The building is concrete with a dryvit styrofoam facing, so I think that's doing a fine job of noise reduction. The bulk of the noise seems to be coming through the sliding glass doors at the south end of the unit. One in the master BR and one in the LR.
These glass sliders look to be cheap builders grade low cost doors. They slide fine, don't leak in storms, and generally work ok, but they are your basic 6' sliders. I want to keep the glass doors because they connect to the balcony, let in light, and give nice views.
Should I look into buying new glass doors? Do I go top of the line name brand from the local vendor, or are some better than others?
I did read that adding a 2nd door outside the original will help, but I'm not sure I want that drastic of a solution.
What about rolling blinds? The kind that roll up into an exterior box at the top of the window. Will these just block light, or do they actually help with traffic noise.
I'm sure there are other folks who have similar issues, how did you solve them?
