Product Structure

Aluminum foil layer: Typically a soft aluminum foil approximately 7 microns thick, specially treated to provide excellent barrier properties that effectively block the transmission of water vapor and heat.
Kraft paper layer: Typically made from 55 gsm kraft paper, which provides adequate strength and stiffness while enhancing the product’s flatness and aesthetic appeal.
Glass fiber mesh layer: Typically a three-directional glass fiber-reinforced mesh, such as the 3D 816 glass fiber-reinforced mesh, with a standard mesh aperture of 5 mm × 5 mm. This layer provides reinforcement, enhancing the product’s tensile strength and tear resistance.
Heat-seal layer: A specialized polyethylene (PE) coating is applied to the back side of the product to serve as a heat-seal adhesive layer. Upon heating, this layer ensures strong bonding between the heat-seal reinforced aluminum foil and thermal insulation materials such as glass wool and rock wool.

Scope of Application

In the construction sector, it can serve as both a vapor barrier and an external protective layer in exterior wall insulation systems, as well as for roof thermal insulation and floor insulation, effectively enhancing the thermal performance of buildings and reducing energy loss.
HVAC field: Commonly used for thermal insulation and vapor barrier protection of air-conditioning ducts and chilled/hot water pipes. When combined with insulation materials such as glass wool and rock wool, it can prevent condensation on pipe surfaces and enhance the energy efficiency of air-conditioning systems.
Industrial insulation applications: It can be used as an external protective wrapping material for the insulation layers of industrial equipment, pipelines, and other components, such as petrochemical pipelines and steam pipelines, providing thermal insulation, moisture resistance, and corrosion protection to extend the service life of equipment and pipelines.
Electronics sector: Can be used for packaging electronic devices to provide moisture and electrostatic protection, thereby safeguarding electronic components from damage.
