Nothing is worse than inescapable summer heat.

You can try to hide in your house and blast the A/C, but uh oh… it’s creeping through the windows! Oh no, it’s actually on the windows! Yikes! 

During a hot day, your windows can bring in a ton of heat. If you don’t have an air conditioner to keep the temperature down, this can quickly turn your home into an oven.

Luckily, there are ways to insulate your windows to keep the heat out. There are also ways to keep your room nice and cool without an A/C. Combine all these methods and you may never be hot again!

So, let’s get to it: let’s beat the heat!

10 Quick Ways To Insulate Your Windows 

Try these tips, either one at a time or all together, and there’ll be a dramatic change in the temperature.

These tips will also help you keep your electric bill down. Let’s get started.

  1. Weatherstrip. This tip has the benefit of being good for both summers and winters. In the summer, you’ll be able to keep the cool air in and the hot air out. In the winter, you’ll be able to keep the warm air in and the cold air out. It’s a two-in-one tip!
  2. Bubble wrap. Although you may get some weird looks, putting bubble wrap on your windows will keep them cool. You can use tape to put them up, but you can also use a bit of water. Spray your windows and put the bubble-side against the surface. It’ll stick easily and stay there until you need to take it off or want to pop them. Pop pop!
  3. White towels. This may also get you strange side-glances, but it’s yet another cheap way to keep your windows cool. Place them on your curtain rod and let them reflect the sun’s heat.
  4. Aluminum foil. Okay, I promise that this is the last strange tip, but it does work! By placing the shiny side to the window, you’ll also reflect the heat. However, unlike the previous two methods, this one requires taping. So, when you’re putting on the foil, be careful not to tape anything that it’ll eventually rip off. For this reason, you’ll want to avoid placing it on paint and plaster.
  5. Cellular shades. If you’d like a more attractive-looking method, cell shades are perfect. They have built-in pockets that can trap both hot and cold air. This prevents any extreme and sudden changes in the room’s temperature. This can be useful for both the summers and the winters.
  6. Insulated shutters This is a more expensive approach, but they’ll do the trick. They’re extremely thick, which is a perfect barrier against the heat. Plus, they look super stylish.
  7. High-reflectivity window film. This product’s name is pretty self-explanatory. By placing this thin film over your window, sunlight will bounce right off it. Not only that, but it can also prevent sunlight damage, provide privacy, and fortify the window’s durability. However, there are downsides to using window film. Your neighbours may not appreciate the reflected sunlight glare and it can shine away much-needed heat in the winter. Be sure that you don’t disturb anyone before putting the film up and take it off during the cold days.
  8. A draft snake. Luckily, these snakes are nothing like the real animal. They can be pretty cute and easily made, so if you were also looking for a new DIY project, this is the perfect option for you. You will need a tube of fabric, which you can either sew together or use a sock or a sweater sleeve. Once you have it, you will have to fill it with insulation material, which can be cotton, newspapers, or rice. Then ta-da! You’ll have a decorative fabric snake to put on your windowsill. You can also put it against the bottom of your door, and it’ll prevent any hot air from sneaking in.
  9. Blackout blinds. If you’re so hot and you don’t even want to see the sun anymore, blackout blinds are the way to go. They will block any sunlight from getting in and will keep your room completely dark. This has the added benefit that it’ll help with your sleep, especially if you’re a light sleeper or if you hate getting the morning sunshine in your eyes.
  10. Get rid of them altogether and put in energy-efficient windows! If you’ve tried every one of these tips and you still find yourself melting away, you might have to break out the wallet.

    By getting energy-efficient windows, you’ll keep the interior air in and the exterior air out. It’s an expensive solution, but it’ll be a long-term investment. 

10 Tips to Stay Cool Without an Air Conditioner

There is already a fantastic article that already covers over 70 tips to keep cool without an air conditioner. To save you a click, here are ten tips that’ll keep your home heat-free. 

  1. Have your ceiling fans rotate counter-clockwise. When they’re set to rotate counter-clockwise, ceiling fans push air downwards. This will keep you cool, but if you ever get too cold, set the fan to rotate clockwise. It will circulate the air around the room rather than simply below.
  2. Get a dehumidifier. Nothing is worse than a hot and humid summer day. When there’s more humidity in the air, it’s harder for your sweat to evaporate and keep you cool. By using a dehumidifier, it’ll remove the excess moisture in the air and help you sweat better.
  3. Replace your incandescent lights. Not only will this lower your energy bill, but it’ll also lower the temperature. An incandescent bulb wastes 90% of its energy and emits it as heat. By switching your light bulbs to LED, you’ll save energy and stay cool.
  4. Unplug everything. If you’re not using it, unplug it! Even a powered-off electronic that’s plugged in will produce heat.
  5. Close the doors to unused rooms. If you’re not using it, close it! Keep the cool air where you need it and prevent it from going into empty rooms.
  6. Take your fan to the next level. Get a bowl of ice and place it in front of your fan. By doing this, you’ll have a super cool and super misty breeze. If you don’t have a lot of ice cubes to spare, you can also use something that is just as cold and place it in a bowl. Worse comes to worst, you can also use water, but it won’t be as effective.
  7. Change your sheets and fabrics to cotton. Cotton breathes easier than other fabrics, so swap out your clothes and blankets. You’ll be able to keep cool and avoid suffering from heatstroke.
  8. Turn on your exhaust fans. When you cook or take a shower, you should keep the exhaust fan on. However, even if you’re not using the kitchen or the bathroom, you should still keep them on. Just like how they suck in steam and spit it out, they’ll also pull in hot air and replace it with cool air.
  9. Stay close to the ground. If you have a basement or access to a lower level, it’ll be much cooler than any room up top. Hot air rises so the further down you are, the less heat you’ll encounter. You can also sleep old-school and sleep on the ground, with or without your mattress.
  10. Put off your household chores until night. Hooray! Finally, a legitimate reason for procrastination! But in all seriousness, it is best to do most of your chores when the day becomes cooler. Appliances such as dryers and washers emit a lot of heat, so if you can, try postponing your chores to a later time. Just don’t forget to actually do them!

Conclusion

Before you go and buy an expensive and heavy air conditioner, try out these tips to insulate your windows against summer heat.

You might be surprised at how much heat that an uninsulated window can bring and how cool you can get if you do something about it. And you might also be more grateful for the fact that you’ll be keeping your electricity bill down.

Remember, you can combine any of these tips together. So, if you find that one of them isn’t very effective, try it with another tip! Eventually, you’ll get the temperature down and beat that heat!
