Insulation Facing Description

 

Aluminum Foil Laminated Fiberglass Cloth(18u foil and 8×8 mesh glass cloth, laminated with F/R glue). This insulation facing enjoys good abrasive-resistance and high tensile strength, UL 723 & BS 476 Pt 6&7 Fire rating approval.

Heat Insulation: The aluminum foil layer in the composite material serves as a radiant heat reflector, helping to block heat transfer. This makes aluminum foil laminated fiberglass cloth an effective material for thermal insulation applications, such as insulating pipes, ducts, and equipment in high-temperature environments.

Fire Resistance: Fiberglass cloth is inherently fire-resistant, and when combined with aluminum foil, the composite material exhibits enhanced fire resistance properties. This makes it suitable for use in fireproof barriers, fire curtains, and other applications where fire protection is required.

Moisture Barrier: The aluminum foil layer provides a moisture barrier, preventing the penetration of water vapor and moisture. This feature is beneficial in applications where moisture resistance is needed, such as HVAC duct insulation and outdoor insulation applications.

Chemical Resistance: Aluminum foil laminated fiberglass cloth is generally resistant to many chemicals, making it suitable for use in environments where exposure to chemicals or corrosive substances is a concern.

Thermal Conductivity: The combination of aluminum foil and fiberglass cloth results in a material with low thermal conductivity. This property helps in maintaining temperature stability and energy efficiency in applications where thermal insulation is critical.

Aluminum Foil Laminated Fiberglass Cloth provides three valued insulation solutions: thermal protection, vapor barrier, and flame retardant. Excellent for HVAC thermal insulation and building thermal insulation. Very good for industrial and vessel engine room’s thermal insulation.Aluminum Foil Laminated Fiberglass Cloth is good as a vapor barrier of duct wrap, duct board and pipe insulation.
