Hi,
The house we bought last year was having a problem with condensation along the bottom of the internal walls during autumn/ winter so I think ewi is needed because filling the cavity didn't cure it.
The problem I have is I need to continue the insulation down to ground level because internal floor level is around 450mm above external ground level, and the 450mm which is exposed outside is solid, the cavity ended at interval floor level.
I've been reading about using XPS along the bottom and EPS above, but I live in Northern Ireland and no one on the island of Ireland seems to have heard of XPS, and delivery cost from the mainland is mental.
So is there an alternative to XPS? And would I need to take the insulation down below external ground level? I've included a wee diagram to show how the external wall is constructed. Many thanks for any advice given, cheers
