I think you may have to source comment in the UK.
Also the UK has a range of climates only some of which approximate Ireland's range.
In general the UK is colder in Scotland and warmer and drier in the Home Counties and London.
Ireland can cause unusual problems with timber and how a timber performs depends to a large degree on how its incorporated into the construction.
In many cases it comes down to detail placement, site orientation, exposure, interstitial spaces adjoining, etc.
