General Purpose Glasswool is a light weight flexible blanket designed for external lagging of low to medium temperature industrial equipment and appliances. It is used for applications such as air-conditioning ductwork, hot water tanks, and as an effective energy saver on process vessels operating up to 340 Degree Celsius. It is sufficiently flexible to wrap around sharp angles and small radii with sufficient compressive strength to maintain thickness.
