Where my copper pipework in bedroom airing cupboard goes up into the attic there is quite a gap where small section of ceiling was chased out rather than drilling four holes etc. Could I use expandable foam to block this gap or will the material react with copper? Me and the wife thought we may have heard a mouse or something in attic last night so dont want anything dropping down.
I'm guessing if the pipes ever needed to be worked on the foam could be cut away with a stanley knife or something
