A2 Non-combustible Wooden ACP: Technical Specifications and Compliance for Vietnam Public Projects

With the acceleration of urbanization in Vietnam, core public infrastructure in cities like Ho Chi Minh City and Hanoi—such as airport terminals, hospitals, schools, and large shopping malls—has placed higher demands on the safety of building materials. Especially with increasingly strict fire safety regulations, A2 Non-combustible Wooden Aluminum Composite Panels (ACP), combining superior fire resistance with timber aesthetics, are becoming the top choice for architects and contractors.

In Vietnam, fire safety codes for public gathering places (such as QCVN 06:2022/BXD) have significantly raised the fire rating requirements for exterior walls and interior ceilings.

While ordinary B1 fire-retardant materials can delay the spread of fire, they may still produce smoke or droplets under extreme conditions. The core of A2 Wooden ACP consists of over 90% inorganic minerals (such as magnesium hydroxide and aluminum hydroxide). In the event of a fire, the material remains "non-combustible," producing minimal smoke and zero toxicity, which is vital for evacuation safety in public buildings.

When conducting B2B selection, purchasers should verify the following parameters to ensure project stability and reliability:

• Parameter: Inorganic mineral filling rate ≥ 90%.

• Performance: Tested according to EN 13501-1 or ASTM E84 standards. A2 grade means virtually zero heat release during a fire, effectively preventing vertical flame spread.

• Process: Utilizing triple-layer PVDF roller coating technology.

• Durability: Coating thickness should be ≥ 25μm. This ensures that the wood grain texture remains resistant to visible color shifts ($Delta E leq 5$) for over 20 years under Vietnam’s high-humidity and high-UV environment.

• Data Support: 180° peeling strength should be ≥ 9.0 N/mm (for 4mm/0.50mm specifications).

• Significance: Even under high-temperature conditions, the aluminum skin and fireproof core maintain excellent bonding, preventing facade panels from detaching during extreme weather or disasters.

Vietnamese culture has a profound preference for wooden elements. However, natural timber is flammable, prone to decay, and requires high maintenance, making it difficult to meet the requirements of modern large-scale public construction.

A2 Wooden ACP achieves "metal performance with a timber look." It does not require regular fire-retardant spraying or anti-corrosion treatments like solid wood. For large commercial complexes in areas like Long Bien District (Hanoi) or Thu Duc City (HCMC), this "maintenance-free" feature significantly reduces long-term operational costs.

As a recyclable metal composite material, A2 ACP aligns with modern green building certifications. Precision-printed textures simulating Oak, Walnut, or Teak allow for a warm, high-end visual experience while reducing the consumption of natural timber resources.
