ALUMINIUM FOIL

STRUCTURE OF ALUMINUM FOIL (ALU FOIL)

Aluminum Foil (ALU Foil) typically features a multi-layered structure composed of the following:

• Pure Aluminum Layer:
  With a thickness ranging from 7µm to 18µm, this layer reflects up to 97% of heat and infrared radiation, providing excellent thermal insulation.

• Reinforcement Layer:
  Usually made of fiberglass scrim, PE mesh fabric, or non-woven fiberglass, it enhances tensile strength and tear resistance, ensuring durability during installation and operation.

• Paper Layer:
  A thin paper layer helps bond easily to the surface of insulation materials such as Rockwool, fiberglass wool, PIR, PU, and phenolic foam, improving adhesion and finish quality.

APPLICATIONS OF ALUMINUM FOIL (ALU FOIL)

• Excellent Thermal Insulation:
  ALU Foil effectively reflects heat and minimizes thermal radiation from the sun or other high-temperature sources.

• Essential Insulation Accessory:
  ALU Foil is a crucial accessory for wrapping thermal insulation in HVAC ducts, insulated pipes, ceiling panels, walls, and roofs of industrial facilities, commercial centers, and residential buildings.
  When applied over mineral wool insulation, ALU Foil enhances durability and protects flexible ducts, insulated pipelines, and air-conditioning systems from damage and heat loss.

• Outstanding Performance:
  The main advantages of ALU Foil include heat reflection, insulation, energy savings, non-combustibility, and moisture resistance.
  These combined properties make it an ideal solution for thermal protection and energy efficiency in both industrial and civil construction projects.

MAIN FEATURES & KEY BENEFITS

1. Heat and Thermal Insulation:
   ALU Foil reflects up to 97% of radiant heat, reducing heat transfer through surfaces such as roofs, walls, and ventilation systems.
   This feature is crucial for maintaining temperature stability and energy efficiency.

2. Protection for Piping and Duct Systems:
   Commonly used as an outer wrapping layer for insulation on ducts and pipelines, ALU Foil enhances mechanical durability and maintains HVAC system performance.

3. Moisture and Fire Resistance:
   ALU Foil acts as a vapor barrier, preventing moisture penetration and providing excellent waterproofing.
   In addition, it is fire-retardant, contributing to overall safety in construction applications.

4. Wide Range of Applications:
   ALU Foil is suitable for factories, cold storage facilities, shopping centers, and residential buildings.
   Proper installation can significantly reduce monthly energy costs and create a more comfortable living and working environment.
