I'm constructing a room in the crawl space of my house, that will be used in part for a home theather, and I want to make it as soundproof as possible. This room will have one 5040 window. Home Depot tells me that they can supply windows that have 3/16" or 1/4" thick panes, as opposed to the normal
1/8". I'm wondering if any one has experience or information as to the soundproofing effectivesness of these thicker windows?One alternative I have considered is to frame the window opening using 2x4's in the 2x6 wall and installing a regular 1/8 pane window as normal. Then installing a second window on the inside of the 2x4 opening. this would leave an approx 2" airspace between the two windows, which could present a cleaning problem with the inevitable collection of dust in this space, (the windows are going to be sliders), and it might look a little weird. If the thicker panes are substantially effective, I think I'd would rather go that route because of the normal appearance.
I'd apprecite any comments on the thicker pane windows or the double window arrangement, and any other suggestions as to how to make this window as soundprrof as possible.
TIA Kevin
