Spray applied foam

[Inspector 102]

Section 2603.9 indicates that spray foam does not need a thermal barrier if NFPA 286, UL 1040 or UL 1715 can be met. I have a assembly building at the local fairgriunds that they have spray foamed and to date no thermal barrier applied. Does anyone know a brand name of a spray foam that will meet these requirements for eliminating the thermal barrier. Thanks

There are some that don't need it depending on where it's sprayed. Really need to find out what they used and track down the info.

Get the installed spray foam manufacturers evaluation report; ICC ESR # or acceptance report that spells out the application restrictions.
