"As much as twelve gallons of moisture vapor can be released from the soil into the crawlspace of a 1,000 square foot house in a single day."

VaporFree® Crawlspace Systems prevents problems associated with vented crawlspaces, such as:
  • Insect infestation, such as spiders and termites
  • Standing water
  • Mold and decay
  • Poor indoor air quality
  • Energy loss
  • Hardwood Floor Cupping




VaporFree® crawlspaces are a better choice because they manage moisture, ensuring that the crawlspace remains drier decreasing the likelihood of mold and decay. In addition wood is stronger when it is drier, therefore the structure is better.



Sealing a Crawlspace with VaporFree®

Moisture management and control in the crawlspace is essential for maintaining the structure. Crawlspaces fitted with traditional foundation vents are particularly vulnerable to moisture and other problems.

From a psychrometric standpoint, venting a crawlspace to remove moisture only works when the outside air is drier than the crawlspace air. “Drier” does not mean lower relative humidity, but rather a lower absolute humidity. Relative humidity is a ratio of the amount of moisture in the air relative to the amount of moisture the air can hold at a given temperature.
