Heat loss from a house

The heat loss from a house can be reduced by:

1. Loft insulation
2. Double glazing
3. Cavity wall insulation
4. Curtains, blinds and shutters
5. Carpets
6. Draught excluders
(The figures in brackets are after adding insulation.)

The heat loss is much greater when it is cold outside and especially if it is windy as well.
