These versatile Class A approvals allow for installation of a single layer of these products or in combination with additional layers of ENRGY 3 insulation.

Demand has been growing steadily for Johns Manville TPO, ever since we launched it in 2008. Due to this increased demand, JM realized back in 2015 that we needed to expand our production capabilities. At that point the decision was made to expand our TPO plant located in Scottsboro, AL and add a new production line.
