I have a log home in north georgia.I just noticed this weekend when cleaning out some lower cabinets that they had condensation moisture coming through the back of the cabinet at the botttom 6" off the floor. Its definatly not a leak from plumbing or roofing.We had a cold weekend, but none of the other outside wall cabinets showed this moisture, including under the kitchen sink.The cabinets are fastened to the outside log walls directly.Any thoughts? Also, I have a 4` crawl space under half the cabin.It has block walls, floors are insulated and the ground has plastic barrier.Would it be to my advantage to put any styrofoam on the block walls for better insulating factors?thanks

Heat seeks cold.

When warm moist air comes in contact with an extremely cold object you will get condensation. Weather the cold is on the outside or underside of your home, the cold is traveling through a certain medium (wood or concrete). To stop this you will need a thermal break. A thermal creak consists of a material that will stop or slow the cold AIR migration. Styrofoam will work but try to get a board that is laminated with a vapor/moisture barrier on both sides. Send me your address and I will send you free samples of that material, you can contact me @ microfoil.com or call 602 528-FOIL

Good Luck and Best Regards
