Standard 4mm ACP sheet weighs approximately 5.5 kg per square metre (with 0.50mm aluminium skins). 3mm ACP weighs about 3.8-4.2 kg/sqm, and 6mm ACP weighs about 7.5-8.0 kg/sqm. This makes ACP 8-10 times lighter than granite (40-60 kg/sqm) and 5 times lighter than glass curtain wall systems (25-40 kg/sqm).
| Thickness | Skin Thickness | Weight (kg/sqm) |
|---|---|---|
| 3mm | 0.25mm | 3.8 kg |
| 3mm | 0.50mm | 4.2 kg |
| 4mm | 0.30mm | 4.8 kg |
| 4mm | 0.50mm | 5.5 kg |
| 6mm | 0.50mm | 7.5 kg |
| Material | Weight (kg/sqm) | vs ACP |
|---|---|---|
| ACP 4mm | 5.5 | Baseline |
| Granite (30mm) | 45-60 | 8-10x heavier |
| Glass Curtain Wall | 25-40 | 5-7x heavier |
| HPL | 8-12 | 1.5-2x heavier |
| GRC | 15-25 | 3-4x heavier |
| Ceramic Tiles | 20-30 | 4-5x heavier |
Lighter facade materials reduce structural steel requirements, foundation loads, and transportation costs. For high-rise buildings, every kg/sqm reduction across thousands of square metres translates to significant structural savings. ACP's lightweight nature also enables faster installation — reducing project timelines and labour costs.
An Aluminium Composite Panel (ACP) is a flat panel consisting of two thin coil-coated aluminium sheets bonded to a non-aluminium core material, typically polyethylene (PE), mineral-filled fire-retardant (FR), or aluminium honeycomb. ACP panels are used for building facades, signage, interiors, and architectural cladding due to their lightweight, weather resistance, and design versatility.
Read full answer →ACP stands for Aluminium Composite Panel. It is also referred to as ACM (Aluminium Composite Material) or ACCP (Aluminium Composite Core Panel) for fire-rated variants. VIVA manufactures standard ACP, FR B1 fire-rated ACP, and FR A2+ ACCP with aluminium corrugated core.
Read full answer →For exterior cladding, PVDF-coated ACP with 70% KYNAR 500 resin is the best choice. VIVA recommends 4mm PVDF panels for standard exteriors and 4mm/6mm FR A2+ ACCP for buildings above 15 meters. The Solid & Metallic, Natural Stone, Premium Marble, and Mirage Fluted series are the most popular for exterior facades.
Read full answer →Yes, ACP sheets are waterproof. The aluminium skins and PVDF/PE coating create a moisture-impervious surface that does not absorb water, swell, or degrade with water exposure. ACP panels are ideal for exterior facades, monsoon-prone regions, and humid environments. However, proper sealing of panel joints with weather-grade silicone sealant is essential for a watertight facade system.
Read full answer →PVDF (Polyvinylidene Fluoride) is a high-performance coating used on ACP panels for exterior applications. Made with 70% KYNAR 500 resin, PVDF coating provides 25+ year colour retention, superior UV resistance, chemical resistance, and self-cleaning properties. VIVA uses PVDF coating on all exterior-grade ACP panels manufactured on Korean precision lamination lines.
