Cooker Hood Ducting

[elziko]

I am going to fit a ducted cooker hood in our kitchen. Something like this seems ideal:

find. Eventually I got some flexible ducting from Starkey Systems in Worcester

curiously enough). Better than cheap aluminium but still only 125mm not 150mm. And still concertina-style.

I can't see why this stuff wouldn't work OK!
