The Pella® Impervia® line couples style with durability in fiberglass windows and patio doors that, as the name infers, are impervious to practically 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 intense heat to freezing cold, making Pella Impervia windows and exterior doors exceptional for all climates.
The superior insulating properties of our fiberglass replacement windows and patio doors enhance comfort and help save on energy. Optional foam-insulating frames can be included 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 stays looking great for the long haul—inside and out—with little care. With many colors to select, you'll find windows and patio doors to complement your clients' styles. Our environmentally friendly paint process virtually removes toxic chemicals, helping indoor air stay chemical-free.
Pella Impervia offers 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 strongest in the industry.2
