Definitions

  • the present invention relates to roofing systems used for sealing and insulating roofs, in particular but not exclusively in ribbed steel sheets, and it aims at improvements to those of these systems using insulating polystyrene panels. expanded.
  • the insulation and sealing system described in this patent consists in first fixing on the support to be protected common expanded polystyrene sheets by means of a cold glue, then to be applied to these sheets, also cold. , a first sealing layer the first self-adhesive sealing layer applied to the expanded polystyrene sheets.
  • this first sealing layer may not be done immediately during its application, due in particular to unfavorable atmospheric conditions, or for any other reason. It follows that the first sealing layer may not be completely waterproof, in particular at the junctions of the sheets, which affects the quality of protection of the system.
  • the present invention aims to remedy this drawback by proposing a means which guarantees the tightness of the first self-adhesive sealing layer of this system.
  • the present invention consists in using, with a view to constituting the first sealing layer, self-adhesive sealing sheets having at the edge, unilaterally, a heat-weldable space, so that the overlapping edge of each sheet is made up of two parts, one of which, set back from the edge, is self-adhesive when cold and the other, at the edge, is heat-sealable.
  • the present invention thus relates to an insulation and sealing system comprising the successive application, on the support to be protected, of expanded polystyrene plates fixed by means of a cold glue, then a first layer of self-adhesive sealing and finally a second heat-sealed sealing layer on the first, this system having the characteristic of using self-adhesive sealing sheets which also constitute an object of the invention.
  • the sealing sheets according to the invention have the characteristic of having a self-adhesive lower face over their entire surface, with the exception of a heat-sealable strip located at the edge, unilaterally, and constituting part of the selvedge covering said sheets, the other part of this selvedge being self-adhesive.
  • the sealing sheets according to the invention are preferably made of a material based on oxidized bitumen or on bitumen modified by polymers, reinforced by a reinforcement of organic fibers such as woven or non-woven polyester or polyamide fibers.
  • the self-adhesive face of the sealing sheets according to the invention is protected by a protective sheet detachable at the time of use, such as a sheet of silicone paper or a sheet of silicone polypropylene.
  • the braid formed at the edge of the sealing sheets according to the invention preferably has a width of the order of 5 cm, approximately equal to half the width of the covering edge, which is generally 8 to 12 cm wide. It can advantageously be covered with a film of a heat-fusible synthetic material, such as polypropylene or polyethylene, intended to facilitate welding.
  • a heat-fusible synthetic material such as polypropylene or polyethylene
  • the advantage inherent in the present invention resides in the fact that the self-adhesive part of the covering edge provides sufficient sealing of the first sealing layer until the heat sealing of the other part, which guarantees perfect sealing of said layer.
  • the support 1 to be protected is seen covered with a layer of expanded polystyrene 2 to which is applied a first sealing layer formed of sheets 3 and 4 comprising an adhesive underside 5.
  • the selvedge covering sheets 3 and 4 is formed by a part 5 ′ self-adhesive and part 6 hot welded.
  • the first sealing layer 3-4 is covered by a second sealing layer 7 heat welded.
  • sealing sheets As an example of sealing sheets according to the invention, the one having the following characteristics can be given: - composition: mixture of bitumen and styrene-butadiene-styrene (SBS) - frame: complex sheet of non-woven polyester fibers and a glass grid, weighing 180 g / m2. - self-adhesive underside - 5 cm wide heat-sealed border, covered with a polypropylene film of 8 micrometer thickness.
  • SBS bitumen and styrene-butadiene-styrene
  • This sheet has, among other properties: - tensile strength: 1000 newton / 5 c - elongation at break: 30% - resistance to static punching: more than 15 kg - cold flexibility at - 15 ° C: no crack - heat resistance: greater than 100 ° C. - tear resistance: greater than 300 N. - nominal thickness: 3 mm.
  • sealing sheets according to the invention if they find a particularly advantageous application in the insulation and sealing system which has just been described, can also be used with advantage in systems of different sealing using self-adhesive sealing sheets.
