Aluminum Foil Insulation Tape

Professional 50µm Thermal Shielding & HVAC Vapor Barrier

Aluminum Foil Insulation Tape is a high-performance adhesive solution specifically engineered for the rigorous demands of the HVAC, construction, and industrial sectors. Featuring a 50µm aluminum foil backing, this tape provides a robust yet flexible barrier designed to optimize thermal efficiency and ensure airtight seals. It is the premier choice for professionals requiring a reliable foil tape for insulation that reflects radiant heat and prevents moisture ingress.

Description

Our aluminum foil tape combines the natural durability of heavy-duty aluminum with a high-performance synthetic rubber-resin adhesive. The 50µm thickness is precision-calibrated to offer maximum protection against heat, light, and moisture while maintaining the flexibility needed to conform to irregular or curved surfaces.

To ensure ease of use on the job site, the tape is backed by an easy-release silicone paper liner, allowing for quick measurement, cutting, and application. Once applied, it forms a permanent bond with both metallic and non-metallic substrates, maintaining its integrity across a wide environmental spectrum.
Tape Features
- High Thermal Reflectivity: The aluminum backing provides exceptional reflection of both heat and light, enhancing the energy efficiency of insulated systems.
- Industrial-Grade Adhesion: Equipped with a super-strong synthetic rubber-resin adhesive, it offers reliable holding power for Foil-Scrim-Kraft (FSK) facing joints.
- Superior Vapor Barrier: A low moisture vapor transmission rate (AFR5090) makes this an ideal aluminum foil tape for ductwork, preventing condensation and leaks.
- Extreme Temperature Resilience: Engineered for performance in diverse climates, the tape maintains a stable bond within a service temperature range of -20°C to +80°C.
- Quick Installation: The easy-release liner and high initial tack allow the tape to be applied quickly to a variety of surfaces, reducing labor time.

Tape Applications

HVAC Systems: Joining and sealing Foil-Scrim-Kraft Facing laminated fiberglass blankets and duct board seams.
Ductwork Sealing: Providing an airtight seal for flexible air duct seams and hardware connections to improve system airflow.
Industrial Insulation: Protecting sensitive components from radiant heat and environmental moisture.
Construction & Repair: General-purpose sealing in industrial environments that require a high-strength, thermally conductive tape.

FAQ:

Q1: Why is 50µm the preferred thickness for insulation?
A: A50µm backing provides the ideal balance between structural durability and the flexibility required to wrap around corners and irregular duct shapes without tearing.

Q2: Can this tape be used on non-metal surfaces?
A: Yes. This Aluminum Foil Insulation Tape is formulated to adhere strongly to both metallic and non-metallic surfaces, including fiberglass and plastic composites.

Q3: Is this tape suitable for cold weather applications?
A: Absolutely. The synthetic rubber-resin adhesive is designed to remain effective at temperatures as low as -20°C to +80°C..

Q4: Does it act as a moisture barrier?
A: Yes. Its low moisture vapor transmission rate makes it a highly effective vapor barrier, protecting your insulation from moisture damage.

Q5. What makes this tape suitable for insulation?
A: The aluminum backing reflects heat while the adhesive seals gaps, improving overall insulation efficiency.
