The Pella® Impervia® line couples style with durability in fiberglass windows and patio doors that, as the name implies, are impervious to almost all types of weather.
Impervia’s durability comes from Duracast®, our special fiberglass composite. It’s one of the sturdiest and most well-built materials obtainable for fiberglass windows and patio doors1. Duracast stands up to weather from extreme heat to frigid cold, making Pella Impervia windows and exterior doors excellent for all seasons.
The impressive insulating qualities of our fiberglass replacement windows and patio doors enhance your home’s comfort 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 stays vibrant for years—inside and out—with little care. With a wide selection of colors to explore, you’ll find windows and patio doors to reflect your home’s look, inside and out. Our environmentally friendly paint process virtually removes toxic chemicals, helping the air inside your home stay chemical-free.
Pella Impervia brings quality that stands up and beauty that stands out. Also, to top things off, they are backed by our limited warranty—one of the most thorough in the industry.2
