Made with Duracast® -- the strongest, most durable material available in windows and doors*
Duracast is nine times stronger than vinyl and twice as strong as aluminum.* It withstands extreme weather ensuring years of outstanding performance. Plus, it’s more scratch-resistant, impact-resistant and thermally stable than conventional fiberglass, vinyl or aluminum.
Offers the Thermal Efficiency of Wood
The excellent insulating properties of Duracast® help make Pella Impervia windows and doors highly energy-efficient. Aluminum is a natural conductor and can allow more heat and cold to penetrate the window.
Priced Competitively With Vinyl
Pella® Impervia® windows and patio doors are cost-effective for projects in all price ranges. Their strength, superior durability, attractive appearance and ease of installation offer a clear advantage over vinyl, aluminum and conventional fiberglass. Just imagine - Pella quality at a competitive price.
