VAPOR BARRIERS

When You Have Moisture And Mold,

WHAT IS A VAPOR BARRIER?

A vapor barrier, or vapor retarder, is construction grade polyethylene sheeting, that is most notably installed along the floor of a crawl space. It covers the exposed earth under a home, with no less than 12 inches of overlap along all of the adjoining seams

Yes, every crawl space should have a vapor barrier. Vapor barriers are a crucial element for any home with a crawl space. You can expect relative humidity levels to be 40-50% higher, and wood moisture levels as high as 25%, in a crawl space without a vapor barrier.

COMMON PROBLEMS WE SEE EVERYDAY DUE TO INSUFFICIENT VAPOR BARRIERS:

  • A vapor barrier does not provide complete ground coverage, allowing moisture and odors from the ground to rise into the crawl space and home.
  • Moisture and standing water on top of the vapor barrier. A result of a rising water table during heavy rains, and poor drainage around the foundation.
  • Condensation forming, due to high humidity, on the AC unit and duct work under the house. That condensate builds, dripping onto the vapor barrier, soaking into the wood joists where the ducts hang, and soaking into the sub-floor where the vent registers connect to duct work. Overtime, this leads to mold, musty odors, and even wood rot along the joists and sub-floor.
  • Musty smells in your home or crawl space are likely a result of insufficient ground coverage or an ineffective vapor barrier. Mold is often a result of high humidity, temperature, and wood moisture levels in the crawl space.
  • Damaged and hanging fiberglass insulation is often a result of insufficient vapor barrier coverage. The insulation can be easily damaged by moisture and humidity, and will diminish in r-value over time when exposed.
  • Failing North Carolina home inspections and independent home inspections is often a result of inadequate vapor barrier coverage or having no vapor barrier at all.
