With the rapid development of China's construction industry, the selection of exterior wall materials has become increasingly crucial. The exterior wall is not only the "coat" of a building, but also an important barrier to ensure building safety, energy efficiency, and aesthetics. Among numerous exterior wall materials, high-density calcium silicate board for exterior wall cladding has become the preferred choice for more and more construction projects due to its excellent performance. As a Rosewool Insulation Refractory Co.,Ltd that has been deeply involved in the field of insulation and refractory materials for many years, we have a deep understanding of the domestic construction market demand and are committed to providing high-quality high-density calcium silicate boards for external wall cladding to our customers, helping Chinese buildings achieve multiple goals of safety, energy conservation, and aesthetics. ​
There are generally two common types of high-density calcium silicate boards: glass fiber calcium silicate board (common type) and carbon fiber calcium silicate board (high temperature type), both of which have high compressive strength and a density above 800, but the specific The density can be customized according to customer requirements. N-14 is a glass fiber high-density calcium silicate board, and N-17 is a carbon fiber high-density calcium silicate board. The glass fiber high-density calcium silicate board is the common type in the high-density calcium silicate board, and the carbon fiber is the high-temperature type, which has better thermal shock resistance.
  • Calcium silicate board with a density of 300 is used in the electrolytic aluminum industry;
  • Ordinary calcium silicate board with a density of 220, used in cement plants;
  • Low-temperature microporous calcium silicate board and calcium silicate shell with a density of 220 and 650 degrees are used for heat pipes, oil pipes, and steam pipes.


Adapting to the needs of Chinese architecture, with outstanding performance advantages

China has a vast territory with significant differences in climate conditions across different regions, ranging from high temperatures and humidity in the south to severe cold and dryness in the north, which places extremely high demands on the performance of exterior wall cladding materials. The high-density calcium silicate board covering the exterior wall exhibits strong adaptability in dealing with these complex climatic conditions. ​

Firstly, it has excellent weather resistance. After special processing, the board can withstand long-term wind, sun, rain, and freezing. Even in extreme weather conditions, it is not prone to cracking, deformation, fading, and other problems, effectively extending the service life of building exterior walls. Secondly, its fire resistance is particularly outstanding. Against the backdrop of increasingly strict building fire prevention standards in China, the non combustible properties of high-density calcium silicate board covering the exterior walls can effectively prevent the spread of fire in the event of a fire, providing strong protection for the evacuation of personnel and property safety in buildings, fully meeting the requirements of China's building fire prevention regulations. ​

In addition, the board also has excellent thermal insulation performance. In the current energy shortage, building energy conservation has become an important direction for industry development. The high-density calcium silicate board covering the exterior wall can effectively block the transfer of outdoor heat or cold air, reduce energy exchange between indoor and outdoor buildings, lower the energy consumption of building air conditioning and heating systems, and help achieve the "dual carbon" goal, which is highly compatible with China's green building development concept. ​
                                         
Diversified application scenarios to meet different building needs

In the Chinese construction market, whether it is civil or commercial buildings, whether it is new construction projects or old building renovation projects, high-density calcium silicate boards covering the exterior walls can play an important role in meeting the needs of different scenarios. ​

In the field of civil architecture, residential communities, villas and other projects have high requirements for the aesthetics and living comfort of building exterior walls. The exterior wall is covered with high-density calcium silicate board, which has a smooth and flat surface. Various decorative treatments can be carried out according to design requirements, such as painting and pasting tiles, to create a rich and diverse architectural appearance and improve the overall quality of residential communities. Meanwhile, its excellent thermal insulation performance can create a comfortable indoor living environment for residents, reduce indoor temperature fluctuations, and improve the living experience. ​

In the field of commercial buildings, projects such as shopping malls, office buildings, and hotels have higher standards for the safety, durability, and aesthetics of building exterior walls. The high-strength characteristics of high-density calcium silicate board covering the exterior walls can withstand significant external impacts and are not easily damaged, ensuring the long-term stability of commercial building exterior walls. Its excellent fire resistance and weather resistance can also meet the characteristics of dense pedestrian flow and long service life in commercial buildings, providing a safe and reliable environment for businesses and consumers. ​

In the renovation project of old buildings, the high-density calcium silicate board covering the exterior walls has demonstrated unique advantages. It is lightweight, easy to construct, and does not require large-scale renovation of the original structure of the building. It can quickly improve the insulation, fire resistance, and aesthetic performance of the exterior walls of old buildings, effectively improve the living conditions of residents in old buildings, and reduce renovation costs and construction cycles, which meets the development needs of China's old renovation policies. ​
