The Pella® Impervia® line couples style with strength in fiberglass windows and patio doors that, as the name implies, are impervious to nearly all types of weather.
Pella’s proprietary fiberglass is the strongest material for windows, engineered for lasting durability.1 Our exclusive fiberglass will never rot or corrode, and it resists dents, bends and breaks. Duracast stands up to weather from severe heat to frigid cold, making Pella Impervia windows and exterior doors exceptional for all regions.
The outstanding insulating features of our fiberglass replacement windows and patio doors boost comfort and help conserve energy. Optional foam-insulating frames can be included on these ENERGY STAR®-certified windows and patio doors.

With a wide selection of colors to explore, you'll find windows and patio doors to complement your clients' tastes. Our environmentally friendly paint process virtually removes toxic chemicals, helping indoor air stay clean.
