Definitions

  • the present invention relates to roof insulation for buildings.
  • the invention relates to insulation panels for roofing.
  • a roof is generally made with sloped rafters spaced about 600mm apart, and connecting a low side beam (called a sand pit fault) to a horizontal top beam (called a blackout). Then horizontal slats are fixed on said rafters with a spacing allowing the mounting of tiles.
  • the space left between the rafters must be filled with insulation, which allows the heat to pass easily.
  • the quality of such insulation will depend on the proper filling of the space, and the maintenance in time of this good filling. If spaces are left empty, where the air can circulate, and so hot air and cold air can mix, this constitutes "thermal bridges", through which the heat will pass preferentially, and the insulation will be globally deteriorated and ineffective. If one succeeds a good insulation between the rafters, it is the chevron itself which ends up allowing more heat to pass than the added insulation, and constitutes itself a thermal bridge. We can then improve the overall insulation by also removing this thermal bridge.
  • the internal insulations for roofing are made according to the state of the art for example by mineral wool, glass wool or rock wool, enclosed between two rafters.
  • mineral wools are irritating to the skin, which makes the pose unpleasant.
  • they are classified as carcinogenic in category 3 by CSTB and radioactive.
  • Another solution of the state of the art consists for example of polyurethane panels. These panels are rigid, and therefore not likely to sag in time. But once installed, this type of panel has openings at the joints between two adjacent panels and between a panel and the adjacent chevron, which constitute enormous thermal bridges. To seal these openings is used foam, for example polyurethane also. This leads to extra work, which is often not done correctly, so that there are still some openings at some joints. These constitute thermal bridges through which heat passes, and which seriously deteriorate the overall insulation performance.
  • Another solution sometimes applied is to make two layers of polyurethane panels, the joints of the second layer being offset from those of the first layer. This solution is labor intensive, and does not improve the problem, however, without solving it completely, only for the joints between two adjacent panels, and does nothing to remove the openings between panels and adjacent chevrons. In addition it increases the difficulty of implementation.
  • the gas that gives the polyurethane foam its insulating power is not trapped in closed cells and escapes over time thus making the material porous and ineffective thermally.
  • polyurethane is highly flammable and releases toxic gases in case of fire. Because of this, it is forbidden to use for public buildings.
  • the invention aims to meet these needs, and to solve many of the problems posed by the state of the art.
  • a panel for interior insulation of a roof to be inserted between rafters of said roof.
  • This panel is remarkable in that it is made of a rigid insulating material, elastic and breakable and that it has in plan a parallelogram shape with a right angle.
  • Rigidity allows stability of panel geometry over time, thus maintaining insulation performance for many years.
  • air the only natural insulator on earth, is trapped in closed cells, is a guarantee of thermal efficiency over time, the product being classified as rot-proof (according to CE standards).
  • the oblique positioning as well as the spacing of 2 mm of the breakable parts arranged on each side of the panel can compress the panels on the one hand against the rafters of the roof, on the other hand against the adjacent panels, so that the panel by seeking to return to its original shape, which is the characteristic trend of an elastic material, fills the interstices due to imperfections in geometry, in particular rafters of the roof.
  • the parallelogram shape gives greater flexibility to the panel, thus making it possible to catch larger imperfections than could a rectangle (parallelogram at right angles).
  • the two edges of said parallelogram intended to come into contact with adjacent panels are V-shaped.
  • the two panels will remain perfectly flush against each other without any risk of opening of the insulating structure and level thermal bridges such as those encountered with rectangular panels polyurethane.
  • said V-shaped is asymmetrical, the small branch of the V preferably being oriented towards the outer face of said roof. This arrangement allows an easier installation of the panels and a seal tight to temperature and humidity.
  • the notches are arranged close to the edge of the two small sides of said parallelogram, with a depth greater than half the thickness of said panel, preferably of the order of 80%. the thickness of said panel. It is thus possible, by breaking the edge at the location of one of the notches (scored part) modify the width of said panel to adapt to the actual spacing observed between two rafters of said roof.
  • the material constituting the panel is expanded polystyrene.
  • This material is classified M1 fire by the CSTB, and has no toxicity or gene for the editor.
  • pads are arranged on the outer face of said panel. This gives perfect ventilation under the battens.
  • At least one groove is disposed on one of the long sides of the outer face of said panel, said groove forms a channel.
  • the thickness of said panel is greater than that of the rafters of said roof, so that by covering said panels by a non-elastic plaster board type panel, a board air is trapped between the chevron and said non-elastic panel. This provision eliminates the thermal bridge constituted by said rafters.
  • the invention relates to an interior roof insulation in which panels according to the invention are placed between the rafters of said roof for example by the interior of the building.
  • the roof insulation according to the invention is made with panels which have a geometry or a generally rectangular plate shape namely two relatively flat faces and four end edges, two of which large and two small.
  • these panels intended to be placed on the rafters or in any case the frame of the roof supporting tiles are placed on surfaces whose flatness is not certain. As a result, the panels can move relative to the rafters and / or between them.
  • This tongue / groove geometry is the geometry known since prehistory in the form of a dovetail and tenon / mortise fasteners.
  • the assembled panels form a whole and are maintained but can separate and develop hollows between the panels.
  • the invention also relates to the use of panels according to the invention for a quick and direct installation between the rafters of a roof.
  • the present invention also relates to the use of insulating panels in accordance with those described for a quick and direct installation on rafters or voliging to ensure total waterproofness to rainwater and condensation, to powder snow and to dust.
  • the song A is represented in front view of the figure 3 .
  • the reference signs representing the same elements appearing in several figures are kept identically.
  • This view shows the notches 6 made near the edges C and D.
  • five notches 6 are arranged, 5 mm wide, and spaced 2 mm, and a depth of 80% compared to the thickness of the panel. They allow at the time of assembly of the panel to adjust the width of the panel to the actual space between two rafters 9, breaking by hand at one of the notches 6. This gives a new song C or D perfectly planar over the entire thickness in contact with the adjacent chevron 9.
  • the thickness of the panel 1 is greater than that of the chevron 9 so that the "broken" part is not in contact with the chevron 9, thus ensuring a perfectly flat edge on all the part in contact with said chevron 9.
  • the song B is represented in front view of the figure 4 .
  • This song is similar to the song A, with in addition 5 channels disposed on the outer face, to evacuate the condensation water.
  • the songs C and D are represented in front view of figures 5 and 6 by the example of the song C, the song D being symmetrical to the song C.
  • the particular profile of the songs A and B in the form of asymmetrical V-shape.
  • the small branch 7 of the V is located towards the outer face of the panel, and in the exemplary embodiment shown has a width of 20 mm over a height of 30 mm.
  • the large branch 8 of the V located towards the inner face of the panel has in the embodiment shown a width of 130 mm, a height also 30 mm.
  • the total thickness of the panel is in this case 150 mm.
  • the figure 7 presents a mounting of several panels 1,1a, 1b.
  • the first panel 1, mounted at the bottom of the roof, must be cut along a line perpendicular to its short sides. It thus takes a triangular or trapezoidal shape, and has a type B edge to receive the next panel 1a. Said panel 1a following is engaged, its edge A leaning against said edge-type B of the panel 1, after being adjusted in length through the notches 6, as indicated above.
  • the elasticity due to the material as well as the remaining notches 6 makes it possible to compress the panels 1, 1a, 1b by putting them in place.
  • the panels 1, 1a, 1b are held by compression between the rafters 9, their elasticity to fill the imperfections of the rafters 9 and thus remove the thermal bridges in the vicinity of the rafters 9.
  • a pressure is exerted also by the panel 1a, 1b on the adjacent panel 1, 1a, creating again a perfectly closed joint between the two panels, the V-shaped to prevent any risk of sliding between two adjacent panels 1.
  • This embodiment may be particularly suitable in the case of rafters 9 whose geometry is of particularly poor quality.
  • Plots 4 typically of a height of 4 mm and a diameter of 20 mm are arranged on the outer face 2 of the panel 1, thus creating an airy space under the lathing 10. This prevents moisture from settling and does not deteriorate slats 10 or tiles 11.
  • the lengths P of the small and G of the long sides of the parallelograms as well as its angle ⁇ may vary, the panels 1 being able to have, for example, a substantially diamond-like shape, or even with a length G of the long side A, B smaller than the length P small sides C, D, without departing from the scope of the invention.
  • the V shape can be replaced by a tilde shape, or any other form capable of ensuring that two adjacent panels compressed towards each other remain flush with respect to each other.
  • Border B is represented front view on the Fig 11 .
  • This border has two tabs 18 and 19 complementary grooves 16 and 17 intended to match the grooves 16 and 17 of an adjacent panel.
  • the lower tongue which protrudes more than the lower tongue has a groove 22 and the tongue 18 a groove 23 as it appears on the Fig. 4 which represents the border C seen from the front.
  • the border C has a large lower tab 20 and a small upper tab 21. These tabs 20 and 21 run over most of the length 1 of the border C.
  • the border D over most of its length 1, has a lower groove 22 and an upper groove 23.
  • the edge D of a first panel 1a cooperates with the edge C of a second panel 1b; thus the tongue 20 matches the groove 22 and the tongue 21 matches the groove 123.
  • the faces C and D are also in the upper part of length 1 offset with respect to the length 1 of the lower parts.
  • the assembly of the panels 1a, 1b, 1e to obtain the roof insulation is by sliding the grooves 15, 16, 22 and 23 in the tabs 18, 19, 20 and 21.
  • the shape of the tabs 18, 19, 20 and 121 makes it possible to give them a clip effect during assembly of the panels. Thus, it is obtained a good flatness and a good joint between the panels.
  • the double groove and tongue assembly system in the upper and lower part of the edges A and B, C and D with channeling in the tongues makes it possible to obtain the tightness and insulation of all the panels 1a, 1b and 1e assembled.
  • the pipes 24, 25, 26 and 27 incorporated or formed in the tongues 18, 19, 20 and 21 drain the rainwater and condensation to the sewer and prevent the installation of a roofing film as require the known groove-tongue junction systems.
  • Some tabs 19 and 120 have thicknesses at their ends which prohibit any gap between the panels 1a, 1b and 1c. producing a clipping effect.
