As an inventor of Aluminium Composite Material (ACP/ACM) 3A Composites is globally trusted. ALUCOBOND® A2 is a Non-Combustible ACP solution with Marine Grade Alloy for facades worldwide. Experience the power of Fire Safety with our High-Mineral filled Non-Combustible Core sandwich between two aluminum skins.

Why Choose ALUCOBOND A2?

With its non-combustible core, ALUCOBOND® A2 not only meets the most stringent fire regulations but also unleashes a world of creative possibilities. This marvel of innovation is more than just a facade – it's a gateway to design excellence

ALUCOBOND® A2 uses fluoropolymers for surface coating which makes it the preferred choice for long-term architectural use. Even after been in India for more than 25 years, no complain of shade fading till date. Inherently, its Marine Grade Alloy is corrosion-resistant and ensures durability in harsh corrosive environment.

Dreaming of towering high-rise buildings that stand as beacons of security? Seeking flawlessly protected office complexes, airports, or metro projects? Craving visually stunning shopping malls or hospitals that prioritize safety? ALUCOBOND® A2 is the answer to your aspirations.

From private homes to public landmarks, corporate headquarters to bustling industrial complexes, ALUCOBOND® A2 empowers designs like never before.



ALUCOBOND® A2 is the perfect blend of formability, flatness, stability, and weather resistance combined. Picture it as a second skin protecting the building and robustly embracing the essence of your building's design. Its composite structure unlocks a world of versatility, enabling the creation of awe-inspiring shapes and forms.


Harmony in Strength: The Fusion of Lightness and Rigidity

Due to its composite structure, ALUCOBOND® A2 possesses an extraordinary combination of strength and lightness, ensuring an impressive strength-to-weight ratio that remains unmatched, even for large panel sizes. It’s remarkable ability to maintain shape and flatness, even when subjected to extreme temperature fluctuations is a testament to its inherent rigidity. Moreover, the light weight of ALUCOBOND® A2 facilitates effortless transportation and handling adding convenience and ease.


Rear Ventilated System

With rear ventilated cladding system, ALUCOBOND® A2 offers unparalleled protection to buildings, shielding them from the harsh effects of solar radiations, weathering, industrial pollutants, and environmental hazards. The system creates a ventilated space that effectively reduces heat transmission and preserves the integrity of the structure.

Not only does ALUCOBOND® A2 safeguard the building's walls against extreme temperature fluctuations, but it also allows the moisture to pass through the rear space of the system. This helps in keeping the structure dry, ensuring long-lasting durability and performance.

The major advantages:

  • Drastically reduce maintenance costs
  • Safeguard the longevity of the building's structure for years to come
  • Enjoy substantial savings on heating costs during the winter season
  • Experience substantial reductions in air-conditioning expenses during summer
  • Minimize the risk of thermal expansion-related issues
  • Mitigate the occurrence of unsightly cracks in your building
