Fiberglass Windows

Trusted in tools, boats, bridges and more, fiberglass is a naturally strong and durable material, making it a superior choice for windows. Pella’s proprietary fiberglass material is the strongest material for windows, engineered for lasting durability.⁹ Our exclusive fiberglass will never rot or corrode, and it resists dents, bends and breaks.

Fiberglass Window Benefits

Durable and Strong

The best fiberglass windows for your home are incredibly strong and durable. Resisting dents, bends and breaks, fiberglass window frames have virtually no expansion and contraction to help improve energy efficiency, reduce the risk for seal failure and provide long-term stability for dependable operation.

Weather Resistant

Fiberglass is designed to provide outstanding resistance to water, wind and outside noises. It can withstand large temperature swings and the rigorous performance requirements of a commercial building.

Maintenance-Free

Durable fiberglass material will never rot or corrode and is naturally resistant to water and bugs. It resists chipping, chalking and fading – so you never need to paint or refinish your fiberglass windows.

Factory-applied and baked on, our long-lasting powder-coat finish resists chipping, chalking and fading – even in dark colors – for enduring beauty.
