Multi-purpose Music/Home Theater/Recording Studio

Yes, « the bolt and washer attached to the top plate also the bolt that runs through the pad and into the slats » but before inserting the bolt we inserted a piece of rubber hose up to the top of the slat, so the bolt and the washer do not touch the wood (the washer crushes the piece of hose that protrudes on the slat and on the bottom of the top plate) as we did to fix the walls on the exterior wall.

Does this change your recommendation?

in looking closer - you have a bolt with a washer contacting the lower plate, the bolt threads are wrapped with hose, a pad between the plate and ceiling slats, a hose through the opening in the slat, then a washer and nut on the bolt. the members are still coupled because the bolt transfers from the plate to the slat at the washer connecting point - what you want is a decoupling of the washer as well. see Kinetics Noise KSR 25 assembly for the concept.

on sealing the wall-ceiling gap - typically your sheathing on the walls and ceiling are staggered to around 1/4" separation on each layer and those are sealed. the depth of (typcially) 1/2" plywood/osb + 2x 5/8" type-x drywall would give you 1-3/4" thick "edges".

Hi,

The work is progressing well. The gym is almost finished, and we're about to begin work on the studio. Here's what's been done since my last update in this (construction) thread.

• Plastering and paint
• Installation of PVC door and window moldings
• Necessary improvement of the radiant heating system (unforeseen cost of $1500)
• Installation of the sliding (retractable) toilet door

• closing the top of the wall with a layer of 5/8 OSB and 3 layers of 5/8 gypsum so that the last layer touches the ceiling (well sealed after each layer)

• installation of the ERV and preheat coil above the toilet
• installation of soffit exhaust vent to exaust stale aire and soffit intake vent for the supply of fresh air from outdoors (done by my HVAC contractor).

• installation of ventilation ducts (gym only)
• holes in the drywall to run the conduit into the studio and another for a 3-inch pipe to run the electrical wires through. Conduits and pipe are sealed from each side.
  
  1. preheat coil
  2. fresh air to the studio (flexible acoustical duct before enter the wall)
  3. fresh air to the gym
  4. stale air from the studio and gym (the hole is on the other side of the gym)

• I sealed the wall corners and the top as best I could. Fiberglass in the top and fiberglass/backer rods (red arrows)/gwb 5/8/sealant in the corners.

• We built the frame to hide the HVAC and electrical installations. We can close it when we're done running wires to the studio.

• I applied 2 coats of sealer to the floor (to protect and facilitate cleaning)

• Construction, painting and installation of baseboards, moldings and speaker shelves.
• Installation of suspended ceiling (by a contractor)
• Installation of the fresh air and exhaust air diffusers (before each diffuser, the duct terminates in 3 feet of 6-inch flexible acoustic duct)
• Installation of the 2 light fixtures, TV and Stereo wall mounts (I used surface PVC electrical outlets and sealed the hole in the outlet and on the other side of the wall)

• I bought a router and a friend of mine came to make the connectors in the house and the gym. Wifi up and running!
• Cleaning the studio and moving things from the studio to the gym. Studio (and more interesting) part ready to start ! (but first I will continue soon on the Design Forum)

There you go. I know it's not perfect, but we're doing our best.
Feel free to comment, whether positive or negative. Thank you.
