What are the advantages and disadvantages of calcium silicate board

Release Time: 2025-08-20

In the field of modern architecture and industrial insulation and fire resistance, calcium silicate board, as a new type of energy-saving and environmentally friendly material, is gaining widespread attention due to its unique properties. It is mainly made of siliceous and calcareous materials through molding, steam curing and other processes, and plays an important role in wall partitions, ceiling decoration, equipment insulation and other scenarios. However, every material has its duality, and calcium silicate board is no exception. Today, we will delve into the advantages and disadvantages of calcium silicate board and recommend a reliable purchasing option for you - Rosewool Insulation Refractory Co.,Ltd.

The advantages of calcium silicate board are very prominent, making it stand out among many building materials. Excellent fire resistance is one of its core advantages. Calcium silicate board is a non combustible material that does not burn or release toxic gases in high temperature environments, effectively delaying the spread of fire. When a building fire occurs, it can buy valuable time for personnel evacuation and firefighting rescue, making it an ideal fireproof building material for high-rise buildings, large shopping malls, industrial plants and other places. For example, in the ceiling decoration of large shopping centers, the use of calcium silicate board can significantly improve the fire safety level of the building.

Excellent thermal insulation performance is also a major highlight of calcium silicate board. Its internal structure is dense and contains a large number of closed pores, which can effectively prevent heat transfer. It can play a good energy-saving role in both building wall insulation and industrial equipment insulation. In the insulation engineering of building exterior walls in cold regions, the use of calcium silicate board can reduce indoor heat loss and lower heating energy consumption; In the insulation of the outer wall of industrial kilns, it can effectively prevent high temperatures from spreading to the outside and ensure the safety of the surrounding environment of the equipment.

Calcium silicate board: With a high-temperature resistance of 1000 degrees, it is used as an inner lining insulation material layer. It has good compressive strength, low thermal conductivity, and can be cut and processed in various complex environments during construction.

In addition, calcium silicate board also has the characteristics of high strength and good durability. It has high flexural and compressive strength, is not easily deformed or cracked, and can withstand certain external impacts. At the same time, it has good weather resistance, is not afraid of moisture or corrosion, and is not easily damaged when used in damp environments such as bathrooms and kitchens. Its service life can reach several decades. Moreover, calcium silicate board is easy to construct and can be sawed, nailed, and planed. It can be processed into various shapes according to actual needs, greatly improving construction efficiency.

Of course, calcium silicate board also has some shortcomings. One of its obvious drawbacks is its high weight. Compared to lightweight building materials such as gypsum board, calcium silicate board has a higher density and a heavier weight per unit area, which increases the load on the building structure. When used in situations where there are strict restrictions on building loads, caution should be exercised, and reinforcement treatment may be required for walls or ceiling keels.

The relatively high price is also one of the factors affecting its popularity. Due to the complex production process and high raw material costs, the market price of calcium silicate board is higher than that of ordinary building materials such as gypsum board and cement board, which to some extent increases the initial investment cost of the project. In addition, calcium silicate board is prone to generating dust during cutting and processing, and construction personnel need to take protective measures, otherwise it may have an impact on health.

Although calcium silicate board has some drawbacks, these issues can be optimized to some extent by selecting products from high-quality manufacturers. Rosewool Insulation Refractory Co.,Ltd., as a well-known enterprise in the industry, has comprehensively upgraded the quality of its calcium silicate board production. With over 40 years of production experience and strong technical strength, the company continuously improves the production process of calcium silicate board.
