Flat and tapered ISO 95+ GL insulation provides outstanding thermal <br /> performance on commercial roofing applications, while providing positive rooftop drainage to help eliminate ponding water <br /> when tapered ISO 95+ GL insulation is used. <br /> All Firestone polyisocyanurate foam insulations use EPA accepted blowing agents. Firestone ISO 95+ GL incorporates a <br /> HCFC-free blowing agent that does not contribute to the depletion of the ozone layer(ODP-free). <br /> Method of Application: <br /> 1.
