Newly renovated balcony for a year There will always be a rattling sound, not glass, what s going on

If it's a roof, you don't have to worry, it's normal, because the cement floor will separate under the pressure of heat on the wall plane, producing fine particles like hoops, and then these fine particles will move everywhere, producing sound, like glass marbles hitting the ground.

It may be a problem with the wood, or it may be that the cement is not solidified very well and goes to the shed, and the wood will absorb the water vapor of the cement that has not evaporated.

Then during the day, it is exposed to the sun, which causes it to dry out and crack, and it will make some bouncing sounds.

This is the sound caused by the phenomenon of thermal expansion and contraction of decoration materials.

The new house has been renovated for a year, and there is always a rattling sound on the balcony, if it is not glass, it must be a problem with the countertop of the balcony of your balcony, you should check it out to see if there are any traces of breakage.

In this case, it may be that the sun is too strong, so the sun has reached your balcony, mainly because there is no quality problem, basically there is no need to worry.

Do you mean that door soup on the balcony, or how cold door and window glass doesn't ring? Otherwise, you have that seal that is not good enough, not sealed enough, and when it is windy, there is a bouncing sound.

It should be the reason for the thermal expansion and contraction that makes such a sound.

Have you stopped reading the information? My family's situation is exactly the same as yours, and now I am very anxious to communicate with you about whether your home has been repaired.

Is there one at night, and I have it at night, but less than during the day.

What is the reason? Always running their own way. It has a relationship with the factory that can do it. That's what I thought. Scary.

What is usually the case?

It's tempered glass, and the breakage of tempered glass due to internal factors is called self-explosion. Self-explosion is unavoidable for tempered glass, and there is no warning, and the probability of its occurrence is usually 2 5, which is lower in Western countries and relatively high in China.

The inside of the glass may contain nickel sulfide impurities, which exist in a small crystal state, and under normal circumstances, will not cause glass breakage, but due to the reheating of the tempered glass, the phase state of the nickel sulfide impurities is changed, and the high temperature state of nickel sulfide is frozen when the glass is quenched, and it may take several years for them to return to the state. Due to the low temperature state of nickel sulfide impurities will produce a volume increase, in the glass to produce a local stress concentration, then the tempered glass self-explosion will occur. However, only relatively large impurities can cause self-explosion, and tempered glass self-explosion can only occur when the impurities are at the core of tensile stress.

Nickel sulfide can occur at any time after production is completed, and the most typical time to cause tempered glass to self-detolate is 4 to 5 years after the production of the product is completed.
