Steel framing also has a tiny fraction of the r-value of wood. It might seem like the framing element is irrelevant but it adds up quickly. A layer of R-19 batt insulation is 63% less restive to heat transfer (effectively R-7.1) when installed in an assembly of 2x6 metal studs on 16" centers, compared with R16 in the same assembly in wood. |
