I may have asked this before but need to understand. The home I am speaking of is in the NorthWest section of Alabama.
How much of the "crawl space"/with dirt floor, be covered by vapor barrier? Should the "vapor barrier" cover the outer foundation walls? Should the "vapor barrier" be secured at sill/cement foundation and wood connection?
I do have vent holes in foundation for proper ventilation, they are now covered with styrofoam to keep out moisture but I am removing these foam blocks and installing "mosquito netting/ to keep out critters and insects. I am also installing new access doors w/same netting. I know that home has to "breath" so I do not want to block all vents with foam unless necessary. Is this correct process or does someone have expert advice on what is proper procedure?
