Pella® Impervia® Series Windows and Doors

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

Impervia’s toughness comes from Duracast®, our unique fiberglass composite. It’s one of the toughest and most reliable materials available for fiberglass windows and patio doors1. Duracast resists conditions from intense heat to subzero 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 livability and help conserve energy. Optional foam-insulating frames can 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 vibrant for the long haul—inside and out—with little care. With an array of colors to explore, you’ll find windows and patio doors to match your home’s design, inside and out. Our environmentally friendly paint process practically eliminates toxic chemicals, helping the air inside your house stay chemical-free.

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