Reasonable increase in the quotation of broken bridge doors and windows
1. Glass
at present, in the merchant's quotation of broken bridge doors and windows, except for the 80 series broken bridge aluminum doors and windows the standard is three-layer hollow glass, 65 series and 70 series, and the original standard is double-layer hollow float glass.
1. Upgrade the double-layer glass to Triplex glass
if you have special needs, such as high requirements on the thermal insulation and sound insulation performance of windows, or the street side of the community, you want to upgrade the double-layer glass to Triplex glass, the extra layer of glass needs to be charged separately, which is a reasonable increase.

2. Upgrade ordinary glass to tempered glass
the standard double-layer glass of the merchant is 5mm ordinary glass. If you want the safety performance and stability of the glass to be stronger, you need to upgrade the ordinary glass to tempered glass, then this tempered glass also needs to be charged according to the amount of square meters, which is also a reasonable increase.
3. Upgrade ordinary glass to coated glass
if you have high requirements on the privacy of Windows, you need to upgrade ordinary glass to coated glass (coated glass cannot be seen from the outside), which also requires a separate charge.
"Therefore, as long as the standard hollow glass is upgraded, additional fees are required, which is a reasonable increase.

2. Secondary frame
if the window involves a tile, a marble countertop or a covered window, the width of some window frames is not enough. After the tile is attached or the covered window is covered, the hinge part will be blocked, the doors and windows cannot be opened properly.
In this case, you need to add a edge strip of about 2.5cm below the hinge or window sill to increase the width of the window frame and solve the problem of window opening, the added edge strip is the secondary frame.
Adding such sub-frame is not in the standard quotation of broken bridge doors and windows, but also requires extra charge, which is also a reasonable increase.
3. Corner
the so-called corner is that when the window encounters an L-shaped or U-shaped balcony, a 90-degree or 135-degree corner should be added to the corner of the balcony, this is not within the standard range, and additional fees are required. This is also a reasonable increase.
4. Flat hanging hardware
generally speaking, the standard hardware of the merchant is flat opening, which means that there is only one way to open the window.
Now there is a kind of flat open window, that is, on the basis of flat open, the window can be opened at an elevation angle of 15 degrees, which can not only ventilate, but also not occupy the indoor space.
Therefore, if you want to upgrade to this open mode, you need to add a set of hardware with the function of hanging, then this set of hardware needs to be charged extra, which is also a reasonable increase.
5. Upgraded Version car window shade
the normal standard in the quotation of broken bridge doors and windows of merchants is the roller shutter type car window shade, which is invisible car window shade. When using it, pull voile down. When not using it, voile is automatically rolled back to net box, which does not occupy space.
However, the car window shade material of invisible voile is glass fiber, which is easy to age and has a short service life. Moreover, it cannot be easily removed and is not easy to clean and take care of. Therefore, many consumers will choose to upgrade to flat-open removable and washable car window shade, this will facilitate removal and cleaning.
In addition, considering the service life and anti-theft performance of car window shade, some consumers will also be willing to upgrade the ordinary invisible car window shade to Diamond Net car window shade.
Therefore, if you upgrade ordinary invisible car window shade to ordinary flat-open removable car window shade, or upgrade to Diamond Net car window shade, you will need to charge extra fees, which is also a reasonable increase.
6. Special-shaped window
the so-called special-shaped window is a very shaped window. Because the process of special-shaped windows is relatively complicated, the cost is relatively high.
For example, the area of a circular arc window is calculated by multiplying the length by the height of the highest point of the arc, while the area of a common window is multiplied by the length by the width. Therefore, a charge is charged for the profiled price8com in the upper half.
In addition, special-shaped profiles and special-shaped glass also need to be charged separately.
Generally speaking, the more complex the profiled window is, the higher the charge will be. This is also a reasonable additional Charge item.
Broken bridge aluminum doors and windows unreasonable addition
1. Area increment
the first unreasonable increment is the area increment.
The normal window area is calculated by multiplying the length by the width. As long as the window area is more than 2 square meters, the merchant has to calculate and charge according to the actual size.
Here is one point to explain that the area of a single window is less than 1.5 square meters. We need to calculate it according to 1.5 square meters. If it is more than 1.5 square meters, we need to calculate it according to the actual area of the window.
If a single window is less than 1.5 square meters, it will be calculated as 1.5 square meters. This is because even if a single window has a small area, it also needs to open the window, equipped with hardware, equipped with car window shade, etc., and also has material loss, etc, so this is a reasonable charge.
However, some merchants on the market, after rounding the calculation area charge, use the cover of material loss to calculate a part of the area, and add a material loss fee, such as a 15 square meter window, he will calculate the area of 3 or 4 square meters for you, then the charge of these 3 or 4 square meters is unreasonable and malicious.

2. Hardware
A complete set of hardware includes handles, hinges, locking points, connecting pieces and window locators.
If the merchant takes these apart and sells them to you, and charges for these hardware accessories one by one, then this is definitely a malicious addition.
3. Price increase
some merchants will lower the unit price, and then charge fees on other accessories to make up the difference, for example, charge for the beam or column of the window.
As we said earlier, beams and columns are actually the basic components of broken bridge aluminum windows, which have been included in the quotation of broken bridge doors and windows per square meter, if the merchant charges extra fees or charges fees on the excuse of adding a few beams or columns, it is unreasonable to add malicious items.

4. Glue
the fourth unreasonable addition is glue.
The glue used in the window decoration process is Styrofoam, waterproof adhesive, and silicon sealant.
After installing the window, first fill Styrofoam around the window frame, then waterproof the window with waterproof adhesive, and finally seal and fix silicon sealant after the window glass is installed.
This is the three kinds of glue that must be made during the window installation process, which is indispensable. In principle, these three kinds of glue are included in the quotation per square meter of the merchant, and there is no charge, however, some merchants will attract consumers by lowering the quotation of broken bridge doors and windows, and then make up the difference by charging these gluing fees.
What is more terrible is that the extra glue fee is charged at linear meter yuan. The price generally ranges from 10 yuan to 20 yuan, which seems not expensive, but the calculation of three circles inside and three circles outside, only one glue cost may account for about 30% of the total amount of door and window decoration, which is an unreasonable malicious addition.
However, there is an exception, that is, if consumers consider environmental protection and upgrade the standard silicon sealant to more environmentally friendly imported glue, then they need to pay extra fees, this is a kind of reasonable increment. Styrofoam and waterproof adhesive do not have the problem of product upgrade. If the merchant charges, it is a malicious addition.
5. Car window shade
as mentioned earlier, like beam, column, and glue, invisible car window shade belongs broken bridge aluminum doors and windows the standard decoration is included in the quotation of the broken bridge doors and windows of the merchant. If the merchant charges extra for the invisible car window shade in the standard, it is an unreasonable malicious increase.
However, if you want to upgrade the standard invisible car window shade, you need to charge extra fees, which is a reasonable increase.
6. Color selection of doors and windows
broken bridge aluminum doors and windows the color can be selected according to the user's preferences, and there is no charge for this.
7. Others
regular merchants also do not charge any fees for arranging on-site measurement, drawing, transportation, dismantling, installation, etc.
Finally, remind consumers to buy broken bridge aluminum doors and windows in addition to paying attention to the price, it also depends on whether the raw materials used by the merchant are original aluminum profiles and whether the heat insulation strip is nylon heat insulation strip.
If it cannot be identified by naked eyes, it is better to check the quality certification certificate of the merchant or go to the factory to check the processing process in person to ensure that the formal and qualified ones can be bought. Broken bridge aluminum doors and windows product.
