Glass wool blanket, also known as glass wool roll, is a flexible and lightweight insulation material made from spun glass fibers. It is commonly used for thermal and acoustic insulation in walls, roofs, ceilings, and HVAC systems. The blanket form allows for easy installation over large surface areas, making it ideal for both residential and industrial buildings. With excellent fire resistance, sound absorption, and thermal performance, glass wool blanket helps improve energy efficiency and indoor comfort while reducing noise levels.
