The Pella® Impervia® line couples style with durability 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 unique fiberglass composite. It’s one of the strongest and most durable materials in the market for fiberglass windows and patio doors1. Duracast stands up to weather from extreme heat to subzero cold, making Pella Impervia windows and exterior doors exceptional for all seasons.
The impressive insulating qualities of our fiberglass replacement windows and patio doors improve your home’s coziness and help reduce energy use. 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 looking great 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 design, inside and out. Our environmentally friendly paint process virtually eliminates toxic chemicals, helping the air inside your home stay clean.
Pella Impervia offers quality that stands up and beauty that stands out. And to top things off, they are supported by our limited warranty—one of the most thorough in the industry.2
