This investigation was undertaken jointly by the Mineral Industry Research Laboratory and the Institute of Business, Economic and Government Research at the University of Alaska. It is one of a continuing series of studies concerning the market and utilization rate for selected structural materials within Alaska. The overall objective of these studies is to identify opportunities for the regional manufacture of selected building products. In this manner, this limited study of insulation markets complements more extensive previous studies concerning Alaskan cement and clay products, markets and manufacturing feasibility.
