- dual purpose quiet space for (co)working and audio/video recording
- friendly, open, clean, comfortable
- sound dampened
- sound proofed
- good lighting
- colourful lighting
Phase 1 Goals: Comfy Start
- floor installed
- storage (shelves?) up
- first sound dampening panels
- target date: June 19, 2020
Phase 2 Goals: Shhhh
- sound proofing, eg drop ceiling, partition wall…
- trello board - public, need to be a (trello) team member to edit; just ask
- layout ideas (tinkercad). Note- sound studios often have panels at 45˚ in corners to break sharp reflections.
- eventually might want ~25 2’x4’ sound panels (both for some sound proofing but also dampening.)
Plan of Action
- insulate wall shared with Otagai - blow in cellulose and/or 2nd layer of drywall
- for office/work use, want to make it comfy; room-in-a-room would leave outside space still potentially noisy. And it keeps more flex space for now
- less labour to do some insulation now rather than later- can always add more if needed
- waiting on QuietRock quote from Slegg, probably too expensive, Green Glue + 5/8 Type X?
- paint walls and ceiling (have primer + white paint on hand)
- barrier: https://www.homedepot.ca/product/dmx-plastics-limited-dmx-1-step-2-0/1001513953
- 5/8" OSB T&G on top (don’t trust rigidity of floating laminate)
- NOT screwed down to concrete- leave floating
- may require 2nd layer @ 45˚ to keep T&G locked in place; possibly 1/2" plywood, may almost have enough on hand
- felt underlay (on hand)
- laminate wood (on hand)

- (Roxul vs Fibreglass vs Cellulose)[https://bettersoundproofing.com/best-soundproofing-insulation/]
- absorption coefficients
- Acoustic treatment and design for recording studios
- room size is ~10’x16’ with cutouts needed for plumbing stack, and door
- floating subfloor over concrete

- looks like stack-up is: water seal, insulation/padding, hardwood floor - taking care to allow for expansion gaps and that sub floor grains are counter to laminate direction
- cheapest: https://www.homedepot.ca/product/roberts-10-x-12-feet-x-6mil-moisture-barricade-underlayment-sheeting-for-laminate-floors-120-sq-feet-roll/1000473570 - may require FOAM underlay (have felt) - ~$50
https://www.homedepot.ca/product/dmx-plastics-limited-dmx-1-step-2-0/1001513953; ~$160, low/no R value?
- some googling suggests R value is ~0.91
- would want OSB over top, possibly also cork (~$1/sq ft.)
- 4x8 T&G OSB is ~$20 sheet, need 5?
- sound iic ~69?
- https://www.homehardware.ca/en/235-x-235-air-plus-subfloor-panel/p/2818016?page=search-results%20page; ~$260, R1.4

- https://www.homehardware.ca/en/4-pack-155-x-48-x-1-254-mm-thermosmart-subfloor-panel/p/2818014?page=search-results%20page - seems more expensive for lower R (3.0)

Materials On Hand
- some lumber
- several lengths of heavy curtain/other cloth
- maybe dye it to look nicer? Or a second material to cover it? Most of it is heavy upholstery fabric.
- left over white paint (almost enough to do corridor; should be more than enough for room), blue/green and some other colours
- left over drywall sealer
- laminate hardwood floor planks
- maybe enough (felt) underlay
- vapor barrier (if needed)
- green, blue, and projector screens
- Tile smart panel
- Home Depot has “Green Glue” noise proofing sealant
- There’s a commercial supplier of membranes, sealants, etc, behind WSBC Courtenay
- Industrial Plastics and Paints may be able to get some of sound sealing products
- QuietRock- see below re agent in Campbell river that also had the springy/noise-absorbing dry-wall installation clips.
- acoustic panel example Thomas Sanladerer; at end brief comment re heavy rock wool vs regular.
- previous investigation: contacted Kevin Boily @ Westcoast Home Theaters who put Julian in contact with James Wright @ Primacoustic in Port Coquitlam.
- James suggested:
the acoustic treatment in the space is the easy part. I would suggest a London 16 room kit and 2 Stratus Clouds.
The more difficult issue is the isolation from above.
First step I would look into is framing a sub ceiling (2x6) and filling space with Roxul Safe n Sound Mineral wool insulation (home depot) Then I would use Quietrock drywall (sound isolating of 7 layers of drywall available special order at HD) I would the caulk all the seams using Greenglue acoustical caulking.
Hardwood will help I would also suggest an area rug if possible. (Real hardwood has a much warmer resonance than laminate).
There are easy ways to apply the panel hardware to both cinder block and drywall.
- this lead to a room-in-a-room concept:
- vapour barrier on floor
- build inner room around 8x12 with regular ceiling height, using recommended drywall
- rock wool insulation between inner and real walls and on ceiling.
- inside room put down plywood subfloor with a gap from the walls to reduce vibration from floor to walls
- laminate on ply
- rugs on laminate
- hang acoustic panels you recommended
- James’s feedback on this: “he room in a room concept works great if you have the space and the skills. Your process sounds good. A sub floor is always a good idea under laminate over concrete.”
- QuietRock is equivalent to 7 layers of regular drywall in terms of sound dampening
- there is/was a QuietRock supplier in Campbell River that Kevin recommended. They also had the appropriate metal mounting brackets and anti-vibration fasteners for drywall-on-drywall installation. Via QuietRock.com Slegg in Cumberland is a dealer.
- Julian was highly recommended Autex Vertiface (NZ made, polyester based, very fire resistant, very durable) and Autex suggested Cube would be a better choice
- US/Canada rep is Jeremy Winter. Was willing to try and help re cost- eg left over from an order/cancelled order stock in LA at reduced cost. BUT had to sell whole lot/no choice of colours…Probably not realistic, but if someone is building a high-end home theatre, perhaps we could co-order a couple of sheets.
