The Pella® Impervia® line combines style with endurance in fiberglass windows and patio doors that, as the name infers, are impervious to nearly all types of weather.
Impervia’s strength comes from Duracast®, our patented fiberglass composite. It’s one of the sturdiest and most durable materials obtainable for fiberglass windows and patio doors1. Duracast defends against weather from intense heat to freezing cold, making Pella Impervia windows and exterior doors great for all regions.
The impressive insulating features of our fiberglass replacement windows and patio doors improve your home’s livability and help save on energy. Optional foam-insulating frames may be added to 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 stays looking great for a long time—inside and out—with little upkeep. With a wide selection of colors to explore, you’ll find windows and patio doors to reflect your home’s design, inside and out. Our environmentally friendly paint process virtually removes toxic chemicals, helping the air inside your home stay healthy.
Pella Impervia offers quality that stands up and beauty that stands out. Plus, to top things off, they are supported by our limited warranty—one of the best in the industry.2
