Insulation delivers fire resistance

Johns Manville has introduced ENRGY 3®.E, polyisocyanurate insulation inherently fire-resistant without added halogenated flame retardants, to its polyisocyanurate product line.

The insulation features a reactive polymer modifier to improve cell structure and foam properties and reportedly meets Class A fire ratings in low-slope roof assemblies. The insulation has comparable fire, mechanical and thermal-performance characteristics and is said to have the highest R-value per inch of any commonly used roofing insulation.
