anonymous, you love these threads!
I would agree with your first question, though. However, the answer is don't look to Ballast for the answer. Use Fundamentals of Building Design or Building Construction Illustrated to find out spacing for masonry anchors.
Split ring connectors are a destructive connection and cannot be disassembled and then reassembled. Shear plate connectors preserve the strength of the connection, if the assembly has to be taken down and put back up.
The gyp board question is stupid. Agreed.
NRC is a unit of absorption, STC is a unit of reflection. NRC reduces echo in a room, but not transmission from one room to another. STC does the opposite.
The BUR question is silly, but the concepts that they're explaining aren't.
The EPDM question is a little silly, but EPDM is
not a thermoplastic. The Virginia part and the rest are pretty silly. Gaps in pavers won't let roofing heat up enough to deform, but using only paths of pavers means a lot of exposed roofing.
Most firestopping I've dealt with has been gypsum or mineral wool. I suspect that FRT wood would be okay, but I'm really not sure. However, the treated wood seems like the only answer that could possibly be wrong, in this case.
