Insulation can be of different kinds namely thermal, sound, electrical etc. Thermal insulation is intended to stop heat exchange between surfaces. There are different ways of heat exchange namely conduction, convection, radiation etc. Numerous materials are used as thermal insulators and it depends on surface on both side.

Job of thermal insulator is to reduce heat transfer. You would have seen steel bottle which is a perfect example of thermal insulation. In thermal insulation, there are five common materials:

  1. Fiberglass
  2. Mineral Wool
  3. Cellulose
  4. Polyurethane foam
  5. Polystyrene
