AP/ArmaFlex are flexible insulation products that reliably protects against water vapor ingress due to its closed-cell structure. No additional water vapor retarder is required, for most applications. AP/ArmaFlex is manufactured using nitrile rubber and polyvinyl chloride (NBR/PVC) formulations for insulation thickness up to and including one-inch wall thickness. --AP/ArmaFlex FS and insulation thickness greater than one-inch wall thickness are manufactured using Ethylene Propylene Diene Monomer (EPDM) formulations.
