Installation of a ventilated facade made of porcelain stoneware: technological map, recommendations for installation. For decades, civil engineers have tried to find the natural and most effective way to remove excess moisture from building walls.
This is how ventilated facades of porcelain stoneware were developed - the latest technology of arrangement involves performing a complex complex of construction and installation works step by step. Let's try to figure out all the complexities and subtleties of technology.
Porcelain stoneware ventilated facade is a complex system.
As practice shows, we can conclude that the durability of the building in the future will depend on how correctly the facade installation technology is followed and implemented.
Important! Errors and non-observance of technology will manifest themselves already in the first years of using the building. Often, such errors are reflected in the incorrect operation of the ventilated facade system, and lead it first to a partial, and then to a complete failure.
Installation technology of a ventilated facade made of porcelain stoneware
As it was already correctly noted, the facade is ventilated, which means that it is a complex system. Because of this, engineers have developed a list of preparatory measures that should be performed in a strict order.
It was even approved at the level of legislation and recorded in SNiP 3. 01. 01-85 "Organization of construction production".
Please note that it is strictly forbidden to install the façade in low temperatures or strong winds!
You should also take care of safety of people, and for this you need:
It is clear that such nuances are mostly related to multi-storey construction. But if you decide to create such a system in a country house with your own hands, but it will be superfluous to adhere to all the rules and regulations in order to protect yourself and the residents from force majeure.
Before starting the installation of the facade made of porcelain stoneware, you should mark the points in those places where the bearing and support brackets for the ventilation system will be installed on the walls of the building.
Important! The marking should be done strictly according to the design and technical documentation, which was developed by experienced architectural engineers with an air gap.
The marking should be carried out in stages - first, define the lighthouse lines for marking, namely the lower horizontal and two extreme vertical lines.
Helpful Hint: Use a level to determine the extreme points. After the points have been marked with indelible paint, the intermediate notches should be noted on which the brackets will be installed in the future. This requires a tape measure and a laser level.
Vertical lines can be easily marked if plumb lines are lowered from the parapet of the building.
According to the installation instructions, everything is clear, but pay special attention to fastening the brackets:
At this stage it is planned to perform the following works:
There are at least 2 dowels per slab.
They require the installation of disc dowels. Install insulation boards starting from the bottom row. Important! Insulation boards should be installed on the base or starting profile in advance. After installation, it should be done from the bottom up.
Now let's move on to the next step - installing the guides.
Vertical guide profiles should be attached to the brackets that are adjustable, and for this you need:
8 to 1 cm should be left. This will make it possible to exclude deformation due to temperature and humidity fluctuations.
And let's go to the last step.
The arrangement of cladding is difficult to describe, and it will be much more useful and informative if you watch video .
Separately, I would like to talk about the most common errors that occur in the process:
This will create cold bridges, which will significantly reduce the effectiveness of thermal insulation.
Try to avoid such mistakes, and then the result will definitely please you for a long time.
Before choosing the type of work on the installation of a ventilated facade made of porcelain stoneware, the following factors should be taken into account:
The supporting elements of the frame must be made only of metal, otherwise currents will appear at the contact points, which accelerate corrosion. You should never skimp on the strength of the brackets, you should only buy the best and most reliable.
Porcelain stoneware is quite heavy, don't forget about it.
Conduct construction work only in good weather, if it is likely that it will rain - try to protect the structure from water ingress. The manufacturer says that it is possible to install structures only at an air temperature that is at least -15 degrees, but it is better not to do this. The point is not that the structures can not withstand, but that it is difficult to work in cold weather.
As a result, the technology may be violated, errors will appear when marking or installing elements.
In addition, the snow that falls on the mineral wool will melt, and with an increase in the material's moisture content by only 5%, the thermal conductivity will increase by 50%.
For porcelain stoneware slabs, it is imperative to install horizontal and vertical support profiles. Thanks to the combined frame, the bending load will be evenly distributed. So the structure will become durable and reliable. If the strength of fixation of the vertical profile is violated, the horizontal one will withstand the load or vice versa.
The disadvantage of such a system is the increased cost, but it is better not to skimp on security.
Also carefully install the frames and abutments, the side ends should be covered only with solid plates. Assign an important role to the plinth and places that are adjacent to the roof. Try to exclude moisture, but the ventilation does not need to be closed.
