In the off topic of the carpet thread that went into a tangen, I did some thinking and planning and realized that a drop ceiling would be more expensive than drywall one. So have to do some leveling of the exisiting joist which should be easy and only counted 3 hand holes that will have to go in for shut off valves. Now time to insulate!:T

You can build a hatch for the ceiling access. PM me if you want a diagram.

Thanks, right now in the middle of insulating and it is warm out so just sweating my but off.

You also must have access to all electrical junction boxes (they can not be covered by drywall).

I did count them and it is only 3 the other stuff I can move into the utility room.
When you guys say building walls decoupled from the foundation with those isolation brackets I built my walls a full 12" from the foundation. Now I finished insulating the ceiling WOW big diff without the drywall installed yet. I guess my next challeng is my HT spot does not have a door for its own room. It is sort of another living room in the basement that I am turning into a HT. I noticed that the sound goes right up the stairs like a funnel. Should I get a type of door that is sound proof?

You can try an exterior door with weatherstrip. Or two of them such that when closed, they create an airlock.

Decouple the drywall from the joists if possible

To late to decouple the walls from the joist's. Does it make that much of a difference if just left the way it is? I will be using the hat channel for the ceiling drywall and that will be connected to the joist also or?

 

[the colors]

I was referring to the ceiling drywall on the joists. Clip + channel would do it.

Walls are fine as-is

Sorry I am used to carpentry but not this kind so it's a bit new for me.
What is the web site that sells those clips?:huh:

 

[the colors]

Many places sell many clips. To directly answer your question, we do, though I don't want to come across as a commercial.

Sound away, I would rather buy from you guys since I did join your site.
What I do need is how they are installed in relation to the hat channel and joist's.
Also what is the price and in your opinion are they worth it in sound traveling both ways through the ceiling/floor.:whistling:

Well after doing some homework at that site I feel better about what I am doing. Luckily above the HT area I purchased a higher end carpet and padding and since insulating there is a difference.
Another question how do you join the edges of the drywall to the walls.The hat channel does not go all the way to the corners. Is that ok and I like those Whisper clips, thinking about it.

 

[the colors]

Ok got it!,Now I just need to figure how many clips needed. According to the specs I can space them every 24" down the hat channel and how about side to side spacing?

 

[the colors]

Looks like I need 36 Whisper clips. I have to say spread out over 4ft seems scary but I guess the deflection is what absorbs the noise. So much to learn and when you think you have it figuer out they change the rules.lol:bigsmile:

 

[the colors]

If using the proper channel you're good to go. Unless you exceed two sheets of 5/8". Then you have to change the pattern, with rows every 16" instead of 24"

I will be using 1/2 drywall and maybe Green Glue with a second sheet of 1/2. This would be Ok?

Well I did check out the Whisper clips for the Hat channel and most likely will be buying them.onder: I did a little tinkering and designed my own set sort of. What I did was cut strips of EPDM rubber 1.5" wide by 4" long @ .25" thick and will install under the Hat channel to the floor joist's. Also I made EPDM washers to isolate the screw head from the Hat channel and a steel washer. So essentially the Hat Channel will have the ability to move ever so slightly. I know this is not a tested method but what do you think? I know it will be secure so the sky won't be falling.lol

I may not described it to good but I am going to pre drill the Hat Channel to allow the flexability so as it is not being crushed to the joist's by the screw head. I most likely will buy the clips but I may do this method in the laundry room were there is hard wood floor above and it is not over the HT area. I will get some pics together my wife has them somewhere.

You are going to pre-drill slots on all the joist attachment points? 2 per joist? That's 304 slots to cut for a 15 x 24 room. You will also have 2x the contact points with these contact points being more conductive.

I see the logic now, THE CONTACT POINTS!. The clips use one and mine would be two. Yes I would be pre-drilling all the attachment points two per joist. See told ya I would be buying the clips Now need to do a better more accurate count and level out the joist's. Remember my house was built in 1913! nothing is level.:rofl2:

First of all, I admire your cleverness. It's logical to go down the road you have.

The whole system is made or broken based on on that Hat Channel. It's the weakest point in the drywall suspension. The thought of modifications to it scare me is all.

Point taken, when I build somthing I tend to over engineer things..glue it and screw it mentality.:bigsmile: I just looked at those clips and they also have two contact points(Whisper Clips).Which ones do you prefer for ceilings?

 

[the colors]

Thank you Sir for all of your help. Do you have sombody as a contact to order these clips from?

 

[the colors]

I have to say I see some threads were the Hat Channel seems to be to thin. I get what you guys say about wanting the ceiling to be isolated from the joist but the guage steel that I see being used scares me to think that 2 layers of drywall will just stay there.:sweat: I am using a heavier guage steel it may not be what recomended as far as flex goes but it gives me piece of mind.
Before I order my clips I need to run all my wires first and really think about placement of speakers.

 

[the colors]

When I get home from work I will see what guage the Hat Channel I have at home from a previous job I did. What I will do is measure it with a micrometer and post the thickness. Sorry for being a PITA but I just want to do it once and right.

 

[the colors]

I checked the thickness of the hat channel and it is 1/16" thick. Is this to thick?

 

[the colors]

See told ya, when I build somthing it's allways overkill. This is a totally a new way for me in building methods so I am just hesitant in the flexibilty thats all. But one way to put it is if air plane wings were rigid in design they would break off!:gulp: So I guess the flexibilty is a good thing eh. I will be ordering them soon and I have to make a trip to get the proper hat channel. Again thanks for all your input it really helps when someone else knows what they are talking about.

Well I am just about done painting and getting ready for the carpet. It has been a long 5 years in this whole basement project and need to post my pics of what it took to get to this point. I would call this room a Living room/ viewing room due to other rooms coming off of it. But I did set it up for MY veiwing pleasure.
