Using the garage only as a place to keep your vehicles and other items may prevent you from worrying about the inside temperature as long as you are not storing things that need climate control. So, when you want to start using the garage as a place to exercise, read, or work on projects, you may realize how warm the space gets to the point that you may want to change your mind about using it regularly. It is best to look at how you can minimize the heat in the garage and one method is to replace the windows.
Upgrade the Windows
Although you may be able to replace the windows with exact replacements and get better results because they do not have any wear and tear, you should focus on upgrading them. This means you should get double-pane replacement windows when the ones that you are taking down are single-pane. It may not seem like much of a change, but this alone can account for a noticeable increase in the space's energy efficiency. This will keep the space cooler as well as increase the value of using a portable air conditioner to stay comfortable.
Maximize Airflow Potential
The windows that are in your garage may be functional, but they may not help you much with airflow. Certain types of windows excel in one category but falter in another one. So, if you want to make it easy to open the windows and bring in lots of airflow, you should choose casement windows. These windows are best because you can open them up and avoid the frame getting in the way of creating airflow.
Outfit Them with Window Treatments
It is not uncommon for homeowners to go without window treatments on their garage windows. This is especially true if the windows are within a fenced in yard that makes it hard to peek inside. So, when you do replace them, you should get help from the window installation company to add treatments. An excellent option is to add window tinting to the glass to minimize how much sunlight gets in. You can even go for a minimal tint and then add roller shades for when you want even less light coming through.
Replacing the windows in your garage is just one of several projects that you can take on to improve energy efficiency, but it will provide you with reliable results for several decades.
