The Pella® Impervia® line blends style with durability in fiberglass windows and patio doors that, as the name infers, are impervious to nearly all types of weather.
Impervia’s durability comes from Duracast®, our patented fiberglass composite. It’s one of the toughest and most well-built materials obtainable for fiberglass windows and patio doors1. Duracast stands up to weather from severe heat to subzero cold, making Pella Impervia windows and exterior doors great for all regions.
The outstanding insulating qualities of our fiberglass replacement windows and patio doors enhance your home’s comfort and help save on energy. Optional foam-insulating frames could be installed on 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 a long time—inside and out—with little care. With many colors to select, you’ll find windows and patio doors to complement your home’s style, inside and out. Our environmentally friendly paint process practically gets rid of toxic chemicals, helping the air inside your room stay clean.
Pella Impervia brings quality that stands up and beauty that stands out. Also, to top things off, they are backed by our limited warranty—one of the strongest in the industry.2
