In modern urban life, noise pollution has become a major problem affecting people’s quality of life. Whether it is the heavy traffic noise, or the noise of the surrounding construction, people are eager to have a peaceful living and working environment. External wall ceramic insulation board, as a leader in the field of building external wall materials, not only in the thermal insulation performance of excellence, its excellent sound insulation and noise reduction performance, more people bring quiet space enjoyment, become the right assistant to create a comfortable environment.
First, a unique structure to build sound barriers
Closed cell ceramic structure: In the production process of external wall ceramic insulation board, after high temperature roasting above 1200℃, a stable closed cell ceramic structure is formed. These closed holes are independent of each other, like a tiny soundproof chamber, when the sound wave is passed into the inside of the plate, it will constantly reflect and refract between these closed holes. Each reflection consumes a portion of the sound energy, causing the sound wave to gradually decay as it travels. Unlike some insulation materials with open hole structure, the closed hole structure of the external wall ceramic insulation board effectively prevents the direct penetration of sound waves and greatly enhances the sound insulation effect. For example, in residential buildings facing the street, after the installation of external wall ceramic insulation panels, the indoor isolation effect of traffic noise is significantly improved, and residents can obviously feel the weakening of external noise.
Multi-layer composite structure: In addition to the sound insulation effect of the closed-cell ceramic structure itself, the external wall ceramic insulation board usually uses a multi-layer composite structure design. It generally includes ceramic insulation layer, reinforced fiber layer and protective surface layer. Ceramic insulation layer as the core part, undertake the main sound insulation and heat preservation functions; The reinforced fiber layer can enhance the strength and stability of the plate, and can also scatter and absorb the sound wave. The protective surface layer protects the internal structure from the erosion of the external environment and ensures the long-term stability of the board performance. This multi-layer composite structure works together to block the propagation of sound waves from different levels, further improving the overall sound insulation and noise reduction ability. In some places with high requirements for sound insulation, such as schools, hospitals and other buildings, the multi-layer composite structure of ceramic insulation board on the external wall can effectively isolate various noises from the outside world, and create a quiet learning and treatment environment for teachers and students and patients.
Second, sound absorption principle to reduce noise interference
Sound waves are converted into heat energy: The ceramic material inside the external wall ceramic insulation board has certain sound-absorbing characteristics. When the sound waves hit the surface of the plate, part of the sound waves will be reflected back, while the other part will enter the plate. Inside the plate, the sound waves interact with the pores, grain boundaries and other microstructure of the ceramic material, and the energy of the sound waves is gradually converted into heat energy and consumed due to friction and air viscosity resistance. This process of converting sound energy into heat energy effectively reduces the intensity of sound waves, thus reducing noise interference to the indoor environment. In some commercial buildings, such as shopping malls, office buildings, etc., the external wall ceramic insulation board can absorb part of the external noise, reduce the indoor noise level, and provide a more comfortable environment for customers and office staff.

Resonance absorption of specific frequency sound waves: The microstructure and material characteristics of the external wall ceramic insulation board enable it to resonate with some specific frequency sound waves to a certain extent. When these specific frequency sound waves act on the plate, the plate will produce resonance phenomenon, and the resonance process will absorb the energy of the sound waves. Through the reasonable design of the structure and material composition of the plate, the external wall ceramic insulation board can have a better absorption effect on the common noise frequencies, such as the middle and low frequency part of traffic noise and the high frequency part of the human voice. This absorption capacity for specific frequency sound waves makes the external wall ceramic insulation board can play an excellent sound insulation and noise reduction role in different noise environments, providing users with a full range of quiet protection.
Third, it has obvious advantages in comparison with traditional materials
Superior to ordinary brick walls: Although ordinary brick walls have a certain ability to sound insulation, they often seem powerless in the face of complex and diverse noises in modern cities. The sound insulation of brick walls mainly depends on their thickness and quality, however, increasing the thickness will not only take up more space, but also increase the cost of construction. In contrast, the external wall ceramic insulation board with its unique structure and material characteristics can achieve better sound insulation effect at a relatively thin thickness. For example, the same 200mm thickness of the wall, the use of external wall ceramic insulation board of the composite wall than the ordinary brick wall can increase the volume of 5-10 decibels, can more effectively block the outside noise into the room.
Better than organic insulation materials: some common organic insulation materials, such as polystyrene foam board, polyurethane foam board, etc., perform well in terms of insulation performance, but there are obvious shortcomings in sound insulation and noise reduction. These organic materials have a lighter texture, relatively loose internal structure, easy penetration of sound waves, and poor sound absorption. As an inorganic material, the external wall ceramic insulation board has a high density and stable structure, which can better reflect and absorb sound waves, and the sound insulation performance is far better than that of organic insulation materials. In practical applications, the indoor noise level of buildings using external ceramic insulation panels is significantly lower than that of buildings using organic insulation materials, creating a quieter living and working space for users.
Fourth, a wide range of practical application scenarios
Residential construction: In the residential field, the sound insulation and noise reduction performance of ceramic insulation panels on the external walls brings a peaceful living environment to residents. Whether it is a high-rise apartment in the city center or a single-family villa in the suburbs, after installing external wall ceramic insulation board, it can effectively isolate traffic noise, neighborhood noise and other interference. Residents can enjoy quiet rest time indoors, improve the quality of sleep, but also more focused on learning, work and other activities. For example, in some residential communities near the main road, residents reported that after installing ceramic insulation panels on the external walls, indoor noise was significantly reduced and living comfort was greatly improved.
School building: As a place for students to learn and grow, the school requires a quiet environment. The external wall ceramic insulation board can effectively isolate the traffic noise, construction noise and noise generated by off-campus activities around the campus, creating a good teaching and learning environment for teachers and students. In the classroom, the quiet atmosphere helps students to concentrate and improve learning efficiency; In places such as libraries that require absolute silence, the sound insulation effect of ceramic insulation panels on the external walls is crucial to ensure that students can read and study in a quiet environment.
Hospital architecture: A hospital is a place where patients are treated and rehabilitated, and a quiet environment is essential for patient recovery. The external wall ceramic insulation board can block various noises from the outside world, such as the ambulance siren, the noisy noise around the hospital, etc., to create a quiet and comfortable atmosphere for the ward, which is conducive to the rest and rehabilitation of patients. At the same time, in the hospital operating room, intensive care unit and other areas with high environmental requirements, the excellent sound insulation performance of the external wall ceramic insulation board can also ensure the smooth progress of medical work and avoid interference from external noise to medical operations.
Commercial buildings: In commercial buildings such as shopping malls and office buildings, ceramic insulation panels on external walls also play an important role in sound insulation and noise reduction. For shopping malls, quiet shopping environment can improve customers’ shopping experience, increase customers’ stay time and consumption intention; For office buildings, a quiet office environment helps to improve the work efficiency and work quality of employees. External wall ceramic insulation board can effectively reduce the impact of external noise on the interior of commercial buildings, providing a comfortable and quiet space for businesses and office personnel.
External wall ceramic insulation board with its unique structure, excellent sound absorption principle and significant advantages compared with traditional materials, in the field of sound insulation and noise reduction has shown a strong strength. Its wide range of application scenarios provide high-quality sound insulation solutions for different types of buildings, so that people can enjoy a comfortable and quiet space indoors. With the continuous improvement of the requirements of the construction industry for environmental protection, energy saving and comfort, the external wall ceramic insulation board will be more widely used in the future construction market, and play a greater role in creating a quiet and beautiful living environment.
