Introducing a variety of wet and dry Facade
Due to the industrialization of all walks of life in today’s world and the sensitivity to saving time, cost and accuracy in
execution, the construction industry has also changed and is moving towards industrialization. It is very receptive, if
the various departments and the engineering community can support the dry method, we will achieve very good
results in the construction sector.
The steps for implementing a dry façade are as follows
L-shaped plates are installed along each other on the wall of the building.
- Install insulation board on the wall of the building
- Vertical carrier profiles are installed on L-shaped plates using rivets.
- The dry facade used is placed in aluminum frames and is sealed on all four sides
-The dry facade used is strengthened according to the type of connection with the building body
Advantages and features of dry façade method:

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.

Technical specifications of dry brick façade
Superior and different thinking
Jourchin company is proud to combine the valuable experiences of past architects with modern technology and has made it possible to implement bricks in a dry manner. The design method of execution is such that it is completely project – oriented and any type of architectural structure with different layouts and different brick dimensions, considering that the façade of the building is facing the atmospheric factors, the executed façade is resistant to these factors. It also has the necessary beauty and is in harmony the façade of the adjacent buildings. It is designed and implemented by the company’s experienced engineers. In this method, while facilitating the execution method, most of the disadvantages of brick execution have been eliminated in the form of mortar.
Integrity and high resistance
In this method, a high strength integrated shell is created using a façade retaining structure that is responsible for bearing the load and connecting the shell to the building structure, as well as special fittings that are responsible for maintaining the brick. The structure of this complex is designed in such a way that while it is firmly connected to the skeleton of the building, it will show resistance to earthquakes in a completely separate way and the shell will integrate the movements caused by the earthquake in an integrated way.
Components of dry brick façade
Shell – bearing structure
In all methods of applying dry faced, the shell – bearing structure which is responsible for bearing the load and connecting the shell façade to the building structure, is of particular importance. These structures are usually made of iron profiles, but due to the use of welded joints, they don’t have proper strength.
The structures designed by jourchin company are bolted in this way, in each project, the relevant calculations are performed separately and a special structure for the same project is constructed. The structure of this complex is designed in such a way that while it is firmly connected to the building, it will show resistance to the earthquake completely separately and the shell will completely dissipate the movements caused by the earthquake.
Brick fittings and rails
Brick retaining joints are attached to the retaining structure and are designed in different projects according to the different methods of brick arrangement. These joints are made of galvanized sheets and their thickness will vary according to the calculations performed. They are also resistant to decay transfer a small amount of weight to the structure.
In order to prevent the earthquake forces from being installed on the brick parts, shock absorbing rubbers that are resistant to different climatic conditions have been installed at the connection of the brick with the rails, which will reduce the pressure on the brick and prevent. It from breaking and it also fixes the brick to the rail.
Special brick for dry façade
The bricks that will be used as the final coverage are designed in full detail and have special physical characteristics.
By researching the types of bricks, the best option with maximum resistance to breakage and minimum water absorption capacity is refractory brick.
Below the picture, the façade of the building on the ground floor is mortar and dandruff, but the dry floor façade is without dandruff

Final installation of bricks and their fixing is designed with rubber bands.
Final binding with a variety of sand and cement (traditional method), resin mastic.
The projects that will be targeted by this production process are as follows
The huge projects that the group of consultants and with special and defined investments is leading both In the private sector and in the public sector, which will certainly be the focus of the project – oriented project and will not be public?
Buildings that are designed and executed as indicators by special designers and architects in the form of a permanent building and a work, and the type of use are mostly residential or office. This group is important in terms of quality design and small in number, and this category of buildings will also be project – oriented.
Quite special projects the scope and amount of investment in the building are not particularly important. Like projects in the field of cultural heritage and restoration, which can be boldly implemented in accordance in such projects, and certainly such buildings will be in the line of the project – oriented.
Small buildings that are invested in the private sector in all cities of Iran and have a significant amount. In other words, buildings with low infrastructure in a limited number of floors, which are a kind of model of such a building, and this will be one of the important and extensive goals of the project.
According to the detailed study of the no.714 criterion, which includes structural design instructions, requirements, functional criteria and implementation exterior facades of buildings, as well as providing appropriate solutions, to prevent the impact of seismic loads, wind, impact and other environmental factors and control them.
Therefore, the instructions and details in this regulation of the road, housing and urban research center, the requirements for the basic and technical implementation of brick stile in towers are not provided as mortar and the mortar used is only used to connect bricks in a stacked state and connect shell 10 cm is recommended by dry connections to the structure or carrier wall and for the implementation of mortar brick tile the emphasis is on locks and attachment to the structure and the implementation of methods to control it.
Also, according to the above – mentioned cases, it is necessary to mention that in the brick mortar façade:
– It’s execution speed is low.
– It’s weight twice as much as dry facades.
– In some cases, we see dandruff.
– It is not resistant to earthquakes.
Due to the high price of stone and the load that stone imposes on the building, in some countries, the use of ceramics
as a facade of the building has become quite popular. Ceramic facade weighs less than stone. Ceramic facades are
divided into two categories:
– Restrained or dry ceramic facade including porcelain ceramic facade and ventilated ceramic facade
– Attached ceramic facade
The term porcelain refers to a wide range of ceramic products that have a high firing temperature. The reason for
baking porcelain at high temperatures is the nature of glass, as well as low porosity in porcelain. Dry porcelain
ceramic facade is one of the most up-to-date building facades in the world, which is executed by dry installation
method. Dry porcelain ceramic is the dry facade covering, which is the most important part of this type of facade and
should have sufficient strength in a single module and the lowest possible water absorption. Dry porcelain ceramic
facade is commonly used for various commercial, office, residential as well as interior parts of buildings, terminals
and metro stations, etc.
Dry porcelain ceramics produced for facades are offered in two general forms in the market of the country’s
construction industry, which include hollow porcelain ceramics and full-porcelain ceramics, which are also called onecentimeter ceramics or full-blown ceramics.
Properties of dry hollow porcelain ceramics:
Dry porcelain ceramics with holes in its thickness have more insulation advantages - have. Because the air in the empty cavities prevents cold or hot air from penetrating through the ceramic body They play the role of insulation in the thickness of dry porcelain ceramics
Due to the holes in the ceramic body, a significant percentage of the volume of this ceramic will include air. This reduces the weight of the dry façade.
This type of ceramic with the installation of the palate and tongue in both the upper and lower sides, issues related to sealing the seam Horizontal dry porcelain ceramic facade is dissolved 100% so that air passes behind them, but water and moisture do not penetrate behind them in any way
This type of dry porcelain ceramic has special parts for corners, window floors and flushings. It is a building that gives great elegance to the finished facade and gives the product high adjustment and sealing ability.
he cost price of this product due to the use of high technology of its production, which is of ceramic type Extrudes with a special shape are considered to be more.
Features of dry porcelain ceramic - one centimeter
These ceramics have most of the properties of dry porcelain ceramics, which is the same as low water absorption.
The standard dimensions produced for this type of dry porcelain ceramic are 120 * 60 and can be cut to It has the desired dimensions of the design
Most executive details related to dry porcelain ceramic, both visually and invisibly It is also possible for this type of dry porcelain ceramic.
Special executive systems for installing this ceramic in terms of being visible or invisible Its design and parts have been produced, which has all the world standards.
The cost price of this product is lower than dry porcelain ceramic

Installation method with clips and horizontal rails :
Execution systems of solid dry porcelain ceramic facade - one centimeter
In this method, dry porcelain ceramic tiles are connected to the substructure aluminum rails at specified intervals by stainless steel clipless parts. The color of the clips is electrostatically matched to the selected ceramic color by the polyester color, and high-quality EPDM rubbers are placed at the junction of the ceramic to the rail to prevent the ceramics from slipping.
Kail system fittings are, in fact, hidden mechanical joints without the need for glue, which have been created to cover the facade with a variety of materials. This system is widely used in the construction industry to cover facades, interior and exterior walls and even roof surfaces (exposed to rain). In this method, like the previous method, the clips and the ceramic holder will not be visible, the method and the keel system are done using the undercut machine. In this method, special anchors are installed inside the ceramic, which requires an undercut machine to create a hole. The undercut machine creates a puffy cross section so that the anchor is inserted into the ceramic and its blades open in the created space.
In this method, grooves are first installed on the back of the ceramics by an automatic grooving machine. Special grooves are made in two opposite directions and then the clamps are completely tightened by the special adhesive inside these grooves due to their protrusions. The ceramics are then placed on the rail through the clamp and regulated in place by a screw installed on the clamp. Dry facade performance requirements must be fully implemented and no items related to materials and infrastructure should be omitted, as the slightest shortcoming will cause the greatest damage.
