Be careful with insulation installation.

Mold is becoming such a big problem because people think they can overrule Mother Earth and put in plastic and other impenetrable barriers to stop moisture. It ain't going to happen!

Go with insulation that breathes and although it may not be as efficient, it beats the hell out of tearing down a house that has mold culture behind all the walls.

On a "This Old House" show they showed a house being built in Switzerland. The thing that caught my eye and attention was how they built the exterior wall leaving bottom and top openings for air flow. If I ever build a house or addition, I intend to put up such outside walls. Technology that works with nature is better than trying to fight with nature.

My personal belief with no scientific backing that I know of would be to paint the inside walls with a good latex paint and leave non-breathing vapor barriers completely out of the picture.
