Definitions

  • the invention relates to a method for sealing during window renovation.
  • the old window frames are first removed from the brickwork, e.g. by means of a suitable window joint saw. Both the interior plaster and the exterior plaster along a straight, sharply defined edge of the old window frame is separated and then removed. This leaves the old disassembled window between interior plaster and exterior plaster a circumferential channel-shaped recess that extends to the raw masonry or even into this. Such recesses are different depths, usually between 10 mm and 100 mm.
  • window frames have a greater width than old window frames, so that when installing the new window, the window frame is no longer used in the recess, but remains outside of the recess.
  • the circumferential recess must be filled in the installed state of the new window with a sealing and insulating material, so that the space between the bottom of the recess and the new window frame is sealed in terms of good building insulation according to the generally accepted rules of technology.
  • the sealing tape again has a layer of flexible foam and a rigid layer.
  • the rigid layer to release the soft foam must not be destroyed, and the soft foam is disposed on the masonry facing side of the rigid layer.
  • the rigid layer is finally pre-assembled by means of various attachment mechanisms in profile channels of the window frame
  • the present invention has for its object to provide a method for sealing in the fenestration, with which the sealing of the new window frame in masonry can be ensured in an efficient and safe manner and can be performed at the same time in a simple way by the craftsman.
  • a complete and secure seal between the new window frame and old masonry resulting gap can be ensured. It is created a two-stage process, according to the first channel-shaped recess in the masonry is provided with a sealing tape, which is present during installation in the partially compressed state and only after the onset of the window frame expands against it. In addition, a fixed sealing depth is defined by the predetermined distance of the second layer from the open access section and thus also from the window frame to be used, which is to be bridged by the first layer.
  • the clamping function and handling of the sealing band are further improved by the fact that the second layer of the sealing band is formed from a rigid foam.
  • the second layer of the sealing tape is clamped to the side walls of the recess. In this way it is possible to achieve a secure positioning and fixation of the sealing tape in the recess without additional aids.
  • the second layer of the sealing tape has two predetermined bending points for defining two lateral clamping sections.
  • the clamping of the sealing tape in the recess is still wider area, when the two-sided clamping portions fold over when inserting the sealing tape in the recess in the direction of the open access section in the opposite direction.
  • recesses of different widths can be sealed with the same sealing strip, since the umklappenden clamping sections are suitable for bridging variable recess widths.
  • the second layer of the sealing tape can also be glued to the side walls of the recess.
  • an adhesive may be arranged on the side flanks of the second layer which come into contact with the side walls of the recess.
  • an adhesive may be on the sidewalls or certain sections be applied to the side walls of the recess.
  • the first layer and the second layer of the sealing tape are preferably firmly bonded together.
  • the first layer of the sealing tape is provided with a tacky impregnate which retards the recovery of the first layer after compression. In this way, the expansion of the first layer after the insertion of the sealing tape in the recess without additional aids and without complications delayed at least until the window frame is inserted.
  • the first layer of the sealing tape can also be at least partially surrounded by a film-like envelope which holds the first layer in the inserted state at least partially compressed, wherein after insertion of the window frame, the envelope is opened or removed.
  • a film-like envelope which holds the first layer in the inserted state at least partially compressed, wherein after insertion of the window frame, the envelope is opened or removed.
  • the predetermined distance of the second layer of the sealing tape from the open access portion of the recess is preferably 2 to 20 mm, more preferably 5 to 10 mm. Since the window frame is usually not arranged much more than 5 to 10 mm from the open access portion of the recess to lose as little window area, thus leaving a well-defined Abdichttiefe between the second layer of the sealing tape and the window frame, the first layer of the sealing tape must be bridged. This sealing depth can be easily sealed with conventional soft foam materials in compliance with the relevant standards with regard to driving rain and air tightness. On the other hand, in the space between the second layer of the sealing band and the bottom of the recess, care must be taken only for thermal insulation. This can be done by using a suitable insulating means or even with the help of the air contained in the space. When selecting the appropriate thermal insulation, the size of the gap plays an important role.
  • the sealing tape may comprise a third layer of soft, compression-recovering foam bonded to the second layer of the sealing tape at the second layer opposite the first layer, and after insertion of the sealing tape into the recess in the gap is arranged between the second layer of the sealing tape and the bottom of the recess.
  • this third layer is preferably at least partially compressed and expands after insertion of the sealing tape in the recess in the direction of the bottom of the recess.
  • This embodiment is particularly suitable for large spaces between the bottom of the recess and the second layer of the sealing tape. In this case eliminates the need for the introduction of an additional insulation in the space.
  • a compressible soft foam tape or polyurethane foam which is injected into the recess, come into question.
  • the first layer of the sealing tape in a specific embodiment, a plurality of three-dimensional foam segments, which by cuts, which are remote from the second layer of the sealing tape Extend from the top into the first layer of the sealing tape, are separated from each other, wherein the foam segments in the expanded state of the first layer over at least 50% of its height, preferably at least 60% of its height more preferably at least 70% of its height, more preferably at least 90th % of their height.
  • a plurality of notches preferably extends substantially parallel to the side walls of the recess, and another plurality of notches substantially perpendicular to the side walls of the recess, so that the foam segments have a rectangular basic shape.
  • the incisions may extend obliquely to the side walls of the recess, so that the foam segments have a diamond-shaped basic shape.
  • Other geometric shapes are conceivable, as well as the use of nubby foam.

  • the masonry 2 is formed in the illustrated example of a rough masonry 6 and attached plaster 8.
  • the recess 4 is channel-shaped and has a bottom 10, two side walls 12 and an access section 14 open to the outside.

In a preferred embodiment, the second layer 20 has a flexural strength of greater than 300 kPa, preferably greater than 400 kPa. In a particularly preferred embodiment, the second layer 20 has a flexural strength of greater than 500 kPa, preferably greater than 1,000 kPa, and more preferably greater than 2,000 kPa. simultaneously For example, the material of the second layer 20 must be elastic enough that it does not break during the use of the invention.

  • the bending strength of the material of the second layer 20 and the first layer 18 is determined in accordance with the standard ISO 1209-2, third edition from the year 2007. This international standard is commonly used to measure the flexural strength of plastics, but in a slightly modified form is also excellent for measuring the flexural strength of foams.
  • a uniformly changed force is applied in the middle between two supports perpendicular to a sample and thus bent through.
  • the flexural strength is calculated from the measured force / deformation curve (see Chapter 3 of ISO 1209-2).

In the illustrated example, the space between the two side walls 12 of the recess 4 is completely filled by the sealing strip 16.
  • the second layer 20 of the sealing tape must have such a width in each case and be designed so that it is supported in the absence of external influence on the side walls 12 of the recess 4 and preferably jammed without further aids.
