1. Efficient Thermal Insulation
Aluminum foil-coated fiber paper, thanks to the high reflectivity of aluminum foil (up to 95% or more) and the low thermal conductivity of fibrous materials, effectively prevents thermal radiation and heat transfer. For example, when aluminum foil-coated fiberglass cloth is used in heating networks, the surface temperature of pipes is reduced by an average of 4°C, and heat loss decreases by 40 kcal/m²·h, which, over long-term operation, can save up to 5 tons of standard fuel per 100 m².
The dense structure of the aluminum foil prevents air convection, further enhancing insulation properties, making the material suitable for insulating high-temperature equipment (such as boilers and cracking furnaces).

2. Moisture Protection and Corrosion Resistance
Aluminum foil itself is impermeable to air and water, and when combined with fibrous materials, forms a double protective barrier. For instance, aluminum foil-coated fiberglass cloth uses a middle layer of polyethylene with heat sealing, ensuring extremely low vapor permeability and reliably protecting insulation materials such as glass wool from property degradation caused by moisture.
The surface is treated with a special anti-corrosion coating with high resistance to aggressive environments, allowing the material to be used in chemical pipelines, oil pipelines, and other corrosion-prone conditions.

3. Mechanical Protection
Fibrous materials (such as fiberglass) provide high tensile strength in both longitudinal and transverse directions, giving aluminum foil-coated fiber paper excellent mechanical strength. For example, aluminum foil-coated fiberglass cloth surpasses reinforced aluminum foil in strength and is widely used for online lamination in the production of glass wool and stone wool, protecting insulation from mechanical damage.
Reinforced aluminum foil with strengthened fiberglass ribs increases structural stability and is often applied in the external wrapping of pipe insulation, preventing mechanical damage during installation and operation.
