Double-Hung Windows


Double-hung windows are found in many homes across the nation. They make maintenance simple and visually pleasing, and their simple cleaning needs make them ideal for many architectural styles. The best guide to finding Energy Star windows.

Double-hung windows feature an innovative design that allows fresh air to enter from below while warm air escapes through the top—an effective ventilation method during warmer months.


Double-hung windows feature two operable sashes that slide vertically, allowing airflow through both when they’re opened compared to single-hung windows and providing superior ventilation compared to their single counterparts. In addition, double-hungs are easy to clean and offer more design choices than their single-hung counterparts, making them a popular choice in homes featuring traditional or colonial architecture, while modern homes with craftsman or Victorian aesthetics may also utilize them.

Double-hung windows offer numerous ventilation benefits that make them an excellent addition to many homes. Opening both sashes allows cool air from outside to enter while warm air exits, helping lower utility bills and greater comfort while simultaneously saving on heating/cooling bills. They are especially beneficial in warmer climates like Maryland, Virginia, and other mid-Atlantic states, where extreme temperatures often force homes’ HVAC systems beyond capacity.

Double-hung windows offer ventilation benefits and are energy efficient. Their flexible opening options make them an excellent way to control home temperatures—just open one sash while closing another, both at the same time or just one! With such control over temperature management options available to them, double-hung windows make an intelligent investment for any homeowner.

Weatherstripping and low-E glass are also critical elements in energy-saving double-hung windows. They help reduce heat transfer while improving insulation and saving on operating costs. They’re an economical and eco-friendly choice for homeowners.

Double-hung windows feature tilting sashes that provide easy access to both sides of the glass for cleaning, which makes these windows ideal for higher-level buildings where reaching exterior single-hung windows without using ladders may be challenging. In addition, these double-hung windows are safe for children as their lower sash can remain closed, and the upper sash can be lowered to ground level so as to prevent climbing over the window sill and falling out of their house.


Double-hung windows have long been a top choice among homeowners seeking a balance between classic aesthetics and practicality. Their operating style allows both upper and lower window panes to open, making it simple to let in fresh air or release strong smells from within a room. Furthermore, this design helps regulate sunlight entering each room for customized illumination and ventilation levels.

Maintaining double-hung windows with the necessary tools and supplies is simple. Scheduled cleaning and maintenance sessions will help your double-hungs stay in top condition for years, improving their performance while maintaining their attractive appearance.

At least twice annually, you should aim to clean your double-hung windows using the same basic steps you would for any other window type. First, prepare your cleaning supplies and clear away any dust or debris that has accumulated on either frame or glass surfaces. Next, open both sashes of windows for proper cleaning before drying and polishing them afterwards to prevent moisture build-up and protect the paint finish against potential damage.

Modern double-hung windows often come equipped with tilt-in features that enable their window sashes to tilt inward for easy cleaning of their exterior surfaces. This is especially helpful in second—or third-story homes, where accessing and cleaning them is quicker without needing a ladder.

For double-hung windows to tilt in, first locate and release any tilt latches on top of the bottom sash. Then, raise and open the bottom sash until the window is flush with the frame—this may take six to eight inches of raising or opening time.

Once your double-hung windows are open, you can begin cleaning their exterior glass by pulling inward the tilt hatches of both sashes—lower and upper sash! Repeat this process until both sides of the window have been cleaned thoroughly before closing them back up securely and snapping them back into place.

Energy Efficiency

Double-hung windows can be opened both at the top and bottom for optimal air circulation throughout your home and to help vent out odors in rooms such as bathrooms and kitchens. They’re particularly beneficial during warmer seasons when air conditioning costs can become more costly to run. Plus, double-hung windows offer greater energy efficiency as their tight seal prevents air leakage, leading to reduced utility bills for homeowners.

Double-hung windows feature frames made from fiberglass or vinyl that act as excellent insulators and typically incorporate warm-edge spacer bars to further reduce heat transfer. Thanks to these features, many double-hung windows have earned the ENERGY STAR label and qualify for tax credits, making them an excellent option for homes wishing to maximize energy efficiency.

Some may argue that double-hung windows are more energy-efficient, but this depends on a range of factors. Casement windows with cranks have more moving parts than double-hung ones and may thus be less energy-efficient overall. Furthermore, energy ratings depend on how homeowners use and maintain their windows.

An additional factor to consider when purchasing windows is whether the homeowner prefers dual-glazed or triple-glazed models, as this will determine their energy-efficiency rating. While triple-glazed models may seem costly at first, remember that investing in them will significantly boost the energy-efficiency ratings of your window(s).

At the end of the day, it is up to each homeowner to determine which features are most essential to their home and budget. Some prioritize energy efficiency, while others favor the aesthetic and ventilation benefits offered by double-hung windows.

Double-hung windows feature two operable sashes, allowing homeowners to open both top and bottom sashes independently for better airflow and circulation. In addition to bringing in fresh air, this allows for improved cleaning and keeps interior temperatures cooler during warmer months. Sashes slide past each other within their frame for ease of cleaning as they help prevent drafts while eliminating drafts.

Double-hung windows are also great options for homes with children since you can latch the lower window and open only its upper half at once, keeping small hands out of reach of small hands. As any manual operation window type would, double hungs pose potential safety threats if not locked correctly; left open, their upper sashes may fall inward over time and expose your home to intruders.

To prevent this from happening, it’s essential that double-hung windows are checked regularly for proper operation and closure. To do so, measure each sash diagonal and ensure it lines up with both sill and jamb; if they don’t line up perfectly, you may use wood shims until everything lines up, then simply tighten all screws back up!

Another safety feature of double-hung windows is their non-protrusion design. This makes them suitable for spaces with limited exterior space (such as front porches where crank-out windows would protrude too far) while offering a more traditional look, making them popular among those seeking timeless designs.
