The Pella® Impervia® line couples style with endurance in fiberglass windows and patio doors that, as the name implies, are impervious to almost all types of weather.
Impervia’s strength comes from Duracast®, our patented fiberglass composite. It’s one of the toughest and most durable materials available for fiberglass windows and patio doors1. Duracast defends against weather from intense heat to subzero cold, making Pella Impervia windows and exterior doors exceptional for all regions.
The outstanding insulating features of our fiberglass replacement windows and patio doors improve your home’s livability and help save on energy. Optional foam-insulating frames could 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 maintains its looks for years—inside and out—with little care. With a wide selection of colors to explore, you’ll find windows and patio doors to complement 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 healthy.
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
