I spent a large part of last weekend stripping wallpaper and removing crown molding and chair rail from my dining room. I was surprised to find that the top of the drywall is about an inch and a half short of meeting the ceiling in that room. From a redecorating perspective, it's not that big a deal since we'll be installing pressed tin ceilings with a cornice, so the gap will be covered again, but I've never seen this before.
The ceiling gives a little when I push up on the edges, but seems sturdy in the middle; the whole ceiling doesn't push up.
Is this common? Is it a sign of poor construction? Is it something I should rectify? Does anyone know if there's any kind of insulation value lost from having it this way?
TIA for any opinions/information!
