Lbear; Is there a reason you are going to great lengths to achieve soundproof?

I talked to sound proofing engineers and they all stated that SIP roof panels are notorious for poor sound isolation and that they actually amplify sounds. They recommended that I install 2x3 wood furring and then install the hat channel and clips onto that. This will give me almost 3" of air space, which is what they recommend for low frequencies and mid to high frequencies.

I need to furr out the ceiling and so I figured why not attain soundproofing to avoid the potential of that "SIP pop" issue. Being that the area sees 40 degree temperature swings in less than 12 hours, and the monolithic type of structure that a steel SIP is, I don't want to have any sound issues coming from the steel SIP roof/ceiling.

What is the load rating for a steel SIP on the underside? What is the 26 gauge steel pullout strength in regards to screws? Is it more or less than 3 LBS per sq.ft.?

Yes, 7/8" or 1-1/2" x 25 ga. steel hi-hat can hold ceiling fans, it will certainly hold ceiling weight

What do you think of this product?

Resilient Sound Isolation Clip

They claim it is 36 LBS per clip for design load. It uses only one screw but has a rubber isolator.



Or do you think this one would work better?

Soundproofing Company WhisperClip

This one uses TWO screws to hold the clip but does not include a rubber isolator.

........... a #10 x 1-1/4" pan head screw has a value of 166lbs per screw

What is the load rating & pull out strength for the 26 gauge steel SIP on the underside?  Coarse or fine screw?

LBear;
166 lbs. is the pull out in a 26 ga. skin, a 1-1/4" pan head would be a sharp point / coarse thread, DO NOT use self drill or fine thread

Question:

With a steel SIP ceiling, using steel hat channels to which 5/8" drywall is attached to. If installing a T&G ceiling onto that. How would one attach a T&G to a steel hat channel WITHOUT using screws? Typical install is a nail through the tongue edge at 45 degrees with a finish nail to hide the fasteners but that is with using a wood furring strip.

I guess one could counter sink the screw head and then cap it off or patch it off?

Lbear,
yes its installed with a pnuematic trim nail gun , which will penetrate 25 - 20 ga. steel
we use trim nailers to install all of our interior doors and trim to steel studs, the only time we use trim screws is into 18 ga. or heavier steel.
