What materials are commonly used for external wall insulation and internal wall insulation?

In recent years, with the comprehensive and compulsory promotion of building energy-saving exterior wall insulation materials in new residential and commercial buildings and even some old houses in China, the flammable problem of organic materials has also been exposed. Flammable external wall insulation materials frequently cause troubles in various places, and major fires that devour life and property follow. Take three famous fires in China as an example. The new building of Beijing CCTV under construction uses polystyrene board (EPS) as external wall insulation material. "1 1" caused by building decoration? In the "15" catastrophic fire, the building of Jiaozhou Road in Shanghai used polyurethane foam as thermal insulation material. Extruded polystyrene board is used as the external wall insulation material of Shenyang Dynasty Wanxin Building. The above three kinds of external wall thermal insulation materials are widely used at present, and their advantages are low one-time cost, convenient construction and good thermal insulation performance. However, they are made of organic materials, and they have the same fatal defect: strong flammability. Even if the flame retardant is added to the raw materials, it has a certain flame retardant effect, but these organic materials are still easy to catch fire, and once the temperature reaches a certain level, it is difficult to put it out, which leads to the rapid spread of the fire throughout the building. Even more deadly, organic thermal insulation materials will produce toxic gases when burned, and people will die if they inhale too much. The fire of Wanxin Mansion in Shenyang Dynasty not only proves once again that flammable external wall insulation materials are the "culprit" and contributed to the fire; It also warns people that organic external wall insulation materials are also easy to ignite, causing major fires in built-in buildings.

Established in 2008, Shijiazhuang Chengzhou Environmental Protection Materials Co., Ltd. is an enterprise specializing in the production and operation of A-class fireproof exterior wall insulation materials in Shijiazhuang. At present, the building area is 200,000 square meters and the building area is 3 million square meters. Our company mainly produces STP ultra-thin vacuum insulation board, self-adjusting phase change insulation mortar, dry powder mortar, bonding mortar and anti-crack mortar, which are mainly used in building decoration industry. Welcome people from all walks of life to call or write to consult our products!

After years of research, development, experiment and demonstration, Shijiazhuang Chengzhou Environmental Protection Materials Co., Ltd. launched a new STP ultra-thin thermal insulation and decoration system on 20 10. The system integrates thermal insulation and exterior wall decoration, and the thermal insulation effect is 3-5 times that of the products on the market at present. The technical system has won six national invention patents, leading internationally, and has been recognized and strongly recommended by national authoritative departments and relevant scientific research institutions. The technical system has been included in the national science and technology support plan (Eleventh Five-Year Development Plan) and the 20 10 science and technology project of the Ministry of Housing and Urban-Rural Development. The company is equipped with the international leading automated production line, forming a standardized and large-scale production capacity.
