Definitions

  • the invention relates to a remedial vapor barrier for use in buildings, in particular for use in facades and / or renovation of building roofs, wherein the remedial vapor barrier a plastic film and a constant in the surface water vapor diffusion resistance, d, h. has a s d value.
  • Steam brakes are used, in particular, in the construction of new pitched roof constructions on a side of the roof construction facing the room, which i.a. from the rafters, preferably arranged between the rafters thermal barrier coating, arranged on the outer edges of the rafters underlay membrane and a roofing thereon arranged on the inner edges of the rafters and arranged on the disposed between the rafters thermal barrier coating.
  • the vapor barrier should prevent the ingress of moisture from the inside to the roof structure year round, since the moisture can lead to the formation of harmful condensation under the usually resting on the thermal insulation layer to achieve maximum thermal insulation underlay.
  • the vapor barrier is designed to be airtight.
  • the vapor barrier has an adapted diffusion resistance to water vapor to outside of the underlayment the formation of harmful condensation water, which u.a. to damage the insulation layer can lead to avoid.
  • the vapor barrier must be as open to diffusion as possible, at least in the area on the top of the rafters.
  • a vapor-permeable vapor barrier would in turn lead in the area between the rafters to an overall low diffusion resistance through the usually encountered inner lining of plastered Holzwollebachplatten or blankets that allow harmful dew formation in the heat insulation or below the underlays would.
  • the moisture-adaptive vapor barrier can not be used in areas above rooms with permanently high air humidity, since there the diffusion resistance occurring at the vapor barrier would constantly be too low.
  • Another redevelopment solution is the DE 201 20 812 disclosed. This provides that individual strips of a vapor barrier are laid parallel to the rafters, wherein each vapor-permeable and diffusion-tight vapor barriers are arranged alternately in such a way that the vapor-permeable strips lie on the rafters and envelop him and the diffusion-tight strips are disposed between the rafters and rest on the interior trim. To produce the airtight connection while adhesive strips are used.
  • a particular disadvantage of this solution is the difficult installation and the overall increased installation effort compared to a one-piece vapor barrier.
  • the diffusion-proof strips must each be adapted to the existing rafters distances, which can vary greatly for old buildings in particular.
  • a one-piece vapor barrier known, which is also laid parallel to the rafters and thereby has contiguous areas, each with deviating diffusion resistance.
  • a vapor barrier has the disadvantage that it is not adaptable to different rafter distances. A usability is usually only given in new buildings, where constant rafter distances are to be found.
  • vapor brakes for the renovation of old roofs with a constant s d value of at least 2 m are available on the market. These represent a compromise between the required water vapor impermeability in the rafter field and the water vapor permeability in the area of the rafters and can be laid without any problems.
  • An s d value of at least 2 m is given in the general state of the art as an absolute lower limit in order to avoid condensation on the underside of the underlayment.
  • the product "DELTA LUXX" from Ewald Dörken AG may be mentioned here.
  • the invention has for its object to provide a San istsdampfbremse with a constant in the surface water vapor resistance, which can be used in particular for the renovation of externally accessible building roofs and easy to install and a harmful condensation in the area above the vapor barrier and a harmful moisture content of the Rafter prevents.
  • the invention solves the problem by a remedial vapor barrier with the features of claim 1.
  • Advantageous developments of the remedial vapor barrier are given in the dependent claims 2-13.
  • Characteristic of the remedial vapor barrier according to the invention is that the constant water vapor diffusion resistance (s d value) of the remediation vapor brake assumes a value of 0.6-1.7 m. All s d values stated in the application refer to the DIN 52615 standard valid for their determination (boundary conditions: 23 ° C, 0/85% relative humidity).
  • the rehabilitation steam brake according to the invention thus allows a simple rehabilitation of pitched roofs, wherein the sanitation vapor barrier is guided in a simple manner looped over the rafters and the rafter field.
  • the sanitation vapor barrier according to the invention is not limited to use in the case of roof renovation, but can equally be used for the renovation of truss walls or for the construction of pitched roofs or even in wooden studs in the outer wall, in which case the advantage is that an accelerated dehydration of Moisture or new building moisture in the truss as well as new building moisture in the pitched roof is favored.
  • the renovation steam brake according to the invention can be produced particularly cost-effectively and thus contributes to the reduction of total rehabilitation costs when used as a rehabilitation steam brake.
  • the remedial steam brake has a constant s d value from the interval of 0.6-1.7 m.
  • the remedial vapor barrier has a constant s d value from the interval 0.8-1.6 m, in particular from the interval 1-1.5 m.
  • the remedial steam brake can in principle be made of any suitable material for this purpose and be formed in one or more layers.
  • the redevelopment vapor barrier can possibly also be formed by a reinforcing layer combined with the functional layer, which improves the mechanical properties of the redevelopment vapor barrier.
  • the s d value of the regeneration vapor barrier depends primarily on the material used for the production. However, the s d value can moreover be adapted in a simple manner, for example by the use of additives, such as suitable fillers or fibers, certain production methods, such as partial stretching or else by setting a suitable porosity. As materials, for example, special paper stocks, modified papers or the like can be used. However, the required porosity may also have purely fibrous structures, which may be nachkalandriert if necessary.
  • the remedial vapor barrier on a plastic film which is particularly simple and inexpensive with known methods can be produced.
  • the redevelopment vapor brake developed in this way can be extruded, for example, or produced by an extrusion coating.
  • the remedial steam brake can be produced by gluing individual layers, brushing on, for example, pastes, roll coating, spraying or calendering.
  • plastics it is possible to use those materials which make it possible to produce the renovation steam brake with the features according to the invention.
  • polyethylene copolymers, polycarbonate or polyvinyl chloride are suitable for the preparation.
  • the plastic film in the extrusion process of modified polyethylene particularly advantageously made of ethylene vinyl acetate copolymer.
  • the renovation steam brake according to the invention which can be supplied as a film, tarpaulin, fabric, non-woven or the like, particularly easy to lay.
  • the sanitation vapor barrier is flexible, foldable and / or rollable.
  • a supplementary facilitation of the laying of the remedial vapor barrier results according to a further advantageous embodiment of the invention, according to which the remedial vapor barrier is partially self-adhesive, in particular has a self-adhesive.
  • the connection to the rafters or an existing interior trim in the case of use as a remedial vapor barrier is particularly facilitated.
  • the connection of adjoining remedial vapor barriers in the overlapping area can be substantially simplified.
  • this can advantageously have a reinforcement, which is formed in particular from a grid, a woven fabric, a scrim, a knitted fabric and / or a nonwoven structure.
  • the reinforcement can also be formed by fibers or filaments embedded in the remediation vapor barrier. The reinforcement improves in a complementary way the tear and tear strength of the renovation vapor barrier and also prevents damage due to punctures. The reinforcement is embedded in the remediation vapor barrier.
  • the remedial vapor barrier may also be applied to a carrier layer, which is preferably formed from a woven fabric, a needle felt or a thermally bonded nonwoven.
  • a carrier layer which is preferably formed from a woven fabric, a needle felt or a thermally bonded nonwoven.
  • this can also fulfill functional properties and thus increase the range of application of the remedial vapor barrier in a complementary manner.
  • the remedial steam brake is advantageously carried out according to this embodiment of the invention by extruding the plastic film onto the selected carrier layer.
  • the remedial vapor barrier additives u.a. determining the color, the fire behavior and / or the aging resistance.
  • suitable stabilizers e.g., UV or thermal stabilizers
  • colorants and color pigments, flame retardants, and other fillers or fibers may be used.
  • the supply of additives according to this embodiment of the invention makes it possible to make an optimal adaptation of the sanitation vapor barrier to the intended use.
  • Fig. 1 shows a section of a cross section through a roof truss 1 with two adjacent rafters 2 and a rafter field lying between the rafters 2.
  • an inner lining 4 is arranged with an attached decorative layer 5 from an inner side of the roof truss, wherein the inner lining 4 directly adjacent to the rafters 2.
  • a San istsdampfbremse 3 looped over the outside and side surfaces of the rafters 2 and in the area of the rafter field on the outside of the inner lining 4 arranged for renovation purposes.
  • the remedial vapor barrier 3 consists of an extruded film with a basis weight of 52 g / m 2 and the following recipe: 89% ethylene-vinyl acetate copolymer with 28% vinyl acetate, 4% carbon black based on LDPE with 50% carbon black and 7% flame retardant based on of LDPE with 70% active substance (mixture of chloroparaffins and antimony trioxide).
