QUESTION: will Owens Corning R-11 EcoTouch PINK Unfaced Fiberglass Sound Attenuation Insulation Batt help significantly with the sound transmission?
I live in town homes, so they are 2 story units side by side. Upstairs are the bedrooms while downstairs are the living room, dining room, kitchen and a 1/2 bath. My neighbor has decided to place his bed in his living room and sleeps in complete silence throughout the day and night. That means my living room is next to his living room/bedroom. I have an exercise machine (Bowflex M5). I workout 30 - 45 minutes a day on it. When I work out there is a faint sound that makes it through to his unit. The sound is half as loud as if you where to lightly touching your hands together and rubbing them lightly.
The walls between units have a 1/2 dead space in between. They consist of studs, plywood, R25 insulation and 2 layers of drywall.
The 1st floor is raised 27 inches on pillions.
So far I have placed 2 sets of 4 Camco Olympian Aluminum Stack Jacks. Which completely canceled out any of the impact sound that used to accompany the swooshing sound and they reduced the over all sound that was transmitted by 70%.
Someone said that the Owens Corning R-11 Sound Batt would really help with the sound transmission, but I always like to get advice from more than one source. This is especially true because I don't want to throw away $600 if it isn't going to work. On a raised 1st floor will this product help significantly reduce sound to the neighbor 1st floor area if I place it between the floor joists?
Thank you for your time and I look forward to your answers!
