Single-Hung vs. Double-Hung Windows: How to Choose

Single-hung and double-hung windows are commonly used in various home designs and styles. While these window types share some similarities, key differences can impact your home. In comparing single-hung windows to double-hung windows, you can gain insights into these distinctions to help you make the perfect choice for your home.

What is a Single-Hung Window?

A single-hung window, a single-sash window, features a lower operable sash and an upper fixed sash. In this design, the bottom part of the window can be moved up and down, allowing for ventilation, while the upper section remains stationary. This configuration defines the basic operation and structure of a single-hung window.

What is a Double-Hung Window?

A double-hung window, often known as a double-sash window, features two operable sashes that can slide up and down. The two main movable parts of a double-hung window are the top sash and the bottom sash, both capable of opening to provide ventilation. This design allows warm air to escape through the upper sash as heat rises, while cool outside air can flow through the lower sash opening, contributing to increased comfort. This makes double-hung windows an excellent choice, particularly for two-story homes.

Difference Between Single-Hung and Double-Hung Window

Cost

Single-hung windows are generally more budget-friendly than double-hung ones due to their simpler design, fewer moving parts, and lighter frames. The cost of double-hung windows can be up to 75% higher than that of single-hung windows. Additionally, the installation cost may be higher for double-hung windows because of their typically heavier construction. While the price difference per window might not be substantial, it can accumulate significantly, especially if you're replacing windows throughout an entire house.

Ventilation

Both single-hung and double-hung windows offer ventilation options, but the key difference lies in which sashes are operable. In a double-hung window, you can slide open the top sash, the bottom sash, or both, facilitating airflow into and out of your home. On the other hand, with a single-hung window, only the bottom sash is movable, allowing it to slide up for ventilation, while the top sash remains fixed and does not open.

Maintenance and Care

Maintenance and care considerations differ between single-hung and double-hung windows. Double-hung windows are generally easier to maintain because their sashes can tilt inward, allowing you to clean the exterior and interior glass inside your home.

On the other hand, cleaning single-hung windows may require going from inside to outside to clean the glass's interior and exterior. While this may be a minor issue for single-hung windows on the first story of your home, it can become challenging for windows on higher floors. Double-hung windows are a popular choice for upper levels of homes because they offer the convenience of cleaning both sides of the window from inside the house.

Appearance

The primary distinction between single-hung and double-hung windows lies in their operation. In single-hung windows, the top sash is fixed, allowing you to open the window only by moving the bottom sash upward. Conversely, double-hung windows enable you to move both the top and bottom sashes, allowing you to open either or both simultaneously.

Despite the operational differences, single-hung and double-hung windows have an identical appearance from the outside. Some homeowners choose to install double-hung windows on the second story of their home and single-hung windows on the first floor. Both options are available in various styles and come in vinyl, fiberglass, wood, and aluminum frames. While single- and double-hung windows differ in function, their outward appearance remains similar.

Energy efficient

Both single-hung and double-hung windows are designed with energy efficiency in mind, and the choice of frame material adds an extra layer of efficiency. Vinyl and fiberglass windows typically feature multi-chambered frames, which slow the movement of heat, contributing to maintaining warmth in the winter and coolness in the summer.

Fiberglass single-hung and double-hung windows may offer optional insulating foam, enhancing your home's year-round comfort. Wood single- and double-hung windows, a natural insulator, contribute to increased efficiency. Single-hung windows may be slightly more efficient, as they have fewer moving parts, reducing the potential for air infiltration.

Safety

Double-hung windows can pose a security risk if they are not properly shut and secured. The upper sash of a double-hung window may slowly fall if not fully closed, preventing it from locking and potentially allowing intruders to enter. Ensuring double-hung windows are fully closed and locked is crucial to address this security concern.

Single-hung windows may pose a safety risk in households with small children. When the window is open, children can easily reach the bottom sash. If children are small enough to fit through the opening, it can create a hazardous situation.

While both types of windows have their considerations, these risks can be mitigated by taking simple safety precautions, such as ensuring windows are properly closed, locked, and monitored, especially in homes with young children.
