The Pella® Impervia® line combines style with strength in fiberglass windows and patio doors that, as the name suggests, are impervious to almost all types of weather.
Impervia’s strength comes from Duracast®, our unique fiberglass composite. It’s one of the toughest and most durable materials in the market for fiberglass windows and patio doors1. Duracast resists conditions from severe heat to freezing cold, making Pella Impervia windows and exterior doors exceptional for all climates.
The superior insulating qualities of our fiberglass replacement windows and patio doors enhance your home’s coziness and help reduce energy use. Optional foam-insulating frames can be added to 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 years—inside and out—with little care. With many colors to choose from, you’ll find windows and patio doors to match your home’s design, inside and out. Our environmentally friendly paint process essentially gets rid of toxic chemicals, helping the air inside your house stay healthy.
Pella Impervia offers quality that you can count on and beauty that stands out. And to top things off, they are secured by our limited warranty—one of the most thorough in the industry.2
