The Pella® Impervia® line couples style with strength in fiberglass windows and patio doors that, as the name suggests, are impervious to nearly all types of weather.
Impervia’s strength comes from Duracast®, our patented fiberglass composite. It’s one of the toughest and most durable materials in the market for fiberglass windows and patio doors1. Duracast stands up to temperatures from extreme heat to freezing cold, making Pella Impervia windows and exterior doors excellent for all regions.
The outstanding insulating properties of our fiberglass replacement windows and patio doors improve 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 come prefinished with a factory powder-coat finish that stays vibrant for the long haul—inside and out—with little care. With a wide selection of colors to explore, you’ll find windows and patio doors to reflect your home’s style, inside and out. Our environmentally friendly paint process essentially gets rid of toxic chemicals, helping the air inside your home stay clean.
Pella Impervia offers quality that stands up and beauty that stands out. Plus, to top things off, they are supported by our limited warranty—one of the strongest in the industry.2
