I just build a new house this summer of 2003. I put R-19 insulation in the I call the rim joice ( the area where the floor joice attached to the outside wall). Everything been fine until our Minnesota winters got into full swing..I noticed that the insulation was stuck to the joice because of frost in spots and others there was moisture and mold delveloping..

We do have and HRV unit for air circulation and run a dehumidfier even..

I never heard of putting vapor barrier in this area but that is the only thing I can think of..

Please give me some input.
