We adore how the ceiling curtain track concept has been used to separate the space and imitate a completely private movie theatre.
The sound of the movie room can be insulated and the necessary light block out can be provided by hanging thick curtains across the room entrance from the ceiling to the floor.
Additional ceiling curtain tracks or the DartAnt Homes Flexible Curtain Track system with heavy curtains installed along all of the cinema room walls would improve the theatre-like atmosphere.
