Fiberglass serves a number of useful purposes, but the most important application of fiberglass is as insulation used primarily to control temperature in industrial operations. Fiberglass insulation is a cost-effective, energy-saving product that saves money for businesses through lower utility bills. In addition, adequate levels of fiberglass pipe insulation for industrial processes have helped make industry more efficient and more profitable by cutting energy losses and decreasing production costs. By avoiding the added energy generation necessary to heat and cool equipments, fiberglass insulation continues to be a benefit to the environment by helping to reduce pollution emissions.
