An encapsulated or “sealed” crawlspace is a more energy efficient alternative to the traditional wall-vented crawlspace. If your home is built on a crawlspace, chances are you have open foundation vents in place.
Key Benefits of Crawlspace Encapsulation
More Energy Efficient
Improves Indoor Air Quality
Increased Home Value and Eye Appeal
Adds Usable Space to the Home
Helps to Prevent Freezing Pipes
Control Foul Odors
Helps to Keep Hardwood Floors from Cupping and Buckling
Control Conditions for Mold Growth
Locks Moisture Away in the Soil
Helps to Keep Floors Warmer in the Winter
Many Georgia homes have crawlspace vents which allow air to circulate beneath the home. Originally designed to control humidity in the crawlspace, these vents actually have been shown to increase humidity rather than to decrease it here in the humid Southern climate. Think about it: in the summer months, the outside air is usually hot and humid. When a crawlspace is wall-vented, the same hot-humid air outside is passing through through into the cooler crawlspace, causing the air to condense, leaving condensation on the floor joists and air ducts.
Excess condensation leads to mold, fungus, and foul odors in the crawlspace. Crawlspace vents need to be closed to seal out unwanted humid air. Dirt crawlspaces also need a proper vapor barrier installed on the floor and exterior walls. An encapsulated crawlspace will properly control humidity, leading to a healthier and more energy efficient home.
