- 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
