There are two kinds of aluminum alloy windows: ordinary aluminum alloy windows and broken bridge aluminum alloy windows. Aluminum alloy windows are beautiful, sealed and high in strength, and are widely used in the field of building engineering. In home decoration, aluminum alloy windows are often used to encapsulate balconies.

1. Is there a difference between aluminum-magnesium alloy, plastic-steel doors and windows, aluminum-wood composite, colored aluminum and glass fiber reinforced plastic?

sometimes, I often go to some mainstream search engines such as Baidu or google to search for some information about plastic steel doors and windows, broken bridge aluminum alloy windows, etc., and I often meet more friends who have many technical terms, or don't understand the knowledge of door and window decoration, and I get such a question in google's search: Is there a difference between aluminum-magnesium alloy, plastic steel doors and windows, aluminum-wood composite, colored aluminum and glass fiber reinforced plastic? To this end, I specially inquired a lot of information and professional knowledge of doors and windows from search engines with extensive information such as google, Baidu and Yahoo, and summed up the following points for the reference of the majority of owners and friends.

second, which is better, broken bridge aluminum alloy window or plastic steel door window?

firstly, if the price is not considered, the broken bridge aluminum alloy window should be the best window structure. However, many broken bridge aluminum alloy window profiles on the market now cost only 3 to 4 yuan per square meter, but the actual broken bridge aluminum alloy window is more than 8 yuan per square meter in terms of materials (if it is directly made by a manufacturer, it is generally above 5 yuan, and if it is a building material city, the exhibition hall is generally at least 8 yuan/square meter)

Thirdly, the broken bridge aluminum alloy window.

heat insulation broken bridge aluminum alloy window is an improvement based on the old aluminum alloy window to improve the heat insulation and heat insulation performance of doors and windows. The aluminum alloy profile is divided into two parts, the inner part and the outer part, by strengthening nylon spacers, which blocks the heat conduction of aluminum. The material and quality of reinforced nylon spacers directly affect the durability of aluminum alloy windows with thermal insulation and broken bridges.

fourth, is the sound insulation effect of aluminum alloy window with hollow broken bridge good?

The aluminum alloy window profile with broken bridge is significant for the heat insulation of the window, but not for the sound insulation. Therefore, if the size is appropriate and the workmanship is the same, the sound insulation effect of the two windows should be the same, and the effect will be better if vacuum glass is used.

5. Why do high-rise buildings often use broken bridge aluminum alloy windows?

1, light weight and high strength. ? The density is only 1/3 of that of steel.

2, it is not doped with many precious metals, so it has good corrosion resistance.

3, good sealing performance. The sealing performance directly affects the use function and energy consumption of aluminum alloy windows. ? The sealing performance includes air tightness, water tightness, heat insulation and sound insulation.

VI. What are the famous brands of broken bridge aluminum alloy window in China?

At present, the mainstream broken bridge aluminum alloy window brands in the market are: Guangdong Fenglv, Beijing Heping, Beixin, Central Asia,. Relatively speaking, Guangdong Feng Aluminum and Guangdong Zhongya Broken Bridge aluminum profiles are relatively well-known in China at present.

VII. What are the advantages and characteristics of aluminum alloy window profiles with thermal insulation and broken bridges?

1. There are three categories: anodic oxidation, electrophoretic painting and powder spraying. There are rich varieties and excellent ones: Three properties, ideal energy-saving sound insulation effect, which can be called the essence of modern door and window materials.

2. Excellent energy-saving effect. K. Value is 2.-3.W/M2K. Energy saving is 3%-4%? 3. Excellent sound insulation performance, reducing noise by 3-5Db.

8. What are the methods for purchasing aluminum alloy window with broken bridge?

depending on the materials: thickness, strength and oxide film, etc., should comply with the relevant national standards, the wall thickness should be above 1.4 mm, the tensile strength should reach 157 newtons per square millimeter, the yield strength should reach 18 newtons per square millimeter, and the oxide film thickness should reach 1 microns.

Price of broken bridge aluminum alloy window

The price is hard to say. The market is uneven, so it is difficult to tell you the price, but it ranges from several hundred to several thousand. There are all doors and windows of one square meter. It depends on what kind of doors and windows you want to choose. If the price is different, the quality will be different. If you don't like me, you should choose aluminum doors and windows with broken bridges, as well as glass and locks. However, if you want to buy good quality, it is better to estimate that the price is 15 yuan | square meter.

Which is better, plastic steel window or aluminum alloy window

1. Wind pressure strength and water tightness? The wind pressure resistance and water tightness of plastic-steel windows fully meet the general requirements. Have you noticed that aluminum alloy doors and windows are often the ones with high probability of water leakage in the market, while plastic-steel doors and windows have better water tightness because of their strong integrity.

2. air tightness:? The air tightness of plastic-steel windows (especially the air tightness of flat plastic windows is higher) is definitely better than that of aluminum alloy windows of the same grade, and people who have used them have their own experience.

3. Thermal insulation performance: the thermal insulation performance of aluminum windows of the same grade is not as good as that of plastic-steel windows (this is certain and recognized). The heat transfer coefficient K of plastic-steel casement windows with 5+9+5 insulating glass can reach 2.5, which is higher than the requirements of national energy-saving doors and windows; Can aluminum alloy windows of the same grade (same price) be done? The price is almost doubled.

4. Daylighting performance:? Because the cross section of plastic steel window is larger than that of aluminum alloy, the lighting performance of plastic steel window is slightly worse than that of aluminum window, but the openings of windows are much larger than before, which does not affect indoor lighting on the whole.

5. Sound insulation performance:? The gap sealing level of aluminum window and plastic steel window is basically the same, and their sound insulation performance is also basically the same. (This sentence is absolutely wrong. Is the sound insulation performance only determined by the gap? The material is the primary factor that determines its sound insulation performance. Everyone knows that the sound insulation performance of plastic steel windows at the same price is much better than that of aluminum alloy windows.)

6. Fire resistance? The fireproof performance of flame-retardant PVC plastic steel window is better than that of combustible wood window, but it is worse than that of non-combustible aluminum alloy window. (Plastic-steel window is an ideal choice because it is an excellent fire-extinguishing material, does not spontaneously ignite, does not support combustion, and can extinguish itself)

7. Lightning protection and electrostatic problems: Aluminum alloy is a good conductor, so it can be used as lightning protection facilities and prevent static electricity when it is used as building external protection structure. ? (Plastic-steel windows are insulators, so they are safer than aluminum alloy windows which are easy to conduct electricity)

8. Decorative:? As the exterior windows of buildings, plastic steel windows can only be mainly white, which can not meet the needs of colorful exterior wall decoration of various buildings. ? (color plastic-steel windows such as double-color * * * extrusion and film covering are everywhere in the market, and the color change is no less than that of aluminum alloy)

9. Aging problem:? PVC plastic profiles will age, and the macromolecular chains of polymer PVC resin will break under the action of ultraviolet rays, which will make the surface of the material lose luster, change color and powder, and the mechanical properties of the profiles will decrease. And aluminum alloy has the function of anti-aging. The plastic-steel windows abroad 5 years ago are still very good, but the impression of plastic-steel windows in China is only blinded by fake and shoddy products; The corrosion resistance of inferior aluminum alloy windows is very poor)

1. Deformation and expansion problems:? Plastic steel windows are easily deformed by heat, brittle when cold, and have poor dimensional and shape stability. It is often necessary to use the rigidity of glass to prevent the deformation of window frames. Aluminum alloy has the advantages of high temperature resistance and difficult deformation. (The deformation of plastic-steel windows is worse than that of aluminum windows, but there is no problem within the size control range.)

Size specifications of aluminum alloy windows

Doors and windows made of aluminum alloy extruded profiles as frames, stiles and fans are called aluminum alloy doors and windows, which are referred to as aluminum doors and windows for short. Including aluminum alloy as the stress member (the member that bears and transmits self-weight and load) and wood and plastic composite doors and windows, which are called aluminum-wood composite doors and windows for short.

there are five kinds of aluminum alloy doors and windows: push-pull aluminum alloy doors, push-pull aluminum alloy windows, flat aluminum alloy doors, flat aluminum alloy windows and aluminum alloy ground spring doors.

a kind of door and window is divided into basic door and window and combined door and window. Basic doors and windows are composed of frames, fans, glass, hardware fittings and sealing materials. Combined doors and windows are composed of more than two basic doors and windows, which are assembled into other forms of windows or window-connecting doors.

according to the opening mode, it can be divided into: fixed window, upper hanging window, middle hanging window, lower hanging window, vertical rotating window, casement window, pulley casement window, casement lower hanging window, sliding window, sliding casement window, folding door and floor spring door. ? According to the performance, it is divided into: ordinary doors and windows, sound insulation doors and windows, and thermal insulation doors and windows. ? According to the application parts, it is divided into: internal doors and windows, external doors and windows.

each kind of door and window is divided into several series according to the structural dimension of the door and window frame thickness. for example, a push-pull aluminum alloy door with the structural dimension of the door frame thickness of 9mm is called a 9-series push-pull aluminum alloy door. 5.6.7.8 These are the widths of profiles in millimeters. 5.6 is usually casement windows, 73,8,85,9 are mostly sliding windows

There are 7 series and 9 series aluminum alloy sliding doors, and the basic door opening heights are 21, 24, 27,? 3mm, the basic width of the door opening is 15, 18, 21, 27, 3, 33 and 36 mm. There are 55 series, 6 series, 7 series, 9 series and 9-I series for sliding aluminum alloy windows. The basic window heights are 9, 12, 14, 15, 18 and 21mm; The basic window width is 12, 15,? 18、21、24、27、3mm。

there are 5 series, 55 series and 7 series of aluminum alloy horizontal doors. The basic door height is 21, 24,? 27mm, the basic width of the doorway is 8, 9, 12, 15 and 18 mm. There are 4 series, 5 series and 7 series of flat aluminum alloy windows. The basic window height is 6,? 9、12、14、15、18、21mm; The basic window widths are 6, 9, 12, 15, 18 and 21mm.

There are 7 series and 1 series aluminum alloy floor spring doors. The height of the basic doorway is 21, 24, 27, 3 and 33mm, and the width of the basic doorway is 9, 1, 15, 18, 24, 3, 33 and 36mm.

The colors of anodic oxide film on the surface of aluminum alloy profiles are silvery white and bronze. According to the processing technology of profile after extrusion, it can be basically divided into oxidation, electrophoresis, electrostatic powder spraying and fluorocarbon spraying, that is to say, the coating methods are different. At present, 85% of the consumption in the market is electrostatic powder spraying profiles, that is, colored aluminum profiles.

glass varieties can be ordinary flat glass, float glass, laminated glass, tempered glass, insulating glass, etc. Generally, the thickness of glass is 5mm or 6mm.
