The main reasons for determining the price of broken aluminium alloy doors and windows are the following: aluminium broken windows typically choose middle steel glass (some of the high-end brands already use car-grade steel glass, more flattening, and better light). But now, for the sake of common appearance, the balconies will be consolidated by the building department, requiring owners to use the same materials and colours as the windows of the entire building when closing the balconies. The type of window opening in the northern city suggests that the window should be flat because the largest function of broken aluminium is temperature protection, energy conservation, wind pressure resistance, soundproofing, and push-and-pull doors and windows significantly reduce sealing performance。
Many owners will choose to clean up the balcony as soon as it closes. Packaging seals are protected from external weather, are safer, quieter and increase the availability of space。
New neighbours often ask each other about their choice of brand and price. If they only told the price, the answer would have no reference value. If you go to the door and window store and ask how much it costs, all who can answer your price are gangsters
Although the article cannot tell you the answer directly, it clearly tells you the determinants of the price of broken aluminium. On the basis of these price comparisons, merchants will never make you new and will never be “killed”。
The price of broken aluminium alloy doors and windows was determined for five main reasons:
Detailed explanations are given for the type, glass, hardware, format, etc. It's a little long, but the last reminder is important. Read it carefully
I. Models
Aluminium model
Breakout aluminium is generally classified into brands and models. High-end broken-bridge aluminium in many areas, including 1050, 6063, 6063a, 6463, 6060, 6106, 6005, 6005a, 6061, 6082, 6262, 6351, is mostly used for 6063-t5 and 6063-t6 aluminium。
The difference is not obvious, and the main difference is in mechanics. In terms of strength and stress, t6 aluminum alloys are slightly better than t5 aluminum alloys。
There are two main points in identifying good and bad profiles:
Look at the look. High-quality materials of equal size, sound cavity structure, soft colour, protective membrane flat-free bubbles。
Look at the code. The real face has a security code and consists of 20 numeric arab dots. The numbers are clear and not easy to erase. The coded number of poor-quality materials is vague and easily erased。
2. Type width and type wall thickness
When selecting windows, you may often hear figures like 60, 65, 79, 110, 120, which refer to the width of the window frame。
60 indicates 60 mm width for window frames with heat insulation and 65 mm for such push, as detailed in the figure below
Note that the width of the insulation can affect the overall width, for example, in general 60 and 65, but the insulation is broader. It needs to be noted that the larger the model, the better。
The minimum measured wall thickness of the parent cross-section of the main subject matter of the wall thickness of the type shall be no less than 1. 4 mm. The increase in wall thickness increases resilience and resistance to wind pressure levels. With the exception of special areas, generally 1. 4 mm meets safety standards, but the domestic clothing market is currently dominated by 1. 6 mm wall thickness。
Ii. Glass
Most of the high-end windows in the market now use the low-e film. If the merchant cannot make the low-e film, try not to coat it. Other coatings have a significant impact on light. Among them, the glass amplifiers are special and can be seen from inside, but not from outside, and are also resistant to ultraviolet light, requiring additional payment。
The glass is generally empty (a number of high-end brands already use car-grade steel glass, with a higher level of flatness and better light). Steeled glass (all with cc markers) has a high hardness. When broken, the glass becomes granule-like, linked and unharmed (the best steel glass also has a self-explosion rate of three per 1,000)。
When asked about glass structures, businesses usually answer this, for example, with two layers of 5 mm+15 mma+5 mm, where a represents the middle air layer and others represents the thickness of the glass。
The thicker the general glass thickness and the middle air layer (filled americium), the better the safety, soundproofness, air intensities, of course the most expensive. In order to achieve a temperature-preservation effect, at least two layers of mid-altitude 12 mm thickness and above (personal recommendation 12-15 is sufficient) are selected, two layers of steeled glass are selected, with two faces of glass at least 4-5 mm thick。
The maximum area used is 2 square metres for 5 mm thick, 3 square metres for 6 mm thick and 4 square metres for 8 mm thick. The maximum use area of the glass layer is 7 m2. For reasons of safety, it is recommended to use laminate glass when glass is too big。
Fill inside the glass and fill with argon gas better than air. The process of intra-glass aluminium partitions is divided into bends and plugs, which are more condensed than plugs。
Iii. Hardware
Select hardware to look at the brand, and then look at the way it is opened。
Good brands, whether domestic or imported. The average domestic output is around $300 and imports over $600. If the price is too low, beware of counterfeit products. There are many counterfeit hardware products that ordinary owners cannot identify。
Whether it is open either internally or internally (recommended) or externally, or whether it is open or out, directly affects prices。
The authenticity of conventional hardware can be checked. Sigiriya, for example, has a hard-copy code and a batch seal that allows it to view the specific production process. The windows and windows used are good german imports of gold, sgilia, etc。
Iv. Format
For example, a window of 2 m*2m, open in two, varies widely。
However, the balcony is now packed and, in order to unify its appearance, it is generally fixed by the building sector. Owners are required to use the same materials, in the same colour, as the windows of the entire building when closing the balcony. Before packing, please request a standard form for accommodation, and do not cause loss due to negligence。
The type of window opening in the northern city suggests flat window opening, because the most important effect of broken aluminium is temperature protection, energy conservation, wind resistance, soundproofing, and the sealing of push-through windows is significantly reduced.
V. Other
It looks simple, but it's the most complex item in the paper. I don't want to write anymore
1. Use of seals: quality composites superior to single epdm
2. Use of adhesive seals: the choice must be made of the major brands of the importing country
3. Insulation: opting for nylon pa66
4. Screen window: it is recommended to select a diamond-shaped net lock
5. Other possible additions:
Special custom colours
Special appearances, such as narrow borders
(b) installation costs (whether higher-level costs will be increased)
(b) the cost of glue (position of glue, brand of glue)
Whether the minimum size is charged (generally less than 1 square metre at 1 square metre)
(b) whether bathroom windows have built-in blinds
Costs of removal of old windows (aluminium alloy doors and windows may be agreed in advance, the price recovered from the old windows)
If all three are closed to the aluminium alloy doors and windows, the price of the pillar increases over one side
After the sale (a number of high-end brands also clean glass free of charge every year), the glass is fixed for several years and the explosion is guaranteed。
A sweet hint
Following the installation of the window, please remove the protective film covering its surface within 60 days. The protective film on the window frames was designed to prevent minor scratches on the surface of the material during the construction of other works during the renovation process。
When windows are installed and if protective film is not removed in a timely manner, the windows are tanned several times under the sun, the pattern and text of the protective film are stamped on the surface of the window frame so that the smooth surface of the original shape is no longer cleaned. When it is torn again, some plastic prints appear on the surface of the material。
