The stone insulation composite board resembles natural stone, but its core is made of a special patented foam material that provides advanced features such as fire resistance and thermal insulation. This composite panel consists of three key layers: the outer stone surface, an insulating layer, and a fireproof backing. It offers numerous benefits, including being lightweight, fire-resistant, energy-efficient, durable, easy to install, cost-effective, and environmentally friendly. It significantly reduces the overall weight of buildings, making it ideal for both new constructions and renovations. Compared to traditional marble panels, this product offers three main advantages: energy efficiency, enhanced fire safety, and lower costs. While widely used in many foreign countries, it's still relatively new in China and mainly found in northern regions with colder climates. In addition to its fire protection capabilities, it can reduce heat loss by up to 65%, making it highly efficient. Moreover, it’s more affordable—about 50% cheaper than equivalent natural stone products. The stone insulation composite decorative board has several notable advantages: 1. Excellent thermal insulation performance, leading to high energy efficiency and significant savings. 2. Cost-effective solution, with installation costs lower than traditional stone facades. 3. Streamlined construction process—only three steps are needed compared to the 13 steps required for traditional methods. This not only shortens the project timeline but also minimizes cross-contamination, reduces risks, and ensures minimal disruption during building renovations. 4. Lightweight design improves structural safety and reduces load on the building framework. 5. Mass-produced in a controlled environment, ensuring consistent quality and eco-friendly production. 6. Easy to install, modify, and replace. Its modular design allows for standard-sized panels tailored to the building’s façade, making installation quick and efficient. The system is robust, and maintenance or replacement is straightforward and hassle-free.
