•  Acoustic Flex is supplied in 10 meter lengths.
• Not a stock item and will require 10 days lead time to manufacture & supply

• Core

  • Constructed from aluminum tape on the inside and metallized polyester tape on the outside which encapsulates a spiral galvanized steel wire and is chemically bonded using self extinguishing fire retardant adhesives.
  • The appearance of the core is silver with perforations at regular intervals.

• Insulation

  • To achieve the published insertion losses the core must be insulated with the following blanket:
  • Thick polyester blanket as specified by the customer to comply with the BCA.
  • Other insulation options available on request.

• Jacket

  • The sleeve is constructed from a silver metallized polyester tape. As an optional extra insulated duct can be supplied with reinforced sleeve. This must be specified at the time of ordering.
  • The sleeve must be fully taped to the spigot as the sleeve acts as the air envelope.
