Fiberglass cloth aluminum foil tape is a thin tape that combines glass cloth with a laminate of aluminum foil. Fiberglass cloth aluminum foil tape provides high strength and reflectivity with excellent flexibility.Aluminum foil / Fiberglass cloth backing (7um foil / FR glue / 110gsm glass cloth 12×12), coated with a high performance synthetic rubber-resin adhesive, protected by an easy-release silicone release paper.

The fiberglass cloth provides strength and durability to the tape, making it resistant to tearing and punctures. It also offers heat resistance, which makes it suitable for high-temperature environments. The aluminum foil layer on one side of the tape provides excellent thermal conductivity and acts as a barrier against moisture, air, and other contaminants.

This type of tape is often used for sealing joints and seams in HVAC ductwork, as it helps to prevent air leakage and improve energy efficiency. It can also be used for insulation purposes, such as wrapping pipes or ducts to reduce heat loss or gain. Additionally, fiberglass cloth aluminum foil tape is sometimes used in automotive applications, such as repairing or reinforcing insulation in engine compartments.

Aluminum Foil Tape Applications:

Heat reflective wrap over insulation cables, instruments or other high temperature sensitive materials.
Ideal for industrial applications that will be exposed to movement and vibration.
Bundling wire harnesses.
High temperature/performance applications in the aerospace, automotive and industrial industries.

Aluminum Foil Tape Features:

  • Aluminum-fiberglass Cloth backing provides excellent reflection of both heat and light.

  • Excellent reflection of heat and light is achieved.

  • Low moisture content of these products makes these tapes as a good sealant.

  • It is a excellent vapor Barrier due to low moisture vapor transmission rate.

  • Best Result Obtained when its applied to clean and dry surfaces.
