Structural insulated panels, or SIPs, are high-performance building panels used in both residential and commercial construction. The panels consist of an insulating foam core sandwiched between two structural skins of oriented strand board (OSB). SIPs are strong, energy-efficient, and provide a great deal of flexibility in design and construction.
SIPs were first developed in the 1930s, but they started gaining popularity in the 1970s as a more energy-efficient alternative to traditional stick-framed construction. Today, SIPs are used in everything from single-family homes to high-rise commercial buildings.
One of the most significant advantages of SIPs is their energy efficiency. The foam core of SIPs provides a continuous layer of insulation, which helps to keep homes and buildings more relaxed in the summer and warmer in the winter. This can lead to significant savings on heating and cooling costs over the life of the building.
