Aluminum casement windows are windows with frame and fan structure made of aluminum alloy building profiles. They are divided into ordinary aluminum casement windows and broken bridge aluminum casement windows. Aluminum casement windows are beautiful, sealed and strong, and are widely used in the field of construction engineering. In home decoration, the sash frame is large and can be inlaid with a larger area of glass, so that indoor light is sufficient and bright, and the facade between indoor and outdoor is enhanced The contrast between virtual and real makes the room more layered. Aluminum alloy itself is easy to squeeze, the cross-sectional dimension of the profile is accurate, and the processing accuracy is high. Therefore, many owners choose to use aluminum alloy casement windows in the decoration.
At the end of the 1980s, doors and windows were aluminum alloy windows made of aluminum alloy profiles. Although some of the shortcomings of steel windows were solved, the profiles themselves were metal materials, which had fast heat and cold conduction. The whole window of steel windows and aluminum alloy windows, which K values are all above 6.0w/(m2.K), which does not fundamentally solve the problems of sealing and heat preservation. Although it can be equipped with insulating glass, the K value of the whole window can only reach about 4.5w/(m2.K). Broken bridge aluminum alloy heat-insulating doors and windows appeared in the door and window market in the middle and late 1990s, which were high-end doors and windows products in the door and window market at that time. The profile design adopts high-strength insulating and heat-insulating synthetic materials, and the surface treatment adopts high-tech such as powder spraying, fluorocarbon spraying and resin hot stamping. It can meet the ever-changing color matching needs. The outstanding advantages of broken bridge aluminum alloy thermal insulation doors and windows are light weight, high strength, good water and air tightness, good fire resistance, large lighting surface, atmospheric corrosion resistance, long service life, good decorative effect, and good environmental performance. However, with the improvement of people's quality of life, more and more attention is paid to health, environmental protection and energy saving. Heat-insulating aluminum alloy windows and plastic-steel windows cannot match the interior decoration, can not satisfy the appreciation of modern people, and are not in line with the national energy-saving climate.
The aluminum alloy market has huge business opportunities, especially aluminum alloy doors and windows are favored in cities and towns. In my country’s building door and window product market, aluminum doors and windows account for the largest proportion, accounting for 55%; followed by plastic doors and windows, accounting for 35%; steel doors and windows products account for 6%; products made of other materials account for the remaining 4%. Although the quality of aluminum alloy products has been questioned by ordinary people for a certain period of time or in certain areas, due to the limited living standards of the domestic people and the constraints of economic conditions, aluminum doors and windows are still their first choice for a considerable number of consumers.
The advantage of ordinary aluminum alloy windows is that they have better weather resistance and aging resistance. (Disadvantages) The heat insulation is not as good as other materials, and the colors are only white and tea. The advantages of plastic steel windows are good sound insulation, heat insulation, fire resistance, air tightness, water tightness, anti-corrosion, and heat preservation. (Disadvantages) After all, it is a PVC plastic profile. After a long time, the surface will turn yellow and the window will be deformed. The service life is 20-30 years. The advantage of broken bridge aluminum doors and windows is that the aluminum material is 1.4mm or more, and the heat insulation layer is added to all the foundations; it also has good sound insulation, heat insulation, fire resistance, air tightness, water tightness, corrosion resistance, Thermal insulation, maintenance-free, etc.; it is a metal aluminum profile that can be used for a long time without changing its shape and color. (Disadvantages) The price of aluminum is expensive and the production cost is relatively high.
The advantages of aluminum alloy casement windows are large opening area, good ventilation, good airtightness, sound insulation, heat preservation, and impermeability. Aluminum alloy casement windows are divided into inner casement windows and outer casement windows. The advantage of the inward opening window is that it is convenient to clean the window. The disadvantage is that the window width is small, the field of view is not wide, and it takes up part of the indoor space when opened. It is inconvenient to use the screen window. If the sealing quality is not closed, the rain may leak. The advantage of outward-opening windows is that they do not take up space when opened, but the disadvantage is that they take up space outside the wall when opened, and are easily damaged in strong wind. In cold areas or rooms with special requirements, double-layer aluminum alloy casement windows are also used. There are different opening methods for aluminum double-layer casement windows. Commonly used methods include inner opening, outer opening and double opening.
The hinge is installed on one side of the window sash and connected to the window frame. According to the outward or inward opening, this type of window is divided into an outer casement window and an inner casement window. The characteristics of this type of window are: simple structure, flexible opening, easy to clean, and good sealing performance when closed. It is the most widely used window type in civil buildings.
Aluminum casement windows are better than sliding windows in performance, but sliding windows are better than casement windows in terms of processing and operation. Because of this reason, casement windows are widely used in urban commercial and residential buildings, office buildings, high-end residential buildings, villas and other medium and high-end buildings; while sliding windows are widely used in industrial plants, rural residences and other medium and low-end buildings. Aluminum alloy doors and windows are classified in terms of their opening methods. The more popular and practical window types on the market are sliding windows and casement windows. Casement windows refer to doors and windows whose hinges (hinge) are installed on the sides of doors and windows to open inward or outward; sliding doors and windows mainly refer to doors and windows whose sashes are vertically sliding left and right in the horizontal direction. Sliding and casement are compared with the same glass and accessories.
In appearance, the difference between casement windows and sliding windows is mainly in the combination with the overall style of the building. Because of the flexibility of the division of the casement window, it can be made into any line of facade effect, and it is very important for Oita. For floor-to-ceiling windows, the opening fan only occupies a small part of the whole window, so it is more suitable for high-end real estate with strict requirements on the overall effect of the building, especially in line with the large-scale, spacious, bright, and transparent effect pursued by architects. Good, harmonious and smooth building. Sliding windows can only be pulled horizontally because they can only be opened horizontally, so they are difficult to match with the fixed glass of large divisions. They are generally more suitable for open factories or rural home buildings with clear horizontal and vertical lines.
In terms of the three performances of doors and windows (wind pressure resistance, water tightness, and air tightness), casement windows are generally better than sliding windows. The wind pressure resistance of doors and windows depends on the resistance moment of the main force-bearing members of the doors and windows. The larger the section of the profile, the larger the resistance moment, but it is not completely proportional. Casement windows generally have small cross-sections, but their main force-bearing members are usually made of assembling materials or vertical materials. These main force-bearing members will be strengthened accordingly during the design process, so their wind pressure resistance performance is better . The cross section of the sliding window profile is generally larger, and it stands to reason that its wind pressure resistance performance should be better, but only a little in-depth force analysis will show that the main force member is often the middle fan material, and its upper and lower stiles only rely on pulleys To withstand the horizontal wind load, the wind pressure resistance performance is generally not ideal. The water tightness of doors and windows depends on the sealing effect of the opening part, and casement windows are generally sealed with rubber strips. In terms of air tightness, two-point locks or heaven and earth locks are used to lock and seal the opening fans of casement windows on the market. Therefore, casement windows are generally better than sliding windows in three aspects. This is why most high-end commercial and residential buildings choose to use casement windows.
In terms of thermal insulation performance, casement windows on the market generally use sealing tapes for sealing, while sliding windows generally use tops for sealing. The sealing effect of rubber strips is generally better than tops sealing. Two-point locks or sky-earth locks are used to lock and seal the opening fan of the casement window, and the sealing effect is better. The sliding windows are generally locked by hook locks or latch locks, and the sealing effect is not ideal.
Doors and windows are the openings of the building envelope. They are extremely important functional components that resist wind, rain, dust and insects, and realize the physical properties of the building's heat, sound, and light environment. They are directly related to the safety of the building, comfort and energy saving, and people's living standards. Improvement. Therefore, the choice of doors and windows in the purchase of decoration materials is very worthy of attention.
What are thermal-break aluminum doors and windows? Thermal-break aluminum doors and windows refer to doors and windows made of materials such as thermally insulated broken bridge aluminum profiles and insulating glass after some processes, which have the functions of energy saving, sound insulation, noise prevention, dustproof, and waterproof. The thermal conductivity K value of broken aluminum doors and windows is less than 3W/㎡·K, which is half of the heat loss of ordinary doors and windows, reduces heating costs by about 30%, and has a sound insulation of more than 29 decibels. It has good water and air tightness, and both reach the national level. A1 window standard. Advantages: large opening area, good ventilation, good sealing, excellent sound insulation, heat preservation, and impermeability. The inward opening type is convenient for cleaning windows; the outward opening type does not take up space when opening. Disadvantages: the window width is small and the field of view is not wide. Opening windows outside the wall takes up a space outside the wall and is easily damaged when strong winds blow; and windows opening inside takes up part of the indoor space. It is inconvenient to use screens, and it is inconvenient to use screens and curtains when opening windows. , If the quality installation fails, rain may leak. The use of thermally insulated aluminum alloy<aluminum alloy profile, its thermal conductivity coefficient is 1.8～3.5W/㎡·k, which is much lower than the ordinary aluminum alloy profile 140～170W/㎡·k; the hollow glass structure is adopted, and its thermal conductivity coefficient is 2.0～ 3.59W/m2·k is much lower than ordinary aluminum alloy profiles 6.69～6.84W/㎡·k. Broken bridge aluminum doors and windows effectively reduce the heat conduction through doors and windows. Therefore, young people nowadays are becoming more and more ignorant of broken bridge casement windows. I believe that the future development of broken bridge casement doors should not be underestimated. Choose good quality doors and windows, please choose Guangyuan Aluminum Windows and Doors.
