12 Mil Crawl Space Vapor Barrier with Thick Polyethelene Double-Sided Plastic Sheeting - 10” x 100”

When crawl spaces face high humidity levels, heavy traffic during installation, or long-term exposure risks, you need protection that’s built for more. 

The heavy-duty Argendon 12 Mil Crawl Space Vapor Barrier is thicker and stronger than standard liners, and provides exceptional protection against moisture, mold, and soil gases. Ideal for lasting foundation protection in crawl spaces and areas that require long-term installations.

High Durability

Constructed from premium-grade polyethylene with advanced anti-aging additives, this 12 mil vapor barrier offers superior puncture and tear resistance. Its reinforced thickness ensures it performs in the toughest crawl space environments, even during rough handling or repeated inspections. 

Double-Sided Protection

Built for demanding environments, this 12 mil vapor features a black-and-white dual-sided design that delivers both durability and visibility:

• Black side locks out light to minimize microbial growth and preserve foundation integrity.
• White side maximizes brightness, reflecting up to 90% of light for safe, efficient access.

This innovative two-in-one functionality ensures lasting results in even the toughest conditions.
