Stopping "resonance" from dual pane wind
« on: October 15, 2003, 04:27:42 PM »

I just replaced my old wooden single pane windows with dual pane 1/8" over 1/8" vinyl Milgards and what used to be a distant waterfall sound of rushing traffic through the old windows is now causing a kind of "resonance" thru the dual pane units- it can vary but usually sounds like a buzzing bee's nest or truck tires buzzing on a freeway.  I also notice that in general the windows seem to ring like a crystal wineglass in response to lots of noises (refrigerator running inside, weed whacker running across the street, etc.)  In many ways my old windows were actually better.  I always thought dual pane units would improve the noise, not the other way around.  I was wondering what the remedy to this is (other than getting a whole different set of windows!)

Sir,

I feel your pain - I replaced old single pane + storm set up w/ brand new vinyl dual windows.  Cost me approx $ 4 K for 12 new windows and thought I was smart.  The noise is now approx 2 x worse than I can ever recall.  Not sure what to recommend as I have tried and failed at a few attempts.  

I would love to hear of anyones success w/ laminated glass inserts or magna seal window inserts.

Basically, you are not going crazy.

Regards,

Michael

Dear Tom Garvey,
Did you install regular Milgrad windows or Milgrad "quiet line" series?

The way to stop resonance in a window 'cavity' is the same way in a wall - add absorbtive insulation inside the cavity.  Or you can increase/decrease the mass of one of the windows to change the coincidence-frequency.  I'm not sure how practical either of these suggestions are, but those are basically the ways you can do it.
