Polishment High Density Fiber Cement Board – Durable, Fireproof, and Eco-Friendly Building Material

Polishment high density fiber cement board is an advanced building material manufactured from natural cement, refined sand, and wood fiber, offering exceptional strength and environmental safety. This board is engineered to meet the demands of modern construction, providing a non-combustible solution with a density ranging from 1.2 to 1.5 g/cm³. With an anti-bending strength of ≥12MPa and a low swelling ratio of ≤0.25%, it ensures long-term dimensional stability and structural integrity for both residential and commercial projects.

Polishment high density fiber cement board delivers outstanding fire protection, achieving Class A1 incombustibility under GB8624-1997 and providing over 240 minutes of fire resistance. This makes it an ideal choice for applications where safety is critical, such as schools, hotels, stadiums, and office buildings. Unlike traditional materials, this board contains 100% no asbestos, meeting international health and safety standards while offering reliable performance in high-temperature environments.

Polishment high density fiber cement board is designed for superior moisture resistance, with a water content ratio of ≤10% and water absorption (plain) of ≤30%. After 24 hours of water exposure, the reverse side may show a water mark but will not form droplets, demonstrating excellent water tightness. This characteristic, combined with its frost resistance (no cracking or delamination after 25 freeze-thaw cycles), makes it suitable for humid areas like washing rooms, tunnels, and exterior cladding in varying climates.

Polishment high density fiber cement board offers remarkable durability and impact resistance, maintaining integrity without continuous cracking after sudden shocks. Its high density contributes to excellent acoustic insulation, weather resistance, and thermal insulation, helping to reduce energy costs and noise pollution. The board also resists antisepsis and moth damage, ensuring a long service life of more than 50 years with minimal maintenance, as highlighted in the product characteristics.

Polishment high density fiber cement board is available in multiple standard sizes, including 1220×2440mm, 1200×2400mm, 1200×3000mm, and 1220×3000mm, with thickness options from 5mm to 12mm. Custom sizes can be produced upon order, providing flexibility for partition walls, suspended ceilings, exterior wall cladding, lightweight grouting panels, and interior dry wall decoration. The board can be easily cut, nailed, and installed like gypsum board, saving time and labor costs on construction sites.

Polishment high density fiber cement board carries full certifications including ISO and SGS, complying with JC/T412-2006 and GB6566-2001 (A-class decoration materials for radioactivity). The product is exported using standard wooden pallet packaging, with trade terms such as FOB, CNF, CIF, and CFR available. Payment methods include T/T, L/C, and D/P, with delivery typically completed within 10 days. With a monthly production capacity of 200,000 pieces, the supply chain is reliable for large-scale export orders.

Polishment high density fiber cement board is proudly produced by one of China’s earliest and most experienced manufacturers of calcium silicate and fiber cement boards. The Aierjia brand has been awarded “Fine-Quality, Famous-Brand Products in China” and is exported to the UAE, Saudi Arabia, Qatar, Spain, Australia, South Korea, Italy, and Southeast Asia. Whether used for exterior walls (hotels, villas, supermarkets) or interior walls (subways, meeting rooms, corridors), this board provides a green, high-strength, and cost-effective solution for global builders and architects.
