Debating on whether this is something I can do or if I need to call in an pro. I have a basement room I'm looking to use as a theater room, and I need to finish a wall to the ceiling so I can hang a projector screen. The top part in the picture is exterior wall, and the lower wall is 2x4 framing up to the top of the rim joist. There's a vapor barrier on the interior side of the lower wall, and the framing is right up against the concrete, no foam board in between. Standard fiberglass insulation in both.

My first thought was to just build a frame to finish off the top half, add some additional insulation, and hang some 5/8 drywall, but I assume I'd need to fill the air space behind this, and I'm not sure if I'd need to remove the drywall on the upper wall prior to doing so, or if replacing the lower wall and framing it to the ceiling would be considered the best practice in this situation. I've hung drywall and done some framing before, but not in a basement, and I'm concerned about creating some moisture issues.

Update: this is for a large 92" projector screen, so I need a flat surface to mount it.

  • Why make your life so complicated. Cannot you just simply hang the TV on the upper part of the wall and leave the lower shelf wall as is? – Michael Karas Sep 3 '15 at 12:58
  • I'm looking at hanging a large projector screen, not a TV. There's not enough room for this on the upper wall alone - it's a 92" diagonal screen. – justinb138 Sep 3 '15 at 14:13
  • It would still be simpler then to build out the mount points for the projector screen where they are inline with the upper wall. – Michael Karas Sep 3 '15 at 15:19

    Good point. I may look at that after I clean up some of the trim. Thanks! – justinb138 Sep 3 '15 at 15:20
