The Pella® Impervia® line blends style with endurance in fiberglass windows and patio doors that, as the name implies, are impervious to practically all types of weather.
Impervia’s toughness comes from Duracast®, our patented fiberglass composite. It’s one of the sturdiest and most well-built materials available for fiberglass windows and patio doors1. Duracast resists weather from severe heat to subzero cold, making Pella Impervia windows and exterior doors excellent for all seasons.
The outstanding insulating features of our fiberglass replacement windows and patio doors improve your home’s comfort and help conserve energy. Optional foam-insulating frames may 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 the long haul—inside and out—with little upkeep. With an array of colors to choose from, you’ll find windows and patio doors to match your home’s design, inside and out. Our environmentally friendly paint process practically removes toxic chemicals, helping the air inside your home stay chemical-free.
Pella Impervia offers quality that you can rely on and beauty that stands out. Also, to top things off, they are backed by our limited warranty—one of the best in the industry.2
