Aluminum tape Aluminio 353, 48 mm x 50 m PA-3530011-0048050

Application and Key Features in HVAC Installations

This 48 mm wide, 50 m long aluminum tape is a dedicated solution for assembly work in ventilation, air conditioning, and thermal engineering systems. Its primary function is to join, repair, and seal insulation mats and segments with aluminum jackets. Reinforced with a 5 mm x 5 mm fiberglass mesh, this material exhibits significantly higher mechanical strength compared to standard aluminum tapes. This is crucial for outdoor applications or in areas exposed to mechanical damage during operation.

The product is suitable for both indoor and outdoor installations. Its construction enables effective masking of joints and repair of damaged insulation sections. A key feature is its ability to conform to uneven surfaces – the tape adheres well even where the substrate is not perfectly smooth, eliminating the risk of gaps and thermal bridges.

Durability and Weather Resistance

High manufacturing quality results from the use of a reinforcing interlayer that prevents material tearing during stretching or due to system vibrations. The tape features a wide operating temperature range:

• Continuous operation: up to +120°C – allows use near hot pipes or in heating systems.
• Cold resistance: maintains adhesion at low temperatures, preventing detachment during freezing conditions, which is essential for outdoor installation.

The material is resistant to atmospheric factors, including UV radiation and ozone. Consequently, it does not undergo rapid aging or degradation due to sun exposure or rain. It also provides an effective barrier against moisture and contaminants, protecting the insulation layer from dampness. Additionally, the aluminum surface reflects heat and solar radiation, supporting the energy efficiency of the entire installation.

Construction Characteristics and Operational Properties

The key element of this tape is the 5x5 mm fiberglass mesh, which acts as the material's skeleton – it is responsible for high tensile strength and resistance to mechanical damage during installation or subsequent operation. This construction makes the product suitable for joining heavier insulation mats and for repairs in areas subject to high loads.

The operating temperature range up to +120°C allows safe use of the tape in direct proximity to hot components of heating systems or ventilation ducts transporting warm air. At the same time, the material retains flexibility and adhesion at low temperatures, facilitating installation work carried out in autumn or winter without the risk of tape detachment after several days of frost.

Thanks to its properties of reflecting thermal and solar radiation, the tape not only seals joints but also supports the thermal efficiency of the entire insulation system. Resistance to atmospheric factors (UV, ozone) ensures it can be permanently used outdoors without concern for rapid aging of the adhesive coating or the outer metal layer.
