Wooden walls acoustic insulation (truck traffic)
« on: May 26, 2015, 10:10:53 AM »
Dear all,

I have purchased an old house in central New Jersey (1959) with external wooden walls (schingels outside). The house faces a noisy road with truck traffic. I plan to change all windows of the house with laminated double pane windows (STC = 36). However I don't have enough budget to have someone insulate all walls so will just start with two bedrooms facing the noisy road.

I have the following questions:

- My bedroom is on the second floor below the attic. Should I also insulate the attic ?
- what about the floor of the bedroom ? Should it be soundproofed as truck noise may come from downstairs ?
- I don't want to tear down existing walls. Is it a good idea to "add up" another internal wall with Roxul AFB in between existing wall and new wall ?

Does anyone know about a contractor specialized in soundproofing in Central New Jersey  ?

Thanks in advance for your help.

The problem here will be that any work done to the walls might not be noticeable because the window could still be the weakest point in the system.

I would say have the windows installed and assess the results.. if you no longer focus at the window when you hear noise the we can start to address wall treatments.

Remember that sound will always go to the area of least resistance therefore you build the bubble equally.
