Is it ok to insulate kitchen ceiling with foil insulation?

[Simon1979]

Hi,

I am taking down my kitchen ceiling and having a new plasterboard me put up. I don't have any heating I'm my kitchen so while the ceiling is down I thought I would insult it using that foil backed roll insulation (like silver bubble wrap).
If I leave 50mm gap from the ceiling joist is this ok to do and not cause me any moisture issues?

I am also putting in a chimney extractor Hood and also thought I could hide the ducting in the ceiling space rather than building a bulkhead. This with the insulation can anyone think if this may cause me any moisture problems please?

Thank you very much for your help, this forum is brilliant!

Kind regards

Simon

That foil insulation wont do a thing if you have no heating, and not much if you did. But it will potentially be a condensation barrier which drips back down to the plasterboard

I can't think a a reason to insulate a kitchen ceiling unless its a roof too. If you insist, then use quilt instead and foil-backed plasterboard
