  • insulation is not of much use if you have draughts
    • draughts will blow away warm air from heating before it can heat up the fabric of your place and your stuff
    • this is not just costly, it reduces the lifespan of the boiler
  • when one draught is sealed, another typically becomes apparent
    • it may take multiple winters to find and plug them all
  • long thin gaps are often hard to spot but have a significant impact

Thermal imaging

  • try HIKMICRO Mini2 Thermal Imaging Camera for Android
  • cannot detect draughts directly, but does show where surfaces are colder due to cold air blasting into or across them
  • exit holes may not show up at all
    • check the outside of the property for hot vents that may be fed via exit holes

Loft hatch

  • in windy weather air blowing across the loft hatch creates low pressure
    • if the hatch has a poor seal, this low pressure extends into the living space where it can suck in cold air through holes (e.g. the floor) that aren't normally draughty
