Under the IRC, the insulation may be used as air- impermeable insulation under IRC Section R806.4, when REPORT HOLDER: installed in accordance with Section 3.5. The insulation may be used in exterior walls of Types I, II, III, and IV JOHNS MANVILLE construction when used as described in Section 4.5. 71717T"STREET 3.0 DESCRIPTION DENVER,COLORADO 80217 (800)654-3103 3.1 General: www.im.com JM Corbond MCST"' insulation is two-component, spray- applied, rigid, medium-density, polyurethane foam EVALUATION SUBJECT: plastic having a nominal in-place density of 2.1 pcf. The JM CORBOND MCSTM' SPRAY-APPLIED POLYURETHANE insulation is produced in the field by combining a INSULATION polymeric isocyanate(A component)with a polymeric resin (B component). The liquid components are supplied in 1.0 EVALUATION SCOPE 55-gallon (208 L)drums and 250-gallon (946 L)totes. The polymeric isocyanurate (A component) has a shelf life of 1.1 Compliance with the following codes: twelve months when stored in factory-sealed containers at temperatures between 60°F(15.5°C)and 75°F(24°C).
