For more than 28 years, Insulspan has led the industry in the development and manufacture of structural insulated panels. In 2007, Insulspan SIPs were named the number one green building product by the editors of Sustainable Industries magazine. In the words of the judges, “Not all SIPs are created equal, and Insulspan is the best.” Still, we’re not resting on our laurels. Insulspan continues to pursue innovation in structural insulated panel fabrication and performance.
