The Pella® Impervia® line blends style with durability in fiberglass windows and patio doors that, as the name implies, are impervious to practically all types of weather.
Impervia’s strength 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 resists conditions from severe heat to freezing cold, making Pella Impervia windows and exterior doors excellent for all regions.
The impressive insulating qualities of our fiberglass replacement windows and patio doors improve your home’s livability and help conserve energy. Optional foam-insulating frames may 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 the long haul—inside and out—with little care. With many colors to choose from, you’ll find windows and patio doors to complement your home’s style, inside and out. Our environmentally friendly paint process practically removes toxic chemicals, helping the air inside your house 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
