Introduction to Glass Wool Insulation
Glass wool insulation is a popular and effective thermal insulation material. It is made from molten glass that is spun or blown into fine fibers. These fibers create a porous structure that traps air, which significantly reduces heat transfer. Glass wool insulation offers excellent thermal performance, sound – absorption capabilities, and is non – combustible, making it a safe choice for a wide range of applications, including residential, commercial, and industrial buildings, as well as in HVAC systems.
