Is aluminum foil paper heat-proof?
Yes, it has certain effect on heat insulation because aluminum foil has high radiant reflectance and can reflect some of the solar radiant. However, it’s not practical due to the complicated construction and being easy to be damaged. You can consider using thermal insulation coating which has advantages of simple construction, obvious effect and long service life and doesn’t need special maintenance in latter period.
It is easier to conduct heat than insulate heat.
No, it isn’t. Firstly, it is aluminum alloy which can conduct heat quickly. Aluminum foil used in micro-oven is to avoid overflow of food, which can resist high temperature but can’t insulate heat and on the contrary, it can conduct heat.
