Installation of hinged ventilated facades

The technology for the construction of ventilated facades in Russia appeared relatively recently, but managed to gain popularity and widespread use in construction. They have excellent technical and functional characteristics. They are used both in the construction of new and repaired buildings. Ventilated facades in houses, industrial facilities, and public buildings can be designed. The predominant characteristics are: simple and rapid installation that does not require elimination of defects and alignment of the surface, the durability of the design (depending on the selected material, the service life is about 25-50 years), the variety in the choice of facing materials, thermal insulation and noise insulation of the building, environmentally friendliness, fire resistance, The ability to quickly repair individual sections of the facade.

Properties of ventilated facades

The hinged ventilated facades are designed for architectural design and effective insulation of buildings. According to the construction technology, the facade represents a multilayer design of facing materials fixed to the supporting metal frame. The fitting structure is attached in such a way that an air gap remains between the wall and the cladding, which serves to eliminate excess moisture and steam. The facing materials are: facade panels and sheets, sandwich panels, metal cassettes, porcelain tiles, composite materials, polymer texture coatings, etc. A metal crate can be made of galvanized or stainless steel, aluminum.

For additional insulation of ventilated facades, thermal insulation is attached to the wall that protects the wall from freezing and thawing. In addition, the heat -insulating layer has soundbreaking properties.

Functions performed by ventilated facades

The air gap is a fundamental distinctive feature of the technology for the construction of a ventilated facade. Due to it, excessive internal moisture of the building is freely removed by circulating air stream. The abandoned gap and insulation layer reduces the likelihood of heat load on the building, heat loss in the heated period and overheating of the building in the summer of the year. These advantages reduce thermal energy costs for heating the building.

The distribution functions of the facing material and the supporting frame allow you to protect the building from adverse environmental influences, which can significantly increase the life of the building.

Ventilated facades meet all fire safety requirements, because The finishing materials used, mineral wool insulation and fasteners belong to non -combustible materials.

Installation of hinged ventilated facades

One of the main advantages of ventilated structures is quick and simple installation. In addition, installation is allowed throughout the year and at minus temperatures. A qualitatively executed and mounted system of hinged ventilated facades will extend the service life and protect the building from environmental influences.

The plain system consists of several elements: a monolithic or retractable bracket, insulation, vertical and horizontal-vertical guides, fasteners.

The installation technology of the ventilated facade is divided into several basic stages: design and preparation of the building for insulation, development of a circuit of the supporting structure and the facade marking, fastening brackets, insulation and windproof film, fastening of guides, and installing facing material.

You should proceed to the device of the ventilated facade after studying the entire design documentation and according to the installation instructions. During the study of the object, a geodetic survey of the building and thermotechnical calculations are carried out, during which the real dimensions, condition, type and allowable load of the external wall of the construction are clarified. Based on the data obtained, a mounting project is developed, the type and thickness of the thermal insulation of the facade is developed. Using the calculations received, a circuit is drawn up, after which the facade and fastening points are marking. Marking, as well as the installation of the entire ventilated facade, is carried out in the direction from the bottom up.

The scope of ventilated facades and the method of fastening

Ventilated facade systems are designed for facing facilities: sandwich panels, porcelain tiles, metal cassettes, cassettes from composite material, natural stone, fiber cement slabs, corrugated board, siding, etc. The materials used must meet all standards, quality and technical requirements, meet a specific project and is intended for ventilated facades.

One of the main elements of the plain structure is an anchor mount that ensures the mounting of the brackets to the wall. The diameter of the anchor mount and the depth of its fastening are selected taking into account the load acting on the bracket. The length of the bracket for the ventilated facade is selected in accordance with the thickness of the insulation. The number of brackets for 1m2 is determined by statistical calculation, taking into account: maximum permissible load of the outer wall and bracket, mass facing materials.

The heat -insulating plates are mounted on plastic dowels, which are stacked in a checkerboard pattern close to each other. The insulation on the outer side is closed by a windproof film, an overwhelming 10-15 cm. The distance between thermal insulation and facing material should be more than 20 mm, but a reduction in airspace is allowed by no more than 5 mm.

After installing the insulation layer and windproof film, guides are mounted. The guides are installed on the brackets through the grooves, cut down in the shelves of the supporting profile for the ventilated facade. Their vertical plane is aligned and fixed to the brackets, the excesses of which are bent or cut off. At the junction of the two guides, it is recommended to leave a hole of 10 mm. The corner elements are attached to the guides using corner plates.

Door and window castings are installed in accordance with the project. The side, upper and lower slopes of the opening are attached to the vertical guides of the supporting frame, with a step of at least 400 mm. The framing elements are compiled in a single box in the factory, or directly when installing the facade.

Installation of faces of ventilated facades from porcelain stoves

One of the most popular is the ventilated facade of porcelain materials.

A distinctive feature of the installation of porcelain stoves is the use of metal religious core profiles. Mounting plates begins with the starting line of the starting Klyammers installed on the horizontal line, on which porcelain tiles are attached. The plates are fixed with ordinary Klyammers, 2 cm above the plate itself. A 2 mm gap is left between the starting, ordinary, end Klyammers and porcelain tiles. Installation of porcelain cladding is carried out from the bottom up, left to the right.

Installation of ventilated facades from composite materials

Ventilated facades from composite materials are widely used. This material, made of metal sheets and mineral composition, has high strength and resistance to external environment, withstands a temperature from -500 C to +800 C.

The installation of composite cassettes is carried out in two ways: on the corners or icls and sleds attached to the guides. The corners are installed using rivets, after which the cassette is attached to the guides. In the second case, a composite cassette is hung on the rivets and slide fixed in the wall, then it is fixed using rivets.

What depends on the cost of installation and the cost of the ventilated facade

Installation of a ventilated structure takes an average of 10 days to one month. It is not recommended to carry out installation work during the rain, thick fog or outdoor temperature below permissible according to the requirements of labor safety. Before starting installation, it is necessary to install the roof of the building. To protect the facing surface, it is not recommended to mount any extraneous elements into it.

The cost of ventilated facades depends on the size of the building, selected facing, fasteners, insulation and supporting materials. The cost of installing ventilated facades is built from several components: the selected facing material and the complexity of the facade. Technical design and installation of this complex engineering system should be carried out by qualified specialists, taking into account all the nuances, instructions and requirements. Errors made during design and mount can lead to serious consequences.
