Smooth Aluminium Cladding For Insulation

2025-07-29

Smooth aluminium cladding are commonly used in pipes, construction, cold chain transportation, air conditioning systems and other areas for insulation and moisture protection. Their smooth surface enhances reflectivity, reduces heat transfer, and thus improves insulation effectiveness. These aluminum cladding sheets are typically made of high-quality aluminum alloy, offering excellent corrosion resistance and strength, making them suitable for use in a variety of environments. They are often coated with an inner layer of insulating material, such as polyurethane or polyethylene, to further enhance their thermal performance.

The specification of smooth aluminum cladding for insulation produced by Haomei Aluminum:
- Grades:
Commonly used are 1060 (industrial pure aluminum), 3003 (aluminum-manganese alloy with excellent rust resistance), and 5005 (aluminum-magnesium alloy with high corrosion resistance).
- Thickness:
Common thicknesses range from 0.2mm to 1.2mm, with some manufacturers offering thicknesses up to 3.0mm.
0.3mm, 0.5mm, and 0.8mm are the most commonly used specifications for pipe insulation. 0.5mm is the most widely used due to its balance of strength and cost-effectiveness.
Aluminum cladding roll with a thickness of 1.0mm to 1.5mm may be used for building exteriors or in highly corrosive environments. For special applications (such as ultra-low-temperature equipment), custom 0.17mm ultra-thin aluminum foil can be supplied.
- Width:
Standard stock widths are 1000mm, 1220mm, and 1500mm, with some manufacturers offering customization from 800mm to 1900mm.
- Length:
Typically supplied in rolls, with small rolls ranging from 20 to 50 meters (for ease of installation) and large rolls ranging from 1800 to 2200 meters (suitable for bulk purchases).

Smooth aluminum cladding roll can be laminated with poly-Surlyn film (such as polyethylene film) or Poly-kraft paper to enhance moisture resistance. This composite material effectively blocks moisture penetration, further improving insulation performance. The following are some specific advantages and applications:

1. Poly Surlyn Film
- Moisture Resistance: Surlyn film offers excellent moisture resistance, effectively preventing water vapor penetration, protecting the insulation material from moisture and maintaining its thermal insulation effectiveness.
> - Durability: Surlyn film generally offers good temperature resistance and corrosion resistance, making it suitable for use in a variety of environments. Lightness: After being laminated with aluminum sheet, the overall material remains relatively lightweight, making it easy to install and handle.

2. Poly Kraft Paper
- Economy: Kraft paper is a relatively economical material suitable for large-scale applications.
- Processability: Kraft paper is easy to process and bond, and can be cut into various sizes and shapes as needed.
Environmental friendliness: Kraft paper is a biodegradable material and is environmentally friendly.

Smooth aluminium cladding for insulating has been widely used in various fields due to its unique properties and functions. The following are some of its key advantages:

1. Excellent Thermal Insulation
- Heat Reflection:
The smooth and highly reflective surface of aluminum cladding roll effectively reflects heat, reducing heat conduction and improving insulation effectiveness.
- Reduced Heat Loss:
In buildings, cold chain transportation, and air conditioning systems, aluminum cladding sheet can significantly reduce heat loss and improve energy efficiency.

2. Moisture Resistance
- Water Vapor Barrier:
Aluminum cladding itself does not easily absorb water, effectively blocking water vapor penetration, preventing moisture from entering the insulation material and maintaining its performance.
- Corrosion Resistance:
Aluminum has excellent corrosion resistance, making it suitable for use in humid environments and extending its service life.

3. Lightweight and Easy Processing
- Lightweight:
Aluminum insulation cladding is lightweight, making it easy to transport and install, reducing the construction burden.
- Easy Processing:
It can be cut, bent, and formed as needed to adapt to different application scenarios.

4. Durability
- Oxidation Resistance:
Aluminum easily forms an oxide film on its surface, providing strong weather resistance and resistance to various environmental factors.
- High Strength:
Aluminum cladding sheeting has excellent mechanical strength and can withstand certain external forces and pressures.

5. Environmental Protection
- Recyclability:
Aluminum is recyclable, meeting environmental protection requirements and reducing environmental impact.
- Low Energy Consumption:
Using insulating aluminum cladding can reduce energy consumption and carbon emissions, aligning with sustainable development.

Applications of smooth aluminium cladding:
- Building Insulation:
In the insulation layer of building exterior walls, roofs, and pipes, composite materials can effectively improve moisture resistance and extend service life.

- Cold Chain Transportation:
During refrigerated transportation, composite materials can ensure stable temperature of goods and prevent moisture from affecting their quality.

- Air conditioning systems:
Composite materials can prevent condensation in the insulation of air conditioning ducts and equipment, thereby improving the system's energy efficiency.

In general, smooth aluminium cladding, with its excellent thermal insulation, moisture resistance, lightweight design, and durability, has become an indispensable material in various insulation projects.
