The company said Commercial ComfortTherm™, like its residential predecessor ComfortTherm(, is poly-encapsulated and meets a variety of thermal and acoustical needs in new commercial constructions and renovation-retrofit projects. Per the manufacturer, the product is UL-classified FHC 25/50 per UL 723, and has flame spread 25 or less, and smoke developed 50 or less when tested in accordance with ASTM E 84. The poly facing and triple-reinforced flanges are significantly tougher and more tear-resistant than kraft-faced insulation, it said. — Johns Manville Denver
