Stairwell/Corridor wall detail

It would most likely be 215 block on flat for the wall, but the stairwell section could be an insitu concrete wall around the same thickness
As for thermal efficient option, a lightweight concrete. such as Aerated concrete blocks, it had a lower conductivity than heavy weight concrete blocks.
Bare in mind that this wall wont lose heat like an external wall would. The temp difference between the corridor and the appartment isn’t anything like the appartment and outside

I’m approaching this from the point of view of an energy rating. Your right about it not being the same as a typical external wall heat loss. Deap allows an increased resistance value of 0.4 in the case of an access corridor. However, without going to the trouble of insulating, it looks like a solid block wall – even if aerated block – will have a big impact on the rating. Will either have to incorporate insulation or design for access corridors to be heated – in which case, walls adjoining access corridors/stairwells can be ignored for the purposes of the calculation. Perhaps the latter is the easiest way out…

The most likely senario is a 215 7N concrete block on flat and as its an appartment block I would assume that its standerd blockwork as its the cheapest solution and most builders will not use lightweight blockwork as its is very difficult to plaster. On another note, are you a registered assessor? I have been trying to book myself into the course in Dublin or GMIT since last December and have had absolutely no luck, a different person answers the phone every time but its always the same answer.

No, but I would be interested in doing the course. Have found the same. There doesnt seem to be any new dates announced as regards training.

The course is being filled from a ‘first come first served’ basis…. depending on when you sent your initial email requesting a place on the course…. you did send an email didnt you??…
