In the field of construction, the service life of external wall insulation material is one of the key indicators to measure its performance. As a new type of high-performance insulation material, ceramic insulation board for exterior wall is gradually becoming the ideal choice for building exterior wall insulation by virtue of its excellent durability. Why does it have a long service life? What’s the secret code behind this? Next, let’s find out.
First, high-quality raw materials to lay a solid foundation
The external wall ceramic insulation board is usually made of clay tailings, ceramic fragments, river silt and other main raw materials, which have good chemical stability and physical properties. After high temperature calcination, the harmful substances in the raw material are fully removed, so that it has a higher purity and stability. Compared with some traditional insulation materials, such as polystyrene (EPS), extruded polystyrene (XPS) and other plastic insulation materials, the raw material characteristics of external wall ceramic insulation board determine its inherent advantages in weather resistance and anti-aging. In the process of long-term use, plastic insulation materials are susceptible to ultraviolet light, temperature changes and other factors, resulting in aging and embrittlement, thereby shortening the service life. The inorganic raw materials used in the external wall ceramic insulation board can effectively resist the erosion of these external factors, providing a strong guarantee for its ultra-long life.

Second, advanced technology to create a stable structure
High temperature firing process: external wall ceramic insulation board in the production process, need to undergo high temperature roasting above 1200℃. In such a high temperature environment, the raw materials undergo a series of physical and chemical reactions to form a stable closed-cell ceramic structure. This closed-cell structure makes the pores inside the plate independent of each other, greatly reducing air convection and heat transfer, not only improving the thermal insulation performance, but also enhancing the strength and stability of the plate. Compared with some thermal insulation materials using low-temperature processing technology, high-temperature fired external wall ceramic thermal insulation board can better maintain its structural integrity during long-term use, and is not easy to deformation, cracking and other problems.
Precision production process: from the screening and matching of raw materials to mixing, molding, firing and subsequent processing, each link follows strict production standards and technological processes. Advanced automated production equipment and precise quality control system ensure that the quality of each external wall ceramic insulation board is uniform. For example, in the raw material mixing process, through high-precision metering equipment and mixing devices, to ensure that various raw materials can be fully and evenly mixed to avoid differences in sheet performance due to uneven composition. In the forming process, advanced mold and pressing technology is used to strictly control the dimensional accuracy and surface flatness of the plate, laying a good foundation for subsequent installation and use.
Third, excellent performance to help long-term durability
Strong weather resistance: whether it is the scorching summer, or the cold winter, or the bad weather with wind and rain, the external wall ceramic insulation board can cope calmly. Its stable chemical properties make it not fade, aging and other phenomena under long-term ultraviolet irradiation; Under large temperature changes, it can also maintain good dimensional stability, and will not cause cracks or deformation due to thermal expansion and cold contraction. In some high altitude areas, the temperature difference between day and night is very large, ordinary insulation materials are often difficult to withstand this drastic temperature change, and the external wall ceramic insulation board can rely on its excellent weather resistance, long-term stability to play the role of insulation.
Excellent anti-aging performance: As an inorganic ceramic material, the aging rate of external wall ceramic insulation board is extremely slow. Compared with organic insulation materials, it will not gradually decompose and deteriorate as organic materials do over time. In actual use, even after decades of wind and rain, the performance indicators of the external wall ceramic insulation board can still be maintained at a high level, and truly achieve the same life with the building. This feature eliminates the need for frequent replacement of insulation panels throughout the building’s life cycle, greatly reducing maintenance costs and construction difficulties.
Good waterproof and moisture-proof performance: the water absorption rate of the external wall ceramic insulation board is very low, which can effectively prevent the intrusion of water. This not only avoids the decrease of thermal insulation performance caused by moisture penetration, but also prevents the plate from mildew and rot due to long-term moisture. In the humid and rainy areas in the south, many buildings have poor waterproof and moisture-proof performance of thermal insulation materials, resulting in mildew and falling off of the walls, which seriously affect the beauty and service life of buildings. The excellent waterproof and moisture resistance of the external wall ceramic insulation board provides a reliable thermal insulation solution for the buildings in these areas, ensuring that the buildings can still maintain good condition in a humid environment.
High strength and stability: the external wall ceramic insulation board has a high compressive strength and tensile strength, and can withstand a certain external impact. In daily use, even if it is slightly bumped or scratched, it is not easy to damage. At the same time, it has good compatibility with cement mortar, concrete and other wall materials, and the expansion coefficient is similar, and it can cooperate with the wall in the process of thermal expansion and cold contraction, and there will be no empty drum, falling off and other phenomena. This combination of high strength and stability makes the external wall ceramic insulation board always firmly attached to the wall surface during long-term use, providing continuous and stable thermal insulation protection for the building.
Fourth, the correct installation and maintenance to extend the service life
Professional installation: The correct installation method is an important prerequisite for the long life of the external wall ceramic insulation board. During the installation, the construction personnel must strictly follow the product installation instructions and related construction specifications. For example, in the pasting process of the plate, it is necessary to ensure that the binder is evenly applied and firmly pasted to avoid virtual adhesion and empty drums. At the same time, there are also strict requirements for the installation location and number of anchor parts to ensure that it can effectively enhance the connection strength between the plate and the wall. The professional construction team can reasonably plan the installation scheme according to the actual situation of the building to ensure that each external wall ceramic insulation board can be installed in place, so as to give full play to its performance advantages and extend its service life.
Regular maintenance: Although the external wall ceramic insulation board has good durability, regular maintenance is still indispensable. Regularly check the surface of the external wall ceramic insulation board for damage, cracks, etc., if found, it should be repaired in time. At the same time, it is necessary to keep the surface of the plate clean, avoid dust, dirt and other accumulation, affecting its beauty and thermal insulation performance. In some areas with more serious industrial pollution, it is also necessary to regularly clean the ceramic insulation board on the external wall to prevent the erosion of pollutants on the board. In addition, for the environmental changes around the building, such as tree growth, construction activities and other factors that may affect the external wall, it is also necessary to pay close attention to and take appropriate protective measures in time to ensure that the service life of the external wall ceramic insulation board is not affected.
External wall ceramic insulation board with its high-quality raw materials, advanced technology, excellent performance and correct installation and maintenance, unlock the password of ultra-long life. Under the general trend of building energy conservation and green building development, external wall ceramic insulation board with its excellent durability, provides long-term and stable insulation protection for buildings, and becomes a bright star in the field of building external wall insulation, which will play a more important role in the future construction market.
