New external wall insulation materials become more and more popular

The country's requirements for the safety, environmental protection and energy conservation of building materials will become increasingly strict, and the traditional building materials will gradually fade, while new building materials will gain new opportunities for development. Increasingly strict building materials, the traditional organic thermal insulation building materials will be dying, and new building materials in demand will reach millions of tons, at least for now in China several times of production, production enterprises will get the new development opportunity, the listed company China big benefit group, rivers curtain wall is larger, and avic sanxin have strong competitiveness in the field of glass curtain wall.

It is one of the effective ways to reduce energy loss in China to popularize the use of exterior insulation. At present, the energy loss of houses in China is about 50 percent of the wall. Roofing about 10; Doors and Windows account for about 25; The basement and the ground make up about 15. Therefore, heat insulation of walls and roofs is an important link to improve the efficiency of building energy conservation. How to choose a safe and environmentally friendly wall insulation building materials is the key to the sound development of China's building energy conservation and insulation building materials industry.

Under the requirement of residential environment safety and environmental protection, China's building energy saving rate increases year by year. However, at present, thermal insulation materials for building in China, especially for external wall insulation materials, are mainly organic materials, among which, the market share of polystyrene is 90 and polyurethane is 10. However, due to the characteristics of materials and various fire prevention measures and management measures are not put in place, fire accidents occur from time to time.

In order to ensure safety, the ministry of housing and urban-rural development and the fire department of the ministry of public security jointly promulgated the interim regulations on external insulation and fire prevention of exterior wall decoration of civil buildings in September 2009. In this interim regulation, it is stipulated that the combustion performance of insulation materials used in residential buildings with A height greater than or equal to 100m, public buildings with A height greater than or equal to 50m, and curtain wall buildings with A height greater than or equal to 24m shall be grade A.

The so-called a-level refers to non-combustible materials, but at present, the popular building insulation materials in the market in China are mainly organic materials, even if the addition of flame retardants, the highest level can only reach B1. If the strict implementation of the history of zui strict fire order, it means that China's insulation materials industry will face a full range of shuffling or even elimination of the situation. Therefore, thermal insulation materials, especially external wall insulation materials have a considerable market capacity, can be engaged in external wall insulation materials to bring greater business opportunities.

Based on the analysis of the current demand of China's building insulation market, the annual demand will reach millions of tons at least, which is several times of the current output of China. The safe and environment-friendly exterior insulation material is the key material to realize disaster prevention and reduction, energy saving and consumption reduction. With the general improvement of the understanding of building safety and fire control, the demand for this material in the construction industry is growing rapidly.
