Aluminum Cladding With Moisture Barrier

2025-11-26

Aluminum cladding with factory applied moisture barrier layer are composite materials that combine the lightweight and corrosion resistance of aluminum with the heat insulation and moisture proof performance of a polyfilm layer. Their core structure is " aluminum substrate + heat laminated moisture barrier layer," and they are widely used in pipe insulation, equipment protection and building exterior walls. Aluminum cladding typically use aluminum coils made of materials such as 1060, 3003, and 5005 as the substrate. Common factory applied moisture barrier layer materials include polykraft paper and polysurlyn film. Kraft paper is laminated to the aluminum cladding surface through hot pressing or adhesive bonding, effectively preventing external moisture penetration. Polysurlyn is a polymer film that is firmly bonded to the aluminum coil through hot pressing and has good weather resistance.

Structure of aluminum cladding with moisture barrier:
Material: Commonly used are 1060 pure aluminum (aluminum content ≥99.6%) or 3003 rust-resistant aluminum (containing manganese, resulting in higher strength).
Thickness: 0.2mm-1.0mm, with 0.5mm thickness being the mainstream choice for pipe insulation due to its balance between strength and cost.
Factory applied moisture barrier layer materials: Kraft paper and polysurlyn film, etc.
Surface: Can be smooth, stucco embossed, corrugated, etc.
> Processing performance: Aluminum cladding can be easily bent, stamped, and roll-formed, suitable for covering curved pipes and irregularly shaped equipment, with high construction efficiency.

Performance characteristics of aluminum cladding with moisture barrier:
- Moisture-proof and corrosion-resistant:
The moisture barrier layer effectively isolates moisture, preventing aluminum coils from direct contact with humid environments and oxidation corrosion, extending their service life. Suitable for high humidity or corrosive environments, such as oil pipelines and chemical equipment insulation.
- Excellent thermal insulation performance:
As an outer layer material, aluminum coils can effectively reflect heat, reduce heat loss, and improve insulation performance.
- Corrosion resistance:
Aluminum has good corrosion resistance and is suitable for use in various environments.
- Easy processing:
Aluminum cladding rolls with moisture barrier layers can be further processed, such as pressing into orange peel texture, diamond texture, etc., or pressing into specific shapes. The surface is flat, facilitating cutting and installation, reducing on-site processing steps.
- Strong adhesion:
The moisture barrier layer, composited using a hot-pressing process, such as bonding kraft paper and aluminum cladding rolls at high temperatures, shows no delamination even after 24 hours of immersion in water, demonstrating high bonding strength.
- Wide range of applications:
Widely used in building exterior walls, roofs, cold storage facilities, air conditioning ducts, and other locations requiring insulation and moisture protection.

Aluminum cladding with moisture barrier are primarily used for pipeline insulation, such as moisture and corrosion protection for pipelines in the petroleum, chemical, and power industries; also applicable to exterior wall insulation, roof waterproofing, and decorative panels in building construction; widely used in projects in humid regions such as the Middle East and Southeast Asia.
- Pipeline insulation projects
Scenario: Steam and cold water pipelines in the petroleum, chemical, and heating industries.
- Cold storage and air conditioning systems
Scenario: -25℃ cold storage walls, central air conditioning ducts.
- Building exterior walls and roofs
Scenario: Exterior walls of residential and industrial plants in humid areas.
