I have been involved with one instance of Albi application, in Cally. It was a duplex, with plenty of egress. Application was in concealed spaces between floors. But, it was expensive. Less so, though, than the cost of dry-walling up all the joists, individually. Could not convince the jursidiction that the entire floor (joists and floor/ceiling) comprised a system, and the individual joists did not need individual protection. That, was MY failing. Rather than drag the process out, on a loan that was already expensive, the builder decided to apply Albi.
My question though, is what testing do we have that shows these film applications are still as effective, 10 years down the road, especially exterior applications or attic applications with extreme heat variations. Sprinklers should be tested 10 years down the road, why not fire-rated film-over-wood applications? Maybe NIST has some on-going experiments that are in year 5 of a 10 year plan?

Intumescent paints have been around for a long time. The good companies have UL certification(both U.S. and Canada), require factory trained applicators, and require Special Inspections under 2006 IBC and AWCI 12-B. The brands I am most familiar with are ALBI and PPG, but, there are hundreds.
