However, their multiple moving parts can eventually lead to issues with energy efficiency and seals. Keep reading to learn more about single-hung windows vs. double-hung windows so you can select the most appropriate solution for your home.


Double-hung windows feature both an upper and lower sash that opens, providing excellent airflow through your home and helping keep it more relaxed in summer and warmer in winter, leading to energy savings. Furthermore, being able to open both upper and lower sashes allows more ventilation options for homeowners and helps prevent moisture build-up in kitchens and bathrooms, reducing indoor allergies.

Double-hung windows feature tilting sashes that make cleaning both panes of glass accessible from within your home, making double-hung an excellent solution for upper-story windows that would otherwise require using ladders or hiring an outside window cleaner. They’re also an excellent way to preserve historical charm while adding modern functionality, often found in Colonial, traditional, or Victorian properties, as they suit an array of design styles well.

As double-hung windows provide more ventilation and ease of cleaning than single-hung ones, they tend to be more costly due to the additional engineering needed to ensure energy efficiency. Furthermore, having more moving parts may increase their potential for leaks, impacting their long-term performance.

Single-hung windows provide reliable and cost-effective ventilation on first floors and other places where simple ventilation may be necessary. They’re an ideal option when considering less costly solutions for basic functionality.

If you want the best of both worlds, combine single-hung windows in less frequented areas with double-hung windows in high-traffic zones of your home or commercial building. This approach provides you with a tailored approach that meets the specific needs of your space while staying within your budget.

Energy Efficiency

Attractive design aside, homeowners also look for energy efficiency when selecting new windows. Both single-hung and double-hung styles feature energy-saving features such as low-E coatings and insulated glass to improve their homes’ performance. However, single-hung windows allow only bottom sash openings, while double-hung styles offer the simultaneous opening of both top and bottom sashes for ventilation and recirculating airflow.

As heat rises, double-hung windows are designed to effectively release hot air from the upper level while simultaneously allowing cool air to enter at the bottom. This helps regulate indoor temperatures throughout the year and keeps your home comfortable.

Double-hung windows may also be more energy-efficient than single-hung windows depending on their size and design, such as by choosing an insulated vinyl or fiberglass frame option, which significantly increases a window’s insulation value. Furthermore, both single-hung and double-hung windows may come equipped with additional energy-efficient features, such as argon gas fills or thermal breaks, to further limit heat transference between rooms.

Poor installation can negatively impact the energy efficiency of both single-hung and double-hung windows, leading to less effective air seals and higher energy costs. Therefore, a qualified contractor must install either window style in your home.

Single-hung windows tend to be cheaper than their double-hung counterparts and can offer several benefits that make them ideal for many homes. Without an operable upper sash to limit ventilation, single-hung windows make cleaning simpler from the inside, as the cleaner can easily be sprayed onto outside glass without needing to reach through a window frame or go outside itself.

Double-hung windows feature two operable sashes that can be opened from either end, providing more ventilation options and making them perfect for sunrooms. Plus, with modern upgrades available for double-hung windows, you can add energy efficiency and functionality for increased efficiency and functionality.

While double-hung windows may be more costly than their single-hung counterparts, their extra costs often outweigh their advantages in terms of energy efficiency and maintenance ease.
