Definitions

  • the present invention relates to the building sector, in particular waterproofing and insulation of roofs, and has for object a vapor barrier membrane, as well as an insulating and sealing complex or sealing comprising in particular such a membrane.
  • the layers of insulating and waterproofing coatings are fixed on the roofs by through mechanical fasteners passing through the insulating layer and, the if necessary, part of the vapor barrier membrane placed under the insulation and on the steel support.
  • the first consists in making the insulating layer in one material insensitive to humidity, such as for example cellular glass, but it results in a significant additional material cost.
  • the second solution consists in sealing, with respect to rising steam, the supporting elements of the roof, such as for example ribbed steel sheets, at their areas of overlap and at the orifices of passage of the fixing means (screws or the like).
  • the implementation of this solution is difficult to manage on site and tedious in its application.
  • the third solution proposed is to set up between the roof support components and the insulating layer a layer vapor barrier, intended to prevent the formation of condensation water in the insulation by forming a barrier between the latter and the interior of the building likely to present an atmosphere charged with water vapor.
  • Vapor barrier layers are generally of two types, know, a deck of thin sheets coated with a bituminous membrane or a bituminous membrane placed directly on the steel sheets ribbed.
  • the first type of vapor barrier involves an additional cost important and overweight for the considered work and requires work additional sealing to achieve a vapor barrier layer perfectly waterproof to water vapor.
  • the second type of vapor barrier has resistance limited mechanics, especially at the level of the ribs of the sheets.
  • bituminous membrane requires, in both cases mentioned above, the integration, in its thickness, of a continuous layer impervious to steam, particularly aluminum foil, which can withstand bituminous coating temperatures.
  • nonwoven webs can constitute cavities. or fibrous lumps that can retain moisture and the webs themselves can permeate by capillarity and thus allow penetration of water in the thickness of the vapor barrier.
  • bitumen must be force-impregnated in order for it to be present over the entire thickness of the tablecloth.
  • the present invention aims in particular to overcome the aforementioned drawbacks.
  • a vapor barrier membrane based bitumen characterized in that it comprises a composite reinforcement consisting of a thin sheet of aluminum and a grid in one material with high mechanical resistance, joined together by laminating, said composite reinforcement being coated on its two faces with layers of bitumen-based materials, possibly of compositions different.
  • said vapor barrier membrane 1 comprises a composite reinforcement constituted by a thin sheet continuous aluminum 2 or an aluminum-based alloy and by a grid 3 made of a material with high mechanical resistance, assembled together by laminating, said composite reinforcement 2, 3 being coated on its two faces of layers of bitumen-based materials 4 and 5 possibly of different compositions (one layer per side).
  • the grid 3 / sheet 2 connection by suitable bonding prevents any drilling or perforation of said aluminum sheet and allows keep a continuous layer of aluminum and therefore to said membrane composite 1 to be used as a vapor barrier.
  • the composite reinforcement is composed of a grid of wires or filaments high-strength synthetic or mineral continuous materials, especially of glass wire grid 3, laminated on a thin aluminum sheet 2 having, if necessary, a hammered surface favoring the adhesion of layers of bituminous materials and bending without generating lines of crease or weakened lines.
  • the son or filaments of the grid 3 may advantageously be treated or trained to be completely powerless by capillarity.
  • the advantageous implementation of a grid 3 of glass strands gives membrane 1 a high mechanical resistance and an absence elongation under stress, at least in the directions of orientation of said sons.
  • the upper layer of the bituminous coating 4 is treated to present a surface 4 'to privileged attachment especially for fixing an insulating layer 6 traditional thermal and / or acoustic.
  • the upper layer of the coating bituminous 4 has a surface 4 'sanded or having been subjected to a similar treatment, allowing hot and / or cold bonding of the insulation layer 6.
  • the covering layer bituminous lower 5 consists of a bituminous mixture with properties sticky, preferably self-adhesive when cold on steel or concrete.
  • the aluminum sheet 2 may have a thickness between 10 ⁇ m and 100 ⁇ m, preferably between 20 ⁇ m and 70 ⁇ m, and the glass grid 3 consist of glass strands of title between 40 tex and 100 tex, preferably between 60 tex and 80 tex and arranged in a network with two components substantially orthogonal to each other, the 3 'wires, 3 "of each component being spaced by an interval between 1.5 mm and 10 mm, preferably between 3 mm and 4 mm.
  • the sheet / grid laminating can be done using an adhesive suitable for the materials present and resistant to temperatures bituminous coating, for example an acrylic emulsion type adhesive and / or butadiene.
  • the subject of the present invention is also, as shown in particular Figure 2 of the accompanying drawings, an insulating complex or system and waterproofing for roofs, in particular of buildings subjected to high or very high humidity, characterized in that it is mainly made up, on the one hand, by a vapor barrier membrane 1 as described above resting on the support or the roof support elements, on the other hand, by a layer of insulating material 6 added by cold or hot gluing on said vapor barrier membrane 1 and, finally, by one or more layer (s) of outer sealing coating 7 added to said layer insulating 6, by cold gluing, hot gluing or thermofusion.
  • the vapor barrier membrane 1 has a cold self-adhesive underside on steel and / or concrete and is attached by bonding to the support elements 8 components of the roof, such as ribbed steel sheets, allowing remove any mechanical fixation likely to pass through the membrane vapor barrier 1, the insulating layer 6 and / or the steel tanks.
