What is the difference between regular aluminium foil and heat-resistant aluminium foil tape?

The main difference between regular aluminium foil tape and heat-resistant aluminium foil tape is that the latter can withstand higher temperatures. This is due to the reinforced fibreglass backing, which makes it more heat-resistant. The regular aluminium foil tape is thinner and less heat-resistant, making it more suitable for general repair jobs around the house. However, both types of tape are helpful for different purposes.
