Surface Veil

The surface of the acoustic ceiling tile is coated with a layer of fiberglass veil. This non-woven fabric is created from glass fiber filaments woven into a mesh structure and bound with resin. It provides excellent thermal insulation, high temperature resistance, superior sound absorption, and strong resistance to both acid and alkaline corrosion. Fiberglass surface veil comes primarily in white, we can also customize colors.
