I would like to noiseproof my den. In a previous house I did this by
installing aluminum dual tracks around the inside perimeter of the
existing
window opening and by then inserting a sliding window panel in each track.
In effect, this provides dual-pane windows for noise control.

Does anyone know where I can buy this system, or something similar, in the
South-Western US? I tried local glass shops in San Diego without luck.

Don't know, but you might want to check out Milgard Windows. They make the
best windows in S. CA, and since I put them in, my house has been silent as
a tomb.
