Foundations are rectangular metal vents that sit just above the dirt line on your exterior of a home. With little effort, these can be opened and closed for airflow especially in tight crawl spaces where minimal circulation is present. This passive airflow creates cleaner and fresher air providing you with much sought-after relief from dirty or stagnant odor which people may get used to over time if they’ve been confined indoors for long periods.
Foundation vents help to improve crawlspace conditions by allowing the humidity to get out from under the house in the warm months and by keeping good, dry heat in during cold months.
