The average home uses up around 38 percent of energy consumption just for heating and cooling. Starting with your front door, we'll show you some simple ways to winter proof your home by keeping the cold out and sealing in the warmth.

Tools and materials


1Seal around your front door

Drafts from your windows and doors can account for 25% of the heat loss in your home. You can use a rubber seal on your windows or doors to fill gaps of 3-5mm. Tear the rubber seal in half and remove the adhesive strip. Stick it onto the inside edge of the door stop, starting at the very bottom, and then work your way up to the top and straight across.

2Install a storm proof seal on the bottom of the front door

Door seals work by pushing the flap down when the door shuts, keeping the wind and the rain out. There are many different sorts of storm seals and adhesives. Make sure you choose the right one for your type of door.

3Lay down rugs on timber floors

Hardwood floors and tiles look great but can get very cold. In particular, hardwood floors often have gaps that let in drafts. It's a good idea to lay down thick rugs on these types of floors. They feel great underfoot and stop the winter chills.

4Check your window seals and close the blinds

Make sure your windows are well sealed. Check that the external and internal seals are in good condition and push hard against each other when the window is closed. Closing your blinds and having good quality block-out curtains can reduce heat loss by 10% in your room.

5Use door snakes on hardwood and tiled floors

Door snakes come in all shapes and sizes. Pick one that is the right width for the door. A double snake goes one inside and one outside. Slide the flat centrepiece under the door and it stops drafts on both sides.

6Put ceiling fans in reverse

If you have a ceiling fan there's usually a reverse mode for winter. This will push all the warmer air down, making the room temperature more comfortable.

7Insulate the roof

You can also insulate your roof. Installing insulation batts above your ceiling will help keep your home warm in winter and also cool in summer. However, it's important to consider the type of insulation that will best suit your home.
