Reduce runtime With the passage of time and the advancement of technology in the construction industry, time plays a fundamental and very important role in this industry and the methods designed and proposed by building experts have all been weighed against this important factor and it can be said that with the benchmark of this important factor lasting Have been destroyed. With a little reflection, we find that dry façade can reduce the execution time by up to 50% and even reduce the negative effects of ambient temperature to about zero, and due to the lack of mortar and traditional methods, it is possible to activate several fronts simultaneously in the upper sections. And the downside increased the speed of execution more and more, and of course other cases such as the use of trained teams, instead of traditional and non-technical forces and lack of training in old, traditional methods, as well as the use of industrial tools and machines to do things in modern methods. In addition to having a direct impact on execution time and preventing possible rework, it will certainly have a significant impact on increasing the quality of execution. Of course, another advantage of dry methods that have a great impact on the completion time of projects is the possibility of starting the facade with a short distance from the end of the building skeleton.

For many years, facades inside and outside the building have been executed by people without the necessary training with sand and cement mortar, which apart from imposing high weight on the building, which due to the importance of buildings are resistant to earthquake force and direct relationship between earthquake lateral force and weight Due to the different coefficients of heat transfer and also the different rate of expansion and contraction of the mortar part behind the stone or ceramic, etc., compared to the exterior materials and the existing hardening part, we see that over time, the stones have separated. And even wire scoops do not prevent them from falling

Due to the precise technical and engineering design of the facade, including the infrastructure and precise design of the dimensions and plates for each project according to the openings, building height, use and other factors and the possibility of ordering stones and consumables while reducing waste and execution time , Will have a significant impact on the quality of performance.

With the industrial production of facade substructures, including iron, aluminum or galvanized and steel profiles, as well as facade materials, the possibility of human error in various sectors, including the percentage of mortar mixing, etc., will be greatly reduced and therefore will have a significant impact on increasing quality.

One of the problems that we usually see in traditional methods is the creation of non-coplanar joints that occur after grouting due to the displacement of stone, etc. and out of the initial regulation, and usually can not be repaired without damage, but in dry methods because No hardening material (mortar) is used, During the execution and even after the completion of the work, it is possible to easily adjust the possible errors, even up to a millimeter, and even during the years of operation, it is possible to move and correct each stone or ceramic, and so on

Reduction of about 100-80 kg of weight per square meter of the facade surface compared to the slurry method, which will have a great impact on reducing the seismic force, and if the facade is seen dry at the beginning of the building design, with a significant reduction in building weight Not only will the cost not increase, but the weight of the skeleton and foundation will also have a significant reducing effect on the final price.

It is important to note that ordinary facades definitely need to be repaired and re-enclosed after a few years, which
means imposing additional costs that the employer has to bear for the facade after a while, and at the end of the work
due to the useful life of the grout. It is about 10-15 years old, the whole layer of mortar as well as the relevant stone
should be demolished, which means that if a cost is spent for the implementation of grout facades after the
completion of the building, it should be considered completely depreciated.
However, in the implementation of dry facades, due to industrial installation, there is no need for repair and
maintenance costs over time, and in case of damage, each of the plates can be repaired and replaced, and there is
no need for total destruction or repair, even after Its useful life (over 50 years) can be used to recycle all materials
used, including substrate metals (ferrous or aluminum) and most importantly the consumed stone or ceramic, and
each of these materials in other places and neighborhoods depending on the type. The user, and this means that all
costs incurred for the implementation of this facade will be returned to the employer after the completion of the
building, in terms of a standard percentage of material depreciation.

As mentioned before, reducing the weight of the building is directly related to reducing the seismic force on the buildings and will be in line with the remarks and special points of the Iranian Earthquake Code (2800) and other earthquake regulations in the world and infrastructure design and materials of each facade based on standard design principles. And is in accordance with the conditions set forth in Iranian Bylaw 2800 and is connected to the main structure of the building, which means that during an earthquake, the facade and related accessories are moved separately by changing the lateral location of the structure and this prevents the facade from flaking and parts falling. It will be similar to a slurry facade and therefore will reduce human casualties and other damages caused by the collapse of the facade.

By creating a distance that the exterior surface of the facade creates with the main body of the building, while the presence of air in this distance will play the role of sound and thermal insulation, it can be done with calculations made to the construction site in terms of climate according to relevant standards (topic). 19 National Building Regulations of Iran) considered suitable thermal and acoustic insulation and easily installed, and even this space can be used to pass the system of mechanical and electrical installations.
