Drywall installation with Hat Channel

[scottmartin]

Hello everyone.

I am getting ready to start installing drywall(double drywall) on my hat channel, and when doing some planning, I ran into some questions that I was hoping some more experienced people might be able to answer.

1. For my ceiling installation, I realized that some of the drywall edges will not align perfectly with the hat channel, thus hanging in between the hat channel and not secured. Is this a problem? If so, is there any solutions?

2. Is it recommended to install the second layer of my double drywall in the opposite direction, or can I just go install it in the same way, but try to stagger the seams?

Any suggestions on installing double drywall on top of the hat channel would be welcome.

Its so simple in concept, but i used it once and went back to timber! The thing to remember is that the building purpose is simply to keep the sheet attached. For the person doing layering, the trouble is finding the channel strip for layer number 2! If there is a gap, you have lost the structural support there. If that is not vital, it wouldn't worry me too much if i was adding a layer on top, if the loss of two layers at that point was a big section, then you have allowed a path out. I suppose that due to the wavelengths, it just makes bass performance at that point compromised a little, and these things add up. Can you not fill the gap with an offcut? It wont be structural, but the next layer sorts that? If the weight of the sheet is on the vertical supports and not the floor that puts more stress on the screws left holding it. Is the gap a long one or short? Post a pic if you like.

What i have always done is patch on one layer. Some filler on the patch and cover with the next sheet.

Murphy’s law always means on the next layer you always screw into thin air at some point.
