Our office does a lot of TI projects in new shell buildings. More often than not the shell building does have CI as required per the IECC (06, 09, 12). Is this not required or is there a work around?
Did you mean they DO NOT have CI as required?More often than not the shell building does have CI as required per the IECC (06, 09, 12).
Yes it is to reduce thermal bridging, in the past when insulation levels were lower adding additional cavity insulation could balance the effect of thermal bridging, current insulation requirements are such that that does not work any more where in some cases a R= 10000000000000 near perfect cavity insulation paired with thermal bridging would not meet the required overall U factor for the assembly.unegamacated said:Isn't the whole point of CI to minimize thermal bridging? So why would additional insulation on the roof, framed walls etc cancel out that requirement?
