Hi guys,
I have a cavity around my new bathroom window that wanders between 40mm and 50mm. The cavity is filled with polystyrene beads. Rather than faff modifying a proprietary cavity closer, is it acceptable to use expanding foam?
i.e. is the foam non-porous and therefore won't form a damp bridge, and to me it feels strong enough to take the 'adhesive' when I dry-line the reveals?
Cheers
Gary
