Glass Wool

Glass wool is a thermal and acoustic insulating material made from thin filaments of glass fibers. Because of its excellent insulating properties and ease of installation, glass wool is the material of choice for insulating buildings, homes and other structures.
Glass wool is made by melting glass and then spinning it into fibers. The fibers are then treated with an adhesive to bind them together and then formed into strips, rolls or sheets. The resulting product is lightweight, flexible and easy to install.
