A resident of Arizona, United States, went viral on TikTok after sharing a simple trick to reduce heat inside the car: using aluminum foil or a sunshade on the sunroof.
In the video, he shows a protective layer made of aluminum installed on the sunroof to block sunlight and help keep the vehicle interior cooler. According to him, the method has been tested on several cars with excellent results, attracting attention from many users living in hot climate regions.
Other users have shared similar hacks, such as a woman who applied the technique to her home windows and a blogger who created a thermal insulator for the car’s glass roof using homemade materials. The latter even measured the temperature difference with an infrared thermometer and found that the internal roof temperature dropped by approximately 17°C, making the driving experience much more pleasant.
Experts and sources such as Garage Living point out that aluminum does reflect heat, but there are more efficient options such as professional sunshades, window films, and UV-absorbing materials. However, the homemade trick is inexpensive and can work well in emergencies or as a practical solution, as long as it is used with care to avoid risks like vandalism or potential damage to the glass—although the creator of the video says he has never had any issues in over a decade of use.
