Foster 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. Foster Vapor-Fas™ 62-05 provides protection to the insulation from weather, moisture ingress and physical abuse.

Service temperature (at jacketing surface): -40 °F to 250 °F (-40 °C to 121 °C)
