Double Hung Windows
They fit well in bedrooms, living rooms, and on upper floors. The design has been around a long time because it’s simple and it works well.
How Double Hung Windows Work
Each sash moves on tracks inside the frame. Both sashes can also tilt inward, so you can clean the outside glass from inside your house. That’s a big reason people use them on second floors. When they’re closed, the sashes press into the frame to help block air leaks and water.
They don’t stick out or swing open, so they don’t get in the way of walkways or furniture.
Frequently Asked Questions
How do double-hung windows operate compared to a single-hung window?
Unlike single-hung windows, where only the bottom sash moves, a double-hung window has two operable sashes that slide up and down. This allows you to open the top, the bottom, or both at the same time for customized airflow. Additionally, both sashes on our double hung models tilt inward, making it incredibly easy to clean the exterior glass from the safety of your home’s interior
Why are double-hung windows a good choice for second-story rooms?
Double-hung windows are the preferred choice for upper floors because of their tilt-in cleaning feature. You no longer need a ladder to clean the outside of your second-story windows.
Are double-hung windows secure and energy-efficient?
Yes. Our double-hung windows feature an integral interlock system with triple weatherstripping to seal the sashes tightly against air and water infiltration. For security, they come equipped with dual vent locks, which allow you to keep the window slightly open for ventilation while deterring forced entry.
