Fiberglass Cloth Aluminum Foil Tape

• Tape Description

  Constructed using an advanced multi-layer lamination process, this reinforced tape features a durable backing composed of 7µm aluminum foil, flame-retardant adhesive, and a 110gsm 12×12 glass cloth weave protected by an easy-release silicone liner. The woven fiberglass cloth supplies structural durability and high resistance to punctures and tearing, while the outer aluminum foil layer offers superior heat reflectivity and thermal conductivity.

  Formulated with a high-tack synthetic rubber-resin adhesive, Fiberglass Cloth Aluminum Foil Tape forms a durable barrier against air leakage, moisture ingress, dust, and environmental contaminants. Its flexible design allows it to conform effortlessly around corners and irregular surfaces, making it an essential solution for sealing HVAC ductwork joints, insulating high-temperature piping, shielding automotive engine compartments, and protecting sensitive electronics.

• Features & Benefits

  • High Heat Resistance & Thermal Reflection: The aluminum foil surface reflects radiant heat and manages thermal flow, ensuring reliable performance in high-temperature environments.
  • Durable & Tear-Resistant Construction: Integrated 110gsm fiberglass cloth reinforcement resists abrasion, mechanical wear, and accidental tearing under stress.
  • Protective Vapor Barrier: Acts as an airtight and watertight seal that prevents moisture transmission, dust, and air leakage.
  • Flexible & Conformable: Molds smoothly to uneven surfaces, curved pipes, and tight corners without lifting or buckling.
  • Easy Application: Features an easy-release silicone liner and a pressure-sensitive rubber-resin adhesive for quick, secure installation.

• Applications

  • HVAC Systems: Sealing duct joints and seams in heating, ventilation, and air conditioning equipment to prevent air leakage and improve energy efficiency.
  • Thermal Insulation: Wrapping pipe jackets and insulation materials to reflect radiant heat and optimize thermal performance.
  • Automotive Heat Shielding: Protecting sensitive components, hoses, and wiring from extreme temperatures in engine compartments.
  • Roofing & Construction: Providing waterproofing and thermal protection for structural joints exposed to elevated temperatures and outdoor elements.
  • Electronics Protection: Assisting in heat dissipation from active components and shielding sensitive electronics from electromagnetic interference

FAQ:

Q1. What is the backing construction of Fiberglass Cloth Aluminum Foil Tape?
A: The composite backing consists of a 7µm aluminum foil layer laminated to a 110gsm 12×12 fiberglass cloth weave using flame-retardant glue.

Q2. How does fiberglass cloth reinforcement improve performance compared to standard aluminum foil tape?
A: The woven fiberglass cloth backing provides significantly higher tensile strength and tear resistance, allowing the tape to withstand physical stress, abrasion, and punctures that would cause plain foil tape to rip.

Q3. Is this tape suitable for HVAC duct sealing?
A: Yes. It is commonly used to seal joints and seams in HVAC ductwork, creating an airtight, moisture-resistant bond that prevents energy loss.

Q4. Does this Aluminum Foil Tape conform well to irregular surfaces?
A: Yes. Despite its high strength, the tape remains flexible and conformable, allowing it to adhere smoothly around tight bends, pipe fittings, and textured surfaces.

Q5. Can this tape be used for heat shielding in engine bays?
A: Yes. Its reflective aluminum surface and heat-resistant properties make it ideal for protecting automotive wiring, hoses, and surrounding components from radiant heat in engine compartments.
