Pay attention before customizing! How to consider glass safety for building exterior windows with too large window openings?

Regarding the insulating glass of doors and windows, I believe everyone is familiar with it. As a common heat and sound insulation safety glass, its main characteristics are high strength, not easy to break, and not easy to hurt people. So the question is, what else have we not noticed about the safety of window insulating glass?

Keyword 1: glass safety

Safety glass is not the same as glass safety. Glass production is not up to par, glass is not used correctly, and the temperature environment is unusual. The latter two are more common.

Under normal circumstances, the thickness of the door and window glass is not up to standard, the glass area is too large or the position is unreasonable, which may reduce the strength of the glass and increase unnecessary safety hazards. In addition, human or environmental factors can also cause the glass to burst, which needs to be paid attention to at all times.

Keyword 2: glass self-explosion

In general, the causes of self-explosion of tempered glass are roughly as follows:

1. There are visible defects or impurities in the glass (such as stones, sand particles, bubbles, inclusions, chips, scratches, edge explosions, etc.) that cause self-explosion;

2. Excessive nickel sulfide (NIS) impurities cause self-explosion of tempered glass (the diameter of nickel sulfide causing self-explosion is between 0.04~0.65mm, and the average particle size is 0.2mm);

3. The self-explosion of tempered glass is also affected by other factors: high outdoor temperature, unreasonable glass slotting and drilling, poor quality of original glass, uneven thickness (such as embossed glass, uneven stress distribution of bent tempered glass).

Keyword three: glass purchase

It is safe to buy and use with confidence. When we buy doors and windows, we should not only understand the details and functions of door and window products, but also understand the "origin" of door and window glass.

The workmanship (equipment and operation) and supply chain (quality of product materials) in the glass processing plant determine the quality of the finished glass used for doors and windows. After one to two years of use, insulating glass with poor quality is prone to problems such as spacer corrosion, molecular sieve precipitation, sealant aging and peeling, and water vapor ingress into the glass. These problems can cause insulating glass to lose its core thermal insulation properties, and it is more likely that the glass will not bond strongly, and finally cause safety hazards.

Therefore, when choosing doors and windows, we can correspondingly know whether the original glass of doors and windows comes from well-known brands, and whether the glass surface is printed with the 3C logo (whether it is a brand, you can search for its brand information on the Internet). If necessary, you should also consult the merchant about how long the warranty period of the glass is? What are the solutions when something goes wrong?

Keyword four: glass area

We all know that glass is much lower than the safety index of walls, so the glass of home doors and windows is not necessarily too large. The larger the glass area, the greater the pressure of the profile structure, and the greater the probability of the doors and windows bouncing and shaking; Moreover, with the increase of the area of floor-to-ceiling window glass, the thickness and strength of the single glass should also be improved accordingly, so that the glass has sufficient wind pressure resistance. For specific details, please refer to: The large-area glass window will shake as soon as it is pushed, and it will panic when it shakes? Finding out what the problem is is the only way to make the doors and windows more reassuring.
