Introduction to SIPs
Most structural insulated panels (SIPs) are load-bearing laminates of foam and wood sheathing materials used for building the exterior walls, roof, floor and even foundations in homes and commercial buildings. Manufactured in factories, the panels are shipped by truck to a building site and assembled by framing crews. When properly assembled, the resulting home or commercial building provides an extremely strong, well-insulated and comfortable building shell. Some 60 different companies manufacture panels throughout North America.
A structure built with SIPs looks the same from the outside as any other. Yet its strength and efficiency characteristics are exceptional. Tests performed by national laboratories prove the product's energy efficiency. And SIP structures that have survived hurricanes, earthquakes, tornadoes and even indoor fires attest to SIPs extraordinary strength. These and other benefits are generating plenty of news coverage and lots of sales.
