Why would you want to heat the air outside your home. It doesn't make sense but that is effectively what happens in a draughty house.
A quarter of the heat in an uninsulated home is lost through windows and draughts and when we feel colder we turn the thermostat up more than necessary to compensate.
But draught proofing your home is one of the cheapest and most cost effective ways to save energy and all the materials can be found at most DIY shops.
You will save, on average, £55 per year with draught free homes and you'll be able to turn your thermostat down, saving another £65 (for each degree) per year.
Below are listed the areas to look for draughts.
Draught strip around the edge of your front and back doors. It costs very little and is easy to do.
On cold days you will feel cold air coming in through the letterbox and even the keyhole. Cover the inside of your letterbox with a brush seal or even an old bit of carpet and add a keyhole cover ("escutcheon").
If it still feels cold in front of your door a long curtain across the door will shield you.
If your windows are single glazed, you should consider replacing with double or even triple glazing but this can be expensive and in some areas it would not be allowed. In these cases secondary glazing may be a good option instead but an even cheaper and easier option is film (like cling-film) that you put over the window. It doesn’t look odd and it costs very little.
A thick curtain makes a big difference to heat loss and draughts through windows so line them if you can. Help retain the heat by drawing the curtains when at dusk.
Block draughts around loft hatches with strip insulation as you would a door. Don't forget to insulate the hatch by sticking some solid insulation on the back of it.
Chimneys are designed to suck air up the chimney so when the fire isn't on you lose a lot of heat this way. Block it up with a balloon when the fire isn't alight. You can get special chimney balloons but even an old cushion will do the job. Just remember to take whatever it is out of the chimney before you start your next fire.
Floorboards and skirting boards
If you have wooden floors, fill gaps between boards with StopGap or a tube of sealant and put a rug on top. Make sure it is a sealant that allows for movement because wood naturally expands and contracts.
The best solution may be under floor insulation though it is a big DIY commitment.
When a pipe enters the house there is often a small gap around the outside letting in cold air. Fill these up with a sealant, rock wool insulation or expanding foam depending on how large the hole is.
Make sure the flaps on an extractor fan close properly when not in use to prevent cold air entering the house. Old unused fans can be removed and blocked up.
