What is a draught excluder?
A draught excluder is a simple barrier that blocks the gap under or around a door. Cold air sneaks in through those gaps and warm air escapes, so your heating works harder than it needs to. A fabric door snake, a brush strip or a stick-on foam seal all do the same job in different ways — and most cost less than £25.
