Sucking the comfort out of your home via internal walls

This is a common problem in homes built up to the 1980’s with connectivity to a cold subfloor and roof. The floor stops and starts to internal walls, and back at this time we didn’t use concrete slabs.  This problem could be affecting the comfort and health of your home. Air infiltration through internal walls in your home can negatively impact significantly, building performance, especially considering the huge surface area of internal walls inside homes. Mark Pohlner from Efficiency Matrix covers some of the finer details of how this problem is contributing to building performance degradation and an explanation of how this problem can be reduced.
