Temp-Vent foundation vents are designed to provide
ventilation that can reduce moisture in these areas, which helps
A crawl space dehumidier with no drain or power needed!
Whenever possible, vents should be placed on all sides of the
foundation. This will create an intake/exhaust system that
delivers a steady flow of air. One vent should be installed for
each 8 to 10 feet of foundation wall.
Most building codes require 1 square foot of open ventilation
area for every 150 square feet of crawl space. Temp Vent
Automatic Foundation Vents have 50 inches of net free area per
vent. Therefore, you should install one vent for every 50
square feet of crawl space.
For crawl spaces with polyethylene installed, on 80-90% of
the ground, the ventilation requirement changes to 1 square foot
of ventilation for every 500 square feet of crawl space with a
minimum of 4 vents installed to provide cross ventilation. For
crawl spaces with polyethylene, install at least one vent for
every 500 square feet of crawl space.
Automatic Foundation Vents
The non-powered, Automatic Foundation Vent will open and
close automatically using a heat/cold sensitive coil. The
louvers open completely at approximately 72įF and completely
close at approximately 38įF. Unlike manual vents that can waste
energy when no one remembers to open or close them, these vents
self-adjust all year long.
