Handi-Foam E84 Class 1 is a low-pressure spray polyurethane foam (SPF) insulation that serves as an air infiltration barrier in all types of buildings. This insulation can be left exposed in commercial roof and wall junctures due to meeting NFPA 286.
The foam can be used in types I, II, III, IV, and V construction without a thermal or ignition barrier coating. It can be applied up to 2 inches thick and 6 inches in height for roof-wall junctures and is also suitable for use with roof penetrations, where it is limited to non-fire-resistant roof assemblies with a maximum of 2 inches of height exposed below the roof deck.
