Replacement windows are noisier than our old windows...
I installed Pella Thermastar replacement windows in our house last summer, we were hoping the noise level from the highway ( about 1/2 a mile away as the crow flies ) would be greatly reduced. Sadly the highway noise is worse than it was with our old single pane + storm window setup. With the new replacement windows the highway noise has taken on a different quality, like you're listening to it in a tunnel is the only way I can think to describe it.
It's been a year since I installed these and have revisited the install a few times in between, adding more insulation to make sure there are no gaps, etc...nothing has seemed to change it.
Any ideas on this one? Maybe I should have bought better windows?
