Definitions

  • the invention relates to a device for thermally insulating a building partition from the outside, in particular applicable to walls and to roofs, and more particularly such a device making it possible in addition to protect the partition and the insulation against deterioration by climatic assaults such as the sun, wind, snow, rain, etc.
  • the invention also relates to a method for producing and implementing such a thermal insulation device.
  • the first consists in providing—on the inner surface of the walls or the roof of the building—the placement of insulation materials such as glass wool, with a more or less significant thickness with regard to the desired thermal insulation coefficient. It is advisable, however, to leave an air gap between the inner surface of the wall or the roof and the insulation layer, and to cover this insulation layer, on its surface oriented toward the interior of the room to be insulated, by a covering such as plaster plates to maintain the insulation and to ensure correct finishing of the partition. In this case, the thickness of the insulation device impinges upon the living space of the rooms to be insulated.
  • the second technique consists in insulating the partitions of the building from the outside, i.e., to apply and attach a layer of insulation material to the outside of the walls and roofs.
  • the insulation is subjected to climatic assaults that can make it deteriorate quickly.
  • This invention therefore has as its object to propose a device for insulating the partitions of a building from the outside that has an improved resistance to climatic assaults.
  • the invention also has as its object to provide such a thermal insulation device that is suitable for insulating walls or roofs without major modification of the device.
  • the invention also has as its object to provide such a thermal insulation device that can be installed above or instead of an existing roof.
  • the invention has as its object to provide such a thermal insulation device that has high thermal inertia.
  • the invention also has as its object to provide such a thermal insulation device that has an improved ecological impact.
  • the invention relates to a device for thermally insulating a building partition from the outside comprising:
  • the insulation device uses a rigid and impermeable insulation layer formed by, for example, sheets of polystyrene or expanded polyurethane, with a thickness calculated based on the desired thermal resistance, which in turn is dependent upon the location of the structure.
  • This insulation layer can be produced in one or more thicknesses made integral by bonding, for example, when the partition to be covered comprises rough spots where the first insulating thickness makes it possible to level out the surface and the second to produce a continuous cover.
  • the insulation layer is attached by its contact surface to the partition to be insulated, directly or after a vapor-barrier screen is inserted depending on the nature of the partition to be insulated, if necessary attached to battens that are nailed onto, bonded to, or screwed into this partition.
  • a rigid and perforated cladding plate for example one or more plates of sheet metal that is perforated at a distance from the outer surface of the insulation layer, makes it possible to protect the former from the main climatic assaults.
  • a perforated sheet-metal plate makes it possible for the air that surrounds both sides of the plate and preserves a surface temperature that is much lower than that of a solid plate to circulate when it is exposed to full sunlight.
  • the insulation layer is shaded and removed from the influence of direct exposure to solar rays. For example, a perforation level on the order of 20% allows adequate air circulation while keeping 80% of the surface of the insulation in the shade.
  • a cladding plate comprising perforations of 5 mm and placed at 150 mm from the outer surface of the insulation layer makes it possible to limit to 7 minutes the continuous exposure of the insulation for a horizontal partition at the equator.
  • a rigid and perforated cladding plate makes it possible to limit the degradation of the insulation layer under the effect of exposure to sunlight.
  • it makes it possible, thanks to its rigidity, to protect the insulation layer against the energy of the wind and the direct impact of rain or hail.
  • the perforated cladding plate constitutes a protective layer in the case of snow by making it possible to support the weight of the snow layer, to minimize the risks of the layer sliding while making it possible to evacuate melt waters.
  • the thermal insulation device in addition comprises a granular insulation layer, in divided form, between the insulation layer and the cladding plate.
  • the granular insulation is a porous granular insulation, constituted by, for example, expanded clay balls or pumice stone gravel.
  • the thermal insulation device makes it possible to adjust liquid flow rates by promoting water retention in the granular insulation layer without having an unfavorable impact on the performance of the rigid and impermeable insulation layer that supports it.
  • the delayed release of the amount of water retained in the granular insulation layer contributes to maintaining a moderate temperature on the outside partitions of a thus equipped structure and, particularly in tropical climates having rapid alternation of precipitation and strong sunlight, makes possible a natural climate control of the structure's environment.
  • the granular insulation layer also contributes, depending on its nature, to fixing on certain pollutants contained in the rainwater and makes it possible to improve the quality of wastewater. Even by use in dry climates, the granular insulation layer makes it possible to increase the overall thermal inertia of the insulation device according to the invention and therefore to improve its performance.
  • the granular insulation in divided form that is used comprises expanded clay balls that can have, depending on their finishing, either good porosity or an impermeable surface.
  • the density of the expanded clay balls is relatively low, on the order of 500 kg/m 3 , which makes it possible to use them on roofing without excessively weighing down the cover and makes it unnecessary, under certain conditions, to consolidate or modify the existing carrying structure.
  • volcanic materials such as pumice stone or pozzolan can be used, in the form of grains or gravel.
  • the granular insulation is contained in at least one synthetic textile bag.
  • the synthetic textile has the advantage of being non-porous and therefore able to stand the test of time and face the elements (rain, snow, etc.) and therefore to prevent the granular insulation in divided form from expanding.
  • the synthetic textile is a non-woven synthetic textile, in particular a needle-bonded geotextile.
  • the insulation device according to the invention calls for using non-porous synthetic textile bags, woven or non-woven, for example made of polypropylene needle-bonded geotextile felt, which offer the advantage of being naturally porous and of being able to be easily made in numerous dimensions by folding and heat-sealing the edges between them.
  • any other textile that is woven or not can be used, provided that it can be closed by sewing, bonding, heat-sealing, etc.
  • an impermeable textile can be used by producing—on its surface—perforations making it possible for water to enter toward the granular insulation.
  • each bag has an essentially cylindrical shape, with an axis defining an installation orientation and a diameter that is smaller than or equal to the distance between the outer surface of the insulation layer and the cladding plate.
  • the simplest shape for the bags containing the granular insulation layer is in the shape of essentially cylindrical flanges that are obtained by folding a textile rectangle along its length and sealing its long edges to one another. One of the short edges is then closed by heat-sealing, and the bag is then filled by granular insulation.
  • the bag is filled to only 80% to allow its flattening against the rigid insulation layer during the installation.
  • each bag has an essentially parallelepiped shape and comprises partitions, so-called separation partitions that are rectangular, parallel, and uniformly-spaced and whose long edges define an installation orientation and are attached to the main surfaces of each bag so as to keep between said main surfaces a distance that is less than or equal to the distance between the outer surface of the insulation layer and the cladding plate.
  • the bags come in the form of rectangular cushions whose thickness is kept essentially constant by intermediate partitions.
  • the bags are made from two rectangles between which the separation partitions that form parallel cavities are sealed and whose edges parallel to the partitions are sealed between them and one of the perpendicular edges.
  • the bags are then filled by the edge that is perpendicular to the partitions and that is not yet sealed in such a way as to distribute essentially equally the granular insulation in the cavities, and then the bag is closed by heat-sealing of the last edge.
  • At least a part of the textile partitions of each bag is perforated. Even if the geotextile felt used for producing the bags is naturally porous, it is preferable to make additional perforations so as to promote the intake of rainwater into the granular insulation layer. Preferably, it is the surface of the bag opposite the cladding plate that is perforated in the case of a parallelepiped bag.
  • each bag is attached to the rigid insulation layer in such a way that its installation orientation is orthogonal to a greater pitch line of the insulation layer. So as to prevent excessive packing of the granules of the insulation under the action of gravity, the bags are attached to the rigid insulation layer in such a way that their largest dimension is orthogonal to the pitch line of the partition.
  • the axis of the cylindrical bags or the direction of the partitions for separation of the parallelepiped bags is in general horizontal to keep the granular insulation from being packed down at one end of the bag.
  • the rigid insulation layer comprises on its outer surface an anti-sink coating to which the spacers are attached. So as to prevent a perforation of the rigid insulation layer, either by the weight transmitted by the spacers or by the actions and movements of the workers during the installation of the insulation device according to the invention, it is preferable to provide an anti-sink coating to the surface of the insulation of the rigid insulation layer.
  • an anti-sink coating is often integrated upon the manufacturing of the insulation that is delivered bonded to a surface with a rigid plate ensuring the rigidity and the anti-sink protection of the insulation.
  • the anti-sink coating is not part of the rigid insulation layer from the outset, it can be added in the form of a sheet-metal plate, preferably solid, or laminated bonded to the insulation to form the rigid insulation layer.
  • the spacers are attached to the rigid insulation layer with a predetermined span along parallel lines.
  • the spacers are attached along lines that are orthogonal to a greater pitch line of the insulation layer.
  • the spacers are preferably made in the form of rectangular parallelepipeds made of folded perforated sheet metal, comprising, if necessary, a main surface that is partly open.
  • the spacers are placed in a uniformly-spaced manner, in parallel lines, orthogonal to the greater pitch line of the partition to which the rigid insulation layer is attached. In general, for vertical walls or roof sections, the spacers are aligned horizontally.
  • the spacers are offset by a half-step between two adjacent lines. They are attached by their longest lateral surface to the anti-sink coating of the rigid insulation layer by any suitable means, for example by bonding, screwing, riveting, or any combination of these means.
  • the spacers of the same line are connected to one another by small U-shaped beams that cover said spacers.
  • the cladding plate is attached to the small U-shaped beams.
  • the spacers are made integral with one another by small U-shaped beams, preferably made of folded perforated sheet metal and comprising two wings that are separated by a core with a suitable inside width to allow the two wings of the U to cover each spacer.
  • the minimum length of the small beams is adapted so that each small beam can cover at least partially a spacer at each end of the small beam.
  • the mounting of the small beams is preferably carried out without overlapping in such a way that the outside surface of the core of each small beam is in a plane that is common for each partition. It is thus possible to place perforated cladding plates on the small beams and to attach them in a simple manner, for example by means of blind rivets passing through the perforations of the cladding plate and of the small beam.
  • the cladding plate is adapted for receiving cover accessories that are adapted to be attached to said cladding plate.
  • the rigid and perforated cladding plates make it possible to attach devices such as photovoltaic solar panels or fluid circulation panels directly onto the roof sections and/or onto the walls and to guide their cables or connecting lines.
  • fluid circulation coils can be simply hooked onto the perforated cladding plates, for example by means of clamps, in such a way as to constitute a heating network for the purpose of accelerating the melting of a layer of snow deposited on the cladding.

  • an impermeable textile can be used by producing—on its surface—perforations making it possible for water to enter toward the granular insulation.
  • Such a bag 10 is illustrated in perspective intersected by a median plane as in FIG. 4 and comprises two main rectangular surfaces 14 a and 14 b placed opposite one another and whose respective edges are heat-sealed to one another for forming a closed bag.
  • the main surface 14 a is in addition perforated in such a way as to make possible a direct intake of rainwater.
  • rectangular separation partitions 11 are placed parallel to one another and sealed to the two main surfaces by a flap 15 formed on their long edge so as to define cavities 16 .
  • the width of the separation partitions 11 is provided to keep the thickness of the layer 8 of granular insulation 9 essentially constant.
  • the filling of the cavities 16 of the bag 10 is carried out by one of the edges that are orthogonal to the separation partitions, and then the edge is closed by heat-sealing edges opposite the main surfaces.
  • the dimensions of the bags 10 are provided to be multiples of the span P for the length so as to place them parallel to the lines of spacers 4 supported on at least two spacers and for corresponding to the spacing between two lines of spacers for the width.
  • the bags 10 are attached to the outer surface of the rigid insulation layer 3 by glue beads 12 , parallel to the lines of spacers.
  • the bags 10 are arranged in such a way that the direction of the separation partitions 11 , which also defines the largest dimension of the cavities 16 , is parallel to the lines of spacers 4 (and therefore perpendicular to the greater pitch line of the partition on which the insulation device is placed) in such a way that the length of the cavities 16 is also orthogonal to this greater pitch line (see FIG. 3 ).
  • the dimensions of a bag 10 adapted to the thermal insulation device whose dimensions were given above are on the order of 600, 1200 or 1800 mm long, 600 mm wide, and the constant thickness maintained by the separation partitions 11 is on the order of 100 mm.
  • the bags 10 can be made of a single cavity formed by a cylindrical casing obtained by folding a geotextile felt sheet on itself and sealing its edges in such a way as to form a cylinder with a length of one, two, or three spans P and a diameter that is approximately equal to the distance existing between the outside surface 32 of the rigid insulation layer 3 and the cladding plate 6 .
  • the cylindrical bag is filled to only 80% of its capacity, making possible its flattening on at least two glue beads 12 to obtain an oblong cross-section whose small diameter corresponds to the desired thickness of the granular insulation layer 8 .
  • the cylindrical bags are arranged in such a way that the axis of the cylinder (which corresponds to the largest dimension of the single cavity) is parallel to the lines of spacers 4 , with multiple bags being used to fill the spacing between two lines of spacers.
  • the bags 10 can be arranged in parallel rows or staggered, each bag resting on two other bags.
  • the thermal inertia of the insulation device and therefore of the building that is insulated with this thermal insulation device is improved.
  • the rainwater reaching the cladding plate 6 passes through it at least in part owing to its perforations and reaches the granular insulation layer 8 in which it is temporarily trapped.
  • the streaming of the rainwater is thus slowed, minimizing the risks of clogging from rain drainage.
  • the evaporation of trapped water creates a phenomenon of local climate control.
