Why Some Homeowners Opt to Have No Windows in Their Garage

Are you still in the process of building your garage? If so, you may be wondering whether or not to get windows added.

In this section, we’ll talk about the reasons why some homeowners don’t like having windows in their garage. Read them for yourself and see if they reflect your mindset towards garage windows as well.

Security Concerns

Windows provide a point of entry into your property and they can be security concerns because of that. Obviously, you can add certain features to keep your windows secure, but are you willing to make that kind of investment?

On top of that, it’s also harder to monitor your garage if it’s detached from your property. Even if someone breaks the windows, you may not hear it right away.

Easier Maintenance

Cleaning up inside the garage can be a chore especially if you use it as your personal workshop. You could end up dealing with bigger messes if your garage has windows. The debris and moisture coming in from the outside will just contribute to the mess.

By keeping the windows shut or not having them at all, you can preserve the garage interior better. Cleaning will be less of a hassle and you’ll be able to get back to your projects faster.

Protecting Their Privacy

As we noted above, the garage is sometimes used as a workshop by many DIYers. If you’re among those DIYers, you probably want that space all to yourself as much as possible. Having windows in your garage may prevent you from enjoying the kind of privacy you’re seeking as you work on projects.

How to Cool Down a Windowless Garage

Let’s now talk about the different ways you can cool down a garage with no windows. Hopefully, you’ll find an option here that works perfectly for your desired workshop setup.

Method 1: Use Fans and a Dehumidifier inside Your Garage

Why does it feel comfortable inside your garage? Is it because the stagnant air there feels heavy and oppressive? That’s often the case if you have humid air circulating inside an enclosed space.

Humid air can be very uncomfortable. It causes your skin to feel sticky and sweaty. Plus, the humidity can also be problematic for those with chronic respiratory issues.

If humid air is the main reason why it’s so uncomfortable inside your garage, then consider getting a dehumidifier. Dehumidifiers can work wonders inside homes and they can do the same thing inside your garage. You can even find portable dehumidifiers so there’s no need to make a big investment here.

Just using a dehumidifier inside your closed garage may not be enough though. You should also put some fans in there so the air circulates better as the dehumidifier processes it. Placing the fans near the garage door works best because that allows them to move the air more effectively.

Method 2: Install a Ceiling Fan

A ceiling fan may not spring to mind immediately as a cooling solution for your closed garage, but it can work. The great thing about ceiling fans is that they are capable of moving plenty of air and that’s exactly what you need.

Since effective air circulation is what you need most from the ceiling fan, you should buy one with four blades. Four-bladed fans are better at moving air than the five-bladed options so they fit better inside your garage. If you can find a ceiling fan with fewer blades, that would be an even better purchase.

Method 3: Get a Portable Air Conditioner

Not all air conditioners have to be installed near a window to work properly. For instance, a portable air conditioner can work just fine even inside an enclosed space.

You can drain the portable air conditioner by letting its hose sneak through the garage door. Leave the hose there as the air conditioner works and enjoy having a more comfortable garage.

Method 4: Change Your Garage’s Paint Scheme

Your garage’s color scheme can have an impact on how hot it gets. Darker colors retain and absorb more heat than their lighter counterparts. Because of how well they retain heat, they can turn your garage into an oven during especially hot days.

Prevent the roof and the walls of your garage from retaining too much heat by switching up your color scheme. Feature lighter colors if you want to improve the comfort level inside your garage.

Method 5: Insulate Your Garage

A lot of people think that insulation is only useful for keeping the house warm, but it does more than that. What insulation does best is regulate temperature. If you already like the temperature inside your home, the insulation you have installed will help maintain that.

You should definitely consider installing insulation if it often gets too warm inside your garage. Insulate different parts of your garage including the door, walls, and ceiling to get the best results.

When choosing insulation, you have to take into account factors such as the type and R-value. Refer to the characteristics of your garage when picking insulation to ensure you make the right purchase.

Method 6: Add a Vent to Your Garage’s Roof

In pursuit of creating a more comfortable closed garage, you can look up at the ceiling for a potential solution. Adding a vent there is a great way to improve the air circulation inside your garage. The vent also gives all the hot air inside that closed space a way out.

If you’re worried that adding a vent to your garage’s roof presents security concerns, you can opt to keep it small. What matters here is that you’re giving the hot air an exit. You can also do more to improve how well the vent regulates the temperature inside your garage. Place an exhaust fan under the vent to greatly improve the air circulation.
