External wall insulation systems are not only suitable for heating buildings in cold northern regions requiring winter thermal insulation but also apply to air-conditioned buildings in southern regions needing summer heat isolation. They are applicable to both new constructions and energy-efficient retrofits of existing buildings. These systems enhance the thermal insulation performance of walls while improving indoor thermal stability. By partially preventing moisture penetration (e.g., rainwater), they boost wall damp-proofing capabilities, effectively avoiding indoor condensation and mold growth, thereby creating a comfortable living environment.

Do you know this kind of fireproof material that is like cement board?
Several types of calcium silicate insulation materials



Calcium silicate board is a new type of inorganic building panel made primarily from siliceous materials, calcareous materials, and reinforcing fibers through a high-temperature, high-pressure process. Due to its excellent comprehensive performance, calcium silicate board finds wide application in various fields such as construction, industry, and shipbuilding.



The advantages of calcium silicate insulation materials:

1. Outstanding high-temperature resistance performance:

The usage temperature of ordinary products can reach up to 650°C, while some products with specially formulated treatments (such as hard calcium silicate type) can withstand a long-term temperature of up to 1000°C.

2. Class A Non-combustibility:

It will not catch fire in the presence of open flames or high temperatures, and can effectively prevent the spread of the fire.

3. High strength and excellent durability

The calcium silicate material has a dense structure and its mechanical strength is much higher than that of many other soft insulation materials.

4. Low thermal conductivity and excellent insulation efficiency

Within the range of 0.035 - 0.065 W/(m·K).




Silicate calcium insulation products are classified differently depending on their application scenarios. And performance requirements for calcium silicate board vary significantly across different scenarios. So, how should one choose the appropriate type?






We can categorize types based on application scenarios:


​​Building Interior Applications (e.g., Walls, Ceilings):​​ Priority should be given to ​​flatness and environmental friendliness​​. It is advisable to select ​​autoclaved high-pressure curing panels​​ with a thickness of ​​6mm-12mm​​. This type of board has a smooth surface, meeting the "ready-to-paint" standard, and has formaldehyde emissions ​​≤ 0.1 mg/m³​​.




​​Humid Environments (Bathrooms, Basements, Garages):​​ The core requirement is ​​moisture resistance and deformation resistance​​. Specifically choose ​​"Moisture-resistant Type Calcium Silicate Board"​​. This type has a ​​moisture content ≤ 8%​​, ​​water absorption expansion rate ≤ 2%​​, and has passed a waterproof test (no delamination after ​​24-hour immersion​​). During installation, joints ​​must be treated with sealant​​ to prevent moisture ingress.




​​Industrial Load-Bearing Scenarios (Cable Trench Covers, Equipment Protective Plates):​​ Requires ​​strength and durability​​. It is recommended to use high-strength boards with a ​​density of 1.2-1.5 g/cm³​​, possessing a ​​flexural strength ≥ 8 MPa​​ and a ​​compressive strength 15~20 MPa​​. If applied in ​​high-temperature environments​​ (e.g., boilers, flues), ensure the board has ​​high-temperature resistance​​, capable of ​​withstanding temperatures above 200°C​​ long-term without powdering.



Selecting calcium silicate board is ​​not simply about "buying a panel"​​ but rather a ​​systematic decision-making process based on market needs​​. Making a ​​scientific choice​​ not only ensures project quality but also reduces long-term maintenance costs.
