3M™ Aluminum Foil Tape 3369 is a malleable, dead soft aluminum foil coated with a cold weather solvent acrylic pressure sensitive adhesive. At only 1.1 mil thick, the thinnest in the line, it applies easily to both fibrous and sheet metal ducts and conforms to irregular surfaces. This tape resists flame, moisture, weather, UV degradation and most chemicals for long-term durability.
  • Thinnest backing in the aluminum tape line at 1.1 mil
  • Ideal for use as a vapor seal for reinforced fiberglass or mineral wool thermal insulation
  • Combines quick adhesion with good low and high temperature performance
  • Acts as a vapor barrier to insure the integrity of insulation
  • Heat and light reflective tape protects while enhancing lighting efficiency
