Vapor-Fas™ 62-05 is a flexible vapour barrier jacketing material designed for use over insulation on commercial ductwork, piping and equipment. It is comprised of a 5-ply aluminium and polymer laminated film with an aggressive pressure sensitive adhesive and release liner. The special multi-ply laminate film contains an outer protective coat that improves resistance to UV and environmental contaminants. It has extremely low permeability and has excellent resistance to puncture and tearing. Vapor-Fas™ 62-05 provides protection to the insulation from weather, moisture ingress and physical abuse. Service temperature (at jacketing surface): -40 °F to 300 °F (-40 °C to 150 °C).
