Air conditioning duct tape combines flexible foil for irregularly-shaped applications and excellent low temperature performance. Aluminum duct tape conforms to fibrous ductboard and sheet metal ducts and works well in general-purpose heat shielding and light reflecting applications. Air conditioning tape is typically used to seal gaps, joints, and seams in ductwork, helping to prevent leaks and improve energy efficiency.

Air conditioning duct tape is high-quality, high tensile strength aluminum foil coated in epoxy resin with strong, cold-weather solvent acrylic adhesive set on a easy-release silicone paper liner to preserve the adhesive and provide ease of use.

Aluminum Foil Tape Applications:

  • Fibrous ductboard, sheet metal ducts and blankets.
  • Applications requiring flexibility and good temperature performance.
  • General purpose aluminum foil tape for a variety of applications.

Aluminum Foil Tape Features:

  • Multi-purpose foil tape for HVAC industrial applications.
  • Nominal 40um aluminum foil is excellent for use on fibrous and sheet metal ducts.
  • Low moisture vapor transmission rate makes AFR4080 an excellent vapor barrier.
  • Service Temperature range from -20℃ to +80℃.
  • Flexible foil conforms well to curved or irregular surfaces.
  • Hand tearable and easy to install on site without special tools or application methods.
