The Fire Rated Material Specialist
FRM and the UL-U370 firewall are proprietary to GreenFiber. The UL-U370 firewall currently has patents pending. Only the Fire Rated Material Specialist contractor has received training from GreenFiber in the proper application and density testing required to spray this assembly.
 
GreenFiber will sell, supply and distribute its FRM product only to FRM Specialists. The FRM product is easily identifiable by its terracotta color, and the UL label on the bag. The FRM Specialist should also be able to provide you with the appropriate documentation which verifies the correct installation of FRM and meets Underwriters Laboratories, Inc. requirements.
