As one of the most important links in the process of house decoration, doors and windows not only affect the overall visual effect, but also meet our requirements for room comfort, warmth and safety. Doors and windows integrate various materials such as profiles, hardware, glass and auxiliary materials, and many factors such as aesthetics, structural mechanics, conduction control of light and heat energy, noise control, wind pressure resistance, air tightness, water tightness, convenience of use, durability and weather resistance need to be considered in the design.

There are many factors to be considered in the product, and the market standardization is very poor, so there will be many misunderstandings and pitfalls when you choose doors and windows. Next, I will give you some suggestions on choosing doors and windows based on my own experience.

"broken bridge aluminum" is the first choice for choosing doors and windows

When you buy aluminum alloy doors and windows, the 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 selection of doors and windows because of its thermal insulation problem, and the appearance of broken bridge technology saved aluminum alloy doors and windows. Therefore, in the decoration process, unless the money is too tight, it is generally recommended to use broken aluminum doors and windows. In addition to their own comfort, it is also important to save energy and reduce energy consumption.

The selection of broken bridge aluminum depends on the "system"

The method to judge whether a system is good or not mainly depends on the cross section of the profile sample angle. Usually, the tightness of a broken bridge section and sealing strip can reflect the quality of a system. The following points are easier to help you:

1) There are three rubber strip seals between the system doors and windows, the opening fan and the door frame.

2) The installation of windows and doors of the system will never use silica gel, and both of them use two rubber strips inside and outside the glass.

3) It is impossible for the glass pressing line of the system doors and windows to appear outdoors. As shown in the following figure:

How to choose the opening mode of residential doors and windows is also very important! Common window opening methods are: push-pull, outward opening, inward opening and upside down, hanging up, etc.

sliding windows were very popular before, with low price, no space occupation and convenient use. However, the main problem of sliding window is poor sealing, easy to leak air and water, and poor sound insulation performance. Exterior window is also a kind of window type that is widely used, and its main feature is that it does not occupy indoor space. However, due to the potential safety hazard and the risk of falling from high altitude, exterior window is rarely used abroad, and China's code also stipulates that exterior window cannot be used in buildings with more than 7 floors.

the details of doors and windows can't be ignored

Look at the corner

As we all know, the final quality of doors and windows has a great relationship with the processing capacity of the processing plant, and one of the important indicators is the corner. A good way to connect two profiles at the corner of doors and windows is to connect them with aluminum corner codes, then squeeze the profiles and corner codes together with an angle assembling machine, and then inject two-component glue into the holes to solidify the corner code frame materials together. Commonly used low-quality practices are: splicing without corner codes, not using curing glue for corner codes, or this is to cheat consumers by putting a little on the mouth. In addition, you can also judge the quality by touching the flat-fell seam of the assembly angle with your hands. The smoother it is, the better the processing quality of the assembly angle is.
