Re: Polyurethane foam insulation
Great, please let us know what they say.
As mentioned it was my sense that the fire rating test was for attics and non-occupied spaces. Where the code assume people, and hence many ignition sources, don't go regularly (not to say there aren't any). So I'd guess the manufacturer says this is a non-approved install, but who knows.
edit: and if you want to help the field of fire science (and my job
) also post the result of your ignition test
This is the foam company reply, common sense.
"The foam is classified as combustible and should not be exposed to high temperatures (> 250F.) or ignition source. This foam product needs open air flow to dry properly"
