Should SIPs really be classified as “continuous insulation” in modeling software or in general?
Today I was looking over a REScheck summary on a set of architectural plans and I noticed that SIPs are specified as “continuous insulation”; however, as I look at the plans I can clearly see that there is framing around the windows, double top plates, bottom plates, etc. Additionally, we are located in area with 150lb snow loads, so the SIPs have internal dimensional framing to increase their load capacity. How can these panels be considered continuous when they are filled with thermal bridges? I agree that SIPs have their benefits with certain application, but I feel as though their performance characteristics tend to be overstated.
