The Pella® Impervia® line couples style with durability in fiberglass windows and patio doors that, as the name infers, are impervious to almost 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 intense heat to subzero cold, making Pella Impervia windows and exterior doors excellent for all seasons.
The impressive insulating properties of our fiberglass replacement windows and patio doors improve coziness and help save on energy. Optional foam-insulating frames can be added to these ENERGY STAR®-certified windows and patio doors.
Pella® Impervia® windows and sliding patio doors arrive prefinished with a factory powder-coat finish that stays vibrant for years—inside and out—with little upkeep. With a wide selection of colors to explore, you'll find windows and patio doors to match your clients' styles. Our environmentally friendly paint process practically eliminates toxic chemicals, helping indoor air stay healthy.
Pella Impervia brings quality that you can rely on and beauty that stands out. Also, to top things off, they are supported by our limited warranty—one of the most thorough in the industry.2
