Pella® 250 Series Vinyl Double-Hung Window

Energy efficiency, reduced noise and curb appeal are among the key benefits of replacement windows.

The difference between single-hung and double-hung windows is the number of sashes that move. A single-hung window has one fixed, or non-operable, sash and one operable, or moveable, sash. A double-hung window has two operable, or moveable, sashes.

When cleaning double-hung windows, tilting the sashes in makes it easy to clean exterior surfaces from the interior of your home. Clean the top sash first, starting with the exterior and followed by the interior, and then repeat the same process on the lower sash. Watch this step-by-step video to learn more about window washing for easy-clean double-hung windows.

It depends what benefits are most important to you. Pella's fiberglass is the strongest material for windows, offering a low-maintenance and durable finish.⁹ If you're after a window that's tested to extremes, Pella's fiberglass windows are the way to go. Vinyl windows are easy to care for, energy efficient and budget friendly. Pella’s unique vinyl formula is performance-tested for excellent weathering, durability and color retention.
