ComfortSeal 500 — Evaluation Report ER-974

The IAPMO UES report behind our open cell code listing: thermal resistance, surface burning characteristics, thermal and ignition barrier compliance, and installation conditions. An inspector uses it to verify the code listing, the R-value at the installed thickness (Table 1) and the ignition or thermal barrier each space needs (Tables 4 and 5).

ER-974 also lists ComfortSeal 800, which is not offered under the ComfortSeal brand at this time.
