Bethesda Build - Page 5

oh - one more thing about the clips - we've been using laser levels instead chalk lines - of course - you have to make sure the laser is level before you install the clips - but that's a different story

yes - screw both layers in - first layer we used 1.5" screws (maybe 1.25" don't really remember), for the second we tried 1 5/8" but it wasnt enough so we went with 2"

oh - we also staggered the seams on the drywall - my original plan was to sandwich the drywall first then screw both layers in at the same time - but we decided against it in order to stagger the seams appropriately (also much easier to lift up over your head)

Boy did we get a lot done.

here's the synoposis

• Installed all the clips on the ceiling
• installed hat channel throughout the entire room (except two lines under the bulkhead)
• figured out lighting and bought the cans (basically copying brad - 3 main zones, 1) 4 gimble stage lights, 2) 8 lights in soffit, 3) 3 rears or track in back under bulkhead) accent lights will be 4) soffit tray, 5) stage, and 6) riser
• ran the cat6 to the closet to run up to the front door for a security cam
• insulated the whole ceiling (including a very painful first joist which we stuffed with pink stuff and roxul)
• patched up insulation throughout the room - including the new closed off window
• caulked and insulated around the closed up window
• ran conduit - 2x2" for the A/V in the room and 1x2" conduit for the projector
• FINISHED THE WIRING! - yay- big might disagree, but basically we put wiring in place for all the lights so we don't have to run it through the soffit
• The Rack! - it's gonna be awesome - Mr. Big figured out a very very elegant solution to making the rack look just right in the back of the room
• Wired everything into the sub-panel - but my electrician friend refuses to power the panel until he checks our work

Ok - now pictures

Insulated Ceiling


Nasty front joist- had to stuff pinkstuff in and around a duct, and capped off the end with a bunch of roxul - i'm still itching from the unfaced pink stuff


Mr. Big doing some damage with a staple gun (actually just securing hte insulation in the joist)


two conduit lines from the equipment closet to where the soffit will eventually go. you can also see the rear bulkhead here which we stuffed about 3 layers of insulation in - this bulkhead also ended up using a lot more clips than anticipated - need 12 more clips to finish the channel


conduit lines from the equipment rack into the room


Conduit line to the projector location

Need to update with pics of the whole room channeled - looks amazing

Also need to add a pic of Mr. Big's beautiful work on the rack

A couple of things of note:
- underestimated clips and channel needed because of that rear bulkhead - basically need two more rows for that, as well as a little channel for the corner where the rack is.

Luckily Mr. Big found channel at his local Home Depot and John and Ted are super fast at shipping!

- looks like we're gonna be a little short on drywall - my previous post mentioned just how much supply we needed to dampen the floor above - we'll need about 12 more sheets b/c of all the waste cutting those - just gonna have the drywallers bring it with them
- finally - used up a lot more insulation than anticipated stuffing large cavities like the bulkhead

whew- this is getting expensive in terms of overages - oh well - it will be awesome and quiet when its done

so.... 2 more rows of channel when the clips come and then DRYWALL!

very happy with the progress so far, and once again, couldn't have done any of this without the help of the illustrious Mr. Big

Lol - he's standing on a stack of drywall - ceilings are about 8'

one other thing i forgot to mention. In order to install the channels we had to add extra 2x4 studs in the corners. This allowed us enough room to keep the channels from butting into each other or the perpendicular wall

Neb,

Im not really an expert here - I would definitely recommend you check out the Sound Proofing Company website http://www.soundproofingcompany.com/

There's lots of good data there, and installation instructions as well - here's the instruction page for the clips
http://www.soundproofingcompany.com/..._instructions/

Also - here's a good video that shows how to do it (not to sure about the 3" from the bottom though - we used 6")

Here's another video (different clips though)
http://www.youtube.com/watch?v=Bf5syq09qa0

Basically, my understanding is that the amount of clips depends on 1) how many layers of drywall, 2) whether or not you need to support a soffit

Also, you don't need to install clips on every stud or joist - you cover the two ends of the wall and then install the clips in an angled pattern but no more than 4 ft apart (it looks like diagonal lines when they are installed)

for 16" OC joists we installed them every three joists and then staggered each layer - so the first layer was 1) clip on corner, 2) then count 3 joists and install, 3) repeat until we hit the opposite corner and install a clip there

for the second layer it was 1) clip on corner 2) count 2 joists over, 3) count 3 joists over and 3) repeat every 3 until we hit the opposite corner and install a clip there

next layer we counted 1 joist over after the corner

layer after that - it was back to 3 joists after the corner

hope this helps - but really talk to the soundproofing guys - they're a huge help

See - Ted's the expert

we actually followed this advice and used deck screws to attach the clips to the studs - they also have the star bit pattern - so the drill could grab them and drive them home better

the stack actually helps - didntt need a ladder for the insulation or clip installation - installing the drywall itself might be a challenge - but we're contracting that out

Don't forget insulated (well at least 1/2 the walls and the ceiling)
