Are high-end doors and windows not particularly expensive? What is the price range of high-end doors and windows market? How is it calculated?
The price of high-end doors and windows is relatively expensive. The price of high-end doors and windows products in the market ranges from 1600 to 4000, calculated per square meter.
Characteristics of high grade doors and windows
First, the physical properties of its doors and windows are good. The performance of the door and window, such as air tightness, air tightness and water tightness. The wind pressure resistance performance of doors and windows reflects the safety of doors and windows. High grade doors and windows must be doors and windows with high safety performance. In the standard, the wind pressure resistance performance of doors and windows can be divided into nine levels, from 1kPa to 5kpa, which should meet the wind pressure resistance performance requirements of different buildings in different areas. High grade doors and windows combine the advantages of aluminum alloy window and wood window. The outdoor part is made of aluminum alloy, which is easy to form, has long service life and rich colors. The surface can be sprayed with powder spray, fluorocarbon spraying, anodizing, electrophoretic painting, waterproof, dustproof and UV proof; The interior adopts high-grade and high-quality wood processed by special technology. It has various colors and provides numerous patterns. It can coordinate with various interior decoration styles and play a special decorative role. It is a new type of doors and windows with new heat preservation and heat insulation, and has an excellent development prospect.
Second, the air tightness and thermal insulation of doors and windows are important indicators of the performance of doors and windows. Energy saving of doors and windows is mainly reflected in the air tightness and thermal insulation performance of doors and windows. As a high-grade window, its prerequisite must be good energy-saving windows and doors. As we all know, the building energy consumption has accounted for 40% of the total social energy consumption, and the energy consumption of doors and windows accounts for 50% of the building energy consumption. Therefore, it is very important to pay attention to the energy conservation and consumption reduction of doors and windows to achieve the goal of energy conservation and emission reduction. On June 14, 2012, Beijing Municipal Bureau of quality and technical supervision and Beijing Municipal Planning Commission jointly issued the design standard for energy efficiency of residential buildings (DB11 ／ 891-2012), which will be implemented from January 1, 2013. The standard stipulates that the heat transfer coefficient limit of building external windows should be between 1.8 ~ 2.0W / m2 · K. It is reported that the heat transfer coefficient limit of external windows in Europe is 1.3w/m2 · K. In 2012, Germany has raised the heat transfer coefficient limit of building external windows to less than 1.0W / m2 · K, and the European Union will implement the new standard of 0.9W / m2 · K. The relevant countries (regions) attach so much importance to the limit value of heat transfer coefficient of building doors and windows, which shows that the air tightness and thermal insulation of doors and windows are important to building energy conservation.
Third, high-grade windows must have high water tightness. The measurement index of water tightness performance is the maximum pressure of leakage of doors and windows. Generally, the watertight performance of doors and windows is not less than 250pa, but as a high-grade window, its watertight performance is not less than 350pa.
Fourth, high-grade windows must have high sound insulation performance. The sound insulation performance of doors and windows is the ability of doors and windows to block external sound. The sound insulation performance of high-grade windows should not be less than 35dB.
Fifthly, high-grade doors and windows must be high-quality windows. High grade windows should have high configuration in the use of materials, selection of accessories and surface treatment. The selection of hardware and sealant strips should meet the needs of door and window functions, performance and service life. High quality high-grade windows are the perfect collection of materials, technology, technology and installation, which can reflect high-quality high-end doors and windows.
The difference between ordinary doors and windows and high-grade doors and windows?
Any product has its own value. Let's make a comparison. Suppose your friend's home is equipped with ordinary doors and windows of several hundred yuan per square meter on the market. We all know that the service life of ordinary screen windows is generally about two years. If it is 50 years, I will not calculate the price increase and dimension in the later market The total cost of protection is about 100000 yuan. On the contrary, if you use the new high-grade doors and windows with mosquito proof and anti-theft of Jinmei home furnishing company, the cost will be more than 20000 yuan if calculated by 10 square meters.
