I am looking for information on penetrating a sound wall with dielectric fittings or a waveguide or something of that sort. I have sprinkler piping passing through a sound wall for a government job, lots of spec's very little direction, and they want something that will minimize the sound transfer from one room to the other. Can someone point me in the right direction. Any help would be appreciated. Thanks, Jason _______________________________________________ Sprinklerforum mailing list Sprinklerforum@firesprinkler.org http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum
