming structural or thermal performance.
