Product Introduction

5x5 embossed aluminum foil faced is an aluminum foil composite product featuring a regular 5mm x 5mm embossed pattern on its surface. Its primary function is to provide protection and enhance the performance of insulation materials such as rubber-plastic and glass wool, making it widely used in pipelines, equipment, and building insulation systems.

Core components

Substrate layer: Mostly high-purity aluminum foil (typically with a purity of ≥99.5%), usually ranging in thickness from 0.03 to 0.08 mm, ensuring excellent ductility and heat resistance.
Embossed layer: Using a specialized mold, a 5mm × 5mm grid, diamond, or square pattern is pressed into the surface, enhancing its scratch resistance and creating a sense of depth—while also minimizing deformation in the aluminum foil caused by thermal expansion and contraction.
Composite/Coating Layer: Some products have a polyethylene (PE) film, fiberglass fabric, or an anti-corrosion coating laminated onto the back of the aluminum foil, enhancing adhesion, moisture resistance, and corrosion protection to meet the bonding requirements of various insulation substrates.

Key Performance

1. High Protection: The embossed 5mm × 5mm structure enhances the strength of the aluminum foil surface, effectively resisting friction and impacts during construction and daily use, thus preventing damage to the foil. At the same time, it creates a barrier that keeps external moisture and dust from penetrating deep into the insulation material, ensuring long-lasting thermal performance.
2. Enhanced Thermal Insulation: Aluminum foil inherently boasts a high reflectivity (up to over 85% for infrared radiation), which helps minimize heat transfer via radiation. Combined with its embossed structure that effectively blocks air movement, this design boosts the overall thermal insulation efficiency of the system by 10%–15%.
3. Weather- and Corrosion-Resistant: The pure aluminum substrate boasts excellent chemical stability. Combined with a composite back layer or anti-corrosion coating, it can maintain reliable performance across a temperature range of -40°C to 120°C, offering superior resistance to aging and protection against acid and alkali corrosion—making it ideal for both indoor and outdoor applications.
4. Easy to Install: The product boasts a flexible texture, allowing it to be effortlessly bent and cut to fit the shape of insulation materials—whether pipes or panels. Additionally, its embossed pattern enhances adhesion to the insulation material, making it simple and quick to secure using adhesive or tape.

Applicable Scenarios

Insulation material accessories: As an external facing for rubber and plastic insulation pipes, as well as glass wool boards or felts, it is used to provide thermal protection for air conditioning ducts, chilled and hot water pipes, and industrial equipment pipelines. Commonly found in commercial buildings, factories, hotels, and other similar settings.
Architecture field: Used as the outer protective layer for building exterior wall insulation, the moisture-proof layer in rooftop insulation systems, or as an interior wall protection material for cold storage facilities and cleanrooms—balancing both thermal insulation and cleanliness requirements.
