Pella® Impervia® Series Windows and Doors

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

Impervia’s durability comes from Duracast®, our unique fiberglass composite. It’s one of the sturdiest and most durable materials obtainable for fiberglass windows and patio doors1. Duracast stands up to conditions from extreme heat to subzero cold, making Pella Impervia windows and exterior doors great for all seasons.

The impressive insulating qualities of our fiberglass replacement windows and patio doors improve your home’s livability and help save on energy. Optional foam-insulating frames could be added to these ENERGY STAR®-certified windows and patio doors.

Pella Impervia windows and sliding patio doors are delivered prefinished with a factory powder-coat finish that stays vibrant for years—inside and out—with little maintenance. With an array of colors to explore, you’ll find windows and patio doors to match your home’s look, inside and out. Our environmentally friendly paint process virtually gets rid of toxic chemicals, helping the air inside your house stay clean.

Pella Impervia offers quality that stands up 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
