Insulation wrong

Posted by Colorado Dave on February 4th, 2003 02:36 PM

I just moved into a house that has a 4' crawlspace, with concrete block foundation walls. The floor insulation is R-19 fiberglas batts installed upside down, that is the vapor barrier (kraft paper)is up toward the floor. The perimeter vents were closed off and there was a slight amount of water in a depression (2" deep for about a 1 1/2'radius). The kraft paper in areas seems to be a darker color than it normally is, but the joists are normal. I opened up all the vents, installed an automatic sump pump, and am now considering what to do with the insulation. 1) Is it worth removing and reinstalling the insulation right side up? 2) Are vapor barriers really necessary in an area with low humidity? 3) There has been no return of the water since I installed gutters and extended downspouts away from the house. Thanks in advance for any help. Oh yea, in an attic space next to cathedral ceilings the insulation on the vertical walls is also backwards(kraft paper toward the cold side).
