T&G (Tongue and Groove)
A vapor barrier is a material used to prevent moisture from passing through walls, ceilings, and floors. It is typically made of polyethylene sheeting or foil and is installed in areas prone to high humidity, such as basements and bathrooms. Vapor barriers help protect against mold and mildew growth by controlling moisture levels in a building. Proper installation is critical to ensure effectiveness, as any gaps or punctures can compromise the barrier's performance. At Westman Lumber Supply, we provide high-quality vapor barrier products suitable for various construction applications.
