The first question that many people face when renovating a new house is: do the windows configured by the developer need to be replaced?
My suggestion is:
If there is a quality problem with the window (such as poor sealing, deformation, poor hardware quality or damage) at the time of delivery, it is recommended to contact the developer in time to request replacement or repair.
If the quality of the windows is acceptable, the function is normal, and the renovation budget is limited, you can consider not replacing the windows.
If the budget is sufficient and the requirements for sound insulation and insulation are high, you can consider upgrading to broken bridge aluminum windows, once and for all.
For now, broken bridge aluminum windows are the mainstream because of their good sound and heat insulation properties.
However, the customization process of broken bridge aluminum windows involves many links, including window frames, sealing strips, glass, hardware, accessories and other components.
In addition, due to the low starting threshold, there are many small factories and small workshops in the market, and we often say that the brand should be selected for doors and windows, because the quality and experience of the brand will definitely be different.
It is not easy to choose a reliable quality broken bridge aluminum window, and the broken bridge aluminum window contains:Window frames, glass, hardware, paving materials and other materials, but also to pay attention toMeasuring, machining, installationand so on.
Each of these links will affect the final use effect, below, we will teach you in detail step by step how to choose a good broken bridge aluminum window.
The thicker the profile of the window frame, the better the thermal insulation. Many people don't understand what they mean, but in fact, they indicate the thickness of the window frame, and you can measure it with a ruler.
When selecting profiles, it is necessary to look at the wall thickness of the profile according to the thickness of the window frame, and it is recommended that the wall thickness of the profile is not less than 14mm, because those below this value are inferior products, that is, non-standard.
1.The heat retention, wind resistance, and support performance below 4mm are very poor, and it will deform after a long time, so I have to say goodbye.
The wall thickness of the new national standard has been increased to 18mm, you can also buy it according to this wall thickness and you can't go wrong.
In addition, it is recommended to choose a well-known brand, although it is a little more expensive, but it is more secure!
The quality of the thermal insulation strip is related to the thermal insulation performance of the broken bridge aluminum window, which is very important, don't underestimate such a thing, the relationship is big.
Good thermal insulation strips are all PA66, because PA66** is expensive, so some bad merchants will replace it with inferior PVC, so pay special attention.
Because the sealing of PVC insulation strip is poor, there is a risk of deformation and cold shrinkage, and air leakage will occur after a long period of use.
When purchasing, you can use a lighter to identify, if it is flammable and has a burning smell, it is likely to be made of PVC.
Common glasses include insulating glass, vacuum glass, laminated glass, etc.
If you want to have a good thermal insulation effect, choose the empty glass, which has a first-class thermal insulation effect.
If you want to have a good sound insulation effect, choose laminated glass, which adds a layer of PVB film to the inside of the laminated glass, which can improve the sound insulation effect, and in case the glass explodes, the broken glass slag will not fly out if it is sticked.
In addition, it should be noted that the glass is best tempered, and the glass has the CCC logo.
Hardware is related to the service life of broken bridge aluminum windows, you must choose the brand, don't save money in this regard.
If the merchant packs hardware, it is necessary to ask what brand it isIs it imported or domestic?
If the hardware is charged separately, you can choose the hardware of the big brand yourself.
When choosing hardware in the market, we should also pay attention to distinguishing the authenticity, which is generally marked with anti-counterfeiting labels and written query methods.
Ask whether it is sold as a whole set or as a single piece, because some look at the unit price of each piece is not high, but it is very expensive when it comes together.
In addition to the above precautions, there are also some potential additions to the aluminum windows of the broken bridge.
Measuring Area:There are many tricks in the measurement of windows, such as less than 1 square meter is counted as 1 square meter, less than an integer is counted as an integer, and the outermost edge of the window is measured according to the shrinkage gap between the window and the wall, so when it comes to settlement, it is found that the area is more than the actual measurement.
There is an additional charge for opening the window and sashing:For example, an 8-square-meter window can only open 3 windows, if you want to open more, you have to add money, open one more and add a few hundred.
Sealants, styrofoams, etc.:The total price of some merchants does not include these, and additional money is required, and what brand of glue is it, ** The difference is also very large, these must be clarified in advance.
There is a minimum area limit:For example, there is a limit to the area of a single window sash, and if there is not one square meter, it will be counted as one square meter, and if the window sash is less than two square meters, it will be counted as two square meters, etc.
What elseColor change, coating, opening, beam, subframe, four-linkAnd so on, there are many bad businesses that need to be added separately, and these should be clarified in advance.
Otherwise, your eyes will be black, you won't know anything, and you can only consider yourself unlucky.
It is recommended to choose Mercer doors and windows, Mercer doors and windows are really the boss in the industry, and they can't find a little bit of badness, and all they find are advantages.
The brand is made in Germany, which has long been known for its superb technology and high standards of quality.
Mercer doors and windows have the characteristics of systematic design, high-quality raw materials and hardware systems, German standard technology, rigorous production lines, etc., to provide high-efficiency and energy-saving door and window solutions for global buildings.
Mercer doors and windows ensure the long-lasting service life of windows and doors, and can improve the quality of living, and have more all-round advantages than ordinary doors and windows in terms of sound insulation, insulation and safety.
Mercer's doors and windows have five core features that highlight his excellence:
Core.
1. Systematic design: Mercer doors and windows have a strong R&D team, and have been leading the world industry standard for doors, windows and curtain walls.
Core twoHigh thermal insulation profiles: In Germany, most of the residential windows are made of UPVC profiles or thermal insulation bridge aluminum alloy profiles, and all window frames and sash profiles are cavity structures, and the wall thickness and strength of the profiles are higher than China's national standards.
Core threeGerman standard material formula: The UPVC profiles produced by the German process have high strength and aging resistance due to different material formulas, and have obvious advantages compared with China.
Core FourHigh-quality hardware system: The hardware system of German doors and windows has a higher degree of fit, and has been rigorously tested to ensure the stability and durability of windows and doors.
Core FiveRigorous production process: The most important material for doors and windows is on the one hand, and the production process is even more critical, and the process is not in place, which is also difficult to withstand the test of time.
