Aluminum foil glass cloth tape is a thin tape that combines glass cloth with a laminate of aluminum foil. Tape’s carrier combines glass cloth with a laminate of aluminum foil. The tape’s backing: 7um foil / FR glue / 110gsm glass cloth 12×12), coated with a high performance glue, protected by an easy-release silicone release paper.

Aluminum foil glass cloth tape coating a pressure sensitive adhesive, which has a smooth and flat surface of the composite aluminum foil, it adheres well to various surfaces and over irregular or uneven substrates. The reinforced aluminum foil tape is light and heat reflective, high vertical and horizontal tensile strength, airtightness, and good watertight sealing performance. Aluminum foil glass cloth tape is a chemical resistant, thermally conductive tape that performs consistently at temperatures ranging from -30°C to 120°C. 

Aluminum foil glass cloth tape provides high strength and reflectivity with excellent flexibility. Outstanding radiant heat reflectivity and thermal stability at extremely high temperatures. The combination of the aluminum foil and the fiberglass cloth provides superior heat resistance, making glass foil tape suitable for use in high-temperature applications such as wrapping ductwork, sealing heating and cooling systems, and protecting wires and cables from extreme heat.

Glass Foil Tape Applications:

HVAC industry for joining and sealing Foil-Scrim Facing laminated fiberglass blanket / duct board / pipe section joints and seams; joining and sealing flexible air duct seams and connections. May also be used for other industrial uses requiring a tape with these characteristics and benefits.

Glass Foil Tape Features: 

Aluminum glass cloth backing provides an excellent reflection of both heat and light.

High quality adhesive with super strong adhesion offers good sealing and bonding on Foil-Scrim Facing joints and seams in ductwork application.

The glass foil tape is an excellent vapor barrier due to low moisture vapor transmission rate.

Best result obtained when it’s applied to clean and dry surfaces without oil and grease.
