Definitions

  • the invention relates to a foam sealing tape, for example, for sealing between two structural parts, in particular between a frame member and the masonry associated therewith, wherein the sealing tape opposite, the building parts assignable broadsides and transversely extending to these narrow sides, wherein the sealing strip further from one of the narrow sides to the other, water vapor diffusion permeable is formed while forming a water vapor diffusion path, and further wherein the sealing tape has a barrier layer of a material different from the foam sealant material extending at least partially or completely across the cross section of the water vapor diffusion path.
  • the barrier layer is in this case usually arranged in the installation position of the sealing strip interior space to provide the sealing tape on the principle "interior space denser than room outside" (referring to the water vapor diffusion resistance of the sealing strip), so that there is a corresponding diffusion gradient due to the different water vapor diffusion resistance of the individual sealing strip areas and the water vapor entering the sealing band on the inside of the room can be removed from the sealing band towards the outside of the room.
  • the barrier layer may in this case be formed, for example, as a separate film or as a coating; EP 1 811 111 A1 . EP 2 309 090 A1 or DE 196 41 415 C2 or similar.
  • the sealing tape is intended to fulfill its function determination in different room climates in the interior as well as in different room outside weather conditions with respect to a discharge of water vapor to the room outside. Furthermore, it should be avoided that moisture accumulates in the sealing band area, for example at the sealing strip enclosing building parts, but is discharged as water vapor on the sealing tape to the room outside. As a result, for example, a condensation on the sealing tape enclosing component surfaces to be avoided, which could eventually lead to structural damage.
  • these requirements are only partially met by conventional sealing tapes.
  • the barrier layer has only a comparatively low permeability to water vapor, it is also possible for air humidity inside the room to be dissipated as water vapor only to a very limited extent via the sealing strip. If, on the other hand, the barrier layer has a comparatively high permeability to water vapor, there is the danger of condensation forming in the region of the sealing strip and thus of damage to the masonry, frame component or the sealing strip, especially in the case of very cold outside temperatures.
  • the DE 200 09 674 U1 describes a multi-layer sealing tape with several interconnected layers of foam, each with a different density, with an airtight barrier layer between two layers is provided.
  • the invention has for its object to provide a foam sealing tape, which at least largely avoids moisture accumulation in the region of the sealing strip even at low outdoor temperatures, but has sufficient water vapor permeability.
  • the barrier layer consists at least partially of a water vapor diffusion resistance (WDD resistor) with the humidity reversible changing material (the barrier layer thus increases the WDD resistance to the foam material, but this is still permeable to water vapor diffusion), with the further features of claim 1.
  • WAD resistor water vapor diffusion resistance
  • the barrier layer thus increases the WDD resistance to the foam material, but this is still permeable to water vapor diffusion
  • water vapor can pass through the barrier layer and the sealing strip controlled in dependence on the humidity. For example, if there is a relatively high humidity inside the room, the water vapor diffusion resistance of the barrier layer may change, for example decrease, so that moisture inside the room can more easily diffuse outward through the barrier layer and excessive humidity in the room can be avoided.
  • the water vapor diffusion resistance (s D value) of the barrier layer increases, for example, and less water vapor passes through the barrier layer from the inside of the room.
  • Existing moisture in the sealing band area for example on the sealing strip on its broad sides bounding component surfaces, can then be reliably dissipated via the sealing tape, since an additional loading of the sealing tape with water vapor from the room inside is limited by increasing the water vapor diffusion resistance of the barrier layer.
  • the moisture possibly accumulating on the parts of the building may in this case relate, for example, to condensation, but also to water absorbed in the masonry, for example in the case of structural parts made of porous material, such as porous rock, aerated concrete or the like.
  • These changes in humidity, which cause a change in the s D value of the barrier layer can occur depending on the time of day (change from day to night) or weather or Seasonal depending, so that over a certain period of time a removal of moisture present in the sealing tape area can be ensured by the barrier layer according to the invention.
  • the "broad side” is generally the sealing band side, which is designed or intended to bear against the components forming the joint.
  • the broadside usually has (but not necessarily) one greater width than the adjacent "narrow side". This can apply independently of each other for the fully relaxed state of the sealing strip or the arrangement within the joint, in which case a compression to 30% of the initial volume or the initial height of the fully relaxed sealing tape is used as a reference point.
  • the barrier layer is at least partially made of a material which reduces its WDD resistance with increasing humidity.
  • a material which reduces its WDD resistance with increasing humidity As a result, at relatively high humidity inside the room an undesirable accumulation of humidity in the interior of the sealing strip or on the adjacent thereto side surfaces of the building parts prevented and a controlled removal of humidity by diffusion through the sealing tape can be made possible.

  • the tape is only partially filled with the barrier layer, if the rev.WDD material does not have a WDD resistance which is too high, then it may be possible Water vapor diffusion through the sealing tape at least predominantly determined by the WDD resistance of the polymer material.
  • the water vapor diffusion can be essentially determined by the permeability of the remaining web (or generally non-barrier area), so that in this way, namely by properties of the barrier layer and its extent the Bandquerstreckung the WDD resistance of the tape is specifically adjustable.
  • the WDD resistors of a barrier layer at different humidities may be selected such that at the humidity with low WDD resistance (eg high humidity), the diffusion permeability of the barrier layer is substantially (eg predominantly) determined by the barrier layer (with), at high WDD resistance (eg at low humidity) in the same barrier layer then the diffusion permeability to a higher proportion, for example predominantly or practically completely by the barrier layer-free cross-sectional area of the sealing tape.

  • This material may for example also be layered and laminated with the position of the material with reversibly changing water vapor diffusion resistance or fill only the openings. In this way, for example, a minimum value of the water vapor diffusion resistance can be generated by the further layer with constant water vapor diffusion resistance, so that the sealing strip can be adapted to different requirements and ambient conditions.
