Use
Acoustic windows are used in all types of buildings where noise reduction is required or desired, and which cannot be achieved with ordinary acoustic glass.
Function
Acoustic windows are constructed as top guided, side hung and side swing windows with an inward opening secondary sash. The external sash is locked with a handle that operates a multi locking point hook bolt mechanism and has a night vent position. The handle also operates a friction brake to hold the sash whilst in the open position. The secondary sash is operated with a small locking mechanism which holds the sash closed.
