Hmmm,
Ignore OP. Look at where 's coming from.

its joined on to the house, it used to be a wash room and i live in
the UK
i have an idea which is
( please tell me if you think this is going to be ok )
1, take all boards down and leave batons up in place
2, aquaseal the concrete ceiling ( i used aquaseal on the single brick
walls to seal out any moisture before installing the foam boards) so
its nice and water proof and black lol
3, add the loft insulation ( rockwool glass)
4, add the phonelic foam boards 30mm foil backed
5, grab a coffee

what do we think?
