Draught exclusion
From YM2149.org
- 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
