Do you need draught proofing?
Here's a simple test - hold the palm of your hand up against the windows in your home. If you feel cold air coming through, warm air is escaping. In fact, in a typical home 20 per cent of all heat loss is through ventilation and draughts.
A draught is a sign of poor insulation. As cold air enters the house, warm air exits. This ends up costing the homeowner unnecessary heating bills, and heats the outside environment.
Draught proofing comes in a variety of forms, mainly brushes, rubber seals and plastic/metal frames. Doors are the most common source of draughts, along with letter-boxes and keyholes.
Therefore front/back doors and porches are the most important areas to draught proof. This will keep warm air in during the winter, and reduce heating bills.
It is important not to apply draught proofing to bathroom or kitchen doors or windows. These rooms produce high amounts of condensation, which if not ventilated correctly will cause mould and similar problems.
With a well-insulated home, it is important to ventilate in order
to keep the building from becoming stuffy.
