The Pella® Impervia® line combines 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 stands up to weather from severe heat to freezing cold, making Pella Impervia windows and exterior doors exceptional for all seasons.
The impressive insulating qualities of our fiberglass replacement windows and patio doors enhance coziness and help save on energy. Optional foam-insulating frames can be installed on these ENERGY STAR®-certified windows and patio doors.
Pella® Impervia® windows and sliding patio doors come prefinished with a factory powder-coat finish that stays looking great for the long haul—inside and out—with little care. With a wide selection of colors to explore, you'll find windows and patio doors to match your clients' tastes. Our environmentally friendly paint process practically gets rid of toxic chemicals, helping indoor air stay healthy.
Pella Impervia brings quality that you can count on and beauty that stands out. Plus, to top things off, they are backed by our limited warranty—one of the most thorough in the industry.2
