Push it up the flue, inflate it, and it seals the gap in under a minute.
Some chimneys narrow to a gap a firm pad cannot reach. The Chimney Balloon inflates to fill that space, holds by inflation alone and comes straight back out, so it goes up each autumn and down each spring.
A small 15 x 9 inch inflatable chimney balloon draught excluder. It holds by inflation alone, needs no tools and can be reused every winter.
About this chimney draught excluders
Not every chimney is a neat straight box. In many houses the opening narrows to a throat, then widens behind it. A firm pad cannot push through the narrow bit, but an inflatable can. The Chimney Balloon goes up deflated, then it is blown up to fill the wider space behind the constriction.
The small size is 15 x 9 inches, and the right size is what makes it seal, so measure your opening first. It is inflated through a mouth tube or a pump and holds by inflation alone, with nothing screwed or glued in place. It seals the gap in under a minute and comes straight back out.
A balloon is a good option if you cannot fit a pad, or if you want a reusable seasonal seal that is easy to store. Like any chimney blocker, it must come out before you light a fire, so pop the reminder card where you will see it. It is a draught excluder for an unused chimney only.

The complete guide
A pad fills an opening it can reach. If the opening narrows and then widens, the pad stops at the narrow part.
Inflated behind the constriction, it fills the wider space and seals the flue.
After inflating, tug gently on the tube to feel whether it is held. Check it from time to time over the winter.
