  • Double glazing reduces energy
    • loss by conduction
      • particles in a vacuum cant transfer energy by conduction.
        • Loft insulation
  • warm air rises.Energy transferred through air by conduction
  • Air in the loft in trapped both sides of the celing have the same temp.
    • Cavity wall insulation traces energy loss by conduction and convection
      • Air is a good form it is a good insualtor.
        • Air cannot move by convection it is trapped in the foam.
  • Roof tiles energy is transferred to outside by conduction.
