The Pella® Impervia® line couples style with strength in fiberglass windows and patio doors that, as the name infers, are impervious to almost all types of weather.
Impervia’s durability comes from Duracast®, our special fiberglass composite. It’s one of the strongest and most reliable materials in the market for fiberglass windows and patio doors1. Duracast resists conditions from severe heat to subzero cold, making Pella Impervia windows and exterior doors great for all climates.
The superior insulating properties 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 stays looking great for years—inside and out—with little care. With many colors to explore, you’ll find windows and patio doors to match your home’s look, inside and out. Our environmentally friendly paint process virtually gets rid of toxic chemicals, helping the air inside your room stay clean.
Pella Impervia brings quality that you can count on and beauty that stands out. Plus, to top things off, they are backed by our limited warranty—one of the best in the industry.2
