Dot and Dab and insulation question
Discussion
Hi all, I'm doing a renovation project with a client and he has put silver front and back celotex insulation boards over old walls (internal stone walls) and fixed them to the wall with stud fixings. He then wants to dot and dab plaster board (12.5mm) straight onto the celotex. One section is over 20 feet high by 20 feet wide.
My question is does it stick to the silver foil. He has bought a few bags of standard dot and dab adhesive already and he wants to start this Monday. I'm concerned the silver foil is not porous enough? Thanks for any help.

We have tried, it's a nightmare. The wall behind is stone and old, all very crumbly. Another way would be to use "chem bolts" but it would be a few days work plus the cost of chem bolts, baton and general fiddly work. But it tend to agree with prev. comments that i sounds dodgy. Somebody suggested using expan. foam....but it's a very large area.....
Dot and dab adhesive won't stick foil backed plasterboard (I've learnt).
Was the original wall plastered/flat? A lot of effort using stud fixings to attach the selotex!
I reckon your best bet to rectify now is stud out with batten. Don't forget the top and bottom first. Each batten will probably only need three screws each. If you hit a dodgy spot, try again a few inches away.
