Traffic Noise
« on: April 23, 2014, 02:05:35 AM »

We have a 23 year old house with 23 year old double pane windows. We have a road 100 feet from our front door that has seen a change in traffic patterns and a  two-fold increase in traffic over the last 2-3 years. The speed limit is 40 MPH so we now have a pretty constant stream of cars flying by at 60 MPH plus from about 7 am until about 10 pm or 11 pm. We don't much notice the noise when downstairs but at night we can count the cars zooming by (not to mention the trucks and motorcycles) in the upstair's bedrooms.

I've been looking around the internet for a fix to our sound problem --still not sure which way to go. Do we replace our 23 year old  windows with a better quality replacement window that will solve our sound problem? Do we do an insert window? Is there any other option? From what I understand there would be no use to installing a window with a higher STC rating than our walls --but how do I know what the rating would be for our house and that the windows are the problem ? Also I am not sure of the rating for the windows we have already. Would it be worth it to spend the money for replacement windows if they can only chop the sound down by  20%. Actually I wouldn't mind trying the insert windows on a limited basis in the upstairs bedrooms but the price I was quoted online exceeds that of some of the best quality replacement windows (which to me would make more sense and add to the value of home in comparison to slapping inserts in front of the 23 year windows we have already).     Any advice or information you can give us is much appreciated.

Best thing to do is use our magnaseal DIY kit with 3/8" acrylic.. you need to achieve at least a 2" dead air space or greater between the 2 panes.
Make sure your current window seals are in good shape.
This system is far cheaper and works!
