Description Tjernlund Series Crawl Space Foundation Vents are designed to allow circulation of fresh outdoor air underneath homes and porches. Excessive humidity levels in crawl spaces is the leading cause of premature rotting of support columns, joists, floors and beam supports. Humidity can promote fungus growth and increased termite activity. Humidity may also cause plumbing failures due to rust and corrosion. Our vents provide great solutions to these problems as we specialize in having massive airflow of almost 80%, extreme durability from the use of sturdy galvanized steel, a sleek low-profile design, 18” x 10” perfect size and small holes to close off the space.
