Home » Johns Manville Readies Polyiso Facilities for Production with Pentane
Johns Manville converted its Jacksonville, Fla., manufacturing facility to produce polyiso foam roof insulations with pentane, a non-ozone-depleting blowing agent.
Johns Manville, Denver, converted its Jacksonville, Fla., manufacturing facility to produce polyiso foam roof insulations with a non-ozone-depleting blowing agent, pentane. As a result of a multimillion-dollar effort, Johns Manville’s Hazelton, Pa., and Brennan, Ind., production locations will soon follow.
As part of its conversion process, Johns Manville Roofing Systems Group adopted an advanced scientifically supported methodology called Long Term Thermal Resistance to accurately predict the long-term R-value of polyisocyanurate insulation. The method is based on accelerated aging by conditioning thin slices of foam insulation and is based on consensus standards in both the United States and Canada.
