A roof window with an acoustic laminated vacuum insulated glass unit

Abstract

The invention relates to a roof window comprising a frame and a laminated vacuum insulated glass (laminated VIG) unit fixed in said frame, the laminated VIG unit comprising: a first glass sheet and a second glass sheet, wherein the first and second glass sheets are separated by an evacuated gap, and wherein a plurality of support structures are distributed inside the evacuated gap between the first and second glass sheets, a lamination layer arranged between the first glass sheet and a further sheet, said lamination layer is bonding to an outer major surface of the first glass sheet facing the evacuated gap, wherein the lamination layer comprises at least a first layer and a second layer of a polymer material, wherein, when the roof window is exposed to impacts; the fluctuation in decibel (dB) over a range of 1000 Hz in the interval from 20 Hz to 13000 Hz will not exceed 10 dB.
