Aluminum foil facing, also known as aluminum foil insulation, is a laminate material with an outer-facing layer made of aluminum foil. This foil layer is bonded to a backing material. It enjoys high tensile strength and good abrasive-resistance, and BS 476 Class O Fire-Rating approval.
Aluminum foil facing is a versatile and effective material for a wide range of insulation applications, offering superior thermal performance, moisture resistance, and energy efficiency.
Thermal insulation: Aluminum foil facing reflects radiant heat, effectively reducing heat transfer through the material. This helps to improve the thermal insulation properties of the insulation system, keeping the interior space cooler in hot climates and warmer in cold climates.
Moisture resistance: The aluminum foil facing acts as a vapor barrier, preventing the passage of moisture and water vapor. This helps to protect the insulation material from moisture damage, mold growth, and corrosion, ensuring optimal performance and longevity.
Radiant barrier: The reflective properties of the aluminum foil facing make it an excellent radiant barrier, blocking up to 97% of radiant heat transfer. This can result in energy savings by reducing the need for heating and cooling systems to maintain a comfortable indoor temperature.
Aesthetic appeal: The shiny, reflective surface of the aluminum foil facing provides a clean and professional finish to the insulation system. It can enhance the visual appearance of the installed insulation and contribute to a modern and stylish aesthetic.
The insulation facing is commonly used in construction and insulation applications to provide thermal insulation, moisture resistance, and radiant barrier properties.
It also acts as a vapor barrier, preventing the passage of moisture and water vapor, which helps to improve the overall energy efficiency and performance of the insulation system.
Aluminum foil facing can provide a clean, aesthetically pleasing finish to insulation products and help protect the insulation material from external elements such as dust, dirt, and contaminants.
