Proper Vapor Barrier Installation in Crawl Spaces - Best Practices #3869498 (License: Personal Use)

This image shows a well-installed white vapor barrier lining the floor and partially up the concrete foundation walls of a crawl space, beneath exposed wooden floor joists. The barrier is sealed at seams and edges to minimize moisture infiltration, and fiberglass insulation batts are visible between joists. Such installations help control humidity, improve energy efficiency, and protect against mold and wood rot.

Used on home improvement, HVAC, and foundation repair websites to illustrate proper moisture control techniques in crawl spaces; targets DIYers and contractors seeking guidance on preventing water damage and improving indoor air quality.
