Among the large hard-mounted pieces, broken bridge aluminum windows are the most unpredictable. The reasons are as follows:
1 . The price is expensive, just do it for tens of thousands.
2 . If you add a lot of items, you can make more than 1,000 items with glue.
3 . The brand is mixed, and there are too many small factories and workshops, 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 . 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.
6 . The angle codes of regular door and window manufacturers are all made of aluminum profiles with a wall thickness of not less than 3mm. Swarthy merchants replace aluminum profiles with plastic ones. The appearance is very ugly, and only a little can be seen from the gap.
Measurement what are the precautions in the process?
Most people's balcony walls are not completely horizontal or vertical, and the same plane needs to be measured in multiple places to avoid tragedies with large gaps or inaccessibility.
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 many houses with small windows, the loss will be very large.
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.
Before measuring, try to go to the factory if necessary, and look at the sample workmanship on site, focusing 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.
The payment mode is basically that after designers measure the size, they will pay a part of the deposit after signing the contract and the final payment after installation or acceptance.
What details do you need to pay attention to in the installation?
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.
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.
It is better to supervise the whole process. If the decoration is improper, it will be difficult to rework later.
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.
The outside is close to protective grating, and car window shade installation position must be reserved. I have seen a car window shade one that cannot be installed, resulting in rework.
The installation of Windows should be before the brickwork leaves, because some windowsills need to be leveled and closed by the bricklayer.
Just installed the window, try to avoid the construction and cleaning of dust. It will be covered with dust only after waterproof adhesive and 12 hours.
Install all window frames first, and then install all windows. If you want to install guardrails, you must do so after installing the windows.
After the decoration is completed, it will take about car window shade to install. 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.
Usually to the window what are the cognitive misunderstandings of household profiles?
Window brands generally focus on profiles, while others such as glass and hardware are not necessarily the best. Hardware generally requires brands.
Window selection brands are more profile selection, glass, hardware and other brands have separate brands, such as float glass and Noto hardware.
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.
Insulation strip is nylon (PA66), resistant to 300℃ high temperature, counterfeit products are generally replaced by flammable PVC material, which can be identified by lighter.
Generally speaking, the wall thickness of the national standard must be greater than or equal to 1 .4mm, less than 1 .4 is inferior, take 70 as an example, the wall thickness is 1 .4mm, 1 .6mm, 1 .8mm.
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.
Different situations how to choose window glass?
Tempered glass has good safety. If the glass is broken, it will become granular and will not hurt people. Hollow glass has good sound insulation and heat preservation effect.
Now all tempered glass has CCC logo. In the corner below the window, generally tempered glass needs to be charged extra.
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.
For safety, try to be greater than 1 .5 ㎡ windows are tempered.
If hollow glass is selected, the hollow thickness of 12mm or more is generally selected to achieve the heat preservation effect, and the glass on both sides should reach the thickness of 4~5mm.
Double-layer recommend mm 12mmA 5mm, three-layer push 5mm 6mmA 5mm 6mmA 5mm, where A indicates the degree of intermediate air layer, and others represent the glass thickness. (The specific choice of hollow glass is determined by the profile series and the intermediate interval of the profile)
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, which requires additional cost.
If the merchant cannot make low-e film, try not to apply coating. Other coating will affect the indoor light.
What are the details of window accessories that are easy to be ignored?
Recommend use diamond Net car window shade, anti-theft, anti-mosquito and anti-fall, safety first. While choosing invisible car window shade, watching with damper or not can avoid car window shade noise.
Some merchants include waterproof adhesive of the fee, while others do not. Try to include waterproof adhesive, because the usage will be large.
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.
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.
7-way Seal 10 it is better to use better sealing strips for channel sealing. Choose tough and elastic, do not choose particularly hard, especially in northern weather, can not be used, recommend EPDM or floating on water.
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.
A large amount of glue will be used during installation. It is best to calculate it into the cost per square meter, negotiate with the merchant to use the brand and sign the contract.
Styrofoam long time easy to break, leaking, outside the window Styrofoam dry, use wallpaper knife to cut off the excess, and then use silicon sealant to seal.
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.
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.
When the windows are large and several are connected, you must fix them with columns.
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.
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.
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.
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 not easy to deform. Its firmness, safety and strong wind resistance are greatly enhanced.
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 absolute sealing effect. Some merchants will charge separately.
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 of them replace aluminum profiles with plastic ones. The appearance is hard to see, and only a little can be seen from the gap.
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.
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.
The above are all window accessories, which are generally not included in the window if they are not all covered.
Hardware of doors and windows how important is the bottom?
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.
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.
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.
Hardware is generally charged separately and sold according to each set. Pay attention to that bad merchants will sell hardware according to parts.
If the merchant is all covered, ask whether the hardware is domestic or imported. The import price is high, but it can ensure smooth opening and closing windows for decades.
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.
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.
Why is measurement the most prone to problems?
Don't wait for the window to be measured until the old ones are completely removed. 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.
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.
Generally, after the installation of Windows is completed, balcony window sill of the windows need to be leveled and closed by the tiles, and even the tiles need to be pasted by the balcony windows, so the windows must be installed before the tiles 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.
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.
Many merchants will not tell you that there is a loss in the window production 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.
In the same direction, the minimum value should be measured 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.
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 many houses with small windows, the loss will be very large.
After measurement, the area algorithm includes A lot
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, 3 meters of standard steel is used, and 0 is left. .1 meter will be discarded. However, the specific loss ratio depends on the manufacturer's craftsmanship and their bargaining ability.
What will happen if the installation is unreliable? Some serious consequences?
It takes a period of time to carry the materials before installation. During this period, check whether each piece of materials meets the order as much as possible.
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.
Observe whether the surface of the window is obviously scratched or ungrooved, 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.
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.
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.
Install all window frames first, and then install all windows. If you want to install guardrails, you must do so after installing the windows.
There are many factors that affect the installation of broken bridge aluminum windows, and measurement, processing and installation cannot be ignored.
