String-Reinforced Clear Poly Sheeting 20' x 100', Wide Tear-Resistant Vapor Barrier for Crawl Space, Under Slab & Construction Enclosures

For large, high-abuse coverage, string-reinforced 20' x 100' clear poly sheeting offers wide, tear-resistant protection in one roll. This scrim-reinforced construction film is perfect for vapor barriers under slabs and across crawl spaces, big dust containment walls, and rugged enclosures where wind, movement, or contact is inevitable. The 20-foot width reduces seams and makes it easier to cover broad spans quickly. Worried about standard film ripping too easily? The internal reinforcement grid helps stop rips from spreading, dramatically extending the life of enclosures and barriers. Use it for restoration projects, materials storage covers, and large jobsite partitions that must stand up to traffic and handling. Clear reinforced film keeps areas bright and visible for crews, inspectors, and equipment operators. For serious jobsites where regular plastic just doesn’t last, this is a dependable, heavy-duty choice.

• 20' x 100' string-reinforced clear poly sheeting provides wide, tear-resistant coverage for larger construction and restoration projects.
• Heavy-duty vapor barrier for crawl spaces and under slab, designed to resist punctures and tear spread during installation and use.
• Excellent for large dust containment walls and enclosures, especially where wind, equipment, or frequent contact can strain standard films.
• Clear reinforced film supports sightlines and light transmission so crews can see stored materials and work zones behind the barrier.
• Extra-strong woven scrim reinforcement helps extend service life on tough jobs, reducing replacement frequency and labor.
