Simple comparison shows that the cost and unit price of domestic and imported system doors and windows are higher than that of ordinary broken bridge aluminum golden doors and windows. But for every penny, the windows and doors of the system are "expensive" in the form of profiles and hardware, as well as in research and development, design, post-service, comprehensive performance and so on. Its performance is excellent, easy to operate, long time to use, so in general, the cost of the system doors and windows is actually lower.

Domestic enterprises engaged in system research and development have few own laboratories, but foreign systems door and window enterprises have established their own perfect R&D system. At the same time, the maximum cost is not the profile accessories but R&D costs. The output products are about the technology of system doors and windows, not the door and window products. This is also the system at home and abroad. There are differences and gaps in the research and development of doors and windows. At present, the application of system doors and windows in Europe is nearly 80%, but the actual application in China is not more than 1%. Most of them are plastic steel and ordinary aluminum alloy doors and windows with poor performance. Although the market demand for high-performance doors and windows is expanding constantly, few domestic system doors and windows enterprises have truly formed brand effect.

Huang Bian, Director of Aluminum Door and Window Curtain Wall Committee of China Building Metal Structure Association, said: "The most scarce thing in the current door and window system industry is the large-scale enterprises, because it requires a lot of money and energy to focus on the research and development of the door and window system. If the leading enterprises in the industry can develop the related system technology, they will cooperate in the demand of the industry or Transfer of this technology is currently one of the most effective ways to enhance the development of the whole system door and window industry in China.

The birth of doors and windows is not accidental, but the emergence of system doors and windows in China can not rule out the accidental factors. The most core connotation of system doors and windows is the technical application of "systematization". Systematization technology is not completed by assembling. What really "defeats" the national standard is that system technology is not a component. From "fragmentation concept" to "independent standard" market, from "high investment, low return" to "considerable premium profit", the development of door and window system industry in China has a long way to go.

Most people think that buying high-quality doors and windows, focusing on the quality of the obvious parts of doors and windows, such as aluminium, glass, accessories, etc., is OK, but they do not understand the professional performance requirements of doors and windows at all, and pay more attention to factors such as product quality, cost-effective ratio, etc. In the initial consumption ideology, they think that high-quality doors and windows are equal to high-quality doors and windows. Performance windows and doors.

Window Opening Mode

Push-and-pull window: Now the most used way to open windows.

Advantages: No indoor space, easy to install and use curtains

Disadvantage: Can not open at the same time, ventilation is slightly worse, sealing is relatively poor, so the sound insulation, dust insulation is poor. Flat window: Double or three-layer hollow glass can be installed generally.

Advantages: large opening area, better sealing performance than push-pull type, good sound insulation and heat preservation, suitable for areas with high street noise, easy scrubbing.

Disadvantages: Opening in occupies indoor space, hinders the use of curtains, and is not convenient to install screens and fences outside. It is easy to be damaged or even fall when the wind blows. It has potential safety hazards and its price is higher than push-pull windows.

Upper and lower suspension windows:

Advantages: Open the window of the small gap, people can not pass, safer. It occupies small space and is suitable for places with limited installation location such as kitchen and bathroom.

Disadvantage: The opening gap is small, so the ventilation is not very good.

Hardware Selection

Hardware directly affects the flexibility, airtightness and service life of window opening. It can not be chosen carelessly.

About selection: Choosing well-known hardware brand can greatly improve the use experience and service life. Hardware for windows includes handles, drives, seals, hinges, wind braces and so on. They are generally sold by kits, and irregular businessmen sell by parts.

Commonly used hardware materials and price differences: stainless steel > zinc alloy > aluminum alloy.

2. Attention should be paid to the selection of materials for sunroom:

The reason is called sunshine room, it must be inseparable from the sunshine. So ah, the main structure of the material must be well selected, as for the selection of materials, we recommend that you take glass as the main material. When we choose glass materials, we should also pay attention to the selection of insulation, sound insulation and so on. In addition to the need for glass as the main material, the sunshine room also needs the help of the structure frame to shape, glass. There must be columns around the structure of the house. Aluminum alloy square pipe columns can be selected for the structure frame, and the other square pipe roof square pipes can be installed in two directions. In this way, the sunshine can be fully irradiated, and it is also safe and firm.

3. Attention should be paid to the thermal insulation of the sunroom.

In summer, if we don't insulate the sunroom, we will live in a steamer. Therefore, here Xiaobian should remind us that the insulation of the sunshine room is also something we need to pay attention to. Because the sunshine room is made of glass on the roof, it will be very hot in summer under the intense sunshine, so we need to heat insulation when making the sunshine room, and the insulation can be used by everyone. Glass insulation film is mounted on top glass. Because the surface of the insulation film is coated with a dark reflective material, the sunlight can be reflected out, so as to achieve the effect of insulation. Installation of heat insulation film on glass can improve the glass's energy, reduce the glass's permeability, reflect the sunlight, and realize the heat insulation function. High density rubber-plastic aluminium foil heat insulation board can also be laid on the top glass surface, and a silent ventilation fan can be set in the appropriate place for ceiling heat insulation. The air duct can lead to the outdoor. Double curtain of aluminium alloy window can be set, and light and heat insulation of the bottom curtain can be set.

How can sunshine houses prevent earthquakes? Obviously, people's favorite thing for different architectural designs is to be able to prevent earthquakes. Every time we publicize real estate, there are a lot of builders who come to explain their ability to build houses and protect against earthquakes. How many protective skills do you have in the construction process? How can we really understand this seismic capability?

In different urban areas, you can see that more and more people for the design of sunshine houses, but also must be designed in accordance with our scientific and technological standards. Earthquake-resistant design is actually necessary for most people. People live in a comfortable world for a long time, so they are more and more afraid of natural disasters. People are in awe of nature because we want to make better use of it to help us understand the world. So for the construction of sunshine houses, most people want to be able to watch earthquakes with magnitude 6 or above.

And this design is the most basic design concept, so whether from steel frame structure or using ordinary plastic-steel structure, we must choose the most suitable glass for our own construction conditions. Of course, we must use glass for construction, for such glass selection, in addition to the use of polymers, there is no other choice. So different people for the design concept, usually in accordance with our design effect to understand. Many people can see a variety of design models in the company, so what kind of assurance can design models give us? We can use design models for seismic drilling. Earthquake drills can ensure that we make better market choices, and we can also have a more reassuring choice for the choice of such houses.

There are two kinds of waterproofing methods for sunshine houses. One is to use the slope of sunshine houses to quickly drain the rainwater from the roof so as to minimize the possibility of leakage. Secondly, waterproof materials are used to plug the gap between glass and rods, and seamless and porous are required to prevent rainwater leakage.

Among them, the first is the main aspect, which has good waterproofing effect and saves labor and materials. Therefore, when dealing with the waterproofing of sunshine houses comprehensively, the first one should be given priority to, and the second one should be supplemented by, the combination of the two. No matter what style of sunshine room drainage is very important, because if the design of sunshine room drainage system is disordered or the details of drainage are not properly handled, resulting in poor drainage or water accumulation, are all factors causing leakage, long-term water accumulation will make sealant aging, so the drainage problem of sunshine room should be paid enough attention. The company's professional sunshine room design, production manufacturers, comprehensive waterproofing of the sunshine room, designed a unique sunshine room drainage system and sealing, so that the sunshine room does not leak for life.
