As a leading producer of methylene diphenyl diisocyanate (MDI), Huntsman works closely with customers that manufacture rigid foam insulation board (boardstock/insulation board and block) for residential and commercial construction applications. Boardstock can be faced (covered) with a wide variety of materials including paper, aluminum, kraft, fiberglass, gypsum, perlite, oriented strand board (OSB) and fiberboard.

Because of its light weight, boardstock can be easily installed as cavity insulation; on flat or pitched roofs or as insulated sheeting in timber-framed buildings. Depending on building requirements, boardstock can be cut into a variety of shapes and sizes. Additionally, it can be used for pipe insulation, industrial applications (tanks, fittings, valves), refrigeration applications, and for the transportation industry (refrigerated trucks).
