1. Why Aluminum Roll Jacketing with Polysurlyn Moisture Barrier was widely used as cladding for pipe insulation?
Aluminum Roll Jacketing with a Polysurlyn moisture barrier is used for pipe insulation to provide superior, long-term protection against its two main enemies: moisture and physical damage.
The Polysurlyn layer acts as an exceptional moisture barrier. Its key advantage is that it can be heat-welded at the seams, creating a continuous, monolithic seal that prevents water vapor from penetrating the insulation. This is critical, as moisture drastically reduces thermal efficiency and causes corrosion under insulation (CUI).
The outer aluminum layer provides a durable shell that protects against impact, abrasion, UV radiation, and weather. It also adds fire resistance and a reflective finish.
Together, they form a synergistic system: the aluminum acts as tough armor, while the sealed Polysurlyn underneath guarantees a dry interior. This combination ensures the insulation performs efficiently for decades, making it ideal for outdoor, high-humidity, or corrosive environments.
2. What is the polysurlyn film on aluminum coils?
A composite film with a Surlyn (ionomer) core layer, known for low water vapor transmission and resistance to pinholing, often specified for ASTM C1729 compliance.
Total film thickness around 76 microns (3 mils), with reported water vapor permeability <1.55 g/m²/day.
3. Functions of polysurlyn film on aluminum coils:
Reduces water vapor ingress, protecting the aluminum jacket and underlying insulation from moisture-related degradation.
Improves corrosion resistance, especially in wet or aggressive environments (e.g., coastal, industrial).
Offers better tear and abrasion resistance during handling and installation compared to paper barriers.
Laminated by hot pressing at ~140°C after degreasing and surface preparation; film is usually blue and bonds firmly even after water immersion tests.
Insulation jacketing for hot and cold pipes, tanks, and vessels in oil & gas, power, chemical, and refrigeration facilities.

Mechanical Insulation:
Pipe Insulation: Aluminium barrier rolls are commonly used to wrap pipes, protecting the insulation material from moisture, weathering, and mechanical damage. This is crucial for maintaining the integrity and efficiency of the insulation system, preventing energy loss and damage to the pipes.
Duct Insulation: In HVAC systems, aluminium barrier rolls are used to insulate rectangular ducts, preventing condensation, improving energy efficiency, and ensuring a comfortable indoor environment. They provide a barrier against moisture and protect the insulation material from damage, extending the lifespan of the HVAC system.
Tank Coverings: Aluminium barrier rolls are also used to cover tanks and vessels, protecting the insulation material from external elements and preventing corrosion. This is essential for maintaining the temperature and pressure inside the tank, ensuring safe and efficient operation.
Protective Coatings:
VCI Coatings: Some aluminium barrier rolls are coated with Volatile Corrosion Inhibitors (VCIs), which release chemicals that prevent corrosion on metal surfaces. This makes them ideal for protecting stored goods, equipment, and metal components during transportation and storage.
Reflective Coatings: Reflective aluminium barrier rolls are designed to reflect heat and reduce radiant heat transfer. They are commonly used in applications where temperature control is critical, such as in industrial ovens, refrigeration units, and solar reflective applications.
Other Applications:
Automotive Industry: Aluminium barrier rolls are used in the automotive industry for applications such as heat shields, exhaust systems, and underbody protection. Their lightweight and durability make them ideal for withstanding extreme temperatures and harsh conditions.
Marine Industry: In the marine industry, aluminium barrier rolls are used for applications such as boat hulls, fuel tanks, and machinery enclosures. Their resistance to corrosion and sea water makes them suitable for withstanding the challenging marine environment.
Construction Industry: Aluminium barrier rolls find applications in the construction industry for cladding, roofing, and siding. Their durability, weather resistance, and aesthetic appeal make them a popular choice for enhancing the functionality and aesthetics of buildings.
Benefits of Aluminium Barrier Rolls:
Moisture Resistance: Aluminium barrier rolls provide an effective barrier against moisture, preventing water from reaching the insulation material and causing damage.
Corrosion Resistance: The aluminium material is naturally resistant to corrosion, protecting the insulation and underlying structures from rust and degradation.
Mechanical Strength: Aluminium barrier rolls offer good mechanical strength, protecting the insulation material from damage due to impact, vibration, and abrasion.
Flexibility and Ease of Installation: Aluminium barrier rolls are flexible and easy to install, allowing for efficient coverage of complex shapes and surfaces.
Lightweight: The lightweight nature of aluminium barrier rolls makes them easy to handle and transport, reducing installation time and costs.
Choosing the Right Aluminium Barrier Rolls:
When selecting aluminium barrier rolls, it’s important to consider factors such as:
