What is the doors and Windows system?

Most people are of the opinion that purchase high quality doors and Windows, pay attention to doors and Windows parts such as the quality of the aluminum, glass, accessories, and some professional performance requirements for Windows and doors don't know, is paid more attention to product quality, price and other factors, the initial consumption ideology is considered high quality doors and Windows is a high-performance Windows and doors.

High quality Windows and doors = high quality profile + accessories strip + + glass processing installation technology + +...

High performance Windows and doors = high performance profiles * accessories strip * glass processing process x installation process x...

So: high quality Windows and doors indicates the high performance of Windows and doors

Now with the constant improvement of the quality of life, people have a clear request for housing quality and performance, energy saving performance of building doors and Windows, security, performance, sound insulation, noise reduction, sun protection, comfort and durability is taken seriously more and more, in addition to pay attention to when buying building doors and Windows products doors and Windows parts such as the quality of the aluminum, glass, accessories, relative pay more attention to these doors and Windows components combination after the implementation of a comprehensive performance.

Window of door of the real system, it is a perfect organic combination of performance system, need to consider the water tightness, air tightness and wind resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weatherability, handle and a series of important function, but also equipment, material, accessories, glass, viscose, tight sealing a comprehensive result of performance of each link, be short of one cannot, eventually form a system of high performance Windows and doors.

On the building materials market at present, the use of high-grade aluminum alloy doors and Windows broken bridge across profile, has gradually become many of choice for high-grade architectural Windows products. But experts also pointed out that at present, the products in aluminum alloy doors and Windows are of variable quality, must be careful to distinguish when the choose and buy. Inferior aluminium alloy door, choose aluminous profile series and norms blindly, processed and manufactured in order to curium cut replaces mill processing, not according to the requirements for installation, sealed performance is poor, switch does not freely, not only rain of air leak leakage and occurrence glass blast crack phenomenon, and encounter blast and outside force, blow push-pull part or glass easily fall or touch fall, destroy content cuts. And high quality aluminum alloy doors and Windows with aluminum, thickness, intensity and oxidation film, etc., shall comply with the relevant standards of the provisions of the state, the wall thickness should be in 1.2 millimeter above, tensile strength of millimeter of every square metre 157 Newton, succumb intensity should achieve every square millimeter 108 Newton, oxidation film ply should achieve 10 micron. If standard of short of above, it is inferior aluminium alloy door window, cannot use.

Why China high-performance systems doors and Windows need to introduce Europe?

From the development of modern building doors and Windows industry started in the early 80 s to date, has experienced nearly 30 years of market baptism and evolution, the common door window with poor performance always has dominated the Chinese market, China's doors and Windows technology upgrading is relatively slow, building doors and Windows to become China's construction of large energy consumption, the result of the future is also a large energy saving!

Europe has developed in the 1980 s and early doors and Windows with high performance system, the energy saving performance, safety, comfort and so on far more than ordinary Windows and doors. 2003 European doors and Windows in the standard requirement of the K value is not greater than 1.4, the high performance system of doors and Windows more popular, the market at present are 70% of the total has reached the doors and Windows, and doors and Windows in China an average of about 3.5 K value (insulation), the highest standards of China - Beijing doors and Windows standard is 2.8 K value, only for the European doors and Windows 1984 K value standard. According to the calculation, according to China's existing urban construction area of about 43 billion square meters Calculation, if the European standard of door window K value, the can save 430 million tons of standard coal each year, approximately 20% of the total output of coal in China, the number is quite amazing.

European system doors and Windows in the late 90 s to enter the Chinese market, now European high-performance system Windows standard can reach 0.8 K value, the basic energy consumption only a quarter of our country's energy consumption of building doors and Windows.

"Low carbon" is the theme of the world climate conference in Copenhagen at the end of 2009, countries launched their own energy conservation and emissions reduction targets at the meeting, China's commitment to the 2020 unit of gross domestic product (GDP) of carbon dioxide emissions 40% to 40% lower than in 2005, and as a binding forces into the national economic and social development in the medium to long term planning. This means that our country must in all areas of the economy of the society to take concrete measures to conserve energy, to achieve the scheduled target. At present, building energy consumption has accounted for 40% of the total energy consumption of the whole society in our country. The doors and Windows and accounts for 45% ~ 50% of building energy consumption, energy consumption accounts for 15% ~ 15% of total energy consumption society. Visible Windows and doors is the main cause of energy loss, upgrading of building energy-saving Windows and doors will be the trend of The Times.

Therefore, we must improve the effect of heat insulation of Windows and doors in each aspect, guides everybody to use high-quality energy-saving Windows and doors, the Windows and doors technology in China has not yet reached a high level of at the same time, the European high performance system of doors and Windows become the choice of China's energy-saving Windows and doors.

What is the purpose of energy saving doors and Windows?

1, through to build a healthy and comfortable environment, protect the health of residents;

2, protect the structure and decoration construction from naturally occurring in the air condensed water or rain destruction;

3, reduce heating and air conditioning energy consumption;

4, reduce maintenance and operating costs.

Doors and Windows system really expensive?

1, doors and Windows as the system is more and more recognized by the market, the market gradually expanding its comprehensive cost less and less, the better system of Windows and doors on the market at present the price about 1000 yuan/square meters, the prices are more expensive than the common door window with high quality only roughly around 200 yuan per square meter, first-tier cities like Beijing, Shanghai real estate prices are now a 1 ~ 30000 yuan per square meter, second-tier cities for 3000 ~ 10000 yuan, if the new buildings will be replaced ordinary Windows doors and Windows for high performance system, need to increase 100 ~ 300 yuan per square meter, Windows system although than ordinary Windows is a bit expensive, but the contribution to the cost of housing price per square foot is very limited, for the sake of residential products quickly, many real estate developers are completely have the ability to bear the premium.

2, with the combination of housing market regulation policy, countries will gradually straighten out the real estate market to a certain extent, rein in property prices, to launch a lot of affordable housing, low-cost housing, slow market price room. Houses not shortage, house prices came down, the house unsalable, real estate developers will need to be up in the residential quality and function for selling point, who can more to please customers who sell residential product.

3, building doors and Windows as building the overall function of an important part of, also will benefit more and more get the attention of the real estate, improve the performance of the doors and Windows, using a high performance system of Windows and doors will be real estate developers sell residential products one of the important selling point.

Energy saving doors and Windows, for example

Example: 100 m2 of two rooms one hall, window area around 30 m2. Doors and Windows insulation performance is better than that of ordinary doors and Windows.

We to calculate the relevant data:

Condition:

1, using ordinary Windows every day open air conditioning, power consumption is 30 °.

2, with Windows and doors every day open air conditioning system, power consumption is 25 °.

3, electricity as 1 yuan/hour. Window system 1200 yuan/square meters, ordinary doors and Windows 800 yuan/square meters.

Annual air conditioning cost savings: (30 ° and 25 °) * 365 * 1 = RMB 1825.

Windows and doors Windows cost difference: system cost - ordinary Windows and doors = 30 * 30 * 800 = 1200-1200 yuan.

As a result, 12000 present 12000 material 6.5 years!

Housing a fixed number of year of the general design of 70 years, we can take back only six years beyond the cost of building a window, doors and Windows system make building energy efficiency in 64.
