Highway noise behind house
« on: May 18, 2006, 10:26:32 PM »
Same old story - new house facing open bay - beautiful view from front porch.  Back yard is against 6 lane highway heading to seaside resort.  Presently have 6 ft stockade fence.  Previous owner situated swimming pool near house and patio against fence.  (Duh!) We are having a hard time sitting on patio.  This is a crazy idea, but maybe......Why not take rigid insulation and run sideways on inside of fence between horizontal supports and then place another layer of fencing facing out.  I have read all about the "taller the better" but for right now there is a 6ft fence and if you are sitting wouldn't it help some?  Better than nothing?   :-/

Rigid thermal insulation doesn't do a good job blocking noise.  It is sometimes used to reduce resonance within wall cavities but the material is too light (around 2lb./cu. ft.) to resist noise transmission.

A better material would be 1/2" exterior plywood. If you go this route, it's a good idea to reduce the gap between the fence and the ground as much as possible.

Noise will still flank over the top of the fence and a lot depends upon the line of sight from the traffic to your home. However, if you are sitting close to the fence you should notice some difference.

There are many people with your same problem. Highway and traffic noises are becoming more and more of a problem with home owners. The real solution is to encapsulate the sound at its source or where you do not want it to go. We are not going to encapsulate our highways or our backyards. A taller or thicker fence is not the solution. Sound will go up over any fence and go on into the neighborhood.
