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 practically 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 resists conditions from intense heat to freezing cold, making Pella Impervia windows and exterior doors excellent for all climates.

The outstanding insulating properties of our fiberglass replacement windows and patio doors boost your home’s comfort and help save on 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 stays vibrant for a long time—inside and out—with little maintenance. With a wide selection of colors to select, you’ll find windows and patio doors to reflect your home’s design, inside and out. Our environmentally friendly paint process practically eliminates toxic chemicals, helping the air inside your room stay clean.

Pella Impervia features quality that you can rely on 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
