Laminate glazing comprising a perimeter stepped element of a polymeric material having the maximum permeability required for water vapor

摘要

The present invention relates to: - at least one first glass sheet (1) constituting the outer surface of the laminated glazing and connected to a second glass sheet (3) by a first interlayer adhesive layer (2); The edge is retracted with respect to the second glass sheet 3 , the periphery of the free surface of the first glass sheet 1 , the edge surface of the first glass sheet, the edge surface of the first interlayer adhesive layer 2 and the first glass The part of the surface of the second glass sheet 3 extending beyond the sheet 1 is covered, via an adhesive 6 , with a stepped element made of a polymeric material which may contain reinforcing fillers, up to 5 g/m Laminated glazing with a continuous stepped profile showing a permeability to water vapor of ^2/day; - its manufacturing method; - its use (aviation, etc.).
