Introducing the Phenolic A-Class Fireproof and Insulating Ultra-Thin Granite Veneer Product:
The phenolic insulation board is a modern, non-combustible, and low-smoke material designed for fire protection and thermal insulation. It is a rigid, closed-cell foam made from phenolic resin combined with foaming agents and other additives. This material offers a stable chemical structure, resistance to corrosion and aging, and strong performance against organic solvents, strong acids, and weak alkalis.
One of its key features is that it does not melt or soften at high temperatures. It produces minimal smoke, resists flame spread, and prevents flame penetration. Its fire-resistant properties are exceptional, making it an ideal choice for fire safety. Additionally, it provides excellent thermal insulation, helping to reduce energy consumption. When exposed to high heat, the gas released is non-toxic, odorless, and environmentally friendly, meeting national green building standards.
The "Bangti" brand ultra-thin granite veneer is a new type of external wall insulation and decorative composite board developed by Shanghai Bangti Company. It uses phenolic foam as the core insulation material, reinforced with high-quality alkali-resistant fiberglass cloth, and covered with a special inorganic polymer mortar. This combination ensures compliance with the national A-class fire protection standard.
Inside the panel, a unique box-type reinforcing structure connects the insulation board's surface with the outer decorative stone, creating a unified system that integrates seamlessly with the building. The company also utilizes a special aluminum alloy hanger system to attach the composite panels to the wall. This innovative wet and dry hanging installation method enhances the safety and stability of high-rise buildings.
The exterior of the insulation board can be easily painted or adorned with various decorative finishes, offering great flexibility in design. The ultra-thin granite and marble stones produced by the "Bangti" ultra-thin stone cutting machine (Patent No. 6) are directly applied to the panel. These stones can be cut as thin as 3mm, significantly reducing the weight of the panel and the load on the building. This helps protect the structural integrity and extends the building’s lifespan. Compared to traditional stone cladding methods, this product offers lower costs, improved safety, aesthetic appeal, and faster installation. It also solves the long-standing issue of poor insulation in conventional decoration systems.
