Single Hung Window Vs Double Hung Windows | What's The Difference?

Single-hung and double-hung windows are common types of windows found in homes, apartments, and commercial buildings. While both types serve the same purpose of providing natural light and ventilation, they differ significantly in terms of design, functionality, and cost.

Understanding the differences between single-hung and double-hung windows can help homeowners make an informed decision when choosing the right type of window for their home.

Single-hung windows have been around for a long time and are a popular choice for homeowners. They feature two sashes, with the bottom sash being operable and the top sash being fixed.

In contrast, double-hung windows have two operable sashes that slide up and down, allowing for greater control over ventilation and airflow. The design and functionality of these windows can significantly impact the amount of light, air, and energy that enters a home, as well as the ease of maintenance and cleaning.

This article will explore the key differences between single-hung and double-hung windows, their benefits, and which option may be best suited for different types of homes and buildings.
