I've got myself a nice new hood, all ready to be fitted and boxed in but do not want to pay the crazy prices britannia charge for ducting kits (also I need a 45 degree bend which they dont do)
Can anyone advise somewhere that sells 150mm 45 degree pvc rigid bends and also, whether I can mix pvs piping with galvanised steel?
I ask about mixing two types of ducting because I have, so far, only managed to find 45 degree bends in galvanised steel.
Any help would be greatly appreciated
