Draught Proofing Your Home

PPG_Blog_June_image 3_draught proof your houseEven if your home is well-insulated, hot or cold air can still leak in and out through gaps and cracks. Older, period homes are particularly vulnerable to draughts. According to the government’s Living Greener website, cutting down on draughts can save households up to 25% of the heating and cooling bills. Draught proofing your home is one of the easiest and cheapest ways of lowering energy costs.

The most common air leaks can be around doors, windows, skirting boards, cornices and floorboards. Also watch out for gaps around internal doors to heated areas and to ventilated rooms such as bathrooms or toilets. Fans and chimneys can also be a frequent source of draughts.

Seal gaps and cracks

Look for gaps and cracks and block or fill them. They are often found around doors and windows. Check floorboards, architraves, skirting boards, sky-lights and cornices – anywhere there are joins.

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.

Check fans, vents and other outlets

Install automatic closing mechanisms over exhaust fans and vents. You may be able to add covers to existing fans.

If you are at all unsure, talk to an electrician or supplier for advice. Air does need to flow in and out of your house so it stays fresh, dry and healthy so you don’t want to block or seal any intentional ventilation:

  • under-floor grilles or airbricks – these help keep wooden beams and floors dry
  • wall vents – these let small amounts of fresh air into rooms
  • trickle vents – modern windows often have small vents above them to let fresh air trickle in
