Cassette hinged ventilated facade (HVF)

The design of a cassette aluminium ventilated facade consists of a protectively-decorative facing part which is mounted on some distance from a wall. The air interval allows to lift considerably protective properties of all system where the special warmly isolating covering  of building object enters also.

Usually facing of cassette aluminium ventilated facades carry out from the aluminium composit panel or aluminium monosheet. Application of front aluminium allows to lower cost of aluminium designs of a facade several times. It reduces cost of a hinged facade. Besides aluminium application, in designs of a cassette aluminium hinged facade, allows to create the difficult architectural forms inaccessible at application of "stone". All these factors lead to that the part of cassette facades with facing of  aluminium materials grows and will grow in the future . The design of cartridges of  a composite consists of four basic parts:

 1. A heater
 2. Protection against the wind
 3. A fixing subsystem
 4. Cassettes

A heater

It joins an external wall. It is made of ecologically pure mineral fibre (fibration of structure provides sound insulation). Heater plates consist of two parts: the first part is soft, adjoins directly to the wall surface, the second part is external, more dense and steady. Protective feature of a heater consists that it covers all surface of a wall, saving thus a premise from a frost and a condensate which increases building service.

Protection against the  wind

The heater is protected by a membrane from influence of streams of air. The membrane carries out two basic functions:
Humidity regulation. The moisture from building walls through a membrane leaves from a facade an ascending stream of air. Thus, the atmospheric moisture does not get in a heater.
Protective function. The membrane protects mineral cotton wool of a heater from aeration.

Fixing subsystem

The design represents set of arms and directing, fixed on a wall. Aluminium arms are passed through a layer of a heater and are responsible for distance adjustment between a wall and directing. Directing represent aluminium profiles on which facing panels are fasten.
At correct assemblage and successfully chosen fixing system the cassette hinged ventilated facade provides uniform loading on a wall, not causing mechanical deformations of a design, and also a different sort of thermal deformations. Systems of aluminium cassette hinged facades possess possibility of regulation of distances between a wall and external facing.

Cassettes

The external surface of an aluminium facade should represent a plane close to ideally equal. Therefore aluminium cassettes is an important part of a facade. Aluminium cassettes should be by all means homogeneous for structure, rigid, easy and steady against climatic changes. The most various types of panels are used for facing in systems of hinged ventilated facades. Manufacturing of cartridges, as a rule, is carried out in the style which is in harmony with other elements of a facade: window apertures, doorways, a roof.

The basic advantages of cassette hinged ventilated aluminium facades  :
Attractive aluminium cassette facades.
One of the main advantages of cassette hinged facades of aluminium are boundless possibilities of a choice of modern front materials, formats and colours, the colour scale assumes various decisions for architectural registration of buildings.

Durability

The cassette aluminium hinged facade does not demand repair and does not lose the qualities for a long time. Aluminium front panels do not lose operational properties under the influence of a sunlight, deposits, an atmospheric dust, acids and salt suspensions for many years.
Protection of object against a moisture
Moisture accumulation in a building wall leads to its accelerated destruction as a result of repeatedly repeating cycle of freezing and thawing, essentially reduces heat insulation properties of a wall. Installation of a hinged ventilated cassette facade allows to solve cardinally the given problem as thanks to the features it reduces moisture content in a concrete wall. As a result the comfortable microclimate is formed indoors, there is no occurrence of fungi and a mould. On the other hand, there is no also an excessive dryness of air in premises.

Thermal protection improvement

The cassette aluminium hinged facade allows to improve indicators of a thermal protection of protecting designs considerably. The external thermal protection allows to strengthen warmly heat-sink ability of a file of a wall essentially. This advantage of an aluminium hinged cassette facade is widely used at reconstruction of the buildings which walls demand additional warming.

Sound insulation improvement

The cassette aluminium facade essentially raises sound-proof characteristics of a wall as front aluminium panels  and a thermal protection possess sound-proof properties in a wide range of frequencies.

Fire stability

There is difficultly combustible and nonflammable materials. The panels of facing made of sheet aluminium correspond to modern fire-prevention requirements. The cassette aluminium facade is recommended to application at facing of buildings with increased requirements of fire safety.

The minimum leaving while in service

Cassette aluminium ventilated facade are easily cleared of the dust which has settled on it and aggressive  water touches .

Ease of repair

The cassette hinged ventilated facade allows quickly, without dismantle of all design to carry out repairs and replacement of its separate parts. It considerably reduces the price and reduces volume of repair work. Especially it is actual in casual damage of a surface of a facade.

Installation of a cassette aluminium hinged ventilated facade :

1. Installation of arms;
2. Heater installation
3. Installation of the directing; 
4. Installation of facing cassettes
.

Installation of arms

For indemnification of roughnesses of a wall of a building are used power (for fastening in concrete) and intermediate (for fastening in cellular concrete) arms of various standard sizes. Arms allow to regulate horizontal and vertical alignment of a design, including indemnification of roughnesses of a surface of the basic wall.

Heater installation

After installation of arms is finished, before installation directing on a wall are established warmly insullated panels. To avoid freezing, panels should be cut out under the form of corners, deepenings, arms.
The surface warmly insulated panels is closed by a vlago-wind-shelter film. The thermal protection fixture on a facade is made according to recommendations of firms - suppliers and the design organisation.

Installation of the directing

The directing serve for fastening on them of front cartridges. The vertical row of the directing is mounted, starting the bottom section.

Connection directing on a vertical is made on a power arm. Thus the bottom directing fastens on an arm rigidly, on two bolts, and top - on a rivet in an oval aperture on an arm that allows directing to be extended and shortened at change of air temperature.

Installation of cassettes

After installation on a heater and skeleton facade from below installation of hinged aluminium cassettes upwards is made. Thus the sizes of cassettes and appearance of a facade are defined according to the task for an architectural part of the project of the facade.
The bottom part of the cassette is put in the lock with the top part of the bottom cassette, and the top part fastens exhaust rivets or self-cut screws to the directing.
