time and temperature dependence of the transformer oil and its insulation paper used
Aluminum foil is a thin, pliable sheet of aluminum used for cooking, packaging, cosmetics and insulation.
Asbestos sheet, ceramic or marble may be used as insulators.
Usually fibreglass batts held in by a plastic fabric sheet.
Since sheet rock is already manufactured, there is nothing to "put in" it. To soundproof on interior walls the best solution is to add insulation between the stud walls--usually rolled insulation works best, is relatively cheap and will not shrink the room size.
Not a good idea. It really needs to breathe. You can trap moisture and create a mold situation.
Asbestos provides better insulation, because it is thicker and denser than iron.
The r-value of a sheet of newspaper is typically around 0.04 per inch thickness. This means that newspaper provides minimal insulation value compared to other building materials.

The hypodermis lies under the dermis and is made of fats cells which act as an insulation.
Some insulation wrapping such as a towel, some bubble-wrap or expanded polystyrene sheet.
The R-value of steel sheet metal is relatively low, usually ranging from 0.02 to 0.04 per inch. This means that steel sheet metal is not a very effective insulator and does not provide much resistance to heat transfer. Additional insulation such as foam or other materials is typically needed to improve the thermal efficiency of structures made from steel sheet metal.
