Analyze the prospects of fire insulation materials industry

In recent years, many cities have successively encountered fires of external thermal insulation materials, causing serious casualties and property losses. The construction of flammable and combustible external insulation materials has become a new type of fire hazard, and the resulting fires have shown multiple trends. Relevant state departments have given high priority and have issued relevant restrictive regulations in succession.

The State functional department intensified the second provision of the “Civil Building External Insulation System and Temporary Regulations for Fire Protection of Exterior Wall Decoration” issued in 2009. “Civil building exterior insulation materials use Class A materials for combustion performance”. This means that the external wall and external wall insulation systems will prohibit polyurethane and polystyrene products from being put on walls. This is a good news for Gent, because the external insulation industry will face another reshuffle, which means huge business opportunities.

Contents of Fire Protection Policy The Ministry of Public Security issued the "Notice on Further clarification of the Requirements concerning Fire Supervision and Management of External Thermal Insulation Materials for Civil Buildings" and clearly stated that the external insulation material for civil buildings shall be included in the scope of the fire engineering design audit, fire acceptance and record inspection for construction projects. The notice also stated that before the issuance of the new standard, the second provision of the "Temporary Regulations on Fire Protection for Civil Building Exterior Insulation System and Exterior Wall Decoration" shall be strictly implemented, and the exterior insulation material for civil buildings shall be Class A material. The main policy content is as follows:

(1) Incorporating civil building external insulation materials into civil engineering buildings with external insulation materials within the scope of fire engineering design review, fire inspection, and inspection and sampling inspection of construction projects. The material's combustion performance is included in the audit and acceptance content. The civil buildings with external insulation materials outside the scope of Article 13 and Article 14 of the Regulations for the Supervision and Administration of Fire Protection in Construction Projects (Ministry of Public Security Department Order No. 106) shall all be included in the scope of spot checks. Before the issuance of the new standard, the second provision of the “Provisional Regulations on Fire Protection for Exterior-insulated Civil Building Systems and Exterior Wall Decoration” of Civil Building (No. [2009] No. 46) shall be strictly enforced. The external insulation materials for civil buildings shall have Class A combustion performance. material.

(II) Strengthening the fire supervision and management of external thermal insulation materials for civil buildings From March 15, 2011 onwards, all projects accepted by the local governments for fire engineering design review and fire protection acceptance shall be strictly implemented. For projects under construction that have been approved for approval, such as the use of flammable combustible materials for exterior insulation of buildings, the relevant government departments shall be invited to supervise the construction unit to dismantle the flammable, combustible and heat-insulating materials; for those construction projects that have been approved but not yet commenced, If flammable or flammable materials are used for building exterior insulation, the construction unit shall be urged to change the design, select non-combustible materials, and reapply for review.

Analysis of fire insulation market It is understood that at present, there are few companies with fire performance reaching B1 level on the market of wall insulation, and there are only a few companies that have achieved A level, and most of them are Japan Mitsubishi, Germany's Aruk State and Germany. Fukui and other foreign giants, the price deterred most of the development companies. For example, the price of A2 aluminum sheet in Arukhan, Germany, is 500 yuan per square meter, which is 5 to 10 times higher than that of the domestic class B aluminum sheet. Although the price of A2 grade aluminum plates developed by domestic companies is 200 yuan/m2, the prices of the relatively B grade products are also 3 to 5 times higher. Moreover, these innovative products need to be reviewed and inspected by a number of inspection departments of the country. The time cost also makes it impossible for the development companies to abandon them. Increasing the rigid regulations for firebreaks also adds new costs. Each additional layer of firebreaks will cost tens to hundreds of dollars. In this regard, relevant experts in the industry pointed out that China's external thermal insulation companies should strengthen their research on fire protection basics, accelerate technological innovation in the wall insulation industry, develop higher fire protection levels as early as possible, and be able to form industrial scale, and the prices are easily accepted by the market. Save new resources and new technologies that can save resources and can be reused to respond to industry reshuffle. Class A Fireproof and Thermal Insulation Boards In terms of fireproof and thermal insulation applications, in general, the general specifications require insulation systems and thermal insulation materials to perform combustion performance and fire resistance limit tests (taking into account the smoke and toxicity during combustion), and are divided into several grades and grades. The scope of application of systems and materials is different. The polyphenylene board external insulation thin plastering system adopted for more than 85% of domestic projects is prohibited in more than 20 states. In the United Kingdom, buildings outside 18m are forbidden to use polystyrene thermal insulation systems, and in Germany, buildings above 22m are also prohibited from using polystyrene systems. Therefore, in the entire European and American countries, polyphenyl board insulation system has been rarely used.

From the point of view of the European insurance company, it is no longer necessary to insure buildings with polystyrene insulation systems. Although the country in the country in the JG149-2003 "Expansion polystyrene board thin plaster external insulation system", must use flame-retardant polystyrene insulation board; JG158-2004 "plastic powder polystyrene particles outside the wall insulation The system's fire reactivity (should not be ignited, and the thickness of the test piece does not change by more than 10% after the end of the test) is clearly defined. However, the selection of fire insulation barriers for different insulation systems and the selection of the insulation material on the side of the door behind the wall of the system are not adequate. Although at the end of 2009, the Provisional Regulations on Fire Protection for Civil Building Exterior Insulation Systems and Exterior Wall Decoration jointly issued by the Ministry of Construction and the Ministry of Public Security had further stipulated provisions, there were many non-compliances in the on-site projects. Post-release building fires are still commonplace. Therefore, on March 14, 2011, the Ministry of Public Security issued the "Circular on Further clarification of the Requirements for Fire Supervision and Management of External Thermal Insulation Materials for Civil Buildings", which stipulates that external wall insulation materials must be Class A non-combustible materials.
