Insulating glass with improved impact resistance

摘要

The present invention relates to an insulating glazing (1) comprising an assembly of parallel glazing, two consecutive glazing units in the assembly being separated by a cavity (4) containing a gas layer, said insulating glazing (1). ) comprising at least one laminated glazing (3), characterized in that the at least one laminated glazing (3) comprises two sheets of glass (5a, 5b) between which is laminated an intermediate adhesive layer (6), the layer interlayer adhesive (6) having a basis weight of between 843 g / m² and 1211 g / m², the value of the adhesion glass-interlayer adhesive layer measured by the TCT method at 33 mm.s-1 and 20 ° C being less strictly at 20 kJ / m2.
