Stopping the heat losses at home

1 The Browns live at no. 4 and the Smiths live at no. 3. Their houses are identical except that the Browns insulated their house carefully. Today, the heating bills arrived. £70 for the Browns, but £150 for the Smiths!

Look at the diagram. Complete the table to show where the Smith family could save money – and be more comfortable too. One example has been done for you.
