The present invention discloses an insulation system that is installed outside of buildings non-industrial, industrial stone wall or brick or massive or light structures made of concrete or wood frame.

It comes to thermal and/or acoustic insulation of facades of buildings that may contain many stories.

In a first known system, the insulation consists of a rigid mineral fibre panels, mostly made of mineral wool or of an organic foam material, mostly made of foam.

These panels are glued to the outer wall of the building, subject isolation, and they basically allowed the mechanical elements of the point deduction type dowel-nail, able to expand especially for walls of great height or in areas exposed to strong winds.

Insulation panels are then covered with decorative organic or mineral coating, often reinforced by a grid of deliciousdelicious fiberglass.

In this system the panel must be rigid, as they give the mechanical properties of the cladding. Permissible resistance to the force of pressure/dilution arising from the wind, is achieved by gluing and mechanical means of retention. The surface, though, is prone to damage p�d by the action of pressure and shock in the collision with foreign bodies on surface finishing coating layer.

In addition, the disadvantage of the panels of the organic foam material is that they are relatively impermeable to water vapor and does not allow, therefore, water vapor effectively to seep through the wall.

In General, the mounting adhesive has a drawback when you upgrade, so it requires a wall, a planar defect which is less than a few mm per meter. In this case, when the surface is subject to isolation, significantly damaged, the necessary preliminary repair, what is spent on time and materials.

In another known system, the insulation is enclosed between the elements of the frame fixed on the wall, subject isolation, which can be wooden or metal, and the front side are connected through the supporting structure, forming on the rear face side of the space, inside of which lies a layer of air associated with the external environment.

This design avoids the risks of condensation and accumulation of moisture on the facade, causing a decrease in thermal insulation properties, favoring the rapid spread of microorganisms, algae and fungi. This is especially true timber frame, as the tree is at risk of destruction under the influence of humidity.

The disadvantage of ventilated facades is the complexity of their installation, in particular for single point level (doors, Windows...). Moreover, in the event of a fire the ventilation of the facade contributes to the spread of fire to upper floors (the effect of upward flow).

In the majority of ventilated facades to retain all of the complex framework of using paws or other metal accessories (galvanized steel or aluminum). These accessories contribute to the mechanical resistance of the facade, and their number is mainly determined depending on various conditions of the external loads to which they are subjected.

The aim of the present invention is the study of new solutions for installation, which will improve the energy properties of complete facades.

Thus, according to the inventors, these legs are a disadvantage which consists in the formation on the facade of thermal bridges, the effect of which may be so significant that they can cause the insulation losses of 15 to 30% by considering thermal resistance. Today, the market does not exist mechanically stable fixing feet for facades of buildings, easy to apply, which are, above all, fire-resistant and which can effectively reduce the negative impact of the frame associated with the facade on the isolation level.

Thus, the aim of the invention is an exterior insulation system, the mount on which the FAS�de is reliable and fast, in particular without the need for gluing insulating elements.

The invention also aims to develop a compact and lightweight exterior insulation system, which will facilitate its fastening to a wall and will give the opportunity to transport it in such a compact form as a roll. This system can be installed on walls with irregularities on a large part of the surface up to a few centimeters, without having to first repair the walls.

And finally, this outer insulating system allows you to dry the structure in the inner and outer parts, that is, respectively, the natural tendency of the stone walls to absorb and release moisture depending on the season without the need for the air gap (compact system). This latter feature, in combination with mineral wool reduces the spread of fire in case of fire on the façade and guarantees a good resistance to fire.

All these objectives are achieved by the present invention, the object of which is exterior insulation system of buildings, comprising: insulating elements, covered with finishing plates supported on a set of profiles installed on subject isolation wall,

characterized in that the insulating elements and are held consoles, with�eraseme substantially flat first part for supporting and fixing on wall, subject isolation, and a substantially flat second part of the support, retention and mounting on a regulated specified distance from the wall to the first substantially flat part of the profiles that contain the second substantially flat part of the support for finishing plates, and the console is made of a material with a thermal conductivity not exceeding 0.5 B/(m·K).

This system is notable for the fact that console in addition to their mechanical properties have properties of thermal bridge rupture implemented through a composite material with a thermal conductivity lower than 0.5 B/M. K.

It also meets the requirement of energy efficiency, having the advantages of a logistical or operational simplification, as it does not require additional parts to implement the new feature.

thermal conductivity of the material of consoles, in particular equal to at least 0.1 V/(m·K).

This system mounts on the frame did not require glue. It is particularly effective when using the insulating elements on the base insulating wool is able to absorb moisture, and then to give it when the seasons change without affecting its essence and integrity. We can talk about mineral, organic or vegetable fiber, natural or synthetic, in particular about the fiberglass, mineral wool, PE�icofom fiber, wood fiber, flax fiber, cellulose wadding. It should be noted that for the system are also suitable cellular or foamed insulation materials, such as organic or mineral foams, foamed or extruded polystyrene, polyurethane, polyisocyanate, phenolic foams, glass wool.

This system is also compact, since finishing plate can be fixed to the profiles without an air layer in the system.

Can be used insulating fiber of relatively small volumetric weight, preferably glass wool, as will be shown in detail hereinafter. This insulating fiber is available in compact form, easy to transport roll. Moreover, this insulation is not rigid, but rather compressible, which allows easy installation of wires, conduits, cables, pipes or sewer systems in the insulating material. Once the roll is expanded, insulating fiber may be positioned in the form of a panel.

Face plates also is available in a reduced size, for example 2500×1200×12.5 mm, this size, they are also easy to transport.

For the purposes of the invention, the term "console" refers to a medium capable of mechanical stability of the frame of the facade of a duration of ten years.

To�ncol needs to provide rigidity and mechanical resistance, sufficient to withstand the weight of the frame, to resist the cycle pressure/weakening of the wind, and is manifested in case of need, the maximum acceptable deformation of the components of the facade (extension, tremors). According to the present invention they can be made of reinforced plastic material, or equivalent, preferably even fire resistant.

For the purposes of the invention, the term "held" means, as usual, "which are secured by or through", but also in an extended sense "held in place by means of". It is being applied to the profiles that are in mechanical communication with consoles and insulating elements which come into contact with the consoles, the position of which is limited to the last on each side.

The profiles that form the backbone of the facade, held consoles. They can be made of metal, reinforced plastic or wood.

And although the insulation system according to the present invention is preferably devoid of an air layer, while finishing plate components and finishes which they are covered, should be permeable to moisture, the presence of a layer of air is not beyond the scope of the present invention.

In particular, it is convenient in accordance with this invention to secure the base por�Fili finishing plates on adjustable distance from the wall, subject isolation. Thus, it is easy to compensate for random surface irregularities of the wall.

In the case of ventilated facades is preferred vertical position profiles so that a layer of air passed across the facade between the profiles.

Specified substantially flat first part of the consoles, of course, designed to set that matches the creature with the flat wall surface to be insulating, in particular essentially in the vertical plane.

The second part of the consoles on which are mounted the profiles installed in any plane that is not parallel to the wall to be isolated, preferably essentially in the perpendicular plane. She, in particular, can be horizontal and to serve, therefore, to maintain insulating fibers, which avoids fixing dowel-nail and thus reduce the cost of installation. In any case, preferably it is set vertically.

The first part of the profiles, thus conveniently establish partially coincident with the second vertical part of the console on which it is forced to slide until it reaches the desired distance from the wall and perform the mount by any means.

Any mount, considered here, whether it is:

- mount con�Oli to the wall, subject isolation, or

profiles to consoles, or

- finishing plates to the profiles,

it is done by screws or equivalent fasteners (rivets, cotters), in particular in the first case with the dowel, put into the wall.

In accordance with the above console preferably have an essentially L - shaped.

Preferably, brackets contain amplification of connection between said first flat part and the second part. The purpose of this strengthening is to ensure long-lasting sustain and retain vertical or lateral loads, formed by the insulation system.

According to the first embodiment of this gain consists of the third flat portion connecting said first and second parts and divide them into two segments of parallel straight lines.

According to the second method is the increase consists of a third flat portion perpendicular to the specified first and second parts.

According to the third method, the reinforcement is to add material, i.e. thickening, localized at the junction or intersection of these first and second flat parts. In particular, in the case of L-shaped console, the thickening may be formed at the corner portion due to the fact that the thickness of the part, following along the bisector of the angle, is greater than the thickness of each PL�tion parts on both sides of the angle.

Preferably the second part of the console bifurcated to form a slot, designed to position it at least one portion of a limb of the first part profiles. This bifurcated portion of the console can be pre-drilled twice for receiving attachment means of the profile, such as a bolt or equivalent means. It can also be formed so that will compress part of the profile, is inserted into the slot. To this end the width of the slot may be slightly above (about several millimeters) thickness of the first part of the profile, designed for positioning in the slots. Maximum side clearance of 1 to 2 tens of millimeters on both sides of the profile in the slot it is sufficient to insert the profile and adjust its position. This gap is preferably reduced to zero at the level of the free edge of the console for the implementation of the above compression.

In the particular case, the entire flat portion of the console has the shape of a forked end of the plate.

This slot preferably describes the symmetry of the free end of the second part of the console. This option guarantees the best mechanical properties.

Mounting profiles to consoles is mostly carried out through three holes formed in a line and respectively in two of the walls indicated the PoWPA�and on the one hand, and the specified first part of the profiles on the other hand, in calling the fastening elements (screws, dowels). This system provides a more secure attachment.

Preferably, the console according to the present invention has a minimum shear strength (characterizing in the prescribed position, the resistance to vertical load on the console) to 700 N, in particular from 800 to 1400 N and minimum tensile strength (in characterizing the prescribed position, the resistance force resulting from the force of the wind transferred from the façade to the console) in 2000 N, in particular from 3000 to 3500 N.

During the mechanical tests performed on a machine Instron 1185 at a speed of 4000 N/min, it was noted:

shift:

- with application of force of 730 N offset of less than 3 mm.

the shear force of 760 N corresponds to the displacement of 1.5 mm;

tensile: tear of the part during the application of force is not less than 4000 N.

According to the present invention the specified console is made of a material with a thermal conductivity not exceeding 0.5 V/(m·K). They thus form an effective thermal bridge breakers between the wall subject isolation, and a new facade, an educated profiles and decorative plates.

Preferably, the console is made of material that does not contribute to the spread of fire, and have exposure to the direct effects of fire for at least 5 min�t (without significant destruction after 5 minutes in the flame of a Bunsen burner). In case of fire, the temperature can vary from 20 to 1200°C for 10 minutes. Under these conditions, the console according to the present invention have a mechanical resistance of at least 15 minutes since the beginning of the fire.

The console remains in excellent condition after minutes of exposure to fire 30 kV (norm EN 13501), with no significant deterioration in the mechanical plan after 5 minutes.

The whole façade system (console+profiles+plate+plaster) have resistance to fire at least one hour.

The materials are preferably selected among an epoxy resin, a complex polyester, such as isophthalic polyester, vinyl ester, polyimide, phenolic, peek, polyaryletherketone, phenylene polysulfide, polyarylsulfone, polyethersulfone, silicone, phthalonitrile, individually or in various combinations with each other, and, in particular, with the input fibers, aramid or carbon, or also additives such as giving fire.

To perform these consoles these materials can be formed by extrusion, pultrusion process. These fibers are mechanically reinforce this material.

The console is fully made of plastic or polymer gives one detail mechanical and thermal (bridge the gap) properties.

It reduces the risk of corrosion at the level of the mounting bolts on the facade (in days�sensitivity, if the console is metal, the contact of two different metals can initiate and accelerate corrosion). According to a preferred embodiment of the present invention for bolts, you can choose any material.

In a preferred embodiment of the invention, the console has at least near one of its surfaces a structure with fibers oriented predominantly parallel to said surface, in particular originating from the Mat or sheath of fibers impregnated with synthetic polymers. These fiber length of at least several centimeters can be introduced into a composite material in the form of a shell or a Mat impregnated with identical pre-polymer or polymer different from the polymer used to manufacture the console. This structure is preferably present over the entire periphery of the part. With this arrangement, the console has a structure enclosed in the surface shell (at least partially), enabling the mechanical resistance of the consoles and, thus, the system, as well as their dimensional stability. Preferably this structure passes from one side of the console at a distance of 1/10 of the thickness of the respective flat parts.

The remainder of the console preferably reinforced mostly shorter fibers�, including fiber in the surface structure, usually the length of a few millimeters.

This console can be obtained by a pultrusion technique that allows you to enter in a die or Mat or any other form of two - or three-dimensional reinforcement, simultaneously with the filing in a die of a polymer or plastic compositions for impregnation or cladding one or more reinforcement members.

The size of the console is selected so that the console showed resistance to separation under the action of the strongest winds (2,1 kPa, ratio, including a safety factor of 1.75, with a maximum deformation of 3 mm) in accordance with the norm NV 65 (Eurocode wind) and the shift arising under the weight of the facade, up to 60 kg/m2the façade. Solutions according to the present invention have a weight of 18 kg/m2up to 30 kg/m2the façade. It should be clarified that the deformation resistance console defined above in relation to the weight of the façade surfaces loaded on one console (thus, the distribution of the consoles on the facade).

Insulating elements are preferably made on the basis of mineral fibers, which has a bulk weight of between 7 and 100 kg/m3in particular at most equal to 50 kg/m3in particular contained between 7 and 50 kg/m3or 7 and 40 kg/m3for example , about from 10 to 30 kg/m3. This product is �termicheski and acoustically insulating. As mentioned earlier, in addition it allows you to dry the structure, and is arranged to absorb and to some extent to give moisture without performing any actions.

Preferably, the insulating element has a thermal conductivity (Λ) of the order of 30-40 mW/(m·K), preferably from 30 to 35 mV/(m·K).

This product is lightweight, compressible and, in particular, transported in compact form (the rolls). Particularly preferred is a glass fiber.

Preferably, the profiles of the insulation system was T-shaped or L-shaped,

- part of the base which is designed to fix based on the flat part of the console on a regulated distance from the wall, subject isolation, and

the head part of which forms a flat support surface of the finishing plate, wherein the head part includes in particular one or two return wings.

T-shaped or L-shaped profile preferably contains one or two return to the wing so as to maintain an insulating fiber without having to use a dowel-nail.

The finishing plate is preferably chosen among gypsum boards, cement boards or flattened corrugated metal, metal grating, or an equivalent material covered in any case, a thick or thin layer ø�of glavki or thick or thin layer of sealer for gypsum or cement boards.

They constitute, for example, plates made of mineral material, resistant to moisture or adapted for use in a damp environment, in particular, relevant classification of H1. They, in particular, can be based binder with a water connection, such as gypsum or cement, and if necessary to contain impurities and/or reinforcement of synthetic material in the form of beads (polystyrene, expanded clay gravel...), fiber.

In accordance with preferred option embodiment of the invention they are formed mostly of light slabs, permeable to water vapor. For these purposes, can be used products on the basis of mineral materials, including gypsum. It is available in size 2500×1200×12,5, which, in particular, it is preferable to transport. Facade on finishing plate in a known manner to apply a base coat, reinforcing bars, coated with a finishing plaster.

Examples of products according to the present invention is available in the group Saint-Gobain (Saint-Gobain), it is, in particular, gypsum plates sold by the company Gyproc under the registered trademark GlasRoc, or cement slabs sold by the company Gyproc under the registered trademark Placocem.

According to another preferred variant of embodiment of a finishing plate obra�accepted the sheet of flattened corrugated metal, lined with a thick layer of putty (>10mm) two consecutive layers. An example of flattened corrugated metal is sold by Chabanne Bâtiment under the registered trademark Nerplac. A thick layer of sealer can be cement, and it is relatively breathable moisture as a result of its increased porosity.

On the other hand, the object of the present invention is the console that contains the first flat portion for supporting and fixing on wall, subject isolation, and perpendicular to the first part of the second flat portion of the support, the support and mounting on a regulated specified distance from the wall, and the console is essentially formed of a material having a thermal conductivity of at most equal to 0.5 V/(m·K).

According to other preferred characteristics of this console:

is formed from a material which does not support the fire and has exposure to the direct effects of fire for at least five minutes (significant mechanical damage missing when exposed to fire 30 kV at such length);

- made of polymers selected from among epoxy resins, polyesters, such as isophthalic polyester, vinyl ester, polyimide, phenolic, peek, polyaryletherketone, phenylene polysulfide, polyarylsulfone, polyethersulfone, silicone, phthalonitrile, individually or in various combinations with each other, and, in particular, with the input fibers, aramid or carbon fibers, or also additives that give fire resistance;

- it is made of polymer composite material reinforced by fibers, and has, at least, close to one surface structure with fibers oriented predominantly parallel to said surface, in particular derived from swearing or shell made fibers, impregnated with polymers;

- second flat portion bifurcated to form a slot, describing, in particular, the symmetry of the free end of the second part, intended for reception of at least one end section of the first part of the profile.

The invention will be more clearly upon consideration of the attached drawings, in which:

Fig.1 shows a General view in perspective of the insulating system according to the present invention, the "inside", i.e. from the side walls to be isolated;

Fig. 2 shows a schematic top view in section of the insulation system according to the present invention on the damaged wall.

Thermal and acoustic insulation of external walls, not shown in Fig. 1, mainly includes Mat 1 made of fiberglass and mineral finishing plate 2. The optical fiber 1 has �lines the mass of 23.5 kg/m 3. The Mat is available in rolls with a length of 1200 mm (width). After the Mat is unrolled and laid out, it may have a different thickness, in particular 50, 80, 100, 120 and 140 mm.

Mineral finishing plate 2, sold under the registered trademark GlasRoc company Gyproc, has size 2500×1200×12.5 mm; the surface density of 9 kg/m2. Preferably, they have a core that is resistant to water, covered on each side by a reinforcement of glass mats, immersed in the layer of cement modified polymer, which itself each time covered with acrylic coating bonding. Gypsum decoration plates with known such an effect are disclosed in patents US 6 524 679 and WO 2007 004066.

These boards are easy to cut and install, they are resistant to shocks, water, while being permeable to steam. They tolerate humidity.

It contains no paper, no starch conducive to the spread of mold.

They are quite resistant to fire dimensional stability in a wet environment better than cement panels, the bending resistance is relatively high (modulus of rupture greater than 12 MPa). Moreover they do not crumble unlike most cement panels reinforced with fibers.

They are significantly lighter than the cement slabs with fibers of the same size, the surface plane of order�and from 13 to 14 kg/m 2.

Finishing plate 2 is screwed to the metal profile 5 using metallic screws, not represented here.

As noted earlier, the finishing plate 2 is covered with a base coating by adhesion, tissue layer or a lattice, and then finishing plaster.

The finishing joints between slabs reinforced with mortar and reinforcement bars with a width of approximately 10 cm

Note that the insulation system is preferably executed without an air layer, that is, plate 2 are superimposed directly on the exhibition side of the insulating material 1. Likewise, the back side of the material is directly superimposed on the wall that is to be isolated.

This design is preferable because of its simplicity; it gives considerable strength thus made the shell, since it is possible to avoid or to lessen the normal deformation of the finishing plate.

This can be achieved without compromising the integrity of the materials due to the permeability of the finishing plates to water vapours.

However, a vented air gap can be performed by the user at his request or in the case of flattened corrugated metal with a significant layer of plaster instead of gypsum or cement boards. And really, plaster with �nachitelny thickness is poorly permeable.

In the represented embodiment on two drawings, the support and retention of insulation is mainly provided by the interaction of two types of elements: console 3 and metal profiles 5.

The location of the consoles and their number per square meter depends on the load generated by the local wind, is easily calculated by a person skilled in the art. For areas with the strongest winds in Europe are choosing, for example, a console with a height of 1.50 m and a width of 0.60 m. In a preferred embodiment, the space width is reduced to 0.40 m in order to exclude the use of dowels-nails and win, so the installation time: light mineral fiber directly held uprights are quite tight on all sides. For better distribution of workload console are arranged in a checkerboard pattern, alternating with the position of attachment to the wall on each side of the profile along its length.

Console 3 are each 1,20 m 0,60 length and width.

Console 3 have a shear strength of 700 N and tensile strength 3000 N.

Each console 3 contains:

- first substantially flat portion 31 designed for installation with a support on the wall, subject isolation, mostly vertical, and

- the second substantially flat portion 32 perpendicular to the first 31 located vertical�O.

It has L-shaped with the same profile angle as the amount of material in this area forms a thickness in the direction of the bisector of an angle, greater than the thickness of the adjacent flat parts.

The console 3 is fixed to the wall via one or more screws or one pin or equivalent element (there is only one), they can be associated with the dowels inserted into a wall subject isolation.

The second flat portion 32 of the 3 forked with the formation of the slits 34, intended for reception of the base 51 of the vertical T-shaped profile 5. The shape of the slot 34 is consistent with the shape of the base 51 so that

- promotion into this last would be adjustable,

- to move inland was carried out if necessary with some resistance, and the slot 34 can be performed with the possibility of placement with tightness in her part 51 of the base.

When moving deeper adjusted, as necessary, the fastening of the base 51 of the T-shaped profile 5 to the console 3 is carried out using at least one screw 7, and preferably two screws to prevent movement during the rotation.

The console 3 is made of isophthalic polymer reinforced with glass fibers and passed through the pultrusion process with a Mat of long (several centimeters) St�Lovelace, integrated near its surface (from one edge of the slot to the edge of the other slot) on a single thickness of approximately 1-2 mm and short fibers in the mass of the polymer. The thickness of the various flat parts 31 and 32 of the 3 enclosed between 5 and 15 mm, preferably about 10 mm. Usually the slot is formed with a width of about 2 mm with a gap of 0.2-0.5 mm, and the gap is equal to zero at the level of the free edge of the console.

Basically it is a difficult material flammable (conforms to class A2 or European standards). This material has a thermal conductivity of 0.3 V/(m·K), which makes the other part of the console breaker thermal bridge.

T-shaped metal profile 5.

The head portion 52 of the T-shaped profile forms a flat part of the support finishing plates 2.

Finishing plate can be fixed to the profiles coming in contact with an insulating surface without formation of an air layer.

The optical fiber 1 is held returnable wings 53 profile 5.

Metal profile 5 may also have an L-shape, while retaining most of the properties of the T-shaped profile, as described earlier. L-shaped profile is convenient for the separation of holes: doors, doorways, Windows.

In the case of a severely damaged wall (Fig.2) installation of traditional hard insulating element (polystyrene, �acidic rock wool) requires the application of plaster to outline around the front to ensure an acceptable flatness.

This long and costly process can be avoided in this case:

console 3 is attached to the outermost point of the facade, and the metal T-shaped profile 5A deepens the maximum in the console 3A,

- other console 3b are mounted on the wall 0, and the profiles are more or less 5b deepen in the console so that all profiles 5A, 5b would be perfect flatness,

- then finishing plate screwed to the profiles and covered with plaster.

To make up for the defects in several cm below the console 3 are fixed gauge tiles (not presented here). Preferably block tile is brick or concrete block attached to the wall 0 bolts or mortar.

With reference to Fig.1 and 2 in the framework of the present invention is not excluded and is not required that mineral fiber 1 0 is attached to the wall in any way, such as dowel-nail or equivalent.

This system mounts to the wall is reliable without the need for gluing insulating elements, but it avoid the use of components that block the passage of moisture.

The use of consoles, forming a thermal bridge breaker, ensures that the impact of the frame on the U value (heat transfer coefficient U=1/RTwhere RT- the total heat from�rotisserie wall) leads to thermal losses of the wall less than 3%, mostly less than 1%.

The described insulation system is easy, installation is simple and fast, and her behavior is satisfactory under conditions of accelerated aging, as disclosed in ETAG 004: neither external nor structural changes were observed after the passage of heat cycles/rain and freezing/thawing. After these loads mechanical stability was preserved. Its resistance to punctures and impacts is also excellent.
