Description

Foil Duct Tape in a 50mm wide roll, 45 metres long — ideal for duct sealing, jointing and masking across ventilation installations.

A roll of foil tape belongs in every duct installer’s kit. Use it to seal slip joints between spiral duct and fittings, secure and seal flexible ducting onto spigots, seal cap ends and blanked branches, and tidy up small penetrations and laps. The foil facing bonds well to clean metal duct surfaces and gives a neat, low-profile seal that helps minimise air leakage from the system. A wider 100mm roll is also available for larger joints.

Key features

  • 50mm wide × 45m long roll
  • Seals joints between spiral duct, fittings and flexible ducting
  • Also suited to jointing and masking duties
  • Bonds to clean metal duct surfaces for a low-profile, lasting seal

Frequently Asked Questions

Do I need both sealant and tape on duct joints?

For DW/144 Class C airtightness, use both: apply duct sealant to the male spigot before assembly, then seal the external joint with aluminium foil tape. For less critical applications, one method may suffice, but both together provide the best seal.

Is aluminium foil tape fire rated?

Yes — aluminium foil tape is inherently fire-resistant as it is made from metal. It will not burn or contribute to fire spread, making it suitable for use in fire-rated compartments and plenums.
