Thermal conductivity is the measure of a material's ability to conduct heat. It is an important property to consider when choosing insulation materials for buildings, as materials with low thermal conductivity provide better insulation and reduce heat transfer through walls, roofs, and floors. Glass wool is a common insulation material that is widely used in construction due to its low thermal conductivity and excellent insulation properties. What is Glass Wool? Glass wool is a type of insulation material made from glass fibers that are formed into a wool-like texture. The glass fibers are produced by melting silica sand, limestone, and soda ash at high temperatures, which are then blown or spun into fine fibers. The fibers are then mixed with a binder and compressed into mats or rolls, which are then cut to size and used as insulation. Glass wool has several advantages over other insulation materials, including its low thermal conductivity, excellent acoustic insulation
