Aluminum foil-faced glass wool rolls are highly efficient thermal and acoustic insulation materials. Composed of high-quality glass fibers bonded together with a durable resin, these rolls feature an aluminum foil layer that enhances thermal insulation and serves as a vapor barrier. They are widely used in residential, commercial, and industrial buildings to provide superior insulation for walls, roofs, and HVAC systems. Their lightweight, flexible design allows for easy installation, while the aluminum foil facing offers excellent resistance to moisture, fire, and corrosion, ensuring long-lasting performance.
