The Pella® Impervia® line combines style with strength in fiberglass windows and patio doors that, as the name implies, are impervious to practically all types of weather.
Impervia’s strength comes from Duracast®, our unique fiberglass composite. It’s one of the sturdiest and most durable materials in the market for fiberglass windows and patio doors1. Duracast stands up to weather from intense heat to freezing cold, making Pella Impervia windows and exterior doors great for all climates.
The superior insulating features of our fiberglass replacement windows and patio doors enhance 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 stays vibrant for the long haul—inside and out—with little upkeep. With many colors to explore, you’ll find windows and patio doors to match your home’s design, inside and out. Our environmentally friendly paint process virtually gets rid of toxic chemicals, helping the air inside your home stay chemical-free.
Pella Impervia brings quality that you can count on and beauty that stands out. Also, to top things off, they are supported by our limited warranty—one of the strongest in the industry.2
