Glass Windows Heat Reduction: 13 Methods to Cool Your Home

Are you worried about summer sun heat increasing the temperature of your entire home? This heat not only causes health issues due to ultraviolet rays but also may cause discoloration overtime items like furniture, colors, flooring and other interior decoration in your home. Don’t worry, I have some proven solutions for this problem.

My home has glass windows and doors all around, and the summer temperature in my region reaches about 40 degrees.

This intense heat was alarming for my family and me. To address this issue, I tried various experiments, and now I’m sharing the most effective methods that have worked for me. These methods will dramatically reduce heat from entering your home or office. Let’s talk about these proven methods:

How to Reduce Sun Heat from Glass Windows:

As you can see in the picture above, my room has a glass window directly facing the sun. This caused the room to catch a lot of sunlight, leading to an increase in temperature. I decided to place blackout curtains (expensive), and the result was much better; the room temperature decreased from 40 degrees to 24 degrees.

This was still not enough to live comfortably in the room. So, I decided to take additional steps and place reflective window films (very cheap) on all the windows and doors. This time, the result was amazing; the temperature dramatically decreased to 21 degrees. Now my entire home is perfect for healthy living.

Remember, applying one method doesn’t guarantee a reduction in sun heat. Other factors also matter, such as ceiling fans, exhaust fans, and proper airflow from the room to the outside.

13 Tips to Reduce the Sun Heat Entering From Glass Windows:

1. Use blinds, shades or curtains to block out the sun heat during the peak hours. Pull them closed before the room gets hot. When its cooler outside you can open the curtains again to let the natural light in. It’s an easy step that will help you to lower the energy bills and your air conditioner would not have to work as hard.
2. Use blackout curtains which are thicker and reduce significant amount of heat that passes through the windows.
3. Try reflective shades they reflect sunlight from the windows and reduce the heat.
4. Use solar control window films these films are amazing and reflect about 80% of the sun’s heat and protect from the ultraviolet rays.
5. Place tinted films on the windows to reduce the sun heat but they slightly make the room darker.
6. Install awnings over the windows to make a shade which will protect from the sun light in the summer.
7. Close the Exterior shutters during the peak hours which will definitely block the sun light.
8. Place Pergolas and Trellises over the windows which will act as a window shade
9. Try reflective materials like aluminum foil or reflective cardboard in windows to reflect sunlight away.
10. Place custom-fit insulated panels in your windows to block heat.
11. If you are planning to replace the windows try low-E glass windows which comes with special coating that reflects infrared light and keep the heat out.
12. Multiple layers of glass with insulating gas between them can also well to reduce heat transfer from outside.
13. Use cellular shades their honeycomb structure traps air, creating an insulating barrier.
