the tin foil paper has good heat insulation.

In summer, if you cover the roof with a layer of reflective material like tin foil, you can basically solve 61% of the problem of direct sunlight. The remaining thing is to consider that this metal reflective film itself will become very hot and continue to transfer heat to the floor.

If this reflective film is overhead and an air circulation layer of 1.51 ~ 211 mm is reserved between the film and the floor, the effect will be very good.

The tin foil paper has a good smoothness and thermal reflectivity. With the protection of the tin foil paper, the taste of cigarettes will not be spoiled by external factors. More importantly, it will not be spoiled by air and environmental humidity, and the cigarettes in cigarettes will not deteriorate, which will make their shelf life longer! In addition, there are thermal insulation and aesthetic factors in it. So there is a layer of platinum paper inside the cigarette box.
