Great looking room shazapple(s)! The ceiling is really a nice touch. And I know how much you'll appreciate that insulation now that winter's here.
To downtowndahlgren: we had/have the ugly 12 x 12 acoustical tile in the entire downstairs of our old house, which we figure was installed in the "unsympathetic '70's (emphasis on "pathetic"
). When we did our living room about 12 years ago you couldn't find this type of tile. We weren't in a position to pull the whole works down to do it "right" so we opted to cover over the acoustical tiles which were in good shape - just ugly.
We covered the ceiling with a layer of "liner paper" which is a fairly heavy porous backer. Then we papered over that with an embossed vinyl wallpaper that had a pattern reminiscent of the tin ceiling look. Other than one spot that wrinkles slightly during really humid weather, it's held up amazingly well. (pics below)
If we were doing that room now, we'd definitely be looking into the styrofoam tiles like shazapple used. On the plus side we can use them when we get around to redecorating the dining room.
Looking forward to the kitchen reno...
