Hmmm... maybe I won’t continue w the caulking around the drywall in the joist bays. Some of the gaps are about 3/4” though. My dad was using backer rod in cracks then caulking on top.
I’m wondering it would be helpful to install blocking within the joist bays between the theater and the adjoining guest room? The wall between is load bearing and the joists overlap on the wall - meaning the joist bays extend the width of the house.
On another note, our HVAC guy came by today and we discussed a plan for the theater. Given its location in the basement, he felt that I should be fine with the following:
A low cfm exhaust fan located in the ceiling above the media cabinet that vents to the exterior
An adjustable iris passive air port that will allow fresh air into the theater (pulled in by the exhaust fan).
This plan will vent my media closet as well as pull fresh air into the room. Win win. We talked about a mini split, but I don’t think it will be necessary (don’t need the cooling in the basement).
