Doors and windows are important materials for home decoration. With the development of science and technology, the function and aesthetics gradually improve. So far, the most commonly used materials for doors and windows are aluminum alloy doors and windows. In this article, we will introduce you to the types of aluminum alloy door and window profiles, and introduce you to aluminum alloy doors and windows through the opening method, glass and hardware.
1.Classification of aluminum alloy window profiles
According to its profile characteristics, aluminum alloy can be divided into ordinary aluminum alloy and broken bridge aluminum alloy. The main difference is: ordinary aluminum profile: the profile is one piece, no broken line in the middle, heat transfer, heat dissipation faster;
Broken bridge aluminum profile: the whole profile, the middle and PA66 nylon strip connection (whether there is such a nylon strip is to distinguish between ordinary aluminum and broken bridge aluminum mark), and connected to form three layers of air. Internal and external non-conductive, the temperature difference between internal and external is different, good sound insulation and thermal insulation properties.
2.Aluminum alloy window opening method
(1) Aluminum windows can be divided into three categories according to their functional use: sliding windows, casement windows and top-hung windows. Sliding window: There are two types of sliding windows, left, right and up and down.
(2) Choose the appropriate sliding method according to the proportion of window size.
a.Advantages: simplicity, wide window, large glass block, wide field of view, in-plane opening, less space occupied and easy screen installation.
b.Disadvantages: these two windows can not be opened at the same time, at most only half. Ventilation is relatively poor, sometimes slightly less airtight.
c. Casement window: separate outward opening and inward opening, inward opening type is easy to clean, and outward opening type does not occupy space when opening.
(3) Choose the appropriate opening method according to the actual use.
a. Advantages: large openable area, good ventilation, excellent sealing and impermeability.
b.Disadvantages: Small window width, not a wide view. The opening window outside the wall occupies the space outside the wall and is easily damaged when strong winds blow. And the open window occupies part of the interior space. It is inconvenient to use the screen and it is not easy to use the screen and curtains when the window is open. In fact, the percentage of consumers who choose to use sliding windows is greater than the percentage of consumers who use casement windows.
c.Top-hung windows: developed on the basis of casement windows, they are characterized by the fact that they can be opened horizontally and pushed open from the top. It can be made to open inward, inverted inward, open outward and inverted, etc. It not only allows ventilation, but also ensures security. Thanks to the hinges, the window can only be opened with a gap of ten centimeters and cannot be reached from the outside. It is especially suitable for the situation when there is no one at home.
3. Aluminum window glass
It is recommended to use double-layer insulating tempered glass in aluminum windows. Its sound insulation, heat insulation and safety performance is far better than ordinary glass. Usually in the industry, the glass is expressed as: 5mm 12A 5mm, 8mm 15A 8mm, etc. The first and third numbers indicate tempered glass. The first and third numbers indicate the thickness of tempered glass, i.e., 5mm or 8mm thick tempered glass, while 12A or 15A indicates the distance between two layers of tempered glass (the distance between hollow sections), i.e., 12mm or 15mm. spacing. In general, the greater the distance between the center sections, the better the performance. Due to the characteristics of the profile, for example, choose for windows with a large distance of the hollow section, only broken aluminum alloy can be used.
4. Aluminum alloy window hardware
Aluminum alloy window hardware is also important, mainly used for casement windows. Typically, aluminum window hardware includes handles, toggles, links, sliding brackets, hinges, locking blocks and limit brackets. Since there are more profiles and hardware used for opening windows, the price of opening windows is higher than that of sliding windows in the same situation.
5. What are system windows and doors?
In recent years, the concept of system windows and doors has emerged as consumers' demands for quality of life have increased. So what are system windows and doors? First, we must understand a misunderstanding. In the initial consumer ideology, high-quality windows and doors are equivalent to high-performance windows and doors.
In fact, high-quality windows and doors ≠ high-performance windows and doors. High-quality windows and doors only indicate that the obvious parts of the window or door (e.g., aluminum, glass, and fittings) are of good quality. High-performance windows and doors pay more attention to the professional performance and multifunctionality of the product on this basis. So-called system windows and doors are essentially a perfect organic combination of performance systems. Comprehensive consideration of a series of physical properties such as watertightness, airtightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weather resistance and operating sense. And the performance of equipment, profiles, fittings, glass, glue adhesive and seals of each link will eventually form a high-performance system doors and windows.
The top-hung windows mentioned above are the embodiment of system doors and windows. Moreover, there is no doubt that the profiles of system doors and windows are all aluminum alloy profiles with broken bridges.
