Has anyone investigated or compared EIFS through EC lenses?
Thanks,
Payette’s Kaleidoscope tool shows an EIFS assembly in comparison to other opaque assemblies, for both mineral fiber board and XPS (HFO-based, I believe) insulations. I think some of the GWP values are derived from Tally LCA.
The attached image is a comparison of the EIFS layers only (no backup) using STO’s EPDs, looking at the differences in insulation types and adhesion methods. HFC-based XPS is off the chart/truncated, but I left it there since I believe it is still in use in some US states. Cementitious adhesive is much less GWP than the SPF, but I’ve heard some installers may find it less practical for higher buildings, due to the weight.
