Stormguard Chimney Inflatable Draught Excluder, Transparent, 700mm (562VV) review
The same job as any chimney balloon — sealing a genuinely unused flue — but with the safety limit stated on the product itself.
By Tom Calder · Updated 24 July 2026 · Price checked against our tracker
Functionally similar to the Chimney Balloon brand's version, but this one states its own safety limit on the pack: 'ensure product is deflated and removed before lighting a fire.' That single line does a lot of the safety work for you, which is why it's the one to reach for first in this category.
Confirmed at £16.99 inc. VAT on Screwfix as of Jul 2026, including a 1-year guarantee.

- On-pack warning to deflate and remove before lighting a fire
- Simple push-fit and inflate, no fixings needed
- Comes with a 1-year manufacturer guarantee
- Still requires the underlying rule to be followed: only fit in a genuinely unused or confirmed-redundant flue
- Transparent plastic construction, with no stated insulation performance beyond blocking the draught
- Fixed maximum size (up to 700 x 400 x 250mm inflated) — measure your flue opening before ordering
