Step-by-step explanation:
Stress-skin panels, also known as SIPs (Structural Insulated Panels), are a type of building material used in construction. They consist of a rigid foam insulation core sandwiched between two structural boards, usually made of oriented strand board (OSB) or plywood. SIPs provide excellent insulation and structural support, making them a popular choice for energy-efficient and sustainable construction projects.
