Soundproofing wooden frame+single pane windows
« on: July 15, 2008, 02:09:12 PM »

I want both high(shouting) and low(diesel truck) frequency noise be lowered at my outer windows. I have a couple of questions.
*Unfortunately, we don't have Magnetseal or such ready-to-use products here. Can I make those kind of things myself? Is it going to work?
*Will listening to the frames or walls by a stethoscope help finding the spots where most noise leaks? Or will it just confuse and misdirect?
*How much noise does the wooden frames themselves absorb? If none(or near none), I'll replace whole windows with vinyl ones. But how should I specify vinyl frames? What should pane thicknesses be? Besides, should I treat frame-wall seams or frame-frame seams specially? How much noise goes through the seams and how much through the surfaces?
Thanks in advance.

Most replacement window installers leave a gap around the new window assembly and then stuff it with fiberglass or foam-in-a-can - or they just leave the gap and cover it with molding.  Neither of these is good - leaves an open sound path for noise to come right through.  Closed cell backer square tape and acuoustic caulk work best to seal this gap.
Check out the STC ratings of any replacement windows.  Here are two companies to check out, one metal or vinyl clad and one wood:
For do it yourself magnetseal materials just order off the web site at

Using a stethoscope may work well to determine where are sound problems.  You can also just use your finger tips to test for vibrations.
