There are many factors to be considered in products, and the standardization of the market is very poor, so there will be many misunderstandings and traps when you choose doors and windows. Next, I will give you some suggestions on choosing doors and windows based on my own experience.
The first choice for choosing doors and windows is "broken bridge aluminum"
When buying aluminum alloy doors and windows, merchants may recommend broken bridge aluminum. Because aluminum alloy is a good conductor of heat, its thermal insulation is too poor, which affects comfort and environmental protection. Before the broken bridge technology came out, aluminum alloy basically withdrew from the choice of doors and windows because of thermal insulation problems, and the appearance of broken bridge technology saved aluminum alloy doors and windows. Therefore, in the decoration process, unless the hand is too tight, it is generally recommended to use broken aluminum doors and windows. In addition to its own comfort, saving energy and reducing consumption is also very important.
Choosing broken bridge aluminum depends on "system"
The method to judge the quality of a system mainly depends on the sampling angle of the profile. Usually, the tightness of the broken bridge and the sealing strip can reflect the quality of a system. The following points are easier to help you:
1) There are three rubber strips between the doors and windows, the opening fan and the door frame of the system.
2) The installation of the system door and window glass will never use silica gel, but will use two strips of glue inside and outside the glass.
3) The glass pressing line of system doors and windows cannot appear outdoors. As shown in the figure below:
How to choose the opening mode of residential doors and windows is also very important! Common window opening methods are: push and pull, outward opening, inward opening and upside down, hanging and so on.
Sliding windows used to be very popular, with low price, no space occupation and convenient use. However, the main problems of sliding window are poor sealing performance, easy air leakage and water leakage, and poor sound insulation performance. External window is also a widely used window type, its main feature is that it does not occupy indoor space. However, due to safety hazards and the risk of falling from high altitude, external windows are rarely used abroad, and Chinese codes also stipulate that external windows cannot be used in buildings with more than 7 floors.
Door and window details can not be ignored
Look at that corner
As we all know, the final quality of doors and windows has a great relationship with the processing capacity of processing plants, and one of the important indicators is corner fittings. The way to connect two profiles at the corner of doors and windows is to connect them with aluminum angle code, then squeeze the profiles and angle code together with an angle assembly machine, and then inject two-component glue into the hole to cure the angle code frame materials together. Commonly used low-quality practices are: no corner code splicing, corner code does not use curing glue, or this is to put a little on the mouth to deceive consumers. In addition, you can also judge the quality by touching the flat-fell seam of the supporting role. The smoother, the better the processing quality of the supporting role.
