How to choose windows and doors?

Doors and windows, as one of the very important aspects of the house decoration process, not only affects the overall visual effect, but also meets our requirements for room comfort, warmth and safety. Windows and doors integrate a variety of materials such as profiles, hardware, glass and auxiliary materials, and the design needs to take into account aesthetics, structural mechanics and light and heat energy conduction control, noise control, wind pressure resistance, airtightness, watertightness, ease of use, durability and weather resistance and many other factors.

Products need to consider a lot of factors, at the same time, the market is poorly regulated, so we are in the choice of doors and windows, faced with a lot of misunderstandings and pitfalls, next, I will combine their own experience to give you some advice on choosing doors and windows.

Select windows and doors preferred "broken bridge aluminum"

We are shopping for aluminum alloy windows and doors, the business may recommend broken bridge aluminum. Because, aluminum alloy is a good conductor of heat, thermal insulation is too poor, affecting comfort and environmental protection. Before the bridge-breaking technology came out, aluminum alloy because of its thermal insulation problems basically withdrew from the selection of windows and doors, the emergence of bridge-breaking technology to save the aluminum alloy doors and windows. So in the decoration process, unless the silver is too tight, generally recommended or use broken bridge aluminum doors and windows, in addition to their own comfort, energy saving and reduce energy consumption is also very important.

Elect broken bridge aluminum also look at the "system"

The way to judge a system is good or bad, mainly to look at the profile sample corner section. Usually a bridge section and sealing tape tightness can reflect a system is good or bad. The following points are easier to help:

1) the system doors and windows, open the fan and the door frame are sealed with three rubber strips.

2) system doors and windows glass installation will never hit the silicone, are used in the glass, glass outside the two rubber strips.

3) The glass pressure line of the system doors and windows can not be outside. As shown in the following chart:

How to choose the opening of residential doors and windows is also important! Common window opening methods are: push-pull, external opening, internal opening and inverted, top-hung and so on.

Sliding windows were very popular before, cheap, do not take up space, easy to use. But the main problem of sliding windows is that the seal is not good, easy to leak wind and water, sound insulation performance is very poor. Casement windows are also used more of a window type, the main feature is that it does not take up indoor space, but due to the safety hazards of casement windows, there is a risk of falling from a height, very few foreign countries use casement windows, China's norms also stipulate that more than 7 layers of the building can not be used in the case of casement windows.

Details of windows and doors should not be ignored

Look at the corner

We all know that the final quality of windows and doors and the processing capacity of the processing plant has a relatively large relationship, one of the important indicators is the corner. Good doors and windows corner of the two profiles are connected with aluminum corner code connection, and then use the corner grouping machine to extrude the profiles and corner code together, and then inject two-component adhesive in the hole, so that the corner frame curing together. Commonly used low-quality practices are: no corner code splicing, there is a corner code does not hit the curing glue, or this is to play a little in the mouth to deceive consumers. In addition, you can also judge the quality by touching the group corner splices with your hand, the smoother it is, the better the quality of the group corner processing.
