⚡ At a Glance
- • Sealing Performance: Inflatable balloon creates an airtight barrier that reduces draughts and wind noise
- • Best for: Homeowners with an unused or open square chimney seeking quick draught reduction
- • Not ideal for: Chimneys that are larger than 300mm x 300mm or irregularly shaped flues
Inflatable balloon fits square chimneys up to 300mm x 300mm and includes a mouth inflation tube. Designed to block draughts, reduce wind noise and stop debris or wildlife entering the flue.
Cut heat loss - with an inflatable balloon seal
The balloon sits inside the flue and is inflated using the supplied mouth inflation tube until it expands to fill the chimney cross-section. The expanded form presses gently against the flue walls to form a close, air-blocking seal.
Less warm air escapes up the chimney, so central heating runs more efficiently and rooms retain heat for longer.
Reduce noise and draughts - with an airtight internal seal
The sealed balloon interrupts airflow down the flue, damping wind-driven noise and reducing pressure differences that cause draughts. The effect is described as like fitting double glazing in the chimney.
Quieter rooms and fewer cold spots, particularly useful on windy nights or for properties exposed to external noise.
Keep out debris and wildlife - with a fully inflated barrier
When inflated, the balloon blocks the open flue space, preventing loose soot, nesting material and small animals from falling or entering the home. The supplied inflation tube allows controlled expansion to suit the flue.
Reduces the need for frequent clearing and lowers the risk of unwanted visitors entering through an open chimney.
