Re: Re: 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
