Good day Nash Interesting. Is this fire retardant?
Many yrs ago there was a work van sprayed with insulation & it caught on fire, boy black smoke from that little van.
What is the R value. I know it is best fitting insulate . Thanks

Hey Don. I’m not sure if it’s fire retardant or not and I think around a R20 value. It was a fun little project.
