> I wish I could get those on my house for noise abatement. You can but your wall may not be thick enough. FWIW, you can get insulated glass where the different panes are different dimensions, which alone drops noise transmission a few dB (per literature). And using thicker (but not so thick as 6 inches!) creates a lot of reduction. I replaced the windows in my home office a few years ago and speced the outer as a laminate bandwidth with all three pieces different thicknesses (and not multiples of each other). It provided a considerable noise reduction though I can't attribute the amounts to the different composition vs thickness. Finding a glass company that was willing to completely replace the frames vs wanting to just take the glass out and put a 'frame in a frame'-- bad for appearance, thermals, and acoustics-- was harder than getting the unusual setup. I totally failed to find anyone willing to backfill with SF6+Ar. :P
