The Pella® Impervia® line combines style with endurance 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 resists conditions from extreme heat to subzero cold, making Pella Impervia windows and exterior doors great for all seasons.
The impressive insulating qualities of our fiberglass replacement windows and patio doors boost comfort 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 are delivered 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' styles. Our environmentally friendly paint process virtually removes toxic chemicals, helping indoor air stay healthy.
Pella Impervia brings quality that you can count on and beauty that stands out. And to top things off, they are secured by our limited warranty—one of the most thorough in the industry.2
