What Are Double Hung Windows?
A double hung window has two operable sashes that slide vertically in the frame. The bottom sash slides up, the top sash slides down, or both can be opened partway to control airflow. Many modern double hung windows also tilt inward, making exterior glass cleaning easier from inside the home.
Benefits of Double Hung Windows
Adjustable Airflow Control
Open the top sash, bottom sash, or both to create flexible ventilation and help warm air escape near the ceiling.
Easy Interior Cleaning
Tilt-in sash options allow safer cleaning from inside the home, especially for second-story windows.
Energy Efficiency
Low-E glass, insulated frames, and quality weatherstripping help reduce drafts and improve comfort.
Versatile Design
Double hung windows fit Colonial, Cape Cod, Craftsman, Victorian, and contemporary homes.
Enhanced Security
Integrated sash locks and modern hardware help secure both operable sashes in the frame.

Double Hung Windows vs. Other Window Types
Double hung windows are a strong all-around choice, but different homes and rooms may call for different styles. Compared with casement windows, double hung windows offer a more traditional look and easier placement near patios or walkways because they do not swing outward. Casement windows typically provide wider ventilation and tighter compression seals.
