Aluminum alloy doors and windows are standard for exterior doors and windows in Guangdong. At the same time, with the national promotion of environmental protection, the rise of broken bridge doors and windows is on the rise, which further ignites the popularity of the market. However, a large number of bad enterprises poured into this home market, causing chaos in the home market and lowering the image of aluminum alloy doors and windows. The choice of aluminum alloy doors and windows is very difficult to choose in the eyes of ordinary owners who do not know this line. In particular, the price of aluminum alloy doors and windows has captured the hearts of consumers.
Next, let's continue to say yesterday
The following is hardware. If it is not all-inclusive, no charge depends on the merchant.
55. 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.
56. 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.
57. 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.
58. Hardware is generally charged separately and sold according to each set. Note that bad merchants will sell hardware according to parts.
59. 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.
60. 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.
61. 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.
62. In addition to materials, the installation level also affects the quality effect of Windows. It is better to go to the construction site where workers have already installed.
The window measurement is the most prone to problems.
63. 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.
64. 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.
65. 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.
66. 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.
67. 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.
68. 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.
69. 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.
70. 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.
The 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.
71. 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 merchant when the window fee is high.
72. 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.
73. 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.
Take an 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.
74. 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.
75. 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.
76. 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.
77. 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.
78. 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.
79. 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.
80. 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.
81. 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.
82. Observe whether the surface of the window is obviously scratched or grooved, 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.
83. 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.
84. 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.
85. Install all window frames first, then install all windows. If you want to install guardrails, you must do so after installing windows.
86. There are many factors that affect the installation of broken bridge aluminum windows, and measurement, processing and installation cannot be ignored.
The 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.
87. 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.
88. 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.
89. 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.
90. 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.
91. 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.
There are still many problems in the aluminum alloy door and window home industry. Xiao Shunzi, I took the worry of being attacked and told some of them. If you think it's OK, give a little praise and add a collection to encourage you. If you feel that it may be useful to have friends and families decorating, you can also forward it to help more people.
