Broken Bridge Aluminum Doors and Windows 100 Frequently Cheated


Among the large hard-mounted pieces, the broken bridge aluminum window is the deepest one, for the following reasons

1. The price is expensive, just do it casually, it will cost tens of thousands.

2. If there are many additional items, more than 1,000 can be typed with glue.

3. The brands are mixed, and there are too many small workshops in small factories, so you can't rest assured even if you spend money.

4. The quality is uneven. All kinds of recycled aluminum and inferior aluminum are flooding the market.

5. The "South Phoenix aluminum North Zhongwang" that everyone has heard is only the brand of aluminum manufacturers, not the brand of windows.

6. At present, there is no window brand with absolute market discourse right. Choosing a window is not just a brand. Generally, window brand merchants mainly focus on profiles, others such as glass, accessories, hardware, measurement, processing, installation will ultimately determine the effect.

7. The angle codes of regular door and window manufacturers are all made of aluminum profiles with a wall thickness of not less than 3mm. There are swarthy merchants aluminum profiles replaced with plastic ones. The appearance is very ugly, and only a little can be seen from the gap.

Window selection, hardware accessories, measurement, cost, installation

1. Most people's balcony walls are not completely horizontal/vertical. The same plane needs to be measured in multiple places to avoid large gaps/cups that cannot be installed.

2. Measuring windows is not only the accurate size, but also the common measurement results, calculation methods, whether there is any loss, etc. If there are more small windows in the House, the loss will be very large.

3. The measurement should be done early, and the measurement should be done during the demolition period, because the production cycle of broken bridge windows is generally 12-15 days.

4. Before measuring, try to go to the factory if necessary. Look at the sample workmanship on site. Focus on the formation and clearance of the 45-degree angle, the size of the gap in the middle beam link and whether to inject the angle glue.

5. The payment mode is basically that after the designer measures the size, a part of the deposit will be given after the scheme is signed, and the final payment will be given after installation or acceptance.

The installation is not good, no matter how expensive the window is, it is white and blind

You should pay attention to the crafting details of windows.

Some friends used German xuge, and the materials were imported, but the installer was very unreliable. He was outsourced to a small contractor. Later, the window leaked water, and the glass bead quality was very poor, and there were many problems. I bought such expensive windows for nothing.

The following are the installation details summarized by some owners who have been decorated.

1. Generally, it takes a whole day to install the Windows. The installation of the windows is an aerial work. Workers must be forced to wear safety belts, otherwise the owner of the accident will never take off the responsibility.

2. When installing, the window should be as close as possible, and it should not exceed the waterproof edge, so that the window sill can be wider.

3. It is better to stare at it all the way, don't pretend to be slanted, rework is more difficult.

4. Glue is also very important. Styrofoam should be beaten enough without leaving any gaps. The sealant should be neat, and it cannot be wiped out in a mess, otherwise it will be ugly.

5. If the outside is close to protective grating, car window shade installation position must be reserved. I have seen a car window shade one that cannot be installed, resulting in rework.

6. Install the windows as far as possible before the tiles are pasted, before the tiles leave the site, because some windowsills need the tiles to be leveled and closed.

7. Just install the window and try to avoid the construction and cleaning of dust. It will be covered with dust only after waterproof adhesive and 12 hours.

8. Install all window frames first, then install all windows. If you want to install guardrails, you must do so after installing windows.

9. After the decoration is completed, the installation time is about car window shade. Generally, merchants will install car window shade windows on the same day, and later decoration will often stain car window shade. Separate installation ensures that car window shade will not be stained by the construction process. If you find that the window has details that need to be fine-tuned, you can also solve it when the second door-to-door installation is car window shade.

What are the common misunderstandings about window profiles?

1. Window brands generally focus on profiles, others such as glass and hardware may not be the best, and hardware generally requires brands.

2. Window selection brands are more profile selection, glass, hardware and other brands have separate brands, such as float glass and Noto hardware.

3. Broken Bridge aluminum model 55, 60, 65, 70, refers to the window frame thickness, 55 is 55mm,60 is 60mm,65 is 65mm,70 is 70mm.

4. The heat insulation strip is nylon (PA66), which is resistant to 300℃ high temperature. Counterfeit products are generally replaced by flammable PVC materials and can be identified by lighters.

5. Generally speaking, the wall thickness of the national standard must be greater than or equal to 1.4mm, and less than 1.4 is inferior. Take 70 as an example, the wall thickness is 1.4mm, 1.6mm and 1.8mm.

6. Broken Bridge aluminum genuine goods feels very smooth. There are many impurities in the fake broken bridge aluminum, and the extruded lines are obvious. Aluminum waste will be very rough.

Under what circumstances do you choose what kind of window glass?

8. Tempered glass has good safety. If the glass is broken, it will become granular and will not hurt people. Insulating glass has good sound insulation and heat preservation effect.

9. Now all tempered glass has CCC logo. In the corner below the window, generally tempered glass needs to be charged extra.

10. If it is a high-rise, floor-to-ceiling window, or the width of single-sided glass exceeds 3 ㎡, it is recommended to use tempered glass on the innermost side.

11. For safety, try to temper windows larger than 1.5 ㎡.

12. If hollow glass is selected, in order to achieve the heat preservation effect, the hollow thickness of 12mm or more is generally selected, and the glass on both sides should reach the thickness of 4~5mm.

13. Double-layer recommend mm 12mmA 5mm, three-layer recommend mm 6mmA 5mm 6mmA 5mm, where A indicates the degree of intermediate air layer and others represent the thickness of glass. (The specific choice of hollow glass is determined by the profile series and the intermediate interval of the profile)

14. After the glass is coated, you can see the outside from the inside, and you can't see the inside from the outside. It is also UV-proof and requires extra money.

15. If the merchant cannot make low-e film, try not to apply the film. Other coating will affect the indoor light.

What are the details of window accessories that are easy for everyone to ignore?

16. Recommend use diamond Net car window shade, anti-theft anti-mosquito anti-fall, safety first. While choosing invisible car window shade, watching with damper or not can avoid car window shade noise.

17. Some merchants include waterproof adhesive of the fee, while others do not. Try to include waterproof adhesive, because the usage will be large.

18. Don't apply a little window edge to the waterproof adhesive outside the window for the sake of beauty. It is better to apply more, not afraid of water seepage from the wall.

19. Sealing strip is a very inconspicuous auxiliary material, but the quality will seriously affect the window sealing degree, and the effect of different quality is very different.

20.7 seals and 10 seals are not as good as better sealing strips. Choose tough and elastic, do not choose particularly hard, especially in northern weather, can not be used, recommend EPDM or floating on water.

21. The installation of Windows needs to be fixed with glue. Styrofoam silicon sealant is indispensable. The choice is not good, and the possibility of air leakage and rain leakage will be very high in the future.

22. A large amount of glue will be used in the installation. It is better to calculate it into the cost per square meter, negotiate with the merchant to use the brand and sign the contract.

23. Styrofoam long time easy to break, leaking, outside the window Styrofoam dry, cut off the excess part with wallpaper knife, and then seal it with silicon sealant.

24. In order to save costs, some merchants will choose acid glue. We should try our best to choose environmentally friendly neutral glue. After installing the window, there is no odor.

25. Waterproof adhesive some merchants only quote the price of single-sided gluing, which gives you a very cheap feeling, but it needs double-sided construction.

26. When the windows are large and several are connected, you must fix them with columns.

27. The column is also called mid-stand, mid-stand column, and reinforced column. Most merchants like to collect fees separately, and some merchants are free of charge.

28. If the height of the window exceeds a certain height, the load-bearing beam needs to be installed, which is actually a horizontal column. Because the material used is large, it is usually charged alone.

29. When the window produces a 90-degree corner, use the corner to connect the pillars of the two window frames. Corner is also called corner column. Windows without turning and Radian do not need to be installed, for example, one-shaped windows will not be used.

30. Angle code is an essential hardware for broken bridge aluminum doors and windows. Its biggest function is to reinforce broken bridge aluminum doors and windows, making it difficult to deform. Its firmness, safety and strong wind resistance are greatly enhanced.

31. Two corner codes and one corner piece are needed for one corner. In order to ensure the sealing of doors and windows, the corner codes also need to be used with corner glue to achieve the absolute sealing effect. Some merchants will charge separately.

32. The angle codes of regular door and window manufacturers are all made of aluminum profiles with a wall thickness of not less than 3mm. Some replace aluminum profiles with plastic ones. The appearance is hard to see, and only a little can be seen from the gap.

33. Attached frame, also called auxiliary frame and protective frame, is usually fixed in the wall when it is added around the window. If the auxiliary frame is not handled well, leakage will easily occur, non-essential.

34. Several situations that need to be framed: if the window needs to be covered with window frame (also called window opening), tiles need to be pasted next to it, and ceiling is needed on the top, then the attached frame needs to be added; If the window opening is uneven, if you cannot accept the seam retention treatment, it is recommended to add the protective frame; Some old community wall skins are shoveled to red bricks, and it is recommended to add the protective frame at the window hinge position, which will not cause the gray window to not open.

35. The above are all window accessories, which are generally not included in the window when they are not all covered.

The following is hardware. If it is not fully covered, no charge depends on the merchant.

36. Hardware directly affects the opening flexibility, tightness and service life of doors and windows, including handle (handle), actuator, hinge, wind brace, upturning support, flat opening support, lock, locator, etc, it is better to choose imported or domestic famous brands.

37. The window hardware of different opening methods is different. The hardware of casement window mainly consists of handles, actuators, hinges, locking points and wind brace.

38. Sliding window hardware mainly includes crescent lock and pulley; Sliding window type with actuator and handle multi-point lock, the required hardware accessories include push and pull handle, drive lock, single-point lock (slide fastener), pulley and auxiliary parts.

39. Hardware is generally charged separately and sold according to each set. Note that bad merchants will sell hardware according to parts.

40. If the merchant is all covered, ask clearly whether the hardware is domestic or imported. The import price is high but it can ensure smooth opening and closing windows for decades.

41. The better hardware brand is Noto, Germany. The official brand Noto has a round ROTO logo, which feels heavy, smooth but not loose, just like a machine that has not run away yet, very tight, but not a sense of obstacle; the logo of noto in china is pinyin NUOTUO, and the simplest one is to look at the logo of handle or linkage rod.

42. Looking at glass and profiles, laymen can feel it by feeling and looking. The inferior ones are generally thin, rough, not delicate and not smooth; The quality is generally thick, delicate and smooth, the quality always shows its unique charm in some subtle places.

43. In addition to materials, the installation level also affects the quality effect of Windows. It is best to go to the construction site where workers have already installed.

Window Measurement is the most prone to problems.

44. Don't wait for the old to be completely measured by the window. Some old ones will take a week. After the workers smashed the tiles beside the window in the old stage, they began to measure. Or measure at the beginning of the demolition and completion of hydropower transformation.

45. The measurement time should be as early as possible. Later, the manufacturer needs to confirm the drawings with you, and then go to the physical store to hand in the full payment. This process takes several days. When the full payment is handed in, the window will take 15 days to produce.

46. Generally, after the installation of windows is completed, balcony window sill of the windows need to be leveled and closed by the tillers, and even tiles need to be pasted by the balcony windows, so the windows must be installed before the tillers leave the site. If the hydropower transformation is relatively fast, the workload of tile workers is also very small, then the windows should be measured as soon as possible to ensure the smoothness of process convergence.

47. When measuring the window, it is better to have the foreman next to it to see if the construction size needs to be reserved. The size of the window is not equal to the size of the torn back wall frame, because the reduction of tiles, edging, stone window sill and ceiling should be considered.

48. Many merchants will not tell you that there is a loss in the window making process at first. Sometimes less than 1 ㎡ is calculated as 1 ㎡, and less than an integer is calculated as an integer. Finally, the settlement area will be more than the measured area.

49. In the same direction size, take the minimum value several times more! Because the wall is deformed, especially the old house, it is not necessarily horizontal and vertical when it is repaired, and it is not necessarily split when it is torn down.

50. Measuring windows is not only the accurate size, but also the common measurement results, calculation methods, whether there is any loss, etc. If there are more small windows in the house, the loss will be very large.

51. There are many area algorithms after measurement

Algorithm 1: The height before deduction X the width before deduction is much larger than the actual window area. The merchant will not tell you the deduction on the spot. Remember to deduct it before calculating it.

Algorithm 2: the living room window area is five into the kitchen window area is five into the bedroom window area is five into the bedroom window area, which will be one or two square meters more than (the living room window area, the kitchen window area, the bedroom window area), remember that after the total area of the window is calculated, it will be five in.

Algorithm 3: Total Area X loss ratio (1.2~1.5). The window has a loss ratio. For example, if the window edge of 2 meters 9 is used, the standard steel of 3 meters will be used, and the remaining 0.1 meters will be discarded. However, the specific loss ratio depends on the manufacturer's craftsmanship and their bargaining ability.

Owner example

On the last day, the actual area measured by our windows was 10.86 ㎡, not five. The first multiplication loss ratio was 1.15, equal to 12.489 ㎡, and then four rounds, equal to 12 ㎡. (I am honest people, not much bargain, the boss is also honest).

12 ㎡, standard 4 windows (seems to be the industry standard of broken bridge aluminum windows, standard 1 window for every 3 square meters), scott 60 thick 8 sealed 5 15 5 double-layer non-tempered glass unit price 590 yuan/1 ㎡, plus a corner, a window, a total of 7780 yuan, cut 80 yuan. The next day, I didn't trust the hardware and materials. I went to the boss's factory to have a look. I couldn't see a doorway and asked for comfort. Later, I went to his store and looked at it. I remembered the appearance of the hardware and materials after they were finished. When checking the goods, I compared them.

52. If you cook on the balcony and the smoke pipe is punched in the window, you must make it clear with the measuring designer. The window is installed and then punched, which is easy to break the glass.

Don't be fooled by the seller when the window fee is high.

53. The average market price is broken bridge aluminum. The whole package of 60 profiles should cost 500~600 yuan/㎡. If you go to the manufacturer yourself, it is recommended to ask a full package price, which generally includes hardware, glue and car window shade, and others may not include.

54. Some merchants offer only 200 or 300 square meters, but when installing, they will add extra money. Then they will be very passive. Try to write all the prices clearly at the beginning.

For example

There are three prices for the same product sold by the same merchant:

The first quotation: 280 yuan/㎡

It refers to the price of profiles. Generally, it does not contain hardware and glass.

Second quotation: 450 yuan/㎡

It is a quotation that everyone often hears, excluding hardware and middle column, and others. Ask clearly what it contains and what it doesn't contain.

The third quotation: 800 yuan/㎡

All inclusive, including all materials, but if you change tempered glass, coating or use good glue hardware, you may need to add extra money or buy it yourself.

55. In the process of measuring the quotation, the designer will calculate the area as much as possible, and the sales will try to hide the future expenses, reduce the price, and let you place an order.

56. Possible additional fees: coating fee, hardware fee, auxiliary materials fee, modeling fee, window opening fee, other fees.

Coating fee: apply a reflective and uv-proof film to the glass.

Hardware fee: all kinds of window parts.

Auxiliary fee: all kinds of glue and sealing strip.

Modeling fee: such as special-shaped or triangular ceiling on the side of the window.

Window opening fee: generally, it is 3 ㎡ to open a window. If the total area is 9 ㎡, only 3 windows can be opened. If you open more windows, you need to pay the bill.

Other fees: additional fees such as color, and even installation fees are charged separately by merchants.

57. We recommend that you separately record the unit price quoted by the merchant, the materials used for each item and the calculation method of the cost, and pin the sales list together. If an order is placed, this expense quotation details should be signed by the sales and pinned to the order.

58. To sign the contract, we must confirm with the manufacturer the size, model, thickness, material and several closed channels of aluminum. The price per square meter, whether there is any loss or not, and whether it is less than how many square meters is calculated by integer, in addition to what is included in aluminum and windows per square meter, it is better to draw a window size drawing or draw a picture so that the sales can be clearly marked out and where there is no charge.

59. After all unit prices and fees are confirmed, calculate the total price to see what the cost per square meter is. If it is too low, the merchant will definitely be able to find it elsewhere, and the appropriate profit will still be given.

60. The payment mode is basically that when placing an order, one hundred to several hundred yuan is given. The designer gives a part after measuring the size, and the final payment is given after installation or acceptance.

It is a waste to install windows that are unreliable and expensive

61. It takes a period of time to carry materials before installation. During this period, check whether each piece of materials meets the order as much as possible.

62. The width, thickness, glass material, thickness, whether the assembled part is defective or damaged, whether the hardware is complete, whether there are drainage holes under each open window, waterproof adhesive, styrofoam brands, etc.

63. Observe whether the surface of the window is obviously scratched or deluded, and whether there are cracks in the welding corner. The surface of the window should be smooth and smooth without open welding fracture. The sealing strip should be flat, no curling, no groove, and no smell.

64. If there are conditions before installation, prepare more paper box or cardboard on the ground to place window frames and glass to avoid scratches. Check whether there are people or cars under the window and whether there are hang the clothes downstairs, and make corresponding tips and protection.

65. Prepare a small brush. After installing a window, clean up the debris in the gap of the window frame to avoid sticking to the window gap when gluing.

66. Install all window frames first, and then install all windows. If you want to install guardrails, you must do so after installing windows.

67. There are many factors that affect the installation of broken bridge aluminum windows, and measurement, processing and installation cannot be ignored.

Owner example

a. My installation worker is good, very professional, very serious, the glass is very firm, and some small leather cushion will be put on it. The master said that the window will be relatively tight and not easy to loosen. These are their own years of installation experience.

B. The unit uses german xuge, and the materials are imported, but the installation person is very unreliable, and is outsourced to a small contractor. Later, the window leaks water, the glass layering quality is very poor, and there are many problems.

68. If the window frame of the outer wall is damaged, please decorate the workers with cement immediately. To repair the outer window frame, cement should be used to make a bevel to prevent rainwater from pouring back into the interior of the wall.

69. The open window edge strip is pressed on one side, with hierarchical order, and the effect of not installing in sequence will be very ugly.

70. After the installation is completed, use the worker's horizontal ruler to check it one by one. Including whether the window is vertical or horizontal, whether the handle of the window is horizontal, whether the hardware is installed firmly, whether the use is flexible, whether the opening and closing are smooth at various angles, etc.

71. The wall around the window is not very good. For example, if the house has been decorated for many times, it is very uneven to remove the window. It is better to spend money on waterproofing. If the window leaks rain, even after-sales glue is sometimes useless.

72. Finally, check whether the window leaks air and whether the switch is smooth. Try not to punch holes in the window glass. Rain may flow through the hole, and rain will be stored in the hollow glass.
