Norton, Ohio - Fomo Products says its Handi-Foam E84 Class 1 low-pressure spray polyurethane foam insulation has been approved for use as an air infiltration barrier in buildings of all types of construction. The SPF was tested to NFPA 286 in a simulated end-use configuration, with the product exposed in commercial roof/wall junctures.
Handi-Foam was found to comply with chapter 26 of the 2009 International Building Code, and section R316 of the 2009 edition of the International Residential Code.
Based on this successful testing, E84 Class 1 can be used in types I, II, III, IV and V construction without a thermal or ignition barrier coating, said Fomo. The use of spray foam is limited to a maximum depth of two inches in thickness and six inches in height application.
"Typically, spray foam requires a thermal or ignition barrier to be applied over the foam, but our product is safe to use without either of these in various approved applications," explained Sandy Gump, product compliance manager at Fomo Products. "We are pleased to offer this option to our customers for a quicker job turnaround using less material."
