The Pella® Impervia® line blends style with durability in fiberglass windows and patio doors that, as the name infers, 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 defends against weather from extreme heat to subzero cold, making Pella Impervia windows and exterior doors great for all climates.
The impressive insulating properties of our fiberglass replacement windows and patio doors boost comfort and help reduce energy use. Optional foam-insulating frames can be added to these ENERGY STAR®-certified windows and patio doors.
Pella® Impervia® windows and sliding patio doors come prefinished with a factory powder-coat finish that maintains its looks for a long time—inside and out—with little upkeep. With an array of colors to select, you'll find windows and patio doors to reflect your clients' tastes. Our environmentally friendly paint process essentially gets rid of toxic chemicals, helping indoor air stay clean.
Pella Impervia offers quality that stands up and beauty that stands out. Plus, to top things off, they are secured by our limited warranty—one of the best in the industry.2
