  • Withstands 300 °C instantaneous heat for demanding thermal tasks
  • 20-metre roll covers large duct runs without joins
  • Thermally conductive foil boosts heating and cooling efficiency
  • Self-adhesive backing bonds instantly to metal seams and vents
  • Chemically resistant and light reflective for durable HVAC sealing

Aluminium foil tape 55 mm × 20 m

This self-adhesive aluminium foil tape combines a durable foil backing with a silicone adhesive for high-temperature sealing tasks. It is supplied as a single roll measuring 55 mm wide and 20 m long, suited to HVAC ductwork, heat-sink insulation and general industrial repairs.

Installation fit and coverage

The tape adheres directly to clean metal surfaces without additional fasteners, conforming to duct seams and pipe joints to block air leakage. Its 0.06 mm thickness adds minimal bulk, leaving clearance tight spaces while the 66-foot length covers multiple joints in a single roll.

Sustained thermal performance

Rated for continuous exposure up to 100 °C (212 °F), the tape maintains adhesion and reflectivity during long heating cycles. Short-term peaks of 125 °C (257 °F) and instantaneous spikes near 300 °C (572 °F) are tolerated without delamination, making it reliable for repeated thermal cycling.

Questions about this item

What is the maximum long-term temperature this 55mm foil tape can handle continuously?

The tape is rated for long-term use at about 100C (212F), so sustained exposure above that level will degrade the adhesive and foil.

Does the 0.06mm thick aluminum tape stay flexible and cool when wrapped on a hot duct all day?

The thin foil and silicone adhesive remain pliable up to the 125C short-time limit, but prolonged heat above 100C will cause the adhesive to harden and lose grip.

What surface preparation or primer do I need before applying this self-adhesive tape?

Clean the metal or duct surface so it is dry, oil-free and above 10C; the one-side adhesive bonds directly without extra primer or activator.
