Strong, stable and slim.
Fiberglass frames are strong, resist expanding and shrinking and can be painted, giving slim sightlines and long-lasting performance in extreme weather.
- Strength: Very rigid, slim frames
- Stability: Little expansion and contraction
What it is, and why it matters.
Fiberglass is a strong, stable material that moves very little with temperature, so seals stay tight. Frames can be slimmer, giving more glass, and they accept paint. They are a good fit for extreme climates and large windows.
We help you weigh fiberglass against vinyl and wood: it costs more than vinyl but offers strength and stability. We install with careful insulation and sealing, and talk through finishes.
