My house is 100 years old and we just switched out the single pane wood windows/aluminum storms with double hung vinyl replacement windows. One of the prime reasons we did the job was to save energy and cut down on street noise. So far we seem to be striking out on both.

I think my contractor did not properly insulate around the windows and that is why we have more noise/less heat in every room in the house as compared to the old windows/storms. The windows look great and open and close great, but we are miserable listening to a nearby highway we did not hear before the windows were installed.

Does anyone know what type of installation or how we should proceed to fix this??
