What is Calcium Silicate Insulation Board
Calcium Silicate Insulation Board is a high-performance composite material made from quartz sand, cement, and cellulose fibers. It is widely used for ceilings, interior wall partitions, and exterior wall cladding panels.
Calcium silicate insulation board integrated exterior wall insulation and decoration panel is a new type of exterior wall building material that integrates three major functions: thermal insulation, decorative aesthetics, and durable protection. It adopts a factory prefabrication integrated production mode. The core structure consists of three composite parts: a surface decorative layer, a middle calcium silicate substrate, and an inner insulation layer. The surface decorative layer can be customized with various textures and colors such as wood grain, brick, and stone to suit different architectural styles.
The middle calcium silicate substrate, made primarily of silicon and calcium, is formed under high pressure and cured at high temperatures, possessing high strength and high stability. The inner insulation layer primarily uses modified thermosetting composite polystyrene insulation board, rock wool strips, unglazed foamed ceramics, foam glass, inorganic lightweight aggregate insulation composite board, polyurethane, and other high-efficiency insulation materials. These can be flexibly combined according to building energy-saving requirements, ultimately forming a performance-synergistic and easy-to-install integrated exterior wall solution.
The standard size is 1220 × 2440 mm, with thicknesses ranging from 30 mm to 100 mm, adjustable according to different climate conditions and insulation requirements. The board's density ranges from ≥1.2 to 1.4 g/cm³, and it is available in low-, medium-, and high-density options.

Performance Advantages: Balancing Insulation and Durability, Adaptable to Diverse Climates
1. High-Efficiency Insulation, Energy Saving and Consumption Reduction: The inner insulation layer effectively blocks heat transfer between indoors and outdoors, reducing the intrusion of high temperatures in summer and locking in indoor warmth in winter. This can reduce building energy consumption by 30%-50%, meeting national green building standards and saving owners long-term air conditioning and heating costs. It is especially suitable for rainy, humid southern regions with large temperature differences, avoiding the condensation and mold problems caused by insufficient insulation in traditional exterior walls.
2. Superior Weather Resistance, Long-Lasting Durability: The silicon-calcium substrate itself has high hardness, strong impact resistance, and excellent acid and alkali resistance and UV resistance. Combined with a waterproof and moisture-proof composite process, it can easily withstand the effects of typhoons, plum rains, and high-temperature exposure, effectively preventing exterior wall cracking, water seepage, and fading. Its service life can reach over 20 years, far exceeding the maintenance cycle of traditional coatings (5-8 years) and ordinary stone (10-15 years), reducing later renovation costs.
Practical Advantages: Green and Environmentally Friendly + Convenient Installation, Cost Reduction and Efficiency Improvement
1. Green, Safe, Healthy, and Livable: The silicon-calcium substrate uses natural inorganic materials as raw materials, with no formaldehyde or odor release during the production process. The surface decorative layer uses environmentally friendly coatings, meeting the national E0 environmental standard, avoiding pollution from building materials at the source. It is especially suitable for cultural and tourism towns, high-end residences, and other scenarios with high requirements for living health, aligning with the architectural concept of "ecological livability."
2. Factory Prefabrication and Rapid Installation: The product is manufactured as a single unit in the factory, eliminating the need for on-site cutting and painting. Installation can be completed simply through dry hanging or bonding processes, increasing installation efficiency by more than 50% compared to traditional exterior wall processes, significantly shortening the construction period. It also reduces on-site wet work, lowering construction dust and waste, meeting the requirements of modern "green construction," and is especially suitable for projects with tight schedules or high requirements for the on-site environment.
Adaptability Advantages: Versatile Style, Enhancing Architectural Aesthetics
1. Customizable Textures, Harmonious Styles: The surface decorative layer can precisely replicate the textures of various materials such as wood grain, blue bricks, stone, and metal, with high and uniform color saturation, adapting to various architectural styles including Jiangnan water towns, Neo-Chinese style, modern minimalism, and cultural tourism retro styles. For example, in cultural tourism projects such as the Shaoxing Sunac Yellow Wine Town, it can perfectly restore the warm texture of traditional Jiangnan architecture, avoiding the incongruity between modern materials and ancient architectural styles, allowing the architecture to naturally blend with the regional cultural atmosphere.
2. Durable Aesthetics, Everlasting Beauty: Compared to the problems of traditional paints fading easily and ordinary stone efflorescence, the decorative layer of the calcium silicate board exterior wall insulation and decoration integrated panel undergoes special weather-resistant treatment, maintaining a clean and beautiful appearance even after long-term use. It requires no frequent maintenance or renovation, maintaining the long-term aesthetics of the community or project while enhancing property value, making it especially suitable for developers who value brand image and long-term quality.
