Finding the gaps and draughts in your building

You can spot draughts by dampening your hand and moving it over the following:

• gaps around windows
• gaps around doors
• gaps between ceilings, cornices and architraves
• gaps near skirting boards
• gaps between walls and floors
• gaps in flooring or floorboards
• gaps where HVAC equipment or piping enters your building
• gaps in vented skylights and cooling outlets
• gaps around vented or recessed downlights

It may be worth hiring a thermal imaging camera. This will allow you to see exactly where the heat is escaping.
