The Pella® Impervia® line couples style with durability in fiberglass windows and patio doors that, as the name suggests, are impervious to practically all types of weather.
Impervia’s strength comes from Duracast®, our unique fiberglass composite. It’s one of the toughest and most reliable materials obtainable for fiberglass windows and patio doors1. Duracast stands up to weather from intense heat to frigid cold, making Pella Impervia windows and exterior doors exceptional for all climates.
The outstanding insulating qualities of our fiberglass replacement windows and patio doors improve your home’s comfort and help conserve 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 a long time—inside and out—with little upkeep. With many colors to explore, you’ll find windows and patio doors to reflect your home’s design, inside and out. Our environmentally friendly paint process essentially eliminates toxic chemicals, helping the air inside your home stay clean.
