Fiberglass (and composites)

The newest option from manufacturers, fiberglass and other composites are rapidly gaining in popularity due to their durability, color options, strength, and appearance. Fiberglass is made of many strands of fiberglass embedded in resin, which is molded and then given a baked on finish. The finish applied is much more durable than materials used in cars, boats, and other common applications of the material. As a material, fiberglass is 2-10 x stronger than wood or vinyl and doesn't expand and contract which makes it an ideal material for hot or cold climates. Some manufacturers will apply wood veneers for an enhanced interior appearance, while others use the material as a cladding applied to wood frames.

Fiberglass window Advantages

• Excellent strength & durability
• Pre-finished material can be repainted
• Material stability may extend insulated glass life
• Many glass & grid options
  

• Generally more expensive than vinyl
• Custom radius shapes not generally available
• Some limitations in sizes, types (by manufacturer)

Best applications:

• Projects where future color flexibility is important**
• Projects where durability is important
• Projects where strength, wind load
  resistance are critical
• Fiberglass window exteriors are finished before shipping. The nature of the finish allows, but does not require, painting
