I live next to an Air Force base and have issues sleeping when I work nights and they are flying. I have a two story house and am looking to quiet down one of the upstairs rooms. It is a simple square room with one exterior wall with a sliding double paned window. My plan so far is as follows:
-Build a double stud wall on the exterior with a 1 inch gap with R-13 in both inner/outer frames. DD+GG drywall.
-Build a slide in window plug mimicking the inner walls construction. May eventually put in a inner soundproofing window.
-Do staggered studs 24" OC on the interior walls with R-13 and DD+GG. I don't want to use clips here for the hanging stuff up issue, and double stud would cost too much floor space.
I have questions regarding the ceiling and floors. I am willing to rip up the subfloor. There is an attic above the ceiling with easy access. The only two penetrations I will have are HVAC supply and return.
-Should I use clips and hat channel or install lowered joists on the ceiling or just go with DD+GG on the existing joists?
-Should I install sub flooring in the attic? If so, one layer or two with GG? Would this create a triple leaf with the roof above? The attic is well ventilated, so I am currently thinking it doesn't count as a space.
-What can/should I do to the floor?
Cost isn't really an issue here, I will just spread out the construction if I have to.
TIA for any advice.
