  5. How heat is lost from a house

  6. 25% of the heat is lost through the roof

  7. 25% of the heat is lost through the roof 15% of the heat is lost through the windows

  8. 25% of the heat is lost through the roof 15% of the heat is lost through the windows Draughts, 15%

  9. 25% of the heat is lost through the roof 15% of the heat is lost through the windows Draughts, 15% Into ground, 15%

  10. 25% of the heat is lost through the roof Walls, 30% 15% of the heat is lost through the windows Draughts, 15% Into ground, 15%

  11. How heat is kept in a house

  12. 10cm of fibre glass insulation reduces heat loss through the roof by 75%

  13. 10cm of fibre glass insulation reduces heat loss through the roof by 75% Fill the cavity in the walls with foam and reduce heat loss by 50%

  14. 10cm of fibre glass insulation reduces heat loss through the roof by 75% Double glazing can reduce heat loss from the windows by 50% Fill the cavity in the walls with foam and reduce heat loss by 50%

  15. 10cm of fibre glass insulation reduces heat loss through the roof by 75% Double glazing can reduce heat loss from the windows by 50% Fill the cavity in the walls with foam and reduce heat loss by 50% Draught excluders are cheap and stop heat loss

  16. 10cm of fibre glass insulation reduces heat loss through the roof by 75% Double glazing can reduce heat loss from the windows by 50% Fill the cavity in the walls with foam and reduce heat loss by 50% Draught excluders are cheap and stop heat loss Solid concrete floors lose only half as much heat as wooden ones.
