Sealing-insulating tape, especially for windows and doors and method for manufacturing the sealing-insulating tape

摘要

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 ).
