This is a summary of a study of the subfloor moisture levels of south Louisiana raised foundation homes with six different insulation systems. It also includes the resulting recommendations – all intended to help homeowners, builders, architects, insulation contractors, home inspectors and others balance energy efficiency, comfort and durability issues. Among the issues addressed are:

  • Why does moisture management matter?

  • Types of crawl spaces
  • Managing rainwater and soil moisture
  • Water vapor movement
