Fiberglass Blanket Insulation is a flexible, lightweight insulation material made from fine glass fibers. It is commonly used for thermal and acoustic insulation in residential, commercial, and industrial buildings. Supplied in rolls (with or without foil backing), it is easy to install in walls, ceilings, floors, and ductwork. This cost-effective solution delivers reliable energy savings and noise control while being fire-resistant and non-corrosive.
