When choosing the right windows for your home, functionality, style, and efficiency all matter. Among the most popular options are single-hung and double-hung windows—classic designs that have stood the test of time while offering modern performance benefits.

But what’s the difference between the two, and which one should you choose? Let’s break it down with insights from San Mateo Glass and Mirror, your trusted local glass and window experts.

What Are Single-Hung Windows?

Single-hung windows feature two sashes (panels), but only the bottom sash moves. The top sash remains fixed in place.

Key Features:

• Bottom sash slides vertically

• Top sash stays stationary

• Simple and cost-effective design

• Traditional aesthetic

Single-hung windows are a great option for homeowners who want a classic look at a more affordable price point.

What Are Double-Hung Windows?

Double-hung windows also have two sashes, but both the top and bottom sashes are operable. This allows for greater flexibility in ventilation and cleaning.

Key Features:

• Both sashes move up and down

• Improved airflow and ventilation

• Easier cleaning (especially tilt-in designs)

• Enhanced functionality

Double-hung windows are ideal for homeowners who want convenience, versatility, and better air circulation.

Single-Hung vs. Double-Hung Windows: Key Differences

1. Ventilation

• Single-hung: Limited airflow since only the bottom sash opens.

• Double-hung: Better ventilation because both sashes can open.

2. Ease of Maintenance

• Single-hung: Slightly harder to clean the exterior glass.

• Double-hung: Easier cleaning with tilt-in sashes.

3. Cost

• Single-hung: More budget-friendly.

• Double-hung: Higher cost due to added functionality.

4. Energy Efficiency

Both window types can be energy-efficient when paired with modern glass options like double-pane or Low-E glass. Proper installation plays a major role in performance.

5. Style and Versatility

Both single-hung and double-hung windows complement traditional and modern home designs, making them versatile choices for various architectural styles.

Benefits of Single and Double-Hung Windows

These windows offer a timeless look that works well in both residential and commercial properties.
