I have read various comments on doing this and need some help.
I live in a flat which has shared heating, with a pipe running behind some kitchen cupboards and one into a utility cupboard in the lounge, both pipes coming from my neighbours property.
My neighbour has taken up weed and where the pipes go through the concrete wall there is a sizeable gap which seems to be letting smoke and smell through.
Unfortunately these pipes are behind other pipes which means my access is very limited so I would like to fill the gap around the pipes with expanding foam to hopefully block the fumes (and thus stop having to explain to my visiting family that I haven't taken up drug smoking).
Does anyone know if the foam will block the fumes, is it safe to use around the copper pipe and if not is there anything else I could use to fill the gap?
