Energy-saving windows and doors are a professional pace for the market

stone coated metal roofing tile related news

With the popularization of energy-saving knowledge , we have the energy saving features of the product are more and more attention . Currently windows and doors industry also is increasing its efforts to enhance energy-saving ideas, promote energy brand. " Windows Doctor" after an investigation found doors today in the energy industry professional road farther , concrete can be seen from the following aspects. stone coated metal roofing tile

Strict construction of energy-saving windows and doors to ensure system effectiveness

China experienced a traditional door and window industry turn wooden windows , steel windows, aluminum windows , steel doors , composite doors simple stage of development , currently on the market mainstream products are solid wood doors and windows , aluminum clad wood , aluminum composite wood , copper clad wood , glass curtain wall , sun room , aluminum forging bar , steel , high-grade steel and so on. stone coated metal roofing tile

Energy-saving windows and doors are tailor-made products, in addition to a special processing technology , process complex, precision equipment , the production installation and construction and installation are demanding. Installing energy-efficient windows and doors in terms of performance can occupy the first play of various factors , signifying its importance . To do this , companies need to establish a dedicated construction team. Installation of doors and windows in general proficiency requirements for workers , requires a two-year training , practical experience can be achieved. The energy-saving windows and doors installation requirements , especially high-grade , high -quality products to install more demanding . stone coated metal roofing tile

Rise in second-tier cities developer brand concept Forced raise the standard first-line

Due to the geographical environment around the windows and doors as well as differences in the degree of awareness of energy conservation , energy-saving windows and doors throughout the building effect of the requirements are very different . Chongqing Northeast and if the value of K ( Note : K value, i.e. the greater the heat transfer coefficient K value , the more heat transfer , the poorer performance of thermal insulation value K is smaller , the less heat is transferred to the thermal insulation . better performance ) was 2.2 , Tianjin is 1.5-2.7 , Hebei Province, to develop a K value of 2.5 .

However, there are some second-tier cities in construction projects using energy savings beyond the first-tier cities has become a trend in the standard product . Such as Nanjing, Jiangsu Province , and its surrounding Yangzhou , Changzhou, Wuxi and other places of the widespread use of the new buildings shading systems and high-end energy-saving windows , doors and K value of 1.9 or less , and now Beijing windows standard K value of 2.8 . stone coated metal roofing tile

Beijing will increase energy efficiency doors and windows

" China's current energy efficiency standards for basic windows behind Europe for 30 years ." Professionals raised . K is the current European standard windows 1.3 . Currently the average K value of the doors and windows of about 3.5 , Beijing K value of only 2.8 standard doors , windows and doors in Europe 1984 K value of the standard .

In Copenhagen, the developed countries and regions standards for energy-saving windows put forward higher requirements . Germany plans to enhance the value in 2012 to 0.8 K , the EU will implement the new standard K value of 0.9 . The United States and France were planned in 2015 and 2017 , will not meet energy efficiency standards for windows to be replaced.

With the "energy saving" our leaders promise made ​​at the Copenhagen conference , our doors and windows to improve energy efficiency standards is imperative . Beijing windows to improve energy efficiency standards have been discussed in the expert stage, the plan will raise energy efficiency standards for building windows and doors in Beijing to three of the following building K value of 1.5 , three to six-story building K value of 1.8 , more than six architectural value of 2.1 K .

Insiders said that with the policy attention and enhance consumer acceptance of energy-saving windows and doors , and energy-efficient windows and doors in the spring has come.
