Why should we choose the best facade for the building?
It is necessary and necessary to know what purpose or goals the consideration of facades for buildings pursues, and what factors are effective in the type and execution method of such facades. But the point that should be mentioned here and before discussing the goals and types of facades is that the design of the facade for any building and at any cost that is built, must be maintained completely correctly and in principle, and in case of damage to the facade , in order to avoid more serious damage and ultimately the destruction of the entire facade and building, as well as in order to preserve and revive the view and appearance of the building, the damaged parts must be completely restored and repaired.
5 reasons for building facade design
- Making the appearance and exterior of the building beautiful and pleasant, and finally a suitable and acceptable view of the city or the place where the building is located.
- Reducing energy loss. in all seasons; Because the facade in the building plays the role of a thermal and cold insulation, which prevents waste on the production energy of the heating and cooling systems of the building, and can, depending on the material, color and amount of the surface, cause heat rejection and reflection in the season. summer, especially in tropical regions, and perform the same function in winter to absorb solar energy and heat buildings in cold regions. It is quite clear that the facade of the building plays a very important role in reducing the amount of noise pollution and disturbing sounds from the outside environment into the interior of office and residential buildings. This problem is more apparent in megacities with high noise pollution.
- In today's constructions, sound insulation is done by using glass facades and by using multi-layered glass between them. It is filled with gases such as argon or vacuum, it has reached better results with higher efficiency. Facades made of stone, concrete and brick are also good insulators in terms of sound.
- Helping to increase the durability and stability of buildings against unfavorable atmospheric and environmental conditions (earthquake, wind, acid rain and humidity) corrosive, frost, acid gases in the polluted air of big cities, harmful rays of the sun such as ultraviolet rays, dust and soot containing chemicals) and as a result increase the useful life of the building.
Facilitation of work and using mortar:
In this method, according to the atmospheric and environmental conditions of the region, the type of materials under the work surface, in terms of water and moisture absorption, resistance and adhesion, etc., cement, plaster, mud, limestone or a combination of them are used. For example, in terms of resistance, cement mortars have the highest resistance, and mud and plaster mortars have the lowest resistance, respectively. Therefore, if you need a facade with high resistance, you can never use plaster or clay mortars. But on the contrary, the formability and setting of plaster facades is more and faster than cement types.
Facade using external coatings:
Among the other facade building methods is the use of exterior coatings such as glazed, traditional and zeiger paints of all kinds of colors, as well as the use of coatings made with resin materials such as acrylic resins, alkyd, polyester, phenolic, nitrocellulose, etc. is.
