Insulfoam, one of the most respected names in polystyrene-based construction products is now even better. In May of 2007, Carlisle Construction Materials, a company known for its single-ply roof systems and waterproofing products, further broadened its product offering by acquiring Insulfoam, the largest manufacturer of expanded polystyrene (EPS) in North America. The Insulfoam acquisition confirms Carlisle's overall commitment to architects, building owners and contractors who want to promote and utilize energy-efficient construction products.

Insulfoam's Premier SIPS division is North America's largest Structural Insulated Panel Manufacturer. Used in Commercial & Residential construction to replace typical stick frame construction, SIPS offer exceptional energy efficiency, an elegant modern system, significant labor savings, faster close-in, and a true, square frame--every time.
