Insulation
- For a long time humans have used insulation
- Probably the beginning with man wrapping themselves in wool and cloth to keep warm
- Another use of insulation was in the medieval times when straw and mud were packed between walls to try to keep the cold out
- Insulation has been around for along time and yet new things are being invented this year to have better insulation
