Fiberglass is created by pulling strands of glass through a heated die, resulting in a material that is strong, resilient, and suited to all weather conditions. Essentially a carbon fiber product, it has been used for many purposes, including boats, satellites, bridges, and goalie masks, where it is subject to extreme temperatures and constant abuse.

Fiberglass can meet a wide variety fenestration needs, from design, to durability, to performance objectives. Learn why fiberglass is an optimal framing material by exploring its characteristics in the tabs below.

 For upgraded performance and greater size capabilities, select from Series 458 or 658. With deeper, more robust frames, FiberWall™ can deliver dramatic walls of glass that cannot be achieved with vinyl, and offers superior R-values to thermally broken aluminum.
