Definitions
- the present invention relates to light facades for buildings, as well as to the methods of manufacturing such facades.
- the present invention aims to overcome the aforementioned drawbacks.
- the invention also relates to a building facade extending over several floors, this building facade comprising facade elements as defined above at each floor, the thermal insulating layer and the barrier layer. rain extending continuously from one floor to another: this continuity between floors allows a perfect seal and thermal insulation of the facade.
- the projection of the material constituting the thermal insulating layer takes place less than two hours after the projection of the material constituting the vapor barrier film.
- FIGS. 1 and 2 schematically represent a light facade 1 intended to close a building 2 to isolate the interior 3 of this building from the exterior 4.
- the building 2 shown in Figure 1 has several floors separated from each other by floors 5, but the invention is also applicable to buildings with a single floor.
- the light facade 1 has an exterior facing 6 which generally has no sealing function or thermal or acoustic insulation function.
- This external facing is generally fixed to an external metal frame 7 which is itself fixed to the edges of the various floors 5.
- the internal framework is constituted by metal sections with U-shaped section which extend vertically between the lower and upper floors 5 of each floor and which are fixed to these two floors.
- the U-shaped profiles can be arranged with the two wings of their U substantially parallel to the facade 1, but other arrangements can be envisaged, and profiles having different shapes could also be used.
- the internal framework 9 could possibly be made of a material other than a metal, for example wood.
- the internal framework 9 could possibly be removed if the internal wall 8 had sufficient mechanical strength and if this wall could be securely fixed to the lower and upper floors 5.
- the inner wall 8 is constituted by plasterboards juxtaposed with one another which extend over the entire height of a storey and which are fixed to the inner framework 9 by screwing or other, on the interior side 3 of the building.
- the external face 8a of the plasterboard 8 which is directed towards the outside of the building, is constituted by a sheet of aluminum or of another waterproof material, which protects said plasterboard bad weather between the time they are applied and the time when the vapor barrier film 10 is applied.
- the inner wall 8 could be made of a rigid material other than plaster, for example wood, plastic or metal.
- the vapor barrier film 10 is a continuous and waterproof film constituted by a waterproof material which is applied to the entire external face 8a of the interior wall and to the visible parts of the framework 9, and which adheres to this external face 8a and the frame 9.
- the material constituting the vapor barrier film 10 is applied by spraying this material under pressure in a fluid and tacky form, so that said material adheres to the external face 8a of the internal wall 8 and to the internal framework.
- the vapor barrier film thus obtained preferably has a thickness at least equal to 150 ⁇ m and a surface density at least equal to 200 g / m 2 .
- the material constituting the vapor barrier film 10 is preferably based on latex.
- this material may be that marketed under the brand "BRL” by the company RUAUD INDUSTRIES, Z.I. de la Croix Saint-Nicolas, 18 rue Gustave Eiffel, 94510 LA QUEUE-EN-BRIE - FRANCE.
- This material consists of approximately 80% by weight of latex associated with surfactants, and approximately 20% by weight of an aqueous dispersion of a copolymer with a low acrylonitrile content, this aqueous dispersion comprising lauryl sulphate which represents approximately 1% of the total weight of the material, and a water-soluble thickener, in particular polyurethane, which represents 2% of the total weight of the material.
- This "BRL" material has the advantage of being easy to spray under pressure, and it retains over time very good elasticity and water and air tightness characteristics.
- the brand material "BRL” plays a role of corrosion inhibitor, in particular thanks to the various surfactants which it contains, which is particularly advantageous for protecting the internal metallic framework 9 against any corrosion coming from a hypothetical water infiltration or condensation of water vapor inside the layer 11 of insulating material.
- the material constituting the vapor barrier film 10 dries gradually, but it remains tacky for approximately 2 hours.
- a thermally insulating material is projected onto this film 10 to form the layer 11 of thermal insulation which continuously covers the entire vapor barrier film 10 over the entire height between the floors lower and upper 5 of the stage considered and which adheres to the vapor barrier film 10 due to the tacky state of said film 10 at the time of projection.
- the attachment of the flocking constituting the layer 11 on the film 10 is further facilitated by the framework 9, which projects inside the layer 11 and which thus mechanically blocks this layer 11.
- the layer 11 of insulating material is preferably continuous from one floor to another, so as to avoid any creation of a thermal bridge between the interior and outside the building.
- the insulating material used consists of fibers mineral coated with binder which are projected in a stream of compressed air and which are wetted at the time of their projection to adhere to each other.
- This "flame retardant" material is composed of mineral wool coated with Portland cement, plaster, bentonite clay, organic binders and dustproof oil.
- the thermal insulation which can be obtained thanks to the layer 11 can be 30% greater than the thermal insulation obtained by the techniques of the prior art, for equal thickness.
- the layer of insulating material 11 preferably has a thickness between 1 cm and 15 cm, and a density which can be for example between 200 and 250 kg / m 3 , advantageously close to 230 kg / m 3 .
- the layer 11 has, in addition to its thermal insulation qualities, excellent acoustic insulation characteristics and a high thermal inertia which allows good protection against fire.
- a layer 11 12 cm thick has a thermal inertia substantially equal to that of a reinforced concrete veil with a thickness of 16 cm associated with a layer of glass wool 9 cm thick, and this for a density of layer 11 about 10 times less important than concrete.
- the thermal insulating layer 11 therefore makes it possible to obtain high thermal and acoustic insulation and fire protection characteristics, without however presenting a high weight, which is an important characteristic in any building and in particular in anti-seismic buildings.
- the outer surface 11a of the thermal insulating layer 11 is covered by a rain barrier layer 12 which extends continuously over the entire outer surface 11a, and preferably continuously from one floor to another when the building has several floors.
- This rain barrier layer consists of a microporous resin based on methacrylic resin, which is sprayed onto the surface 11a, under pressure and in a liquid form, mixed with solvents.
- the product projected in liquid form to form the rain barrier layer 12 could be that marketed under the brand "BRH” by the company RUAUD INDUSTRIES, ZI de la Croix Saint-Nicolas, 18 rue Gustave Eiffel, 94510 LA QUEUE-EN-BRIE - FRANCE.
- This "BRH” product consists of 84% solvents and 16% methacrylic resin, in mass percentages.
- the microporous resin penetrates over a thickness of at least 1 cm, and preferably over 2 to 3 cm, inside the thermal insulating layer 11, by filling the interstitial voids of this thermal insulating layer.
- the rain barrier layer 12 is waterproof and thus prevents any infiltration or condensation of water in the thermal insulator layer 11, while remaining permeable to air.
- the resin has an anti-defibrating effect, which means that it prevents the mineral fibers constituting the thermal insulating layer 11 do not separate from each other, thereby reducing the mechanical strength and the insulation efficiency of the layer 11.
- the resin constituting the rain barrier layer 12 generally exhibits fungicidal properties which have a sanitizing action on the fibers constituting the thermal insulating layer 11.
- prefabricated facade elements comprising the layers 8, 10, 11 and 12 and possibly the internal framework 9, then to install each of these elements in a single block. prefabricated facade in a building.
