Glass curtain wall is now the mainstream exterior wall decoration material, not only the appearance of glass curtain wall, but also the existence of many other functions of glass curtain wall. Today, let’s have a good understanding of the importance of glass curtain walls.

Doors and windows play a very important role in our current living. From the design point of view, we hope to have a good view and scenery when looking out from the house. At the same time, we also want to let plenty of sunshine into the house, so that we can feel the warmth of the home in the cold winter, and let the noise and rain Being able to be kept out of the house makes home our warm and safe harbor.

The glass curtain wall accounts for a large area in the doors and windows

The area of ​​glass in doors and windows is very large, so let us understand the influence of glass on doors and windows, and how to choose glass profiles suitable for window materials.

When we choose doors and windows, we often pay attention to the profile, hardware, wall thickness and other issues of the window. In this case, the salesperson will spend a lot of time introducing system profiles and hardware from various aspects.

Please don’t ignore the importance of glass curtain wall

Glass not only occupies most of the area of ​​doors and windows, but also plays a different role according to our needs for doors and windows. Next, I will introduce you to the knowledge and skills of identifying glass!

Whether it is tempered glass: The regular glass will be printed with the 3C certification passed by the country on the glass when it leaves the factory. Each glass processing factory has a 3C certification number, which must be printed on the finished glass. The 3C number on one insulating glass is E000449. By inquiring online, you will find that this number belongs to “a certain glass manufacturer”. Tempered glass must be printed with the 3C logo and number. If we see no 3C logo and number on the glass, it proves that the glass is not untempered, that is, it is produced by an unqualified glass processing factory. If we do not choose tempered glass, there will be many safety hazards when using doors and windows in the future.

The quality of insulating glass: the hollowing of glass is mainly for energy saving. Many conditions can judge the quality of the hollow glass, such as the aluminum strips in the hollow glass cavity. Regular glass companies use aluminum strips to bend the frame. Small glass processing companies will use 4 aluminum strip inserts to assemble (plastic). The main risk of the latter is that the plastic inserts are easily aged for a long time, causing air leakage in the hollow glass cavity, resulting in the generation of water vapor in the glass in winter, which cannot be wiped. In addition, the spacing of the glass in the insulating glass is generally 12mm, while the thermal insulation capacity of 9mm is poor, and about 15-27mm is very good.

Reduce UV rays with LOW-E glass curtain wall

Now more and more people know about LOW-E glass. From the perspective of energy saving, LOW-E glass has also been used as a standard configuration by many door and window manufacturers and has begun to claim that all glass uses this configuration. LOW-E glass is a Several layers of film are coated on the surface of the glass, which can play a good role in reducing ultraviolet heat insulation. However, many LOW-E glass are high-transparency products, which are not very different from transparent glass. Some door and window manufacturers use this to deceive consumers. So how to identify whether LOW-E is used in our doors and windows?

Generally speaking, the LOW-E film is on the hollow surface of the inner glass of the insulating glass room. When we look carefully from the side, we should be able to see a faint blue or gray film.

LOW-E glass Most door and window factories use offline single silver LOW-E, and online LOW-E is approximately equal to single silver in performance (there are more online LOW-E glass tooling, and LOW-E glass has been processed at the same time as mass production of glass. -E glass up).

Both tempered glass curtain wall and laminated glass curtain wall are called safety glass

Safety glass: Both tempered glass and laminated glass are called safety glass. The tempered glass will be broken after being hit with a sharp instrument, and the broken shape will be granular and will not hurt people. Laminated glass can play the role of anti-theft, anti-impact and drunk, etc. It is laminated with PVB film in two pieces of glass.

Glass sound insulation: Glass sound insulation is the basic condition for selecting windows. The window has good airtightness. On the basis of airtightness, the sound insulation ability of glass is very important. Normal sound is divided into high and low frequencies, and different glass thicknesses are very important for sound insulation. The ideal sound insulation effect is that the indoor noise level is less than 40 decibels. We can choose the suitable glass configuration according to our actual living environment.
