Why Homeowners Choose Fiberglass
Structural Strength
Fiberglass is a strong, dimensionally stable material, which can allow for slimmer frames and larger glass areas in a given opening.
Dimensional Stability
Fiberglass expands and contracts with temperature changes at a rate closer to glass than many other frame materials, which can help maintain a tight seal over time.
Paintable Finish
Unlike vinyl, most fiberglass frames can be painted, giving you the flexibility to change frame color down the road.
Clean, Architectural Lines
Fiberglass frames are well suited to homeowners who want a refined, low-profile look without sacrificing structural performance.
