The Pella® Impervia® line blends style with endurance in fiberglass windows and patio doors that, as the name implies, are impervious to almost all types of weather.
Impervia’s durability comes from Duracast®, our special fiberglass composite. It’s one of the toughest and most durable materials available for fiberglass windows and patio doors1. Duracast resists weather from extreme heat to subzero cold, making Pella Impervia windows and exterior doors great for all climates.
The impressive insulating qualities of our fiberglass replacement windows and patio doors boost your home’s comfort 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 come prefinished with a factory powder-coat finish that stays looking great for years—inside and out—with little care. With an array of colors to choose from, you’ll find windows and patio doors to match your home’s style, 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 most thorough in the industry.2
