Fire-resistant barriers used in construction thus far include: rock wool, foamed ceramics, foamed cement, foam concrete, and other A-grade fireproof materials. The exterior wall thermal insulation system of the rock wool fireproof isolation strip, commonly known as the "rock wool board," primarily employs hydrophobic rock wool boards manufactured via the pendulum method as the insulation layer material. These boards are secured using a combination of bonding and nail fixation techniques. This system forms a class A non-flammable building energy-saving insulation system, complete with a plastering layer, reinforced plastering fabric, and either a decorative mortar finish or coating. The system was developed by Baumit, Europe's premier insulation brand, and has received European Technical Certification (ETA) due to its over 30 years of experience in fire safety. The system structure generally consists of an adhesive layer, an insulation layer, a surface layer, a finish layer, and various accessories. The finish layer should consist of lightweight functional coatings such as veneer mortar, decorative mortar, or breathable water-based exterior wall paint. The exterior wall insulation system of the rock wool board offers advantages such as low thermal conductivity, good gas permeability, and high combustion performance levels. It can be applied to energy-saving and thermal insulation projects for new buildings, renovations of residential and public buildings, including external wall insulation, non-transparent curtain wall insulation, and fire isolation barriers for EPS external insulation systems.
In recent years, numerous building insulation fires have occurred, prompting various sectors to reconsider insulation and fireproof materials. The fireproof performance of insulation materials has garnered unprecedented attention from all industries. However, many insulation materials produce droplets and toxic fumes during combustion, and the environmental risks associated with the release of chlorofluorocarbons, hydrofluorocarbons, and freons are also concerning. In response, the Ministry of Housing and Urban-Rural Development and the Ministry of Public Security jointly issued the "Interim Provisions on Fire Protection Design, Construction, and Use of Civil Building Exterior Insulation Systems and External Wall Decorations" on September 25, 2009. A system with superior fire performance and excellent thermal insulation properties during the thermal insulation design process can capture the market.

Edit this paragraph exterior wall insulation multi-inorganic foam fire barrier with external wall insulation multi-inorganic foam fire barrier, it has several advantages: exterior wall fire barrier
1. High-resistance multi-inorganic foaming material belongs to Class A1 fireproofing material, has good fire resistance, and has a refractoriness of more than 1000 °C, which fully meets the fire resistance requirements of fireproof insulation belt.
2. High heat preservation Because the closed cell ratio of the multi-component inorganic foam material is >95%, the high closed cell ratio reduces the convective heat transfer, which is a prerequisite for high heat insulation. Therefore, the thermal conductivity of the Zhucheng fire barrier can reach 0.045W/m·k, which is basically equivalent to the thermal conductivity of the polystyrene board, which can meet the needs of building thermal insulation.
3. The strength is relatively good, and it is not easy to be broken. The fireproof isolation belt has high pressure resistance, flexural strength and high strength index. It achieves relatively uniform low density and high strength. It is not easy to be broken by use and transportation, and meets fire integrity.
4, light weight and light weight is another advantage of Zhucheng fire isolation zone. When the density is 100-300kg/m3, the requirements of the fire barrier can be achieved. At the same time, the cost can be greatly reduced.
5, non-toxic and harmless external wall insulation Multi-inorganic foam fireproof insulation belt raw materials will not burn at high temperature and does not release toxic gases, is a safe and environmentally friendly building materials.
6, long life wall insulation multi-inorganic foam fire barrier has a service life of more than 50 years, and the life of the building can keep pace.
7. Good water resistance Since the multi-component inorganic foam material is a silicate material, the water resistance is very superior.
8. The interface is good. Because the material is porous and homogeneous with mortar and wall surface, the interface is very good. During the construction process, unlike the organic or cotton insulation materials, it needs to be anchored and directly pasted.
9. Energy-saving and safe production The installation process does not emit harmful gases and wastes, nor does it have floating objects like inorganic cotton, which pollute the environment.
