Irvine, California -- Johns Manville and International Fireproof Technology Inc. (IFTI) have added a fire-protection coating, DC 315, for use over a range of spray foams.
IFTI executive vice president Gary Wolfe said in a company statement: "Both companies realise the importance of offering superior, low-cost fire protection over Johns Manville foam products."
DC 315 is a one-coat, water-based latex paint that offers superior fire protection over foam. IFTI says it has completed over 35 successful full-scale Intertek WH certified tests, making the material the most tested and reputable solution in the market.
International Code council-ES reports recognise the DC 315 coating as an acceptable alternative to thermal barriers over either JM Corbond MCSTM CC 2 lb. and JM ccSPF CC 2lb, the company adds.
According to the companies, this gives contractors and foam applicators "increased flexibility and an economical option" to using gypsum board.
Depending on whether the application is a thermal or ignition barrier, using DC 315TM will be a cost-effective, code-compliant, one-product solution, claims the manufacturer.
The materials were tested to the relevant US specifications for use in lieu of a thermal barrier over foam.
