Anonymous users2024-01-23The sound insulation performance of steel and aluminum windows is about 19 decibels, and the sound insulation performance of plastic steel windows can reach more than 30 decibels. In an increasingly noisy urban environment, the use of plastic steel windows can make the indoor environment more comfortable. ACCORDING TO THE TEST OF THE BEIJING INSTITUTE OF LABOR PROTECTION, THE INDOOR NOISE OF THE PLASTIC STEEL WINDOW IS REDUCED TO 32DB(A), AND THE EFFECT IS VERY GOOD.
Due to the development of the economy, the problem of urban noise is becoming more and more serious, and plastic steel windows will provide a great contribution to improving the quality of the sound environment where people live and work. In addition, plastic steel windows are corrosion-resistant, can be used in coastal areas, chemical plants and other corrosive environments, and ordinary users can also reduce the labor and cost of maintaining paint. The structure of the large slab floor glass is simple, and the sealing treatment is insufficient.
In addition, large pieces of glass will resonate with large decibel noise. At the same time, the thickness of the glass used is different, the sound insulation effect is also different, and it is a bit cumbersome in practice.

Anonymous users2024-01-22It's not legal for you to do this, and now you're in the city.
According to national law, the change of the façade of the building must be approved by the relevant departments. Enclosed balconies also count. Of course, in practice, it generally doesn't matter. >>>More
If this balcony window is the original of the house, then look at the specific reason, if it is a quality problem, it is the developer and builder who are responsible for it during the warranty period, and the owner is responsible for it after the warranty period. It doesn't matter if there is any man-made reason for the property, unless you have evidence that the property was caused by negligence.
1. Whether it is legal for the property to forcibly close the balcony at the specified time depends on whether the decoration time required by the property is a reasonable time, and it is generally not possible to decorate and construct after 8 o'clock in the morning and 10 o'clock in the evening. If you think that the property management requirements are unreasonable or have objections, you can report them to the property management department of the local housing authority. >>>More
Generally speaking, you just do what the property says. If a small amount of money is involved, there is no need to worry about whether it is legal or not.
You can find a property, and the property generally requires the balcony to be uniformly closed.
