These panels will block about 30 dB of the street noise..

The Window Noise Block Panel is made out of reinforced heavy limp mass barrier core ( MLV core) with Producer’s Choice Sound Blankets and Ballistic Nylon. Blanket should be facing into the room)..

If you experience issues with noise coming through the windows the first thing to do is to seal the gaps around the frame and make sure the window is shut tightly. Then hang the Window Noise Blocking Panel, flush with the window frame, to significantly improve the sound transmission loss.
NOTICE: the panel is very heavy.  it has grommets at the top so you can hang it on the nails or screws.
