Construction Vapor Barrier Poly Film 100" -- 2 mil LDPE | 200 ft/Roll

Clear 2 mil LDPE poly film in a 100-inch wide, 200-foot roll. The wide lay-flat format is designed for large-surface coverage applications including construction vapor barriers, industrial drop cloths, and equipment dust and debris protection. The film can be cut to any length for custom coverage requirements.

Specs: 100" Wide | 2 mil | LDPE | 200 ft/Roll | Clear

Applications:

• Construction sub-slab and crawl space vapor barrier installation
• Industrial and commercial drop cloth for painting, flooring, and renovation work
• Equipment and machinery dust cover for storage or facility maintenance
• Greenhouse and agricultural poly covering applications
• Pallet and large freight dust protection in warehouse environments

Features:

• 2 mil LDPE — durable enough for repeated repositioning and moderate surface abrasion
• 100-inch lay-flat width covers approximately 8 feet — spans standard doorways, equipment footprints, and sub-slab sections
• 200 feet per roll provides continuous coverage for large-area applications without mid-span seams
• Clear film allows visual inspection through the barrier without removal
• Wound on a 3" core for handling and dispensing on roll stands

Material Notes:

Made from LDPE film. LDPE is flexible, moisture-resistant, and tear-resistant under normal handling, making it appropriate for temporary construction barriers and industrial surface protection. At 2 mil, this film handles moderate foot traffic and surface contact during installation. For permanent or extended-use vapor barriers in high-traffic or exposed conditions, a heavier-gauge film (4–6 mil) or HDPE barrier material may be required by local building code.

Use Case Notes:

The 100-inch width is the critical dimension for construction applications — it provides sufficient coverage width to overlap standard framing bays with a single sheet. For crawl space or sub-slab installations, seams should be overlapped a minimum of 12 inches and taped. In industrial environments, the 200-foot roll length allows large machinery, floor areas, or storage zones to be covered without piecing together shorter sections.

Common Questions:

Q: Is 2 mil sufficient for a construction vapor barrier?
A: 2 mil meets minimum requirements for many residential vapor barrier applications. Some building codes specify 4–6 mil for sub-slab or crawl space applications — check local code requirements before specifying gauge.

Q: Can this film be used as a greenhouse covering?
A: Clear LDPE film is used in temporary greenhouse and cold frame applications, though it does not include UV stabilizers. UV-stabilized poly is recommended for applications with prolonged direct sun exposure to prevent rapid film degradation.

Q: What is the total square footage per roll?
A: At 100 inches (approximately 8.33 feet) wide and 200 feet long, each roll covers approximately 1,667 square feet in a single layer.

Why Buy:

200 feet per roll reduces the number of rolls needed for large-area coverage and minimizes mid-span seam overlaps. The 100-inch width covers most standard construction bays and equipment footprints in a single pass, reducing installation labor compared to narrower film formats.
