Johns Manville and International Fireproof Technology Inc. (IFTI) announced the addition of DC 315 to ICC ES report numbers ESR 3287 and ESR 3159 for use over JM Corbond MCSTM CC 2 lb. and JM ccSPFTM CC 2lb foams.
The ICC ES reports recognize DC 315TM as an acceptable alternative to thermal barriers over either JM Corbond MCSTM CC 2 lb. and JM ccSPF CC 2lb. Contractors and foam applicators now have increased flexibility and an economical option instead of using ½ inch gypsum board. Depending on thermal or ignition barrier application, using DC 315TM will be a cost-effective, code-compliant, one product solution, claims the manufacturer.
