Healthy Homes for Mississippi — Gulf Wind, Shifting Clay, Delta Damp
Virtual Home Health Score assessments statewide. GaiaCrete™ detailed for Mississippi's Zone 2A-3A humidity and coastal wind-borne debris rules. Founding Mr Hemp House® dealer territories open by ZIP code.
Post-Katrina coastal wind standards
Mississippi Gulf Coast construction carries elevated wind and elevation requirements, and the envelope has to keep driving rain out at those speeds.
Expansive Yazoo clay movement
Shrink-swell clay across central Mississippi cracks slabs and opens envelope joints, giving humidity and pests a path indoors.
Delta humidity and mold
Mississippi Delta dew points sustain mold growth in any assembly that holds water, including ducts in unconditioned space.
What Climate Zone 2A-3A Means for Mississippi Homes
Mississippi is hot-humid from the Gulf Coast Zone 2A through Delta and northern Zone 3A counties, with a cooling season that rarely lets a wall dry. Gulf Coast counties still build to post-Katrina wind and elevation standards. Expansive Yazoo clay under the Jackson area moves foundations enough to open the very joints that keep water out.
Mississippi statewide adoption of the IRC and IECC
Mississippi adopts the residential and energy codes statewide, with additional wind-borne debris requirements in coastal counties.
