Construction technology of ventilated facades appeared in Russia recently, but managed to gain popularity and wide use in construction.They have excellent technical and functional characteristics.They are used in the construction of both new and repaired buildings.Designed ventilated facades can be in homes, industrial facilities, public buildings.Preferred features are: quick and easy installation that does not require removal of defects and leveling the surface, durability (depending on the material service life is about 25-50 years), the variety in the choice of cladding materials, insulation and building insulation, environmentally friendly, fire resistance,a quick repair of individual sections of the facade.

ventilated facades Ventilated facades are designed for architectural design and efficient insulation of buildings.Plans by construction facade is a multilayered structure of the coating materials, mounted on metal carrying frame.Substructure is mounted so that between the wall and facing the air gap remains, which serves to remove excess moisture and steam.As cladding materials are: the front panels and sheets, sandwich panels, metallokassety, ceramic, composite materials, polymer coating texture, etc.Metal lath may be made of galvanized or stainless steel, aluminum.
For additional insulation of ventilated facades between the outer wall and the supporting substructure is mounted insulation that protects the wall from freezing and thawing.In addition, the heat insulating layer has zvukopoglaschayuschimi properties.
functions performed ventilated facades
air gap is a fundamental hallmark of construction technology of ventilated facade.Due to its excessive moisture inside the building is removed freely circulating air stream.Left gap and insulate layer reduces the likelihood teplonagruzki on building heat loss in a heated building period and overheating in the summer.These advantages reduce the cost of thermal energy for heating the building.
distribution function cladding material and supporting framework to help protect the building from adverse environmental effects that can significantly increase the life of the building.
Ventilated Facades meet all the requirements of fire safety, asused finishing materials, mineral wool insulation and fasteners are non-combustible materials.
Installation of ventilated facades
One of the main advantages of ventilated structures is a quick and easy installation.In addition, installation is permitted throughout the year and in sub-zero temperatures.Qualitatively made and installed a system of ventilated facades extend the life and protect the building from the effects of the environment.
substructure system consists of several elements: monolithic or retractable bracket, insulation, vertical and horizontal-vertical guides, fasteners.
Technology installation of ventilated facade is divided into several stages: design and preparation of the building to the warming, development of schemes supporting structure and layout of the facade, mounting brackets, insulation and windproof film mounting rails, installation of cladding material.
To begin the installation of ventilated facade follows a study of the whole project documentation and in accordance with the installation instructions.During the study, the object is carried out surveying the building and heating engineering calculations, during which clarified the actual size, condition, type and load capacity of the outer walls of buildings.Based on these data, a draft mount type and thickness of the thermal insulation facade.Using the obtained calculation circuit composed support structure, followed by counting the facade and fixing points.Marking as installation of all ventilated facade, made from the bottom up.
Scope of ventilated facades and mounting method
ventilated facade cladding systems are designed for buildings: sandwich panels, granite, metallokassetami, cassettes of composite material, natural stone, fiber-cement plates, floorings, siding, etc.The materials used must meet all the standards, quality and technical requirements, conform to a particular project and intended for ventilated facades.
One of the main elements of the substructure is an anchor providing mounting brackets to the wall.The diameter of the anchor and the depth of his attachment selected taking into account the load acting on the bracket.The length of the bracket for ventilated façade is selected according to the thickness of insulation.The number of brackets per 1m2 determined by statistical calculation based on: maximum permissible load of the outer wall and bracket weight of coating materials.
Fixing thermal insulation boards made at Belleville dowels, which are stacked in staggered rows close to each other.Insulation on the outside of closed windproof film overlap of 10-15 cm. The distance between the insulation and the facing material should be greater than 20 mm, but the reduction of airspace may be no more than 5 mm.
After installing the insulation layer and windproof film mounted rails.The guides are mounted on brackets through the slots carved into the shelves of the carrier profile for ventilated facade.Their vertical plane aligned and secured to the brackets, the excess is bent or cut.At the junction of the two guides it is recommended to leave a hole of 10 mm.Corner units are attached to the rails by means of angular plates.
Door and window panes are installed in accordance with the project.The side, top and bottom soffit attached to the vertical guide bearing frame in increments of not less than 400 mm.Elements of a frame are compiled into a single box at the factory, or directly to the installation of the facade.
lining ventilated facades Installation of porcelain stoneware slabs
One of the most popular is the ventilated facade of porcelain stoneware materials.
distinctive feature of the installation is the use of porcelain stoneware slabs of metal profiles - capping.Mounting plates begins to set on a horizontal line starting capping, which fastens granite.Plates fixed ordinary clamps, 2 cm above the plate.Leave a gap of 2 mm between the pilot, private, end capping and granite.Installation of granite cladding made from the bottom up, from left to right.
Installation of ventilated facades lining composite
widespread ventilated facades made of composite materials.This material is made of sheet metal and mineral composition, it has high strength and resistance to external environment, withstands temperatures from -500 C to +800 C.
Installation of composite tape in two ways: on the corners or iklyah and sled,studs on the guide.Corners are established by means of rivets, and then attached to the cassette guide.In the second case, the objectives of the wall studs and runners hung composite tape and then fixed with rivets.
What determines the cost of installation and the cost of ventilated facades Installation of ventilated
construction takes an average of 10 days to one month.It is not recommended to carry out installation work in rain, fog or below the permissible ambient temperature on the safety requirements.Before starting the installation, you must install the roof of the building.To protect the surface of the lining is not recommended to install it any extraneous elements.
cost of ventilated facades depends on the size of the building, facing selected, fasteners, of insulation and bearing materials.The cost of installation of ventilated facades constructed from several components: the selected Matera facing facade and complexity of the device.Engineering design and installation of complex engineering systems should be performed by qualified personnel, taking into account all the nuances, regulations and requirements.Errors in the design and mounting, can lead to serious consequences.
