Hi all,
I have a flat roof which has some insulation built in but I as I am redecorating the room below I would like to take the opportunity to add some more internally if possible. I don't want to disturb the plasterboard and I was wondering if I could attach 25mm Celotex directly to the existing ceiling and then a layer of plasterboard to create a new lower ceiling ? I'm a bit worried about securing it all but if I can identify where the joists run then I can attach the board throught those.
Any thoughts would be appreciated !
Thanks,
Andy.
