structural insulated panels


this is one of the products used in sustainable design today.Although foam-core panels gained attention in the 1970s, the idea of using stress skinned panels for construction began in the 1930s. Research and testing of the technology was done by Forest Products Laboratory as part of U.S. Forest Service's attempts to conserve forest resources.
SIPs are most commonly made of OSB panels sandwiched around a foam core That is made of expanded polystyrene (EPS), extruded polystyrene (XPS) or rigid polyurethane foam, but other materials can be used. Some SIPs use fiber-cement or plywood for the panels, and agricultural fiber, such as wheat straw, for the core.
