What Are Double-Hung Windows?

Double-hung windows are window styles with two sashes that can be lowered from the top or raised from the bottom to close or open the window. These sashes usually operate independently. The two sashes meet in the middle, where they lock with a latch to shut the window. Unlike the single hung windows, in which you have to clean the upper sash from the outside, double-hung windows are easy to clean as all sashes tilt and therefore can be cleaned from inside your house.

Double-hung windows also ensure excellent ventilation while providing maximum exterior and interior space use since they do not protrude outwards or inwards. As such, you will find this window style in entertainment spaces such as porches and patios.

Double-hung windows are commonly the preferred choice for farmhouse and traditional homes in Ottawa. Incorporating a less detailed grille pattern enhances the conventional aesthetic, giving the window a contemporary detail and allure.

Features and Benefits of Double-Hung Windows

There are many essential features that would make you choose double-hung windows over other window options:

  • Double-hung windows consist of two operable sashes. One of the greatest benefits is excellent ventilation capabilities as both sashes can be opened to allow airflow. The bottom sash allows cool fresh air while the top sash expels warm indoor air. This enhances indoor air quality.
  • Aesthetically appealing – one of the main reasons homeowners choose double-hung windows is their beauty, especially wood double-hung windows. They can be designed in different styles, finishes, sizes, and colours and fit well in modern and traditional homes.
  • Easy to maintain – by design, double-hung windows are engineered for easy maintenance. The two sashes can be tilted for easier cleaning from the inside of your home. Apart from cleaning, the other regular care you need is to inspect the other parts to make sure they are properly lubricated. Thanks to minimal maintenance that any homeowner can do easily, your double-hung windows can serve you for a long time.
  • Safe operation design – unlike other windows that crank out and project outwards, double-hung windows operate differently, saving on space and eliminating the risks of accidents, especially when installed in places with limited space such as walkways and patios. They can be locked when closed and are not easy for intruders to break in.
  • Energy-efficient – double-hung windows are designed with low-E glass with gas fill. This improves its energy efficiency hence helping you to save on energy costs.
