Why having no draughts is important
Keeping the heat in is a key element for good home performance and the overall comfort and health of a dwelling. When you turn on your heaters, you want to warm up your home, not lose that heat outside.
Gaps, cracks and holes in the building envelope, especially around windows and doors, account for up to 10% of heat loss from an average home. It doesn’t matter how much insulation is in your attic if you have a howling gale coming in around the front door.
