Aluminium adhesive tape
The ATyT aluminum adhesive tape is designed for technical applications requiring thermal resistance, durability and a high sealing capacity. Manufactured with an aluminum backing and a transparent water-based acrylic adhesive, this aluminum adhesive tape provides secure bonding and extra-strong adhesion on multiple surfaces used in industrial installations and technical systems.
The range is available in 30 µm, 40 µm and 50 µm thicknesses, allowing the most suitable solution to be selected according to the requirements of each application.
The 30 µm aluminum adhesive tape stands out for its flexibility and ease of conformability, making it ideal for duct sealing, HVAC system joints and applications requiring quick adaptation to curved or irregular surfaces.
The 40 µm aluminum tape offers an optimal balance between flexibility and mechanical strength, making it particularly suitable for general thermal insulation applications, insulation material protection and industrial maintenance. Meanwhile, the 50 µm aluminum adhesive tape provides greater robustness and tear resistance, making it the recommended option for more demanding applications, installations subject to mechanical stress or jobs requiring enhanced durability.
Thanks to its mechanical and thermal properties, the industrial aluminum tape maintains reliable performance even in demanding environments with temperature fluctuations, humidity or continuous industrial use. These characteristics make the thermal insulation tape a widely used solution in HVAC, ventilation and insulation material protection applications.
In technical insulation applications, the aluminum adhesive tape also acts as a vapor barrier, helping prevent moisture penetration and protecting insulation materials from condensation and premature deterioration. This property is especially important in thermal installations and industrial ventilation systems.
The industrial aluminum tape is also used for sealing thermoacoustic panels and insulation joints where a durable and resistant solution is required. Thanks to the combination of metallic backing and acrylic adhesive, the tape maintains excellent dimensional stability and outstanding adhesion on aluminum, steel, insulation panels and other technical surfaces.
The adhesive solutions developed by ATyT are designed to provide industrial performance, safety and compatibility for duct sealing, thermal insulation and technical protection applications in demanding professional environments.

- Apply the tape with uniform pressure during bonding
- Insufficient pressure may reduce mechanical performance and affect final appearance
Success case aluminium adhesive tape
Miguel contacted the ATYT team because he needed to improve the sealing of air conditioning ducts that he regularly installed. In some installations, he detected small air leaks and condensation problems at certain joints, which affected the energy efficiency of the system and caused issues later in the project.
After analyzing the application and materials used, our technical department recommended the ATYT aluminum adhesive tape, specifically designed for sealing applications, thermal insulation and vapor barrier in air conditioning and ventilation systems. We sent him a sample to validate its performance directly in one of his installations.
The results were very satisfactory. Thanks to its excellent adhesion, moisture resistance and ability to adapt to duct joints, the tape improved the installation's weatherproofing and strengthened the vapor barrier continuity. He now regularly uses it on air conditioning, ventilation and technical insulation projects, offering his clients a professional, reliable and durable solution.
Frequently Asked Questions
It is a versatile sealing and insulation solution with aluminum backing and water-based acrylic adhesive. It is mainly used in HVAC installations, thermal protection, duct sealing and industrial and construction applications.
Yes, and choosing the right thickness can make a difference in the final result. As a general rule, more microns means more resistance. But it depends a lot on what you're going to use it for.
If you work in air conditioning or HVAC, the 30 µm version is perfect for sealing ducts thanks to its flexibility. If the installation will have continuous use, move up to 40 µm. And if the system is especially demanding, the 50 µm version will give you maximum durability.
In construction, 30 µm works well for sealing joints between panels and vapor barriers. The 40 µm is ideal when you also need resistance during installation, for example in thermal or acoustic insulation. The 50 µm is designed for high-demand projects where you can't afford the tape to fail.
For industrial applications, 30 µm covers quick repairs and light sealing. The 40 µm is the most versatile option for general industrial use. And if conditions are severe, the 50 µm version will give you the robustness you need.
If you're unsure, the 40 µm is usually the most balanced option for most professional work. Are you not sure which one is right for you? Ask us and we'll help you choose
ATYT offers this tape in three thicknesses:
- - 30 μm — Greater flexibility and adaptability. Ideal for light sealing, trims and applications where conformability over irregular surfaces is prioritized.
- - 40 μm — Balance between flexibility and mechanical resistance. Intermediate option for HVAC installations, appliances and construction with higher durability requirements.
- - 50 μm — Greater thickness and rigidity. Recommended for demanding industrial applications where greater tear resistance, intensive handling or reinforced mechanical protection is required.
Yes. Its service range of -20 °C to +120 °C makes it suitable for the typical operating ranges in air conditioning systems, both for cooling and heating. Acrylic adhesive is more thermally stable long-term than rubber, making it preferable to cloth or cloth-backed tapes for permanent duct seals.
Yes. All three formats have a fire propagation index of 2.80, Class 0 according to BS 476 Part 6 standard, suitable for installations with fire safety requirements.
Yes. Its acrylic adhesive is compatible with metal, plastic, fiberglass, glass and polycarbonate. Steel adhesion is ≥ 4 N/cm in all three thicknesses. The surface must be clean and dry to ensure optimal adhesion.
Yes, although the thicker the backing, the more difficult it will be to tear by hand. It is still recommended that applicators use cutting tools such as scissors or a craft knife to ensure a straight and precise cut.
All three thicknesses are supplied in widths from 12 to 1200 mm and lengths from 5 to 500-1,000 m.
