| (54) | Flashing tape, in particular for windows and doors and method of flashing tape production |
| (57) The subject of the invention is a flashing tape, in particular to be used as a seal
and insulation of the gap between window or door frame and a wall, and the method
of the flashing tape production. The tape according to the invention consists of at least two stripes of compressible insulation foam (1) and (1.1) made of plastic, covered with a vapour barrier layer (12) on one side at least, attached on both sides to the stiffening tape (2). The stripes (1) and (1.1) are compressed in the direction crosswise to the stiffening tape (2) by means of at least one protective film (3) which is a perforated vapour-permeable film (5) and (5.1). The film is joined to the edge of the stiffening tape (2) in connection spots (6) or in points (7) and (7.1) if it is made of two film stripes (3) and (3.1). The protective film (3) of variable permeability for water vapour depending on air humidity is joined in place (4), whereas the stiffening tape (2) is more flexible in the longitudinal direction than crosswise. The stiffening tape (2) may be made of different materials, the same applies to stripes of compressible insulation foam (1) and (1.1) and a vapour barrier layer (12). |
