Ventilated facades as external finishing of buildings - this is the arrangement of a special hinged structure. Its fastening is carried out in various ways, which makes it possible to install individual elements on almost any surface. The ventilated facade has a number of advantages, and therefore is very popular both in industrial construction and in the private sector.
Design features
- Versatile application. Complex geometry of the base, its material are not obstacles to the device of the ventilated facade. This is especially convenient when, for certain reasons, it is not possible to produce the outer lining in traditional ways, or if it is associated with certain difficulties.
- No need to align the base. This is one of the main differences between ventfasadov from the usual crate. Saving time and effort is palpable.
- Variety of choice of the type of cladding.
- The presence of a gap between the surface and the finish excludes the appearance and development of putrefactive processes, since reliable natural ventilation prevents the formation of condensation.
- As a consequence - an increase in the life of all used materials, including walls.
- Possibility of additional insulation of the structure by any suitable material. If properly selected, the "dew point" will shift and will be located outside the building. In addition, the air layer itself reduces the heat loss of the structure.
- Thanks to the installation technology, the speed of production is increased.
- The cost of construction is sharply reduced due to a significant savings in finishing materials.
- High maintainability, the ability to eliminate the "local" defect as soon as possible.
- The installation work can be carried out regardless of the season and weather conditions.
Assembly steps
Preparatory activities
After dismantling the old lining and thoroughly cleaning the substrate, the entire surface to be finished is inspected. Detected defects( cracks, shells, presence of fungus) are subject to elimination.
After this, it is necessary to make sure that the wall is capable of withstanding the expected load( the total weight of the frame and all materials).To check, it is necessary to fix it on the basis of 2 - 3 dowels( in different places) and make sure that the fastener "sits" securely. On the basis of inspection, materials for finishing( including the type of insulation) are selected.
It is desirable to impregnate the substrate with anti-rot agents( antiseptics).If the structure of wood - in addition and fire retardants( from fire) - more about this you can read here.
surface layout The feature depends on the local conditions and capabilities of the host. It is better to use the laser level, this will provide an accurate "adjustment".If a cord is used, then it must be nylon, so that it does not form sagging when it is pulled. A thick fishing forest is also suitable for such purposes.
The markup starts at the bottom of the structure. The interval between the slats is selected in accordance with the dimensions of the lining products( boards, panels) and insulation.
Installing brackets and protective layers
The depth of the dowel socket should be slightly larger than its length, since during the installation it will collect all the dust from the walls and it will be rammed at the bottom. This can make it difficult to fully "land".
Mounting holders in this order: on the dowel - washer, under the fastener head - gasket( compensating for temperature deformation).
If necessary, waterproofing the substrate. Then - the material of the heater, which fits from the bottom up. Its fixation is made not only by gluing, but also by additional fastening with construction dowels( plate type).The wind-hydro-protective film( membrane) is laid on top, which is fastened with the same dowels.
Mounting of
guides They are racks, which form the supporting frame. How to properly install and fix them, is set out in the Installation Instructions. There is no single recommendation, since all elements can be executed in different ways( depending on the Producer).
The only condition - all the exterior surfaces of the slats should be in the same plane, otherwise the smoothness of the finish can not be achieved, as the facing plates( panels) will lie with a skew.
Fastening of "finishing" material
It can be either open( with the help of clamps), or hidden( invisible).Various products are used as facing: ceramic granite panels( 500-2,000 rubles / unit), composite( 1,200-1,400 rubles / unit), metal cassettes( 450 rubles / unit), and a number of other products( for example, fiber cement,glass pane).Each type of finishes has its own peculiarities of installation. Not all advertised facing materials are suitable for a private home, and this must be taken into account.
Do not use
- Place brackets in expansion joints, between bricks, slabs.
- Use guides for more than 1 floor of the building.
- When drilling holes in soft materials( for example, foam concrete), use the "drummer" function of an electric drill or perforator.
- Mount roll( film) materials "butt".They are stacked with overlap between adjacent bands( of the order of 10 cm).In this case, the seams are additionally sealed( with an adhesive mounting tape) to prevent penetration under the coating of the liquid.
Practical advice to
- The lack of appropriate Standards for the installation of ventilating facades is fraught with the fact that often perform such a job is taken by people with inadequate training. The matter is that for such installation, certificates, tolerances( in SRO) are not required. This is what some small "firmochki" use, which engage themselves as organizations that guarantee high quality. If the decision is made to conclude a contract, it is advisable to check the quality of the work that the firm has already completed. To see for yourself, to talk with the Owner, to ask his opinion. Subsequently, this will eliminate many troubles.
- In light of the foregoing, when hiring employees, one should first figure out all the subtleties of the installation process. This will provide an opportunity to monitor the quality of work at any stage and think about the advisability of further cooperation in case of "hack-work".And with the Executor - to collect, including, and through the court.
- Despite the attractiveness of equipping the ventfasade, it is necessary to take into account the type and condition of the foundation. Is he able to withstand the weight of such a design?
