Keep Crawl Spaces Drier with envirofoam closed cell foam insulation:
The practice of adding vents to crawl space walls is
meant to help dry out the crawl space area. However,
vents actually allow moisture to enter the crawl space,
and do little to help it dry out.
Moisture that enters through these vents clings
to floor joists, batt insulation, HVAC equipment
and plumbing fixtures. In this moist environment,
mold and mildew can quickly degrade the space's
contents, as well as compromise indoor air quality.
In addition, wood-eating insects, dust mites and
small creatures can enter through the vents to take
up residence.
A popular alternative to the vented crawl space
is the unvented, properly insulated crawl space.
Spray foam insulation serves an important role
in an unvented crawl space, helping keep the
area dry and the home more energy efficient.
