Abstract
A method according to this disclosure includes stacking a first glass sheet, a first interlayer, a film, a second interlayer, and a second glass sheet to provide a lamination stack, wherein the film has a first film edge that is a first distance from a first edge of the lamination stack to provide a first film cutback; deairing the lamination stack; and autoclaving the lamination stack to provide the laminated glazing, wherein the film shrinks during autoclaving wherein a seal formed during deairing is sufficient such that no air is introduced to the lamination stack during autoclaving and no air is left in the laminated glazing.
