The Pella® Impervia® line couples style with strength in fiberglass windows and patio doors that, as the name infers, are impervious to practically all types of weather.
Impervia’s strength comes from Duracast®, our special fiberglass composite. It’s one of the toughest and most durable materials obtainable for fiberglass windows and patio doors1. Duracast defends against temperatures from severe heat to frigid cold, making Pella Impervia windows and exterior doors great for all regions.
The outstanding insulating features of our fiberglass replacement windows and patio doors enhance your home’s coziness and help save on energy. Optional foam-insulating frames may be installed on these ENERGY STAR®-certified windows and patio doors.
Pella Impervia windows and sliding patio doors arrive prefinished with a factory powder-coat finish that maintains its looks for the long haul—inside and out—with little maintenance. With a wide selection of colors to select, you’ll find windows and patio doors to match your home’s look, inside and out. Our environmentally friendly paint process practically removes toxic chemicals, helping the air inside your home stay healthy.
Pella Impervia offers quality that stands up and beauty that stands out. Also, to top things off, they are secured by our limited warranty—one of the best in the industry.2
