Insulation placed in the exterior air cavity between brick veneer and a backup wall is now common practice; however, accounting for the reduction in thermal performance as a result of thermal bridging at brick...

A study by Pennsylvania Housing Research Center (PHRC) showed significant reductions in centre-of-cavity R-value for steel-framed wall assemblies, reducing it by as much as 56 per cent when a framing factor (i.e. thermal bridging)...
