Pella® Impervia® Fiberglass Picture Window

Pella’s proprietary fiberglass is the strongest material for windows, engineered for lasting durability.⁶¹ Our exclusive fiberglass will never rot or corrode, and it resists dents, bends and breaks.

Picture windows are extremely energy efficient given that they do not open and close. Also highly efficient are windows with dual- and triple-pane glass as they improve insulating properties and help reduce thermal transfer.

Picture windows do not operate, so they are common in areas that are out of reach. They add natural light and increase curb appeal in places where you don't need the window to ventilate, such as tall foyers and stairways.

There are many factors that affect the actual long-term performance, appearance and functionality of fiberglass windows, but Pella's fiberglass windows are designed for a lifetime of everyday use.
