Double-Hung Windows

Double-hung windows have two sashes that both slide up and down. Open the upper sash to vent heat or the lower sash to bring air in. Open both for balanced airflow.
They fit just about anywhere—bedrooms, living rooms, second-story spaces. Traditional enough for older homes; neutral enough for newer builds.
Vinyl construction keeps maintenance low. Sliding-type windows generally have slightly higher air leakage than hinged styles; quality and installation still matter.
This page covers what double-hung windows are, where they fit best, comparisons to other styles, energy features, and basic operation.

Bedrooms & Traditional Facades
Classic vertical lines suit colonial/farmhouse styles. Use top and bottom sashes for balanced airflow.

First-Floor Living Areas
Pair with picture windows—light from the center, ventilation from the sides. Works near furniture; no inward/outward swing.

Second-Story Locations
Tilt-in cleaning (when included) reduces ladder use for upper floors and hard-to-reach windows.

When Other Styles Might Work Better
Tight exterior clearance: sliders offer wide openings with a horizontal look. Lowest air leakage & max ventilation: hinged casements/awnings typically outperform.

Double-Hung vs Single-Hung
Double-hung = better ventilation + easier cleaning; single-hung = simpler mechanism and typically lower cost.

Double-Hung vs Casement
Double-hung keeps a traditional look; casement usually seals tighter and opens fully for maximum airflow.

Double-Hung vs Slider
Both suit tight spaces. Vertical vs horizontal operation; similar air-leakage profile as sliding types.
