What’s the Difference?

When it comes to double hung windows, the two sashes within the frame are both operable. They can be moved either up and down, or tilt outwards or inwards on an axis.

Similar to double hung windows, single hung replacement windows in Ottawa have two sashes. However, what differentiates this style from double hung, is that the top sash is fixed in place so it cannot move, whereas the bottom sash is still operable. In some cases, you may even be able to install a single hung window with the unique option to include decorative a geometric shape in the top sash.

Typically, single hung windows are the standard window design that is used in modern home, apartment, and office construction.

Pros and Cons of a Double Hung Window


Double hung replacement windows in Ottawa provide the opportunity for easy cleaning. Both sashes can be accessed from the inside because of their ability to open and close, rather than just the bottom sash.

This particular feature also allows for much better airflow and ventilation than the single hung window design. When there is poor ventilation, the air in your home can become stagnant. This can lead to higher concentrations of contaminants as well as higher moisture levels. Proper ventilation is important and allows you to maintain much higher indoor air quality, improving the health and comfort of you and your family.


Unfortunately, double hung windows come with a more expensive initial cost than single hung. However, there is one thing you should keep in mind if you are worried about the cost of double hung replacement windows in Ottawa. There are many utility companies that will offer you a rebate if you install energy-efficient windows in your home. This can significantly reduce the amount of money you will be spending on your home improvement project.

Pros and Cons of a Single Hung Window


It is roughly 10 to 20 percent less expensive to install single hung replacement windows in Ottawa over double hung. This may not seem like a big difference when replacing only one or two windows in your home, but if you are planning on completing a much bigger remodel, it can definitely add up. If you are on a tighter budget, single hung windows might be your best option.

Additionally, since a single hung replacement window in Ottawa only has one operable sash, it has the potential to provide stronger energy efficiency than a double hung window.


Conversely, since single hung windows do have only one operable sash, they will allow for less ventilation in your home. Some rooms will simply require more ventilation, such as the bathroom. When there is not enough ventilation, moisture levels can raise, resulting in the growth of mildew and unwanted odours. Knowing which window is the right fit for a certain space will make a world of a difference in the long run.

The other con is that single hung windows are significantly more difficult to clean than double hung. Specifically, the exterior of the top sash is hard to give a regular cleaning as it is not movable. This means that anyone who is installing single hung windows on an upper floor of their home may require the help of a professional window cleaning service.

So, Which One?

Both double hung and single hung windows come with their own set of benefits and drawbacks. Ultimately, which one you choose will depend entirely on your preference as well as the space you are having them installed in.
