Aluminum-plastic composite doors and windows to catch the energy market "swim"

Under the promotion of building energy conservation policies, a large number of new types of environmental protection and energy-saving products such as aluminum alloy energy-saving doors and windows, glass and steel energy-saving doors and windows, and aluminum-plastic composite doors and windows continue to emerge, and new products emerge one after another. According to incomplete statistics, the market share of building energy-saving doors and windows in various places has been increasing rapidly, accounting for 50% of the entire window and door market. Therefore, vigorously developing energy-saving doors and windows, whether it is economic or social benefits, are very large.

As an important part of building energy conservation, doors and windows can cooperate with the wall to play a good role in thermal insulation and reduce the loss of energy in the house, which plays a crucial role in building energy conservation and emission reduction. At present, many types of doors and windows, showing aluminum, plastic, steel, wood, glass steel, aluminum-plastic composite, aluminum-wood composite development trend. In order to cater for building energy conservation policies, manufacturers of various types of door and window materials, after making slight improvements, have already taken trains with energy-saving doors and windows.

Whether the windows and doors are energy-efficient depends on two aspects:

First: What is the material of the window frame and sash frame, and whether it is insulated or not.

Second: Whether the glass uses hollow glass is the most basic requirement.

Obviously, aluminum alloys, color steel and other metal materials have high heat transfer coefficients, do not heat insulation and heat insulation, plastics and glass steel materials have low heat transfer coefficients, heat insulation and heat insulation, which is also common sense. Therefore, the conclusion is very clear, plastic and FRP materials with the door and window made of insulating glass is thermal insulation energy-saving doors and windows. Aluminum alloy frame with insulating glass is not energy-saving doors and windows. The problem is far from simple.

Although plastic doors and windows have good insulation and energy-saving properties, they have the disadvantages of single colors, fading after dyeing, and rough frames. In addition, these years, there is a lack of supervision over the shoddy production of workshops. There is a plastic window that is low-grade goods in people's consciousness. The misunderstandings made general developers unwilling to adopt plastic windows. The promotion of glass steel doors and windows is weak, few people are interested. Looking at the other side of the question, aluminum alloy doors and windows are not energy-efficient, but their appearance is very scratchy and elegant, and their colors are rich and colorful, and they are not easy to fade, giving people a deep impression on aluminum doors and windows, that is, high-grade doors and windows, and are deeply ingrained. .

In view of this, manufacturers of aluminum alloy profiles have introduced broken-bridge heat-insulating aluminum alloy profiles. Doors and windows made of such profiles are called energy-saving doors and windows. Broken bridge insulated aluminum doors and windows have a certain degree of thermal insulation, but not energy-saving doors and windows. Its thermal insulation efficiency is limited and essentially belongs to metal doors and windows. After testing, the thermal performance of broken aluminum alloy doors and windows of the broken bridge is far from the requirements.

So, does it have the advantages of both plastic doors and windows insulation and energy conservation, but also has the appearance of aluminum alloy doors and windows, and the popular varieties of doors and windows? The answer is yes. Aluminum-plastic composite doors and windows not only possess the characteristics of aluminum alloy doors and windows, but also have the advantages of good thermal insulation and energy saving of plastic doors and windows. At the same time, due to the use of aluminum alloy frame embedded in the abdominal cavity of the plastic frame, the plastic profiles are wrapped around the aluminum alloy profiles after welding, while retaining the advantages of plastic doors and windows not leaking into the wall, eliminating the hard-to-solve spell angle of aluminum alloy doors and windows for a long time. The problem of water seepage reached the insulation effect.

Aluminum-plastic composite doors and windows in the application continue to sum up experience and continuous improvement, this insulation energy-saving effect is obvious, the appearance of popular, resource-saving, economical energy-saving doors and windows can be an architectural design in the energy-saving doors and windows selection of outstanding Variety.
