Aluminum Foil Tape Description


Aluminum foil insulation tape is a type of adhesive tape that is specifically designed for use in insulation applications. This aluminum foil tape typically consists of a layer of aluminum foil on one side and an adhesive on the other, and is used to join and seal pieces of insulation together, as well as to cover and protect insulation from damage. The reflective surface of the aluminum foil also helps to improve the efficiency of the insulation by reflecting heat back into the interior space.

Aluminum foil insulation tape is widely available in different widths and lengths, and it is often used in construction, HVAC, electrical, and industrial applications where insulation, sealing, and moisture protection are required.

Tape Applications:

Thermal insulation: The aluminum foil backing acts as a radiant heat barrier, reflecting heat away from the insulated surface. This makes it useful for insulating pipes, ductwork, and other surfaces where heat reflection is desired.

Vapor barrier: The aluminum foil provides an effective barrier against moisture and vapor, making the tape suitable for sealing joints, seams, and gaps in insulation materials, preventing moisture intrusion and condensation.

HVAC and ductwork sealing: The tape is widely used in HVAC (Heating, Ventilation, and Air Conditioning) systems to seal seams and joints in ductwork, preventing air leaks and improving energy efficiency.

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 AFR5090 an excellent vapor barrier.
  • Service Temperature range from -20℃ to +80℃.
