The use of SIPs brings many benefits and some drawbacks compared to a conventional framed building.
The cost of SIPs are higher than the materials for a comparable framed building. A well-built home using SIPs will have a tighter building envelope and the walls will have higher insulating properties, which leads to fewer draughts and a decrease in operating costs. Also, due to the standardized and all-in-one nature of SIPs, construction time can be less than for a frame home, as well as requiring fewer tradespeople.
The lightweight core keeps the two faces in the correct position, resists shear forces, and provides insulation, while the two faces provide durability, weather and impact resistance, and resist in-plane forces of tension and compression.
