insulation materials

[hhmee]

Rockwool insulation materials are widely used in foreign countries Currently building energy consumption has accounted for 27.5 percent of the country's total energy consumption, given the importance of energy efficiency in buildings, the Ministry of Construction had been proposed three stages of development of energy-saving target of building: 1996 years ago (1988 onwards Enforcement), New residential timber wall cladding sold in cape town building at 1980 to 1981 local universal design energy consumption reduced by 30% on the basis of universal, namely saving 30%; 1996, reached on the basis of the first stage and then save 30% or 50% energy saving, which 30% by thermal insulation performance of the building envelope to reach the other 20% by increasing efficiency stove and outdoor heating pipe network to achieve; in 2005, reaching the second stage, based on the re-saving 30%, namely saving 65%.

Previously, the relevant departments not to save 30% of the standard in place, real estate agency for energy-conscious building desalination market has been bland and really engage in external wall insulation energy business is not much. Along with the increasing emphasis on building energy conservation issues, building energy-saving wall insulation industry more and more attention. Throughout the real estate and construction industry were focused on the deployment, a number of related policies, even for non-compliance of building energy efficiency will not be approved. Especially in China's energy efficiency goals, "Eleventh Five-Year", the contribution rate of building energy efficiency to reach 20%, it will take to save 120 million tons of standard coal.

The analysis showed that from abroad, the outer envelope of the heat loss through the façade accounted for 50%, while domestic ratio of 46%, based on the external wall insulation has an important role in building energy efficiency, in order to implement the "five" target 2009 work will focus on building insulation around wall insulation is expanded. Recently, the international the plastic board sat lowes authority of the market research firm released a report on China's construction industry, "China building insulation market," and that from now until 2011, thanks to China's booming construction market and the prevalence of insulation materials, insulation materials expected demand grow at an annual growth rate of 9 percent development in 2011 will reach 2.84 billion.
