Time for the usual minor update. My first order of business was to take down the last layer of 5/8" DW from the sides of my joist cavity. It's not needed with the changes to my ventilation strategy. I left the 1/2" since it's not really hurting anything. I suppose I could have left the 5/8" as well, but I feel better with it out.
With that out of the way, I started adding R19 to the ceiling. I also had to add some blocking at one end where my joists change direction. Here you can see a little of both. I'm sure the old timers around here have already noticed the problem with my sound proofing strategy. My insulation is not pink............ My head is hung in shame
With that out of the way, it was time to start adding the furring strips to my ceiling to lower everything below the 18" beam that bisects my room. Here's the load of 1-1/2" furring strips (commonly referred to as 2x4's) ready to be hauled to theater. I bought ~80 8' 2x's, but I think I'm going to come up a little short.
Here's their temporary home before going on the ceiling. I suspect I'll be doing the building material shuffle a lot before this is all done
And finally, I managed to get started on adding the 2x's to the ceiling, but I ddin't finish. It's going slower than I expected. You can see the beam that's causing all the trouble. With the 2x's + clips + channel, my first layer of DW will be 5/8" below that beam.
To put these up, I've been marking the ends at the front and back of the theater, and using a self leveling laser level to project a line from one end to the other. Seems to work very well.
I will say I wish I had a framing gun
! I've been using 2-1/2" deck screws, and while they hold really well, it's been tough on the 'ol Ridgid cordless. It will drive them fine, but the battery life suffers! I've got an impact driver as well that came with the set, but it's a good bit slower than the drill. Working over head, I'm all about getting it done quickly. At any rate, with a framing gun, I'd probably be finished already.
I'm sure you'll notice the empty joist bays. The spacing is not uniform, so I've got a few that the batts will not say in without something to hold them. So I'll add the insulation once I get the furring strips up.
On a side note, I had to look quite a bit to find 25 ga. hat channel. Here's a pick to prove that I did (BTW, it's nice to have a 4 wheel drive)
I ended up finding the only local drywall supply house in the area. They had to order it as it's becoming less and less common to use the stuff (apparently). I'm told everyone is going to 22 ga. The bright side is they have the stuff at about 1/2 the cost of Home Depot. They also sell DW and insulation much cheaper than Home Depot or Lowes. In fact, the cost of 5/8" DW delivered into my theater
is less than HD and Lowes list their 5/8" DW for.Edited by J_P_A - 11/28/12 at 11:04am
