Since I am just about to embark on this part of my build, I figured I might as well ask (even if it is a dumb question)---is this the proper construction sequence?
1) roll out 1" linacoustic, screw to drywall
2) roll out 6mil plastic, screw through linacoustic to drywall
3) roll out 1" linacoustic, screw through plastic and first layer of linacoustic to drywall
That seems the most natural to me, though I wasn't sure whether some people instead make the sandwich first, then mount the entire thing up to the wall all at once with a single layer of screws. Seems like that would be nearly impossible to do with just one person, however.
