The minimum plastic thickness for a vapor barrier in construction is generally 6 mil (0.006 inches). This thickness effectively prevents moisture transmission, protecting structures from mold and damage. Use reinforced polyethylene for added durability and resistance. Ensure proper installation by sealing seams and edges to enhance performance. For specific applications or regions, consult local building codes or a professional to verify compliance and effectiveness tailored to your needs.
