We need to put a 110mm toilet waste through a 70mm solid wood wall.
Normally I think you'd concrete this in (?) but not an option here. Plus it needs to look tidy and allow a little bit of flex. Is there some sort of standard collar or something that can go around the pipe and cover the hole for drafts etc? No idea what to Google for.
