How to choose aluminum doors and windows
Doors and windows are essential materials for home decoration. With the development of science and technology, their functionality and aesthetics are gradually improved. Up to now, aluminum alloy doors and windows are still the most widely used door and window materials. This article introduces the types, opening methods, glass, hardware and other aspects of aluminum doors and windows to let you know about them.
▌Aluminum windows- classification
According to the characteristics of their profiles, aluminum alloys can be divided into ordinary aluminum alloys and broken bridge aluminum alloys. The main differences are:
Ordinary aluminum profiles: The profiles are integral, without breaks in the middle, and heat transfer and heat dissipation are relatively fast;
Broken bridge aluminum profiles: The profiles are integral, connected in the middle with PA66 nylon strips (whether there are such nylon strips is a sign to distinguish between ordinary aluminum and broken bridge aluminum), forming three layers of air layers, which are non-conductors inside and outside, and have different temperature differences inside and outside, and have better sound insulation and heat insulation performance.
The cross-section comparison is shown in the figure below, and the difference between the two can be seen intuitively.
▌Aluminum windows – opening methods
Aluminum windows can be divided into three categories according to their functional usage: sliding windows, casement windows, and top-hung windows.
Sliding windows: There are two types of sliding windows: left and right, and up and down. Choose the appropriate sliding method according to the size ratio of the window.
Casement windows: divided into outward opening and inward opening, the inward opening type is convenient for window cleaning, and the outward opening type does not take up space when opened. Choose the appropriate opening method according to the actual use.
Top-hung windows: developed on the basis of opening windows, its characteristics are that it can be opened horizontally and pushed open from the top. It can be made into an inward-opening and inward-tilting, an outward-opening and outward-tilting, etc. It can be ventilated and safe. Because of the hinges, the window can only be opened ten centimeters, and hands cannot be put in from the outside, which is especially suitable for use when no one is at home.
▌Aluminum Windows – Glass
It is recommended to use double-layer hollow tempered glass for aluminum alloy windows. Its sound insulation, heat insulation and safety performance are far superior to ordinary glass.
Usually in the industry, the way to express glass is: 5mm+12A+5mm, 8mm+15A+8mm, etc.
The first and third numbers represent the thickness of the tempered glass, that is, 5mm or 8mm thick tempered glass, and 12A or 15A represents the distance between the two layers of tempered glass (the distance of the hollow), that is, 12mm or 15mm. Generally speaking, the larger the hollow distance, the better the performance. Because of the characteristics of the profile, if you choose a window with a larger hollow distance, you can only choose a broken bridge aluminum alloy.
▌Aluminum Windows – Hardware
The hardware of aluminum alloy windows is also very important, mainly for casement windows. Usually the hardware accessories of aluminum alloy windows include handles, forks, connecting rods, sliding supports, hinges, lock blocks, limit supports, etc.
Because the number of profiles and hardware used in window openings is more, under the same circumstances, the price of window openings is higher than that of sliding windows. Regarding the selection of hardware, for window openings, imported brands can use Camel, domestic brands can use Aobo, and sliding windows can use Chunguang. In comparison, window openings have higher requirements for hardware.
