Of green energy-saving insulation materials market should be standardized

2013 insulation industry as a whole is relatively stable , there was no large industry technological innovation , there is no corporate news worthy of criticism . The only larger market trends is the government unveiled several policy papers on fire insulation materials , causing a larger social repercussions .

In recent years, many have occurred outside the building insulation materials fire , causing serious casualties and property losses, flammable combustible building insulation materials have become a new class of fire hazard , which caused the fire has shown multiple momentum.

Insulation and fire protection, both sides need to be unified in recent years, but fighting continued. Across policy sectors to regulate fire insulation material very seriously , since 2013 also introduced a series of related industry standards to regulate the market, but the effect seems to be far less obvious.

Public information, fire performance tests mandatory national standard National Standardization Management Committee late 2012 release GB8624-2012 " Classification of building materials and combustion products " and recommended national standard GB/T29416-2012 " building exterior insulation system methods " since October 1, 2013 implementation . Which require low flame retardant insulation panels will be difficult to get the B1 level assessment , the local government only allows the use of not less than B1 grade material is a big trend. Since then, Gansu Province, Department of Housing and Urban-Rural Development , Gansu Province Public Security Bureau in October 2013 jointly issued the most stringent performance specifications burning wall insulation . Requirements when building height greater than or equal to 50 meters, combustion performance of its external insulation materials should be A-level. Burning behavior and fire performance test methods currently implemented tightened wall insulation materials Huowang mouth, but also led the industry's new controversy.

Now several major specifications are walked , but are not introduced, including architectural design code for fire protection . China Association of energy-saving insulation materials , executive vice president Hu Xiaoyuan said wall insulation materials on fire safety regulations , without a ruler to volume, only the country according to their own circumstances, to develop appropriate rules and regulations.

Anyway, how have used . ZHU Chun-ling also said external wall insulation materials industry is more confusing, such as the lack of specific applications for the product technical specifications , mainly executed in accordance with article 46 . But not entirely around how to do both.

46 text refers September 2009 Ministry of Public Security and the Ministry of Housing and Urban-Rural Development jointly issued a "civil external wall insulation systems and fire Interim Provisions", the combustion performance of its provisions civil exterior insulation materials appropriate for the A level , and should not be less than the B2 level .Sellotape


With the 2010 Shanghai Jiaozhou Road 11 teachers apartment happen ? 15 fires during the 2011 Spring Festival in Shenyang Dynasty Wanxin building 2 ? 3 fires , higher wall insulation fire protection requirements on the agenda . March 2011 , Ministry of Public Security Fire Department issued a "further define civil insulation materials related to the requirements of the Fire Regulatory Notice" article 65 , the provisions of civil combustion performance of thermal insulation material used for the A -grade material. December 2012 and then the wind changed , the Ministry issued the Fire Department , " Fire insulation materials on civil matters related to the supervision and management ," which decided to terminate execution No. 65 paper .

From No. 46 to No. 65, the text message, and then the text of No. 350 issued , the corresponding material selection, from Class B to Class A, Class B and then , just four years, I am the foreign market has experienced a few wall insulation multi- downs. We can say that the introduction of the policy confusion and blur -oriented, to the confusion already in the exterior insulation market really add a fire . In the industry view , in the form of regulatory documents of this Executive Order professional field problems , it should be a temporary measure , a professional in the field of technical issues to technical specifications within the industry to solve, undoubtedly more scientific and reasonable.

For wall insulation fire , Technology and the Ministry of Housing Industrialization Development Center deputy chief engineer , deputy secretary general of China Association of Building Energy West Wei Yang , said by Fire Barrier and building height different for different insulation materials , can significantly reduce the possibility of fires sex .

He believes in the premise of ensuring the quality of the project , from the European experience, the life of a qualified EPS ( expanded polystyrene ) wall insulation can reach more than 40 years. Fire and wall insulation materials related to the construction phase occurs at about 85 , after the completion of the fire is less chance . In addition , the relevant standard requirements for insulation materials also increasingly comprehensive, insulation, moisture-proof , anti- pull , impact , etc., but also to focus on system solutions to ensure quality.Washi tape


Throughout the building materials industry system, it may be difficult to have a branch can be like exterior insulation material is so complex that even a clear industrial policy are difficult to unify and sustain. Investigate its crux , is also attributed to the overall strength in the existing , performance, exterior insulation material is difficult to co-existence . To take into account the building energy-saving insulation , or completely eliminate the fire hazard to tilt ? In most people, this is a non- solvers . That is why, I am the foreign market chaos wall insulation , companies mostly in blind obedience phase.

In this debate , in the end what kind of material can occupy an absolute advantage in the building's exterior wall systems , is still unable to conclude , in胡小媛it seems , no one wall insulation completely dominate the market , building external wall insulation system requires comprehensive coordination of material factors and fireproof insulation , construction technology. But the long-term development goals , the existing inorganic insulation materials research should focus on the production process to reduce energy consumption, limit emissions of dust and fiber , reduce the amount of bonding agent. Organic insulation materials research should focus on to find a more suitable blowing agents , flame retardant materials to improve and reduce the cost of production materials.

Currently, both from a technical , business or market environment , China's thermal insulation materials market there are still many blind spots and gaps. This not only highlights the imbalance in China's building materials market development , but also on the idea of building fire safety and building energy conservation technology presents new proposition. The main features of wall insulation is fire retardant , alkali resistance , corrosion , cracking , and good insulation effect . And wall insulation material in the construction of simple and easy . For insulation materials manufacturers , the current main task is to actively develop energy-saving and environmental protection, superior performance and flame retardant insulation effect good exterior insulation materials. But for now, the construction industry in terms of external wall insulation , wall insulation can say that the vast majority of materials are flammable type . Therefore, the development of new wall insulation is also facing great opportunities and challenges.

With the continuous compression of social life resources , environmental protection, energy saving construction industry to become the main tone . Vigorously promote green building insulation system , the development of energy-saving building wall insulation industry , not only to promote industrial upgrading and transformation of the mode of growth , stimulating the economy and stimulate domestic demand, and energy saving benefits arising subsequent to their initial pay far greater cost .Masking tape


In recent years, our green building wall insulation materials rapidly war, on the development of green energy saving wall insulation community has reached a consensus , if we maintain the annual construction project 200 , the gradual establishment of management systems and standards , as well as solar photovoltaic , LED prices gradual decline in both green building and construction will provide good conditions for the development of energy-saving . Promote green building and energy efficiency in buildings , new buildings must first raise the proportion of green building . Secondly, we must accelerate energy-saving public buildings. Start of 2012 public building energy-saving demonstrations in major cities , transforming the area of the first Shenzhen , Chongqing, Tianjin three cities are expected to be more than 12 million square meters . The future goal is to 2016 , focusing on urban public building energy consumption per unit area decreased by 20 or more.Wholesale masking tape
