Spun Glass

Spun Glass

Spun glass, also known as glass wool or fiberglass, is a type of insulation material made from fine fibers of glass. The manufacturing process involves melting glass and then spinning it into thin fibers using a high-speed spinning machine. These fibers are then collected and compressed into different forms, such as rolls, batts, or loose-fill. Spun glass has several properties that make it an excellent insulation material. First, it is a poor conductor of heat, which means it can effectively reduce heat transfer between two surfaces. Second, it is lightweight and easy to install, making it a popular choice for both residential and commercial buildings. Third, it is non-combustible, which means it does not burn or release toxic fumes in case of a fire. However, spun glass also has some drawbacks. It can irritate the skin, eyes, and respiratory system if inhaled or touched without proper protective gear. Additionally, it is not as effective as other insulation materials, such as spray foam or cellulose, at reducing air leakage and noise transmission. Despite its limitations, spun glass remains a popular choice for insulation in many applications. It is commonly used in walls, attics, and roofs of buildings, as well as in industrial equipment and appliances.
