Aluminum Foil Glass Cloth Tape

Tape Description

In high-temperature industrial operations, standard insulation tapes frequently degrade due to thermal stress, mechanical abrasion, or environmental exposure. Aluminum Foil Glass Cloth Tape combines the high reflectivity of pure aluminum foil with the structural integrity of heavy-duty woven fiberglass.

Featuring a specialized multi-layer architecture—incorporating a 7µm aluminum foil layer laminated to a 110gsm fiberglass cloth—this high-strength material resists tearing, punctures, and mechanical wear during handling and long-term service. The outer aluminum barrier reflects radiant heat and prevents moisture, oil, and chemical ingress, while the flexible fiberglass matrix provides structural stability over irregular surfaces, pipes, and complex joint geometries. Whether used for HVAC duct sealing or engine bay thermal shielding, SLAA Aluminum Foil Glass Cloth Tape ensures consistent protection and energy efficiency.
Features & Benefits
- Superior Heat Insulation: The highly reflective aluminum foil layer blocks radiant heat transfer, optimizing energy conservation for thermal ductwork, piping, and sensitive electronic assemblies.
- Flame Resistance: The non-combustible woven glass cloth backing provides robust flame retardancy, ensuring safety compliance in high-risk thermal environments.
- High Mechanical Durability: Built with a 7µm aluminum layer and 110gsm glass cloth backing, the tape resists physical wear, tearing, and puncture forces during installation and long-term use.
- Moisture & Chemical Resistance: Shields underlying substrates against ambient moisture, vapor transmission, harsh chemicals, solvents, and outdoor UV exposure.
- Electrical & Thermal Insulation: Offers secondary dielectric and thermal protection for wiring harnesses, cables, and sensitive machinery components.
- Flexible & Conformable Handling: Highly conformable backing allows effortless wrapping and secure adhesion around curved, uneven, or complex structural profiles.

Applications

- HVAC Systems: Seals and insulates hot and cold air ductwork, joint seams, and fiberglass board facings to maximize thermal efficiency and reduce operating energy loss.
- Aerospace & Automotive: Serves as a radiant heat shield for engine compartments, exhaust vicinity wiring, firewalls, and critical aircraft cabling.
- Construction & Building Envelope: Used for joining, patching, and sealing aluminum foil glass cloth insulation facings in commercial and industrial structures.
- Electrical Equipment Insulation: Wraps and insulates electrical wire harnesses, power distribution cables, and electronics requiring high-temperature protection and flame resistance.
- Industrial Thermal Shielding: Ideal for harsh manufacturing environments where heat resistance, flame retardancy, and chemical immunity are required to maintain operational safety.

FAQ:

Q1. What is Aluminum Foil Glass Cloth Tape made of?

A: It is a multi-layer composite tape made by laminating a 7µm aluminum foil layer to a 110gsm reinforced fiberglass cloth backing, coated with a high-tack pressure-sensitive adhesive.
Q2. What temperature range can aluminum glass cloth tape withstand?

A: SLAA Aluminum Foil Glass Cloth Tape is formulated to maintain structural integrity and adhesive strength across operating service temperatures from -30°C to 120°C.
Q3. How does the fiberglass layer improve performance over standard foil tape?

A: The woven glass cloth layer drastically increases tensile strength and tear resistance, preventing the tape from ripping during high-tension wrapping over sharp or irregular surfaces.
Q4. Is Aluminum Foil Glass Cloth Tape suitable for outdoor applications?

A: Yes. The aluminum foil facing provides excellent resistance to UV radiation, moisture, vapor, and harsh weather conditions, making it suitable for both indoor and outdoor industrial installations.
