Secondary Glazing

We'd like a quote for Secondary Glazing to be fitting in the interior of our Aluminium bedroom window. The bedroom is facing a road and would like to get a sliding Secondary Glazing unit fitted to help with soundproofing the room. The dimensions of the internal window frame are 136cm H x 136cm W. We'd like some recommendations on units to install; The main reason is to act as a sound barrier from the road/noise pollution from outside. Please refer to attached photo for picture of window/frame.
