If you were going to use sheets of material, using GreenGlue soundproofing compound, what would you use? OBS, plywood, drywall?
Weight would be a consideration, but each door will be 24" or slightly less.
I plan a double door about 48", with the edges of whatever I decide to use, staggered slightly so one door closes over the other a bit.
AND, I am open to any and all suggestions regarding both the doors and the door frame.
I think I am going to build a separate 3rd inner wall using 2x3s or 2x2s, leaving a small gap between the 2 sills, although I did put down a 2x6 sill for staggered studs.
OSB and drywall are cheap and I think 2 sheets screwed together with GreenGlue would be a cost effective way to go.
I'll add the 3rd wall providing that leaves the required floorspace for my CV1800.
I just could not pull it all together this past summer. Too much rain, too many accidents/injuries, and too much pain. Doors are something I can build indoors, after the sheets are sawn.
