Consequently, do you let heat out or cold in?It isn’t really useful to replace the idea of heat with the idea of cold. Both the warm room air and the cold refrigerator air contain heat. Temperature is “heat density.” Warm air contains more heat per gram than cold air.Additionally, how do you smell proof a door? It’s generally just a toilet paper roll with dryer sheets taped around the top. You blow smoke through it then it comes out smelling like fresh laundry. I prefer to just cram some dryer sheets into an empty water bottle and poke a few holes in the bottom, it works the same. Its called a door snake for the bottom.
