Pella® Impervia® Series Windows and Doors

The Pella® Impervia® line combines style with strength in fiberglass windows and patio doors that, as the name infers, are impervious to practically all types of weather.

Impervia’s toughness comes from Duracast®, our special fiberglass composite. It’s one of the sturdiest and most reliable materials available for fiberglass windows and patio doors1. Duracast defends against temperatures from extreme heat to frigid cold, making Pella Impervia windows and exterior doors excellent for all seasons.

The impressive insulating features of our fiberglass replacement windows and patio doors improve your home’s livability and help conserve 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 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 complement your home’s look, inside and out. Our environmentally friendly paint process essentially removes toxic chemicals, helping the air inside your home stay chemical-free.

Pella Impervia features quality that stands up and beauty that stands out. And to top things off, they are secured by our limited warranty—one of the most thorough in the industry.2
