Secondary Glazing

Has anyone ever looked into 2nd glazing for sound reduction. I live on a busy street in Chicago and was trying to reduce the noise level. I have deep sills inside and have plenty of room for this but b4 I spend the money I would like a little feed back on what people think. The windows are double pane already and 2 yrs old vinyl. I was wondering if anyone has done this and saw some benefits. Thanks

Since you already have dual pane vinyl framed windows, look at other areas to reduce the noise. You're not going to do too much to them that will reduce the noise appreciably.

What kind of siding do you have? Something like wood, 3 coat stucco, or cement fiberboard siding that is attached directly to the outside of the studs and sheetrock that is attached directly to the inside of the studs is going to transfer a lot of street noise. Installing a siding that uses a 3/4" or 1" foam backing (like vinyl or foam core stucco) will reduce the noise level along with adding insulation to your walls.
