Pella® Impervia® Series Windows and Doors

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

Impervia’s toughness comes from Duracast®, our special fiberglass composite. It’s one of the strongest and most reliable materials available for fiberglass windows and patio doors1. Duracast resists conditions from intense heat to frigid cold, making Pella Impervia windows and exterior doors excellent for all climates.

The impressive insulating properties of our fiberglass replacement windows and patio doors improve your home’s livability and help conserve energy. Optional foam-insulating frames can be included on 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 years—inside and out—with little maintenance. With many colors to select, you’ll find windows and patio doors to reflect your home’s look, inside and out. Our environmentally friendly paint process virtually gets rid of toxic chemicals, helping the air inside your home stay healthy.

Pella Impervia offers quality that stands up and beauty that stands out. Also, to top things off, they are backed by our limited warranty—one of the best in the industry.2
