What door should I use to decorate my room at home?

Generally speaking, the decoration and installation of doors and windows at home all hope that the quality of heat insulation and sound insulation is good, so let's explain the excellent aluminum alloy doors and windows: broken bridge aluminum.

First, the basic knowledge of broken bridge aluminum doors and windows

1, broken aluminum doors and windows.

The correct name should be "insulated broken bridge aluminum alloy doors and windows", which is used to prevent indoor (external) heat from flowing to outdoor (internal). Broken bridge aluminum is called broken bridge. A heat insulation strip PA66 is added in the middle of the aluminum profile, that is, the aluminum profile (alloy) is disconnected from the middle, and the disconnected aluminum alloy is connected into a whole through the heat insulation strip, thus achieving the heat insulation effect.

2. How to distinguish the quality of broken aluminum doors and windows?

First of all, look at the brand, the owner had better choose the top ten brands of broken bridge aluminum doors and windows in China; Secondly, look at the heat insulation strips in the middle of broken aluminum doors and windows. The high-quality insulation strips of broken aluminum doors and windows are all nylon, and the nylon strips of brand broken aluminum doors and windows are sprayed with electronic anti-counterfeiting codes, which are engraved on the insulation strips with lasers. Some businesses use PVC to cut corners.

3. The color of broken aluminum doors and windows.

The raw materials of broken-bridge aluminum doors and windows purchased from aluminum profile manufacturers are only white, light champagne and deep champagne, and the other colors are spray-treated powder, so that the colors of broken-bridge aluminum doors and windows can reach thousands. Moreover, plastic steel doors and windows are generally bluish white, even if color is needed, there are only more than 30 kinds of coated color steel doors and windows.

Second, the broken bridge aluminum door and window components.

Broken bridge aluminum includes profiles, hardware, glass, heat insulation strips, sealing strips, etc.

1, personal data.

There are two main types of profiles for broken aluminum doors and windows: punching type and glue injection type. Through-bar type is to connect the inner and outer parts of aluminum profile with two heat insulation bars, which prevents the conduction of heat inside and outside the aluminum profile and achieves the purpose of energy saving.

2. hardware.

Although the hardware fittings are unremarkable, they play a very key role in the broken bridge aluminum doors and windows, and the quality of the hardware fittings directly affects the performance of the broken bridge aluminum doors and windows.

3. insulating glass.

Select the insulating glass whose original piece is float glass, the thickness standard is 5 mm, and the thickness of aluminum gasket between two pieces of glass is between 12mm ~ 15mm, which should be set according to the specifications of door and window profiles. Generally speaking, the effective life of insulating glass is 8~ 10 years. During its use, there may be water vapor infiltration and water droplets, but it is a long process. According to the national regulations, insulating glass is considered as a qualified product after it has been used for 5 years. Insulating glass has excellent sealing and thermal insulation performance, mainly due to its special material. It is very simple to distinguish whether insulating glass is qualified in winter, just look at whether it is frozen inside and outside, and if it is frozen, it will be unqualified.

4. Insulation strips.

Broken bridge aluminum insulation strip is an important standard to judge the quality of broken bridge aluminum doors and windows. The current insulation strip market is divided into three levels: one is imported nylon insulation strip (PA 66 GF); The second is the domestic nylon heat insulation strip produced in 2003; Third, domestic PVC insulation strips; Among them, PVC insulation strips have long been eliminated. Compared with imported nylon glass fiber (PA66GF) insulation strips and domestic insulation strips, the differences are also obvious. The heat insulation strips without PA66 are unqualified products.

5. Sealing strip.

It is directly related to whether the broken aluminum doors and windows are tightly sealed.
