The Pella® Impervia® line blends style with durability in fiberglass windows and patio doors that, as the name infers, are impervious to almost all types of weather.
Impervia’s strength comes from Duracast®, our unique fiberglass composite. It’s one of the sturdiest and most durable materials available for fiberglass windows and patio doors1. Duracast stands up to conditions from intense heat to subzero cold, making Pella Impervia windows and exterior doors exceptional for all seasons.
The outstanding insulating qualities of our fiberglass replacement windows and patio doors improve your home’s comfort and help conserve energy. Optional foam-insulating frames can be added to 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 an array of colors to choose from, you’ll find windows and patio doors to complement your home’s look, inside and out. Our environmentally friendly paint process practically removes toxic chemicals, helping the air inside your house stay clean.
Pella Impervia features quality that stands up 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
