In our kitchen we have a perfectly ordinary cooker hood vented outside. Trouble is, there is quite a draught from it. It exits into the gap between our house and our neighbours' - which can be pretty windy. Fine when cooking, but makes the whole kitchen a bit chilly in the winter.

Is there a simple (but effective) way of reducing airflow when we are not using it?

Obviously we could shove a rolled up newspaper in the hole - but that is hardly convenient!


Does it have "back draft shutters" fitted?
They are thin light plastic spring loaded flaps (usually a pair,
each semi circular) usually mounted immediately before the
ducting connects to the fan output spigot.

They are pushed open by airflow from the fan being on, then when
fan is off they shut due to their springs. You usually hear them
as they "slap" shut after the fan is switched off...


They can't be fitted to cooker hoods.

Utter ******** - they are a standard fit.

The grease soon jams them.
Usually the metal filters stops much backdraught.

The filters are there to filter the grease before it gets through
the fan...

Are the filters fitted?
