HVAC foil tape for wide-temperature sealing

This Nashua 330X roll uses an aluminum backing with an acrylic adhesive to seal ductwork and insulation. It performs continuously from minus 35 degrees Fahrenheit up to 260 degrees Fahrenheit. The tape meets UL 723 and FAR 25.853(a) standards for flame and smoke performance.

Check surface and temperature range before ordering

Ensure the substrate is clean, dry and free of oil so the 55 ounces per inch adhesive can bond properly. Verify that the operating environment stays within the listed minimum and maximum temperatures. Confirm that a 48 millimetre width and 46 metre length suit the joint dimensions you plan to cover.

Replaces cloth or rubber tapes that fail

The 3.50 mil thickness and 14 pounds per inch tensile strength resist tearing during installation and service. Upgrade when existing tape delaminates, cracks or loses adhesion under thermal cycling. The aluminum backing also provides a vapour barrier that many general-purpose tapes lack.
