Vented Crawl Space Insulated in Beaver Bay, Minnesota

This Beaver Bay crawl space was vented which allowed the unconditioned air from the outdoors to freely enter under the home. In the winter these vents could be shut, but it was not providing an air tight seal necessary to block out the cold winter air. To fix this issue when we encapsulated the crawl space we filled the vent area with insulation and used spray foam insulation to seal the space and prevent air from leaking through.
