Below is a list of Fiberglass Panels manufacturers from San Jose, California. Fiberglass panels are composite fiberglass products that have been molded into a flat shape. They may be detailed, curved, textured or made for a specific function, like a car door interior. They are made mostly of fiberglass reinforcement, which is composed of chopped or woven fiberglass threads and a thermoplastic resin, which when combined form a strong, chemically resistant material. It is light in weight and is therefore easy to transport, install and handle.
