Abstract: The self-adhesive tape for closing, sealing and gluing of joints in corners and edges, between framework window/door frame, and facade/roof openings during housing construction, comprises a perforated carrier layer (1) at the tape upper side, a pressure-sensitive adhesive coating (2) of a part of the carrier layer at the tape lower surface, and a removable surface coating film (3) of the pressure-sensitive adhesive coating at the tape lower surface. The tape exhibits a perforation region (4), edge region and a strain-resisting element. The self-adhesive tape for closing, sealing and gluing of joints in corners and edges, between framework window/door frame, and facade/roof openings during housing construction, comprises a perforated carrier layer (1) at the tape upper side, a pressure-sensitive adhesive coating (2) of a part of the carrier layer at the tape lower surface, and a removable surface coating film (3) of the pressure-sensitive adhesive coating at the tape lower surface. The tape exhibits a perforation region (4), edge region and a strain-resisting element. The strain-resisting element is a pleated-folding of the tape, is separated from the tape of the perforation region in the transverse direction and is centrically arranged when seen from the transverse direction of the tape. The perforation region of the tape exhibits perforation openings with an average diameter of 3 millimeters. The perforation openings (5) pass through the carrier layer, the pressure-sensitive adhesive coating and the removable surface coating film and are round, angular or oval. A center section of the tape is non-adhesively formed, without pressure-sensitive adhesive coating and/or pressure-sensitive adhesive coating of another part of the carrier layer. A first folding section of the tape is folded in the transverse direction along a first folding edge that runs in the longitudinal direction of the tape. The first folding section is the section facing the perforation region. A second folding section of the tape is folded in the transverse direction along a second folding edge that runs in the longitudinal direction of the tape. The surface coating film exhibits a first and second slot in the longitudinal direction of the tape. The second folding edge falls in place with the second slot of the surface coating film. An edge section of the surface coating film stands above the first folding edge and/or the second folding edge. The first and second folding sections are partially superimposed. The tape lower surfaces and the tape upper sides are superimposed. The pressure-sensitive adhesive coating is not covered within the region of the first folding section and/or the second folding section with the surface coating film. The thickness of the pressure-sensitive adhesive coating is smaller than 0.3 mm. An intermediate layer is intended at the side of the first folding edge of the roll. The carrier layer is rolled up to a tape roll in the folded condition and is rolled up to 4.5-20 cm in the non-folded condition. A side of the carrier layer is composed of open-porous material. The tape exhibits a first and second diffusion-open tape section and a first and second diffusion-closed tape section, following the perforation region in the transverse direction.
