Cotton wool has a very low density and has thousands of pockets to trap air in. Because of this, cotton wool is a good insulator, but there are others that are better. As a rule of thumb, the lower the density, the better the insulator. There are virtually no exceptions to this.
wool insulates heated water best because woll is the best insulator.
Yes sawdust is an insulator such as Wood, Plastic, Styrofoam, Rubber, Paper, Glass, Cotton, Sand, Aerogel, and Wool. Cotton and Wool is likely to be found in a sock. These insulators can stop heat or electricity from flowing through them.
