Pella® Impervia® Series Windows and Doors

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

Impervia’s durability comes from Duracast®, our special fiberglass composite. It’s one of the toughest and most durable materials obtainable for fiberglass windows and patio doors1. Duracast defends against weather from intense heat to freezing cold, making Pella Impervia windows and exterior doors exceptional for all seasons.

The superior insulating qualities of our fiberglass replacement windows and patio doors enhance your home’s comfort and help reduce energy use. 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 looking great for the long haul—inside and out—with little maintenance. With a wide selection of colors to choose from, you’ll find windows and patio doors to complement your home’s look, inside and out. Our environmentally friendly paint process virtually removes toxic chemicals, helping the air inside your room stay chemical-free.

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