Definitions

  • the invention relates to a sarking membrane for pitched roofs, consisting of a vapor diffusion-open but surface-water-tight film and a reinforcement layer.
  • the present invention has for its object to provide a sarking membrane, which has only a very low water vapor diffusion resistance, but which is still surface waterproof and very flexible and adapts well to the unevenness of the roof or the underlying thermal insulation layer, nevertheless has sufficient tensile strength and, in particular, does not require any ventilation space between the underlay and insulation material.
  • the solution to this problem consists according to the invention of a film and an associated reinforcing layer made of an open-pore soft foam and a reinforcement arranged between the soft foam and the film made of a tear-resistant mesh fabric with a diffusion-equivalent air layer thickness of 0.07-0.12 mm.
  • the film expediently has a thickness of 20-40 ⁇ m, in particular 25-30 ⁇ m, and consists of polyurethane.
  • the film can also be provided with a reflective surface in order to reflect back radiation and thus further improve the insulation of the roof.
  • the mesh fabric expediently consists of polyester and has filaments with a diameter of 0.3-1 mm, in particular 0.5-0.8 mm, and a mesh size of 6-20 mm, in particular 8-12 mm.
  • the open-pore soft foam layer made of polyether polyurethane advantageously has a thickness of 2-12 mm, in particular 4-8 mm.
  • the film can be at least partially connected to the foam in the area between the filaments of a mesh of the mesh fabric. It is particularly expedient if soft foam, grid fabric and foils are connected to one another by flame lamination.
  • the sarking membrane can then be arranged directly on the rafters and the intermediate rafter insulation and fastened by means of counter battens.
  • the underlay can be arranged directly on the insulation boards.
  • the underlay 1 practically consists of three layers, namely the soft foam layer 2, the grid fabric 3 with the filaments 4 and the covering film 5.
  • the film 5 which expediently consists of polyurethane, has a thickness of 20-40 pm, in particular 25-30 pm.
  • the elongation at break is 550 - 600% and the tensile strength is 50 - 75 N / mm 2 .
  • the water vapor permeability - measured according to DIN 53122 - at 38 ° C and 90% relative humidity amounts to 350 g / m 2 d with a 30 ⁇ m thick polyether film or to 900 g / m 2 d with a corresponding polyether film.
  • the water pressure test according to DIN 53886 showed values of over 1500 mm WS (corresponding to 165 mbar).
  • the film can be equipped with fire-retardant additives.
  • the reinforcement 3 running below the film 5 consists of a lattice fabric or scrim, which can be produced by knitting, weaving, braiding, linking or coextrusion of intersecting filaments 4 and which is equipped with fixed or loose crossing points.
  • the mesh size is 6 - 20 mm, especially 8 - 12 mm.
  • the individual filaments 4 have a thickness of 0.3-1 mm, in particular 0.5-0.8 mm, with warp or weft, but also from individual threads in the form of tapes with a width of 0.3-3 mm, in particular 0.5-1.5 mm.
  • Open-pore polyether polyurethane flexible foams having a bulk density of 25-45 kg / m 3 , in particular 30-35 kg / m 3 , and a thickness of 2-12 mm, in particular 4-8 mm, are advantageously used as the foam web 2, according to DIN 53571 have a tensile strength greater than 85 kPA.
  • the air permeability should be 100 - 300 1 / min 100 cm 2 , in particular 160 - 200 1 / min 100 cm 2 at 10 mm water column pressure and 50 mm sample thickness.
  • the three layers, namely the film 5, the lattice fabric 3 and the foam sheet 2, are expediently connected to one another by flame lamination.
  • the filaments 4 of the lattice fabric 3 are partially embedded in the foam sheet 2 and the foils 5 are glued over the entire surface to the foam and at least in sections to the filaments 4 of the lattice fabric 3.
  • This increases the tensile strength of the underlay and makes warping due to folding or waves more difficult.
  • the diffusion of the water vapor is facilitated by the undisturbed transition area of the foils 5 between the mesh fabric 3 and the foam 2.
  • a special equipment of the three layers of the roofing membrane makes it possible to achieve fire resistance of building material class B1 or at least a building material class 2 according to DIN 4102.
  • Fig. 2 an application example of the sarking membrane 1 on a pitched roof is now explained in more detail.
  • the space between the rafters 6 is filled in full with insulating material 7, for example made of mineral wool.
  • insulating material 7 for example made of mineral wool.
  • a lamination in the form of a metal foil 8 can also be applied as a vapor barrier. But there is also one for this Layer or a material sufficient, the diffusion-equivalent air layer thickness is only 2 m.
  • the roofing membrane 1 according to the invention is now applied to the top of the rafters 6 and directly to the insulating material 7. This sarking membrane 1 is expediently nailed onto the rafters 6 by means of counter battens 9.
  • the sarking membrane 1 is expediently laid in rows from the bottom to the top of the eaves, a corresponding overlap being appropriate depending on the inclination of the roof. Because of the low vapor retarding effect of the roofing membrane according to the invention, it can then be installed continuously over the ridge.
