How These Vents Work

Foundation vents help maintain healthy airflow in crawl spaces by allowing moisture to escape, which is especially important in preventing mold and mildew buildup. The automatic function ensures the vents close when temperatures drop, keeping your home energy-efficient and protected year-round.

Properly installed foundation vents act as a barrier against pests such as rodents, insects, and small animals that could otherwise enter your crawl space and cause damage.
