Plenty of "VAC", notta lotta "H" - I'm about 320 miles north of Weed, been thru it quite a few times tho - Fireplace is great, it's semi-airtight, when closed down a notch above "compost mode", you can sit on it (bunwarmer mode) without leaving skin behind ( or is that, "behind skin behind"...)

Michael - "Nice looking camper/trailer there in the photo, Steve.
But with those incredible surroundings, couldn't you just pitch a tent in the back yard!?" -

The trailer is a temp, it'll move as soon as my 84-year old mom doesn't need it any more - tried tents, but on this hill plywood and 2x4's is temporary construction (had at least 80 mph winds here, some years not quite so bad) - best thing going is the view, house is marginal (gonna add on a 2-story with even better view due to higher vantage point this year, then build my "real" studio in 2-3 more, looking at 40 x 60 x 16 foot eaves with shell being 8" ICF concrete. Got a place off the bedroom end of the house where it will fit and not screw up any scenery)

Looks like the ice is pulling a "wicked witch of the west" scene, supposedly the cold snap's gone for a while (but you know how those weather people lie)

Later... steve

Here's a shot off my front porch about an hour ago - guess even "naked" beauty bushes can be pretty...

Wow - beautiful view Steve

I'm sitting here with just a sarong cos it's 90 degrees The weather's weird here too mate. Inland NSW which is normally 90+ is 60 today! - severe storms just went through south of me - could be a cyclone year - we are due for one.

cheers

Aren't you supposed to be on a pole somewhere fixing phone lines?

I think we all can say we miss your web site

room in a room

"I need you to run that one by me a little slower, with punctuation where it needs to be, and step by step like
you were telling a carpenter how you want it built - I'm not sure you aren't headed for another "acoustic no-no", til I fully understand what you're going to put where, and how many..."

The CR, Live room and Vox booth, ceilings frame structure shall be 2"x4" 16" On Center, a steel stud construction, suspended 2" below the existing garage ceiling but not tied to it in anyway. Their will be NO drywall on top of this structure, just riged fiberglass insulation between the studs. Attached to the underneath of these studs will be resilient channels at 90 degrees to the studs. The resilent channels will be 24" On center. Attached and suppended from the channels will be 5/8" drywall which will be sealed, then over the 5/8" drywall will be 1/2" drywall which shall also be sealed. this shall be the finished
ceiling of the studio, control room and vox booth. Only awaiting acoustic treatment if nesessary.

My studio design is on johns site

awaiting a few tweaks but I am using this site for construction techniques.

Thanks Steve

running into a brick wall

I spoke with a contractor very experianced with studios and large commerical construstion and he stated concerns about my inner room ceiling plans as stated in a previous post. His concerns are of having such large spans of drywall 2 layers thick suspended from resilient channelabove your head would not only be
dangerus but would require larger than 2x6 truss to suspend that much drywall without saging. I asked about 2x4 12" on center and you can guess his reply.
He also said getting a permit for that part of the construction would be impossible. Putting larger than 2x4 would not give me much headroom.

He suggested building walls up to existing ceiling and suspending a wirehung drop ceiling.

Steve my head is spinning
Please what would you do here
Thanks
Warren

Hello Warren, Steve, John< Michael...and everyone else here. Don't mean to interject my thoughts where they don't belong, but I had an idea. Warren, were you going to use metal stud for ceiling span? If so, its not designed for that type of application, because of the nature of light weight gauge metal. However, I've seen a type of construction whereby they hung UNISTRUT, by wires from existing truss's, with the wires tied to kinetic isolators. This was done whereby the isolators and wire were above the bottom chord of the truss's. The isolators were inbetween two wires, where by the top wires were fastened to added crossbraces between trusses, then tied to the isolators, then a lower wire fastened between the isolators and UNISTRUT, holding the Unistrut up within one inch of the bottom chord of the truss. Then hat channel was wired at 90 degrees to the unistrut at 12" oc . The sheetrock is then fastened to the hat channel and the whole ceiling becomes a floating ceiling via the isolators. Makes for a very thin ceiling structure, however, it must be approved via engineering documents and code. I've seen it done in Macys and a few other buildings in California. But I'm no expert, and some may disagree, but it is an idea. Expensive though. But as usual, solutions for problems such as homestudio room within a room ceilings usually are. I can't tell you how many times I've read about this very problem with other peoples projects. Its the nature of dealing with existing buildings not pre designed for this type of application. Then you have to deal with BID after the fact. Sorry for interjecting my thoughts in here, but thought they might be of some help.

Thanks Fitz
his suggestion is simular, but concerned me
about flanking , I guess I would have to see a
study or drawing to get it clear in my head.
Do you have a url that points to some examples?
Oh and thanks for your thoughts
it does help to have new ideas
I would like to get started soon

Warren,

I've never seen this done with unistrut....... but it is a typical detail using black iron - the hat sections are then tied to the blac iron using rolls of tie-wire...... and it does work but is expensive....... VERY. However - it adds some considerably heavy point loads to the structure.

RC added to the bottom of the trusses and then 2 layers of 5/8" should be fine.

The bottom chords of a trusss are typically designed for a 10psf dead load..... so as long as you don't have equipment loading up that bottom chord you should be fine. You will still need an engineer to certify that the trusses are capable of the load - but you are much less than a 10psf dead load with RC and 2 layers of 5/8".

But I don't understand the real issue......... you have trusses - why can't you frame with members in between the trusses and let the bottom be below the truss bottoms by an inch or so and the tops above the top of the truss bottoms?

What is forcing you to use 2x4 members?


What am i missing here?

He wants 2X4 because 2X6 would decrease his headroom.


But, a properly treated low ceiling is a good alternative to having a ceiling collapse.

If the ceiling that exists is drywall, you could nest 703 in between the existing ceiling supports to reduce the square footage of reflective surface.

Design submitted with a few questions

My Design has been submitted to the county for approval.
Many thanks for all your help!
I was also wondering about hanging bass absorption panels in the areas outside the inner rooms, where there is, on the far ends a 2' X 8' X 20'6" space, at the ends of unused hallway area 3'X 8' x 10' space, and also in the attic above.

Would hanging these panels be a help, hassle or hindrance? I had read in a past post about the formulas of the calculators used to determine the proper size of panel to the frequency to be reduced where wrong on some sites.
Does anyone know the write one to use?

Warren
