The client lives near a noisy (and busy) set of train tracks. These glass sliding doors, in addition to her standard double-pane, double hung windows, were a major source of sound infiltration into her home. Climate Seal Acoustic Series inserts were chosen to drastically reduce her sound problem that was attributable to the doors and windows.
The acoustic inserts were divided aesthetically with a vertical mullion that aligned with the door frame. The passive door slides from right to left.
