    • Save up to 25 per cent on your heating and cooling bills
    • Easy and affordable to implement—even for renters
    • Noticeable improvements to household comfort levels

Seal gaps and cracks

Look for gaps and cracks and block or fill them. They’re often found around doors and windows. Check floorboards, architraves, skirting boards, sky-lights and cornices—anywhere there are joins.For a quick, easy option for filling gaps around door architraves and along skirting boards, pick up some gap filler (caulk) and a caulking gun from your local hardware store. For bigger gaps you can try polyurethane expanding foam.

Install draught stoppers

Put draught stoppers at the base of doors to help keep warm air in during winter and cool air from escaping in summer. There are a number of different products on the market including flexible strips that attach permanently to the bottom of your door to the humble fabric ‘sausage’.

Check fans, vents and other outlets

Install automatic closing mechanisms over exhaust fans and vents. Talk to an electrician or supplier for advice. You may be able to add covers to existing fans.To avoid heat loss from evaporative cooling ducts during winter you can cover them with a specifically designed cover; or for a cheaper option simply clean the vent and cover it with clear plastic contact that you can remove when the weather warms up again.
