The ESR report (#2715) expands the possible exterior wall applications to include Type I-IV for commercial projects in addition to the product’s existing approval for Type V exterior wall use. The approval now means that Icynene LD-R-50 maintains the same commercial approvals to the manufacturer’s chief open-cell product Icynene Classic (LD-C-50). Together with the ICC-ES, Icynene conducted a series of analyses, including NFPA 285, 259, 286 and ASTM E119, for suitability in commercial projects opening up the range of possibilities for commercial architects and builders looking to use the castor-oil-based open-cell spray foam.
Like Icynene Classic, Icynene LD-R-50 can be applied without an ignition barrier on the floor of attics as well as crawlspace applications.
In addition to the ICC-ES report, the green product has been approved by IAPMO ES as well as the NAHB Research Center as a Green Approved product. Icynene LD-R-50 features castor oil which is considered a renewable product since production of castor beans has a low energy dependence and does not require pesticides, fungicides or man-made irrigation.
