In modern buildings, the top area is often the most vulnerable part to heat and smoke during a fire. Flames and high temperatures can spread rapidly upwards in the building, posing a significant threat to structural safety and personnel evacuation. To ensure building safety and fire protection performance, it is crucial to select appropriate materials to protect the top structure.
The calcium silicate boards from New Element, with their outstanding fire resistance, insulation, and structural stability, have become an indispensable solution for ceiling protection. Their high-temperature stability, low heat conductivity, and lightweight, easy-to-process characteristics have made them widely used in commercial, industrial, and public buildings.
Fire Risks and Protection Challenges in Ceiling Areas
The main risks of the top structure in a fire come from the accumulation of heat and smoke. The flames always spread upwards, making the ceiling and the top supporting structure the first parts to be damaged in a fire.
• The threat of high-temperature environments to structures: The top structure can withstand temperatures of up to several hundred degrees Celsius during a fire. If the materials cannot effectively block the heat, it will cause the beams, columns, and ceiling systems to lose their strength rapidly.
• Smoke spread risk: The upper space is usually connected to the air circulation path. If the protective material is not fire-resistant, smoke and toxic gases can easily penetrate the ceiling and affect the safe evacuation of the lower area.
• Long-term reliability challenge: The ceiling material is exposed to humidity changes and thermal cycles over an extended period. If its thermal resistance is insufficient, it is prone to warping, cracking, and even collapse, thereby increasing the cost of subsequent maintenance.
Therefore, the top protective material not only needs to prevent flames and high temperatures during a fire, but also must maintain stability during long-term use. This is also an important reason why calcium silicate boards are highly favored in ceiling protection.

Why Calcium Silicate Boards Are Essential for Ceiling Protection
Calcium silicate boards can play a crucial role in top protection because of their inherently excellent fire resistance properties, which can enhance the overall safety level of the building's top in multiple ways.
1. High-temperature Tolerance
The temperature in a top-space fire is often extremely high, making it difficult for ordinary materials to maintain structural integrity. However, NEW ELEMENT calcium silicate boards can withstand temperatures up to 1200℃, maintaining their strength and shape stability. This means that in the event of a fire, the top structure can delay the spread of flames, protecting the lower spaces and ensuring the safety of evacuation. The high-temperature performance of calcium silicate fire boards not only meets the requirements of commercial and industrial buildings but also complies with strict fire safety regulations, providing a reliable fire barrier for buildings.
2. Low Heat Conductivity and Insulation Performance
The top protection not only needs to be fire-resistant and heat-insulating. Calcium silicate boards have the characteristic of low heat conductivity, which can effectively reduce the downward transfer of heat. This insulation effect not only protects the lower structure but also extends the time for personnel evacuation and emergency response. At the same time, the low heat conduction also plays an auxiliary role in the management of the internal temperature of the building, helping to maintain a constant indoor temperature and improving energy efficiency. It is particularly suitable for industrial and commercial buildings with high temperatures or long-term use.
3. Lightweighting and Ease of Processing
Top construction usually involves working at heights. The weight and processing difficulty of the materials directly affect the construction efficiency and safety. The lightweight design of New Element calcium silicate boards makes the transportation and installation safer and more convenient. At the same time, the boards are easy to cut, allowing for quick on-site adjustments of dimensions to fit complex spatial layouts. This not only shortens the construction period but also reduces labor costs and construction risks, improving the overall efficiency of the project.
4. Durability and Insect Resistance
The ceiling area is challenging to maintain, making the long-term performance of materials particularly crucial. Calcium silicate boards are wear-resistant, impact-resistant, and offer protection against woodworm and insects. Compared to traditional materials, they resist degradation and damage during long-term use, ensuring sustained ceiling protection.
5. Dimensional Stability
During the construction and usage process, the form stability of the materials directly affects the protective effect. The calcium silicate boards of New Element are manufactured using advanced techniques. Even in high humidity or temperature fluctuation environments, they can maintain dimensions without cracking, warping or shrinking.

Thickness Options for Ceiling Protection
The ceiling protection design needs to select different thicknesses of materials based on the building type, functional areas and fire resistance requirements. New Element calcium silicate boards offer a variety of thickness options.
Different thicknesses correspond to different fire resistance times and protection levels:
• Thin sheets (9-12mm): Suitable for ordinary commercial office spaces or residential projects, they can provide basic fire protection while reducing load.
• Medium-thickness sheets (15mm): Suitable for high-rise buildings, shopping centers or public facilities, it provides medium fire resistance time and structural stability for ceiling protection.
• Thick plates (24-27.5mm): Suitable for high-risk or industrial environments, such as factories, warehouses, tunnel and high-temperature operation areas. It can significantly extend the fire resistance time and enhance the top load-bearing and insulation capabilities.
Conclusion
Top protection is a crucial part of the building fire prevention system, directly affecting the evacuation of people and the safety of property during a fire. The New Element calcium silicate boards, with their multiple advantages such as high temperature resistance, low thermal conductivity, and durability stability, provide reliable and long-term protection for the ceiling. Whether it is a commercial office building, high-rise residential building, or industrial and public building, using calcium silicate fire boards can significantly improve the top safety and fire resistance level.
