The Pella® Impervia® line combines style with endurance 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 defends against conditions from intense heat to frigid cold, making Pella Impervia windows and exterior doors great for all regions.
The superior insulating properties of our fiberglass replacement windows and patio doors enhance coziness 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 come prefinished with a factory powder-coat finish that stays vibrant for the long haul—inside and out—with little care. With an array of colors to choose from, 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 healthy.
Pella Impervia features 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
