**Product Description:**
The "Bangti" brand A-grade fireproof and heat-insulating real stone lacquer veneer is a national patented product developed by Shanghai Bangti Company. It is an advanced solution for exterior wall insulation and decoration, combining high-performance insulation with elegant aesthetics. The composite panel features a unique box-type reinforced structure, with the outer shell made of inorganic polymer mortar, the middle layer composed of alkali-resistant fiberglass cloth, and the core insulation material being pure inorganic water-repellent glass wool. This glass wool has a water-repellency coefficient of up to 98%, a bulk density of 80 kg/m³, and a thermal conductivity as low as ≤0.032 W/(m·K), ensuring excellent insulation performance and durability.
The innovative in-box reinforcement design connects the wall surface and the decorative layer, while a special adhesive integrates the board with the building structure, forming a unified whole. The outer layer is finished with high-quality real stone paint, offering a premium decorative finish that overcomes common issues like cracking, blistering, and peeling found in traditional exterior coatings.
Test results have shown that the "Bangti" system has significantly higher tensile and shear strength compared to conventional insulation systems—often ten to hundreds of times stronger. Its lifespan can match that of the building itself. The production process eliminates common problems such as separation between the insulation layer and the wall, and surface alkali issues. Additionally, the lightweight and easy-to-install design makes it ideal for both new construction and renovation projects.
The product is widely used in exterior wall insulation, retrofitting of old buildings, and manufacturing fireproof and heat-insulating composite panels. It offers quick installation, improving overall construction efficiency.
