The word namaz in the word means the outer shell and appearance of any object that shows itself at the first glance. In the building, the outermost wall of the building is called facade. The facades of buildings are exposed to external factors such as strong sunlight, frosts, chemical and atmospheric factors, etc., and therefore, over time, they suffer damage and need to be restored.
Reasons for facade renovation

Reconstruction of the facade due to providing strength:
In the distant past, the facade of the building was a part of the building, and the strength of the facade was directly related to the strength of the whole building. While today, most of the facades are separate shells in front of the outer wall of the building. The materials used in the facade or connecting the facade to the wall are subject to wear and tear for various reasons, which must be restored before any disaster occurs.

Reconstruction of the facade due to beautifying the visual effect:
The facade of the building has very direct psychological effects on its observers. Many workplaces are trying to improve their work process by using this trick and designing and implementing modern building facades. In addition, in the reconstruction of the facade, care should be taken to ensure that the facade of the building is in complete relation with its surrounding environment so that it does not disturb the visual effect and the urban appearance in a unified whole.
