Good soundproofing windows?
We moved into a house that is located on a somewhat busy street and want to replace or soundproof/insulate the original, 1870 bedroom windows. If we replace the windows we'd like to keep the feel of wood on the inside at the very least. We are more concerned with soundproofing capabilities then heat insulation. I have heard of soundproofing systems like Soundproof Window (http://www.soundproofwindows.com/) but they don't seem very esthetically pleasing. Do any replacement windows have good soundproofing qualities?
Any help appreciated!
