The Pella® Impervia® line blends style with endurance 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 special fiberglass composite. It’s one of the toughest and most reliable materials available 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 boost your home’s livability and help reduce energy use. Optional foam-insulating frames may be included on these ENERGY STAR®-certified windows and patio doors.
Pella Impervia windows and sliding patio doors arrive prefinished with a factory powder-coat finish that stays looking great for the long haul—inside and out—with little upkeep. With many colors to choose from, you’ll find windows and patio doors to complement your home’s design, inside and out. Our environmentally friendly paint process practically eliminates toxic chemicals, helping the air inside your room stay chemical-free.
Pella Impervia brings quality that stands up and beauty that stands out. Also, to top things off, they are supported by our limited warranty—one of the best in the industry.2
