In the realm of modern construction, selecting materials that offer both safety and comfort is paramount. The Soundproof and Fireproof Calcium Silicate Board has emerged as a leading solution for architects and builders who refuse to compromise on quality. Manufactured to stringent standards like JC/T412-2006, this versatile building material, also known as fiber cement board, combines the inorganic strength of cement with the stability of silica and reinforcing fibers. Available in common sizes such as 1200mm2400mm and 1220mm2440mm, and a variety of colors including grey, white, red, and green, it provides a durable and aesthetically flexible option for any project. With a production capacity reaching 2,000,000 pieces per year, Aierjia ensures that high-performance building materials are readily available for the global market.

What is a Soundproof and Fireproof Calcium Silicate Board?

A Soundproof and Fireproof Calcium Silicate Board is a high-performance, autoclaved building material composed of siliceous materials, calcium materials, and reinforcing fibers . Unlike traditional gypsum boards, this fiber cement board is engineered through a chemical reaction process that occurs in high-pressure steam curing, resulting in a durable and stable product . It is designed to be a “green” building material, offering excellent performance in fire protection and acoustic insulation while remaining non-toxic and environmentally friendly. With a density typically ranging from 1.2 to 1.5 g/cm³, these boards provide a robust and solid feel, suitable for a wide range of demanding applications from industrial plants to commercial interiors .

Unmatched Fire Protection with A1 Non-Combustible Properties

When it comes to passive fire protection, the Soundproof and Fireproof Calcium Silicate Board stands in a class of its own. It achieves the highest possible fire rating, classified as A1 non-combustible material under standards like GB8624-1997 and EN 13501-1 . This means the board will not burn, contribute to the spread of flames, or emit toxic fumes or smoke when exposed to fire . With an impressive fire resistance duration of up to 240 minutes, these boards are ideal for fire-rated assemblies, including firewalls, elevator shafts, stairwell enclosures, and structural steel protection . The inorganic nature of the material ensures that it provides a critical barrier, containing fire and allowing valuable time for safe evacuation.

Superior Acoustic Performance for Noise Reduction

In environments where peace and quiet are essential, the Soundproof and Fireproof Calcium Silicate Board delivers exceptional acoustic insulation. Its high-density composition (1.2-1.5g/cm³) makes it an effective barrier against airborne sound transmission, such as conversations or traffic noise . When used in partition walls and floor systems, the mass of the board helps to dampen sound vibrations, significantly improving the acoustic comfort of hotels, hospitals, schools, and multi-family housing . For enhanced soundproofing, these boards are often combined with mineral wool infill within stud walls, creating a high-performance acoustic assembly that meets strict noise control standards .

Key Physical Properties and Technical Specifications

The performance of a Soundproof and Fireproof Calcium Silicate Board is backed by rigorous physical properties that ensure long-term reliability. With an anti-bending strength of ≥16MPa, these boards offer excellent structural rigidity and impact resistance . The material is also designed to withstand moisture, featuring a water content ratio of ≤30% and a swelling ratio of ≤40%, which prevents warping or delamination in humid environments . Furthermore, the product boasts high dimensional stability, ensuring that it remains flat and true over time, resisting cracking from seasonal temperature changes and providing a solid substrate for tiles, paint, or other finishes .

Diverse Applications Across Residential and Commercial Projects

The versatility of the Soundproof and Fireproof Calcium Silicate Board makes it suitable for virtually every part of a building. For interior applications, it serves perfectly as partition walls, ceiling panels, and tile backing boards in wet areas like bathrooms and kitchens due to its moisture resistance . In exterior applications, the board functions as durable sheathing, cladding, and soffits, offering weather resistance and protection against the elements . For flooring systems, thicker variants of this high-density board can be used as a robust underlayment or as a dry screed replacement, providing a stable base for floor finishes and even supporting underfloor heating systems .
