Best place to buy or brand of Drywall Furring Channel

[LegGodt]

Another question ...

Has anyone used the RSIC security straps that PAC International manufactures? It's only an additional $45 to my order, but I wanted to know if anyone else used them and their experience. My concern is that the drywall will not sit flush where the straps are located.

Any local supply house for drywall will carry the furring channels.

As to your 2nd question - I see no reason to bother with the security clips......

Is it worth using RSIC on the ceiling and Resilient Channel on the walls? The reason I ask is I already have the RC to do the entire room, but I am now considering RSIC for the ceiling because of the increased performance.

I do remember reading that a room is only as good as it's weakest link.

That being said, will the increased performance of the RSIC on the ceiling be noticeable since I will be using Resilient Channel on the walls?

The main reason for the RC on the walls is 2-fold
1. I already have it (Clark Dietrich RC Deluxe)
2. Budget ... can not afford the RSIC to do all 4 walls.

Thanks!

This is a very hard question to answer - this because there are a whole lot of variables that come into play....

There have been cases where I have done this - however I always designed for that to be the case when I did........

Fair enough ... maybe a little more explanation will help.

All the walls will be 2x4 normal construction with RC Deluxe and 2 layers of 5/8" Type-X drywall with Green Glue between the sheets. Three of the walls were already constructed when I bought the house. I have since added the fourth wall to enclose the room and removed all the drywall off the original walls and ceiling (the wife cried ... a lot!).

All outlet and switch boxes will be covered with Fire Putty Pads and I will be using Backer Rod and Acoustic Caulk to seals all the proper seems.

My room will be in the corner of the basement. The rooms dimensions are roughly 9.5ft x 15ft with 2 of the walls being along the foundation, small gap, then 2x4 wall, 1 wall is 2x4 construction with a utility room on the other side, and the final wall (the one I built) is 2x4 construction with the soon to be family room on the other side.

The family room wall will be RC on both sides with double layer of drywall and green glue on both sides.

I am not too worried about noise getting into the utility room.

Thanks!

Are the products that Lowe's and Home Depot good enough or should I go to a local drywall supplier?

Here is the drywall furring channel I am currently looking to purchase.

Just wanted to confirm that this channel from Home Depot is acceptable. I'm looking for an affordable clip for the ceiling of my iso booth. I read about "Z clips" but had a difficult time finding them. Who is a good manufacturer or store? The ceiling will consist of 2 sheets of 5/8" drywall with Green Glue between. Also, should I leave a small gap between the ceiling and walls and fill with caulk (to decouple)? What size gap would you suggest. Any help would be greatly appreciated!

As long as it is sized to fit within the clips it is being used for - it would be acceptable........

After I read this I found myself curious as to why you would think that "Z
clips" would be anything you would want to use for isolation - because this is not what they are made for - then I ran across another one of those idiots on E-how that is explaining how to use z-channel - which he claims is a resilient channel - yet another one of their so called "experts" who doesn't have a clue, for example he's installing the channels upside down (even if they were resilient - they are going to sag under the load of the drywall) - and refers to the studs in a wall as joists.

I had to have this site remove one of the BS "articles" posted by one of their contributors a short while ago because they didn't have a clue - and were using my name to prove their incorrect points.... personally I blame E-how for not having any real experts to vet check the people who claim to be experts.

Anyway - Z-clips and Z-channels are not isolation products - and if they are what you are thinking of using - then you may as well save your money.

Also, should I leave a small gap between the ceiling and walls and fill with caulk (to decouple)? What size gap would you suggest. Any help would be greatly appreciated!

In order for these systems to work - not only do you have to leave a gap between the walls and ceiling - but also between the walls/walls at the corners where they meet - and between the walls/floor.

All of the individual panels need to be able to "float" freely in order to maintain isolation levels.

I generally specify a 3/8" gap at the outside edges of each panel (by the term "panel" I refer to the entire face of a wall or ceiling - not the individual panels of drywall)- which are them sealed with backer rod and caulk prior to the installation of an adjacent panel. You should do a one coat tape job on the individual seams in the body of the wall prior to installation of an additional layer of drywall - and make certain to lap the seams of the additional layers as well.

So in a simple rectangular room the sequence would be -

1) Install 1st layer of drywall ceiling......... provide backer rod and caulk at all 4 edges.

2) Install wall panel 1 - seal as above.

3) Install wall panel 2 - seal as above.

4) Install wall panel 3 - seal as above.

5) Install wall panel 4 - seal as above.

For each additional layer - repeat the sequence above.

Great advice. I picked up a whole bunch from HD or Lowes, can't remember which, and some of them were ever so slightly smaller than spec'd. So that the clips fit too loosely. All the channels were just bunched together in the same area of the store, and described as identical on the website inventory. Probably not a bad idea to take along a clip and try it out . .

Excellent Rod, thank you so much! I was considering using the sealant that Green Glue offers, any opinions on this stuff? NOISEPROOFING SEALANT | Green Glue

I'm still trying to decide on some inexpensive clips for the ceiling of my isolation room (2 sheets of drywall with green glue between). There is no floor above the room to worry about, I'm just decoupling the ceiling from the walls. Any suggestion on what type to use and a good place to buy? Thanks again so much!

Any suggestions? My joists will be sitting on the new walls I've built in my room inside a room. The framing is complete but I need to make a decision about what I should attach the ceiling's drywall to. Could someone please explain what options are available with hat channel, RC channel, clips, etc.? Your help is extremely appreciated!

[mpowell]

Anyone?

My search for answers continues. Since I'm not getting much advice, perhaps I can post what I've figured out to help others. Metal furring strips include both resilient channel and hat channel. However, hat channel actually attaches to clips for superior low end transmission loss. The rule of thumb is one clip every five square feet. I suppose I'll randomly throw my money at some online retailer and hope that the clips work out. I'm thinking whisper clips. I'm guessing that this will work with those clips:

If your ceiling joist are sitting on top of your new walls - and thus isolated form the space above - why do you think you should have clips and channel?

Not needed - nor preferred - just add your mass directly to the underside of the joist........ after insulating the cavity of course.
