Definitions

  • the present invention relates to facades light for buildings, as well as manufacturing processes such facades.
  • the object of the present invention is to overcome the disadvantages mentioned above.
  • the invention also relates to a facade of building spanning several floors, this facade of building with facade elements as defined above at each level, the insulating layer thermal and the rain barrier extending so continues from one floor to another: this continuity between floors provides sealing and thermal insulation facade.
  • the projection of the constituent material the thermal insulation layer takes less than two hours after the projection of the material constituting the vapor barrier film.
  • Figures 1 and 2 schematically represent a light facade 1 intended to close a building 2 to insulate the interior 3 of this building vis-à-vis the exterior 4.
  • Building 2 shown in Figure 1 has several floors separated from each other by floors 5, but the invention is also applicable to single-story buildings.
  • the light facade 1 has an exterior facing 6 which generally has no sealing function or thermal or acoustic insulation function. This facing exterior is usually attached to a metal frame outer 7 itself fixed on the edges of the different floors 5.
  • the internal framework consists of metal profiles with U-section which extend vertically between the lower and upper floors 5 of each floor and which are attached to these two floors.
  • U-profiles can be arranged with two wings of their U substantially parallel to the facade 1, but other arrangements can be envisaged, and profiles with different shapes could also be used.
  • the internal framework 9 could possibly be made of a material other than metal, for example wood.
  • the internal framework 9 could possibly be removed if the inner wall 8 had sufficient mechanical strength and if this wall could be securely attached to the floors lower and upper 5.
  • the inner wall 8 is constituted by plates of plaster juxtaposed to each other which extend over the whole height of a storey and which are fixed to the frame interior 9 by screwing or other, on the interior side 3 of the building.
  • the external face 8a of the plates plaster 8 which is directed towards the outside of the building, is consisting of aluminum foil or another waterproof material, which protects said weather drywall between the time they are applied and when the vapor barrier film 10 is applied.
  • the inner wall 8 could be made of a rigid material other than plaster, by for example in wood, plastic or metal.
  • the wall 8, instead of being flat, could if necessary have protruding ribs or undulations towards the outside of the building, to replace the framework 9.
  • the vapor barrier film 10 is a film continuous and waterproof consisting of a waterproof material which is applied to the entire outer face 8a of the interior wall and on the visible parts of the framework 9, and which adheres to this external face 8a and to the framework 9.
  • Application of the material constituting the vapor barrier film 10 is carried out by spraying this material under pressure in a fluid and sticky form, so that said material adheres to the outer face 8a of the inner wall 8 and the internal framework 9.
  • 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 latex-based.
  • this material can 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 combined with surfactants, and about 20% by weight of an aqueous dispersion of a low copolymer acrylonitrile content, this aqueous dispersion comprising lauryl sulfate which represents approximately 1% by weight total 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 lending itself easily sprayed under pressure, and it keeps over time very good elasticity characteristics and water and air tightness.
  • the brand material "BRL” plays a role corrosion inhibitor, in particular thanks to the various agents surfactants it contains, which is particularly interesting for protecting the interior metal 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 remains sticky for about 2 hours.
  • thermoly insulating material Before the drying of the film 10, we project onto this film 10 a thermally insulating material to form the layer 11 of thermal insulation which continuously covers the entire vapor barrier film 10 over the entire height between the lower and upper floors 5 of the stage considered and which adheres to the vapor barrier film 10 of the made of the sticky state of said film 10 at the time of projection.
  • the hanging of the flocking constituting the layer 11 on the film 10 is further facilitated by the frame 9, which protrudes inside layer 11 and thus blocks mechanically this layer 11.
  • layer 11 of insulating material is preferably continuous from floor to floor the other, so as to avoid any creation of a thermal bridge between the interior and exterior of the building.
  • the insulating material used consists of fibers mineral coated with binder which are projected in a flow compressed air and which are wet when they are projection to adhere to each other.
  • This "flame protector” material is composed of wool mineral coated with Portland cement, plaster, clay bentonite, organic binders and dustproof oil.
  • the thermal insulation which can be obtained thanks to layer 11 can be 30% higher than the insulation thermal obtained by the techniques of the prior art, 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 presents, in addition to its thermal insulation qualities, excellent sound insulation characteristics and great thermal inertia which provides good protection against the fire.
  • a layer 11 12 cm thick presents thermal inertia substantially equal to that of a veil in reinforced concrete with a thickness of 16 cm associated with a layer 9 cm thick glass wool, for a density of layer 11 about 10 times less important than concrete.
  • the thermal insulation layer 11 therefore allows to obtain high thermal insulation characteristics and acoustic and fire protection without both have a high weight, which is a characteristic important in any building and in particular in anti-seismic buildings.
  • the outer surface 11a of the insulating layer thermal 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 projected onto the surface 11a, under pressure and in a form liquid, mixed with solvents.
  • the product projected in the form liquid to form the rain barrier layer 12 may be that marketed under the brand "BRH” by the Company RUAUD INDUSTRIES, Z.I. de la Croix Saint-Nicolas, 18 rue Gustave Eiffel, 94510 LA QUEUE-EN-BRIE - FRANCE.
  • This product "BRH” consists of 84% solvents and 16% resin methacrylic, in mass percentages.
  • the microporous resin penetrates a thickness at least 1 cm, and preferably 2 to 3 cm, inside of the thermal insulation layer 11, filling the interstitial voids of this layer of thermal insulation.
  • the rain barrier layer 12 is waterproof with water and thus prevents any infiltration or condensation of water in the thermal insulating layer 11, while remaining breathable.
  • the resin has a anti-defibrating effect, which means that it prevents mineral fibers constituting the thermal insulating layer 11 do not separate from each other thereby reducing the mechanical strength and insulation efficiency of the layer 11.
  • the resin constituting the rain barrier layer 12 generally has fungicidal properties which have a sanitizing action on the fibers constituting the layer thermal insulation 11.
  • prefabricated facade elements comprising layers 8, 10, 11 and 12 and possibly the internal framework 9, then to put together in one piece each of these elements of prefabricated facade in a building.
