Description:
The Flame-retardant Foil-Glass Cloth Facing is a utility-grade composite facing material designed for insulation systems requiring high strength and flame retardancy. This product features a unique composite structure that laminates a thin aluminum foil to a high-strength fiberglass cloth using a flame-retardant adhesive. It not only possesses high tensile strength and exceptional tear resistance to withstand physical stress during installation and use but also acts as an effective vapor barrier, widely used as a protective outer layer for duct wrap, duct board, and pipe insulation.

Advantages:
- Exceptional Mechanical Strength
The fiberglass cloth core provides high tensile and tear resistance, ensuring durability and reducing damage risk during installation and service. - Reliable Flame Retardancy
The flame-retardant adhesive and composite design effectively inhibit flame spread, enhancing the insulation system's fire safety. - Excellent Vapor Barrier Properties
The dense foil layer blocks moisture ingress, preventing condensation-induced performance loss and corrosion.
Applications:
- HVAC Systems: Primarily used as the outer facing for duct wrap and duct board, providing protection and acting as a vapor barrier.
- Pipe Insulation: Used to wrap around various industrial and commercial pipe insulation materials (such as fiberglass or rock wool) serving as a protective and sealing layer.
- Industrial & Building Insulation: Suitable for the final protective layer on insulation systems for building envelopes and industrial equipment where specific strength or flame retardancy requirements exist.
