Pella® Impervia® Series Windows and Doors

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 toughness comes from Duracast®, our patented fiberglass composite. It’s one of the toughest and most reliable materials in the market for fiberglass windows and patio doors1. Duracast defends against weather from severe heat to freezing cold, making Pella Impervia windows and exterior doors exceptional for all seasons.

The outstanding 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 added to these ENERGY STAR®-certified windows and patio doors.

Pella Impervia windows and sliding patio doors come prefinished with a factory powder-coat finish that stays looking great for the long haul—inside and out—with little care. With a wide selection of colors to explore, you’ll find windows and patio doors to complement your home’s design, inside and out. Our environmentally friendly paint process essentially gets rid of toxic chemicals, helping the air inside your house stay healthy.

Pella Impervia brings quality that you can rely on and beauty that stands out. Plus, to top things off, they are backed by our limited warranty—one of the most thorough in the industry.2
