Guangzhou ALCC Panel - Foshan Zhonglian Optimal Technology Co., Ltd. is a specialized manufacturer of ALCC panels.
In recent years, many buildings have begun to utilize ALC exterior panels as construction materials. It is crucial to understand the various performance features and construction considerations of the panels, continuously improving and leveraging their advantages.
Civilian buildings offer warmth in winter and coolness in summer, thus efforts will be intensified on the exterior and interior walls. Considering the temperature difference between day and night, when the outdoor temperature is lower than the indoor temperature, the shrinkage of the exterior wall exceeds that of the internal insulation system. Conversely, when the outdoor temperature is higher than the indoor temperature, the expansion rate of the exterior wall surpasses that of the internal insulation system. Under the repeated action of this deformation stress, not only is the exterior wall prone to damage from temperature differences, but also the internal insulation system may experience hollowing and cracking. This is a test for the wall panels.
During the construction and installation process, the construction should be carried out in a fixed sequence to ensure the stability of the wall panels. Of course, the construction methods vary depending on different situations, so it is necessary to formulate plans accordingly.
alc exterior panels offer numerous excellent properties. They weigh less than bricks and other wall panels. This reduces the self-weight of buildings, decreases the amount of structural materials used, lowers the cost of foundations, and thus saves a significant amount of resources throughout the construction cost. They also have high thermal conductivity, making them suitable for insulation purposes and can serve as fire barriers. However, the fire resistance of the panels is limited.
Excellent thermal performance and long service life. Also widely used as a fire barrier in special occasions. It does not produce harmful pollution during production and transportation. A green building material product.
Guangzhou ALc Board - Foshan Zhonglian Optimal Technology Co., Ltd. is a specialized manufacturer of ALc boards.
Insulation properties of the Alc board
ALC panels not only offer excellent thermal insulation properties [λ=0.13 (W/m·K)], but also possess good heat retention characteristics [heat storage coefficient s=2.75 W/(m·K)]. With appropriate thickness, they are suitable for both cold regions with high thermal insulation requirements and hot-summer-cold-winter or hot-summer-warm-winter regions with high thermal insulation demands, meeting energy-saving standards.
Sound Insulation: This material is a porous one composed of a large number of uniformly distributed and non-connected micro-pores, offering excellent sound insulation properties. The average sound insulation rating of a 100mm thick board is 40.8db, while that of a 150mm thick board is 45.8db.
Fire Resistance: ALC board is an incombustible inorganic material with excellent fire resistance. Primarily used as wall panels, the fire resistance limit of 100mm thick boards is 3.23 hours; for 150mm thick steel plates, it is >4H; for 50mm thick steel plates protecting steel beams, the fire resistance limit is >3 hours; for 50mm thick steel plates protecting steel columns, the fire resistance limit is >4H; all exceeding fire resistance standards.
Buildability: The panel production is industrialized and standardized, with installation, sawing, planing, and drilling processes industrialized as well. Dry construction method, with quick speed.
Compatibility: The board features a robust application support system, equipped with connectors, pointing agents, repair powders, and interface agents.
Installation easy, cost-effective: This material requires no plastering, reducing costs by 20-25 yuan per square meter; putty and paint can be used directly.
Excellent surface quality, free of cracks: The material dries during application, with the board surface free from hollowing and cracks.
ALC boards, a new type of material with superior performance, are primarily made from three materials: fly ash, lime, and cement. Also known as autoclaved aerated concrete, this material is crafted through a process requiring numerous layers of technology, resulting in a versatile product that can be used as both walling material and roof panels.
ALC panels serve as both wall and roof materials, representing a new type of building material with superior performance. First introduced in Europe, ALC has a production and application history of over 40 years in regions such as Japan and Europe. Currently, domestic manufacturers primarily import production technology and equipment from Japan and Germany. Properties of ALC panels:
Acoustic Insulation: The material is a porous one composed of a large number of uniformly distributed, non-interconnected tiny air pores, offering excellent soundproofing properties.
Fire Resistance: ALC panels are a non-combustible inorganic material with excellent fire resistance properties. As a wallboard, a 100mm thick panel has a fire resistance limit of 3.23 hours.
Durability: ALC is an inorganic silicate material that does not age and boasts excellent durability.
Waterproofing: Offers superior waterproofing properties, five times better than standard bricks.
ALC Panels' Practical Advantages: 1. For instance, ALC panels are lightweight yet strong with low density. 2. The internal structure of ALC panels is stable, resistant to weathering, and has excellent resistance to acids and alkalis. They are not prone to aging and have a long service life. 3. They provide excellent thermal insulation, three times better than clay and ten times better than concrete, with excellent fire resistance. 4. ALC materials are environmentally friendly, free of formaldehyde and other harmful substances, suitable for residential building interiors, etc. 5. They also offer a short construction period.
