ASJ Facing introduction
（Aluminum Foil/Scrim/Kraft）
Products Description
ASJ Facing refers to a type of facing material commonly used in insulation systems. The acronym “ASJ” stands for Aluminum/Scrim/Kraft, representing its key components. This facing material combines layers of aluminum foil, a reinforcing scrim (often made of glass fiber), and a layer of Kraft paper.
Composition:
- Aluminum Foil: Provides excellent thermal insulation properties, serving as a reflective layer.
- Scrim (Glass Fiber): Reinforces the facing material, enhancing strength and durability.
- Kraft Paper: Adds structural support and contributes to the overall robustness of the facing.

Function
ASJ Facing serves multiple functions within insulation systems:
1.Thermal Insulation: The aluminum foil layer effectively reflects and reduces heat transfer, contributing to thermal insulation.
2.Strength and Durability: The inclusion of scrim and Kraft paper enhances the facing’s strength, making it resilient during installation and usage.
3.Moisture Resistance: The aluminum foil provides moisture resistance, protecting the underlying insulation material from humidity and water ingress.
4.Flame Retardancy: ASJ Facing is often designed to be flame-retardant, enhancing the safety of the insulation system.
Applications
ASJ Facing finds widespread application in various sectors, including:
1.Building Construction: Used in insulation systems for walls, roofs, and floors to regulate temperature.
2.Piping Insulation: Applied to insulate pipes in industrial and commercial settings, providing thermal and moisture control.
3.HVAC Systems: Employed in air ducts and HVAC (Heating, Ventilation, and Air Conditioning) systems for thermal management.
4.Industrial Insulation: Utilized in diverse industrial applications where effective insulation is crucial.
