Re: Re: Stairwell/Corridor wall detail

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…
