High quality doors and windows = high quality profiles + glass + accessories strip + processing technology + installation process +...

High-performance doors and windows = high-performance profiles × glass × accessories strips × processing × installation process ×...

So: High quality doors, windows, high performance doors and windows

Now with the continuous improvement of the quality of life, people have clear requirements for the quality and performance of residential buildings. The energy-saving performance, safety performance, noise reduction, sun protection, comfort, and durability of buildings and doors are increasingly valued. In addition to focusing on the quality of doors and windows, such as aluminum, glass, and accessories, building doors and windows products are more concerned with the realization of a comprehensive performance after the combination of these door and window components.

The real system door and window is a perfect organic combination of performance systems. It needs to consider a series of important issues such as watertightness, airtightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weather resistance, and operational feel. Function, but also consider the comprehensive results of the performance of the equipment, profiles, accessories, glass, viscose, seals, are indispensable, and ultimately the formation of high-performance system doors and windows.

At present, in the building materials market, the use of high-end broken bridge aluminum alloy doors and windows, has gradually become the first choice for many high-end architectural windows. However, experts also pointed out that the quality of aluminum alloy doors and windows on the market is uneven, and must be carefully selected when purchasing. Inferior quality aluminum alloy doors and windows, blind selection of aluminum profiles and specifications, rough processing, and saw cutting instead of milling, not installed as required, poor sealing performance, switches are not comfortable, not only leakage of air leakage and glass burst phenomenon, but also To strong winds and external forces, it is easy to scrape or touch the push-pull part or glass, destroying things and hurting people. The high quality aluminum alloy doors and windows used in aluminum, thickness, strength and oxide film, etc., should comply with relevant national standards, wall thickness should be more than 1.2 mm, tensile strength of 157 newtons per square meter mm, yield strength to achieve At 108 Newtons per square millimeter, the thickness of the oxide film should reach 10 microns. If it fails to meet the above criteria, inferior aluminum alloy doors and windows cannot be used.

Why does China need to introduce high performance system doors and windows in Europe?

From the beginning of modern architecture, doors and windows industry began to develop in the early 1980s, it has experienced nearly 30 years of baptism and evolution in the market. Ordinary doors and windows with poor performance have always occupied the dominant position in the Chinese market. The upgrading of Chinese doors and windows technology is relatively slow, and building doors and windows have become Large energy-consuming households in China's buildings will in the future also be large energy users!

Europe had developed high-performance system doors and windows as early as the 1980s, and its energy-saving performance, safety performance, and comfort far exceeded those of ordinary windows and doors.

In 2003, the European standard for doors and windows required a K value of not more than 1.4. High-performance system doors and windows were more popular. Currently, the market application has reached 70% of the total amount of doors and windows, while the average K value of doors and windows in China is about 3.5 (insulation). The current highest standard, Beijing's standard for doors and windows, is a K value of 2.8, which is only the K value standard for doors and windows in Europe in 1984. According to calculations, according to China's existing urban construction area of ​​about 43 billion square meters, if the implementation of the European current standard K value of doors and windows, annual savings of 430 million tons of standard coal, about 20% of China's annual coal production, the amount is quite alarming.

European system doors and windows entered the Chinese market in the late 1990s. Now the European high-performance K-value standard for doors and windows can reach 0.8, and its energy consumption is basically only 1/4 of the energy consumption of building windows and doors in China.

“Low-carbon” was the theme of the Copenhagen World Climate Conference at the end of 2009. At the meeting, countries launched their respective energy-saving and emission-reduction targets. China promised that by 2020, China’s CO2 emissions per unit of GDP will fall by 40%-45% compared to 2005, and As a binding indicator, it is included in the long-term plan for national economic and social development. This means that China must adopt practical energy-saving measures in various economic sectors of society in order to achieve its intended goals. At present, building energy consumption has accounted for 40% of China's total energy consumption of the entire society; while energy consumption for windows and doors accounts for 45% to 50% of building energy consumption, and accounts for 15%-20% of total social energy consumption. It can be seen that doors and windows are the main cause of building energy loss, and the upgrading of building energy-saving doors and windows will be the trend of the times.

Therefore, we must improve the insulation effect of doors and windows in all aspects, and guide everyone to use high-quality energy-saving doors and windows. While China's door and window technology has not yet reached a high level, European high-performance system doors and windows have become China's first choice for energy-saving doors and windows!

What is the purpose of system door and window energy saving?

1. Protect the health of occupants by creating a healthy and comfortable environment;

2. Protect the building structure and decoration structure from the natural condensation or rain in the air;

3, reduce the energy consumption of heating and air conditioning;

4. Reduce maintenance and operating costs.

Are the system doors and windows really expensive?

1. As the system doors and windows are increasingly recognized by the market, the gradual expansion of the market makes its overall cost less and less. At present, the prices of good system doors and windows in the market are about 1,000 yuan/square meter, and the price is only higher than that of high quality. Doors and windows are roughly 200 yuan per square meter or so, such as Beijing, Shanghai and other first-line cities, the current real estate price is 2 to 4 million yuan per square meter, second-tier cities are 8,000 to 15,000 yuan, even if the new real estate will be replaced by ordinary doors and windows high-performance system doors and windows, Each square meter only needs to increase by 100-300 yuan. Although the system doors and windows are slightly more expensive than ordinary windows and doors, the cost per square meter of allocated housing price is still very limited. In order for residential products to be sold quickly, many real estate developers are fully able to withstand this. A premium.

2. With the combination of property market control policies, the state will gradually rectify the real estate market to a certain extent, curb housing prices, launch a large number of affordable housing, cheap housing, and limit prices to stabilize the market. The housing is not in short supply, house prices are down, the house is unsalable, and real estate developers need to look for selling points in the quality and function of their homes. Whoever is more willing to please consumers is more likely to sell residential products.

3. Building doors and windows as an important part of the overall function of the building, will also benefit from more and more attention by real estate developers, improve the performance of doors and windows, the use of high-performance system doors and windows will also become an important selling point for real estate developers selling residential products one.

System door and window energy saving example

Example: 100m2 of two rooms and one hall, window area of ​​about 30m2. System doors and windows have better insulation than ordinary doors and windows.

Let's calculate the relevant data:

condition:

1. Use an ordinary door and window to open the air conditioner every day, and the power consumption is 30°.

2, open the air conditioner with the system door and window every day, the power consumption is 25 degrees.

3. Calculate the electricity fee at 1 yuan/hour. System window 1200 yuan / square meter, ordinary doors and windows 800 yuan / square meter.

Open air-conditioning every year to save costs: (30 ° -25 °) * 365 * 1 = 1825 yuan.

Door and window cost difference: system door and window cost - ordinary door and window cost = 30*1200-30*800 = 12,000 yuan.

As a result, the calculation is 12000÷1825≈6.5 years!

The general design life of a residential building is 70 years. We can use only 6 years to recover the cost of building windows. The system doors and windows make the building energy-saving and efficiency increase for 64 years!
