Aluminum Foil Tape Description


Aluminum foil tape HVAC is typically made of a thin aluminum foil backing coated with a strong adhesive on one side. The aluminum foil provides a barrier against moisture, air, and heat, while the adhesive ensures a secure bond when applied.

Aluminum foil tape is designed to withstand high temperatures typically encountered in HVAC systems. It can resist heat from HVAC equipment and ductwork, making it suitable for applications where thermal resistance is required.

Aluminum foil tape is flexible and conformable, allowing it to easily adhere to irregular surfaces and contours. This flexibility makes it versatile for various HVAC sealing and insulation tasks where a tight seal is needed.

The aluminum foil backing of the tape provides durability and resistance to tearing, punctures, and moisture, ensuring long-lasting performance in HVAC applications.

Tape Applications:

Common applications of aluminum foil tapes in HVAC systems include sealing joints, seams, and connections in ductwork, air vents, and other components; insulating ductwork and pipes; repairing damaged insulation; and secure insulation materials such as fiberglass or foam board on ductwork, pipes, or other HVAC components.

Tape Features:

  • Aluminum backing provides excellent reflection of both heat and light.
  • High quality adhesive with super strong adhesion and holding power.
  • Low moisture vapor transmission rate makes AFR3070 an excellent vapor barrier.
  • Service Temperature range from -20℃ to +80℃.
