Definitions

  • the invention relates to a Unterdeckbahn for a sloping roof with a water and water vapor permeable support layer and a waterproof and wasserdampf emphas-sigen sealing layer based on TPU. Furthermore, the invention relates to a roof with a plurality overlapped laid and welded, waterproof and water vapor permeable underlay webs.
  • Underdecks have the task of initially protecting the uncovered roof from rainfall. After the hard roofing, the input of flying snow, spray and condensation water and fine dust particles in the thermal insulation should be prevented. At the same time, water vapor, which can originate as a wet surplus from the building moisture and from inhabited areas of the roof, can be released to the environment via the diffusive heat insulation and the underlay membrane. In this case, the entire, mounted between the rafters thermal insulation can serve as a temporary moisture storage, it should be noted that the dew point at which condensation is deposited, is not exceeded. This can be prevented by installing a vapor barrier or brake under the roof into the roof construction.
  • the laid underlay membrane has no or too little permeability to water vapor, there may be a moisture surplus in the roof area on the underlay membrane condense, moisturize the insulation and thus, inter alia, reduce their function.
  • underlay membranes For underlay membranes, a distinction is made among other things between waterproof underlay membranes and rainproof underlay membranes.
  • rainproof roof coverings are as a rule rainproof, they can not completely prevent the input of driving rain and driving snow in extreme locations or in special weather conditions.
  • a sub-roof is considered to be rainproof if its surface, including the seam and butt joints between individual roofing membranes, is rainproof. In the rainproof under-roof penetrations, built-in parts and borders are rainproof.
  • plastic sheets are used to produce a watertight underlay, in particular TPUs, ie urethane-based thermoplastic elastomers, because they are particularly water and heat-resistant, soft and flexible, therefore easy to process and, in particular, resistant to microbes.

  • plastic sheets are used to produce a watertight underlay, in particular TPUs, ie urethane-based thermoplastic elastomers, because they are particularly water and heat-resistant, soft and flexible, therefore easy to process and, in particular, resistant to microbes.
  • TPUs ie urethane-based thermoplastic elastomers
  • sealing layer is, in addition to the waterproofness, the water vapor permeability, which is also referred to as diffusion openness. This means that although the sealing layer is impermeable to water which may strike the underlay from the outside, water vapor from the interior of the building can escape to the outside due to the diffusion-open nature and thus an impairment of the thermal insulation or of other objects present in the interior of the building avoids too high humidity.
  • the underlay webs often still have a carrier layer, which is permeable to water and water vapor.
  • a layer composite of a carrier layer and a sealing layer can be waterproof and permeable to water in a watertight and water vapor-permeable sealing layer as a whole, so that a vapor-permeable and watertight embodiment of a sub-roof can be realized.
  • US 2005/0097857 A1 discloses a non-asphalt, especially non-bitumen, underlay for a roof that is vapor-permeable and waterproof.
  • One or two layers of a vapor-permeable thermoplastic material can be applied to a substrate layer.
  • DE 38 23 365 A1 discloses a roof covering element in the form of a rectangular insulating panel made of heat-insulating material, which serves to shorten the assembly time on site a serving for sealing the roof sealing membrane directly on the top of the insulation board is laminated.
  • the sealing sheet is for sealing connection with the adjacent insulation boards on two adjacent edges on the insulation board over.
  • the underlaid webs known from the prior art have the disadvantage that they can be connected to one another in a watertight and permeable manner only with relatively high outlay.
  • additional adhesives must be provided for the watertight and diffusion-open connection between underlay webs with a TPU-based sealant layer.
  • the TPO-based weldable underlay membranes do not have the advantages of the TPU layer, which includes the special water and heat resistance, the soft and flexible structure and therefore good processability and microbial resistance.
  • the object of the present invention is to provide a sub-roof sheet associated with the above technical field, which enables an efficient realization of a watertight and water-vapor-permeable sub-roof.
  • a underlay for an inclined roof with a water and water vapor permeable support layer and a waterproof and water vapor permeable sealing layer based on TPU characterized in that the thickness of the sealing layer is dimensioned such that the underlay web with another similar underlay by thermal welding and solvent welding is waterproof and permeable to water.
  • the underlayer web has a watertight and water vapor-permeable connection strip along at least one of the edges of the carrier layer, which projects beyond this at least one edge, and both the TPU of the sealing layer and the TPU of the connection strip is an aromatic TPU.
  • An inclined roof is understood to mean a roof which, according to DIN 1055, has a slope of more than 7 degrees. Despite the inclination of the roof, it is advantageous or even necessary for certain weather conditions to provide not only a rainproof, but a waterproof underlayment to effectively prevent driving snow, driving rain, icing and snow deposits and the like.
  • the waterproof and water vapor permeable TPU is used which has the advantages already mentioned above.
  • TPU within the meaning of the invention are also mixtures with a share of at least 80 wt .-% TPU and up to 20 wt .-% filler count.
  • Corresponding fillers can be used for example to save material and / or cost reduction.
  • the standard to be considered for diffusion openness is DIN 4108, Part 3.
  • Sd ⁇ 0.5 m is defined as the limit value for diffusion openness.
  • a layer whose Sd value is less than 0.5 m is to be designated as diffusion-open.
  • the Sd value is preferably less than 0.2 m. According to DIN 68800, Sd ⁇ 0.2 m must be adhered to and a corresponding layer must be regarded as permeable to vapor if chemical wood preservatives are to be dispensed with.
  • the Sd value of the underlay web is less than 0.2 m and is between 0.02 m and 0.2 m.
  • THF tetrahydrofuran
  • benzene or gasoline can be used.
  • THF is particularly preferred over benzene or gasoline or other solvents due to its short exposure time and associated short time required for laying.
  • Preferred solvents may generally be included among the alkanes, alkenes, aromatics, organochlorine compounds, alcohols, esters, ethers or ketones.
  • the underlay of the invention preferably consists of a water- and water vapor-permeable support layer and a waterproof and water vapor permeable sealing layer and requires neither an additional adhesive layer as a connecting means with another underlayment still another, the stability of the underlayer web increasing layer.
  • the support layer provides for the stability of the underlay web, whereas the sealing layer is responsible for ensuring that the undercover web is waterproof and permeable to water vapor.
  • the material used for the sealing layer based on TPU is relatively expensive, so that conventionally care is taken to make the sealing layer as thin as possible in the context of the requirements in terms of their sealing property.
  • the thickness of the sealing layer is increased so much that thermal welding is also possible with a sealing layer based on TPU, without the sealing layer or the carrier layer being damaged during thermal welding. This would be done in the case of a conventional underlay web with a correspondingly thin sealing layer, so that conventional underlay webs by thermal welding can not be connected.
  • the waterproof and water vapor-permeable connection strip according to the invention is provided along at least one of the edges of the carrier layer, which protrudes beyond this edge.
  • connection strip can, for example, be placed on hot TPU during production of the underlay web, which is already located on the carrier layer, and thereby connects to the TPU of the sealing layer.
  • the connecting strip is made integral with the sealing layer, that is, the sealing layer as such extends correspondingly over at least one of the edges of the carrier layer such that a corresponding connection strip is formed.
  • there are other ways to connect or create the connection strip with the underlay web e.g. by removing cover layer material or removing backing layer from the underlay web.
  • the connecting strip is also made of a waterproof and water vapor permeable material, it is possible waterproof and water vapor permeable together assemble a lower cover sheet with another Unterdeckbahn, so that a sub-roof can be made completely waterproof and permeable to water vapor.
  • the connecting strip as part of the underlay web allows a particularly efficient connection between adjacent underlay webs, because here no additional adhesive or another connecting element has to be placed on the adjacent underlay webs.
  • connection strip is a TPU-based strip.
  • the TPU-based connection strip also provides watertight and water-vapor permeable roof coverage at the welds with all the advantages of the TPU and facilitates the welding of adjacent underlay webs.
  • Both the TPU of the sealing layer and the TPU of the connecting strip is an aromatic TPU, wherein preferably the sealing layer and the connecting strip are made of the same material.
  • Aromatic TPU is particularly well suited for welding and has the above-mentioned particularly preferred properties of a TPU-based sealing layer.
  • the sealing layer has a thickness of at least 0.1 mm, preferably 0.1 to 0.2 mm, particularly preferably 0.1 to 0.15 mm.
  • a thickness of the sealing layer of the underlay web is suitable for connecting adjacent underlay webs to one another by welding, without the sealing layer and / or the carrier layer being damaged in the process.
  • the claimed thickness is at the same time suitable for the efficient production of a underlay web, since no excess material is applied to the carrier layer.
  • the sealing layer has a mass areal density of at least 100 g / m 2 , preferably 100 to 200 g / m 2 , particularly preferably 100 to 150 g / m 2 .
  • Corresponding mass surface densities mean that, compared to conventional sealing layers of a lower cover sheet of the preamble of claim 1, a mass application has taken place which makes adjacent lower cover webs connectable to one another by thermal welding or solvent welding.
  • the underlay web is adhesive-free.
  • some kind of adhesives are required in order to bond the underlay membrane to an adjacent underlay membrane.
  • welding is occasionally used in the prior art, this is in fact bonding, since it is not the TPO layers of the corresponding sealing layers that are connected directly and directly to one another, but an adhesive is incorporated into the underlay web is that optionally produces a watertight connection between adjacent Unterdeckbahnen.
  • the connecting strip protrudes by at least 3 cm, preferably by between 3 cm and 7 cm, particularly preferably by between 5 cm and 7 cm beyond the at least one edge.
  • a connecting strip which extends beyond the edge by the above-mentioned value, allows a secure connection between adjacent underlay webs, so that the entirety of the underlaid webs can be made waterproof and permeable. It thus meets the building supervisory requirements for a watertight welding of two underlay membranes with each other.
  • the connecting strip is made integral with the sealing layer.
  • a connection strip is laid on the hot TPU, for example during the production of the underlaid web, or produced as a part of the sealing layer projecting beyond the carrier layer.
  • connection strip is joined to the sealing layer by thermal welding and / or solvent welding.
  • the connecting strip can be connected after cooling of the sealing layer with the sealing layer.
  • the connecting strip can thus be connected by the same mechanism with the sealing layer, as adjacent lower cover webs can be interconnected.
  • existing underlay webs with a corresponding thickness of the sealing layer can also be retrofitted with a connection strip according to the invention.
  • the laying of the underlay web is simplified because the connecting strip only needs to be welded to one edge of a underlay web and not with two abutting edges of two underlay webs.
  • the carrier layer is preferably a nonwoven.
  • the basis of the nonwoven may preferably be polyester or a polyester-containing mixed fiber or a derivative thereof.
  • a carrier layer of nonwoven makes possible a particularly simple production of the underlaid web, in that the sealing layer can be applied to the then existing carrier layer without the sealing layer itself having to be particularly stable. This also allows large-area underlay webs to be efficiently produced.
  • the carrier layer of occupational safety when laying the underlay sheets because it brings an additional strength in the underlay, so that the underlay can easily carry an adult human, when this occurs on the underlay.
  • the underlay web according to the invention can be used for all applications which require watertight and water-vapor-permeable undervoltages.
  • the underlay sheet according to the invention enables a particularly efficient laying of a lower roof as well as an efficient production of the underlay sheets.
  • Adjacent underlaid webs can be directly connected to one another by means of the connecting strip, whereby they are also watertight and permeable at the point of connection, namely the overlap between the connecting strip and the adjacent underlaid web.
  • the underlay web has more than two layers, wherein it is preferred that it contains only one carrier layer and one sealing layer. Depending on the field of application, however, it may be advantageous to provide one or more further layers either on the sealing layer, between the sealing layer and the carrier layer or under the carrier layer. In order to ensure the waterproofness and diffusion-openability of the underlay web in a multi-layered design, however, care must be taken to ensure that the additionally attached layers are at least permeable to water vapor and do not impair the watertightness of the sealing layer.
  • the underlay web according to the invention can also have a plurality of connecting strips which project beyond a plurality of edges of the carrier layer. This can be provided, for example, in corner pieces of underlay sheets or in special undercover elements for sealing penetrations, built-in parts or enclosures.

  • the connecting strip of a bottom cover web is welded to an adjacent bottom cover web in such a way that the bottom cover webs have a watertight and water vapor permeable welded connection.
  • the connection strip is preferably formed integrally with the sealing layer of the associated underlayment, so that welding only has to take place on one side of the connection strip.
