Fiberglass refers to a strong, lightweight material that consists of thin fibers of glass that can be transformed into a woven layer or used as reinforcement. Fiberglass is less strong and stiffer than carbon fiber-based composites, but less brittle and cheaper.

Fiberglass Reinforced Panels (FRP) are plastic sheets that come in both flat and corrugated options. They have a wide variety of uses including roofing, skylights, wall covers, greenhouses, and more.
