Common questions
What thickness of poly sheeting do I need for my application?
4-mil thickness is the industry standard for heavy-duty applications including equipment protection, construction site coverage, and moisture barriers. It resists punctures and tears better than 2-mil or 3-mil alternatives while remaining cost-effective for commercial use. For temporary light-duty uses, thinner options are available; for extreme durability, 6-mil is recommended.
Can I use this poly sheeting as a moisture barrier for walls?
Yes. Clear 4-mil polyethylene is an effective temporary or permanent moisture barrier for walls, crawl spaces, and foundation protection. Its clarity allows you to monitor areas behind it, and the 4-mil thickness prevents moisture penetration while resisting punctures from rough surfaces.
How much area does one roll cover?
One roll covers 2,000 square feet (20 feet wide x 100 feet long). Calculate your coverage needs by multiplying the length and width of areas you plan to protect, accounting for overlaps at seams if covering large spaces.
Is this product compliant with construction and shipping regulations?
Yes. 4-mil clear polyethylene meets standard construction and industrial packaging requirements for moisture barriers and protective coverings. Always verify specific project or shipping regulations with your local authorities, as requirements vary by application and jurisdiction.
