Depending on the quality, of course good windows cannot be replaced, but poor windows must be replaced. Therefore, the key point is whether the windows installed by the developer are good or bad. How to identify them?

The simplest way is to look at the number of glass layers. If it is a single layer, it is an old-fashioned window, whether it is aluminum or plastic steel. New energy-saving soundproof windows are all double-glazed. If the glass is still single-layered, its sound insulation and energy-saving effects are very poor, so it is recommended to replace it; if it is double-glazed, at least it is a new type of window, even if the quality is poor, it will be better than Single-glazed windows more than double the performance.

General commercial houses are already equipped with double-glazed windows. This is an engineering decoration. Such windows basically meet the national engineering acceptance standards. However, the national standards often pay too much attention to rigid indicators and safety. Correspondingly, They don’t care much about people’s user experience, which is why the windows installed by many developers feel very stiff, very uncomfortable to use, difficult to open and close, and are dim in color. Therefore, if the economic conditions are not that good, users can make do with it. There is no need to replace it, after all, its basic performance has been accepted by professional institutions.

However, if the color of the doors and windows obviously does not match your decoration style, the doors and windows are difficult to open and close, stuck, and uncomfortable to use, or you live on the side of the road, on a low floor, and the noise is too loud, etc. If economic conditions permit, it is best to replace the developer's doors and windows.
