Pella ® Impervia ® Advanced alternative. Lasting value.
Pella Impervia windows and patio doors combine the beauty you expect from Pella with the durability to be virtually impervious to all weather conditions. They're made of Pella's patented fiberglass composite called Duracast® – the strongest, most durable material available in windows and patio doors.* That means Pella Impervia products can take almost anything nature or your family can dish out. Including extremely hot or cold weather, impacts, scratches, sea air – even damaging UV rays. Plus, they're low-maintenance and incredibly energy efficient. But the real strength of Pella Impervia windows and doors is their value. Duracast is nine times stronger than vinyl.* And competitively priced.
*In testing performed in accordance with ASTM testing standards, Pella's Duracast has displayed superior performance in strength, ability to withstand extreme heat and cold, and resistance to dents and scratches.
