Visqueen 20 x 100 Clear 6 Mil Visqueen

This 6-mil polyethylene sheeting delivers 2,000 square feet of coverage at the minimum thickness contractors trust for vapor barriers and protective applications. At 20 feet wide by 100 feet long, each roll weighs 23-35 pounds of heavy-duty LDPE plastic.

The clear sheeting works across Montana jobsites — from crawl space moisture barriers to concrete curing covers. The 6-mil thickness meets the minimum standard for vapor barriers, making it suitable for protecting crawl spaces, basements, and under concrete slabs. Applications range from construction moisture barriers and dust containment to painting drop cloths and temporary weatherproofing.

Coverage Specs and Material Properties

Each roll covers 2,000 square feet with 6-mil (0.006 inch) thickness polyethylene. That coverage handles a 40x50 foot crawl space or protects multiple concrete pours. The material comes in clear LDPE with a translucent/milky appearance rather than crystal clarity.

The sheeting functions as an effective moisture barrier while allowing visual inspection of covered surfaces. The LDPE material resists puncturing and tearing during medium-duty use while remaining flexible enough to shape around obstacles.

Moisture Protection and Jobsite Applications

Professional contractors rely on 6-mil Visqueen for vapor barriers in crawl spaces, basements, and under concrete slabs. The material meets ASTM D4397 for construction applications, ASTM C171 for concrete curing, and ASTM D2103 for polyethylene film specifications.

Construction uses include moisture barriers under concrete slabs, crawl space protection, temporary wall sealing, and dust containment. The sheeting also works for covering fresh concrete during curing and serves as heavy-duty drop cloths for painting projects.

For temporary weatherproofing, the clear material seals windows and doors against wind and rain while covering firewood, lumber, or outdoor equipment. Montana contractors appreciate products that handle multiple tasks — this sheeting transitions from summer concrete work to fall weatherproofing without missing a beat.

Installation Requirements

The 20-foot width requires two-person handling for unrolling, but cuts easily with a utility knife or heavy-duty scissors. For vapor barrier installations, overlap seams by at least 6 inches and seal with construction-grade tape.

The sheeting works on wood, concrete, drywall, soil, metal, and plastic surfaces. Compatible adhesives include duct tape, painter’s tape, and specialized vapor barrier tapes, with the material suitable for crawl spaces, basements, and general jobsite use.

While 6 mil handles most applications, contractors note it might not suffice for environments requiring extreme durability or long-term exposure where thicker materials prove preferable. The clear material isn’t UV-stabilized — it’s not recommended for permanent direct sun exposure unless specifically UV-treated.

Value Analysis

This 6-mil sheeting costs approximately 40-50% less than comparable 6-mil products while delivering professional-grade performance. Customer feedback highlights excellent value for the coverage area and effectiveness at blocking moisture and drafts.

Standard retail returns run 30 to 90 days depending on the retailer, with most poly sheeting sold ‘as is’ for general use. Major brands like Poly-America offer limited warranties against manufacturing defects.

The 2,000 square foot coverage at 6-mil thickness hits the sweet spot for Montana construction. Crawl spaces need reliable moisture protection through freeze-thaw cycles. Concrete needs proper curing coverage. This sheeting handles both without breaking budgets.

Some manufacturers produce their sheeting using recycled polyethylene, though performance remains consistent regardless of recycled content. Common complaints include the milky appearance rather than crystal clarity and UV sensitivity that causes brittleness after several months of sun exposure.

FAQ

How much area does one roll cover? Each 20 x 100 foot roll provides 2,000 square feet of coverage.

What’s the actual thickness? The sheeting measures 6 mil thick, which equals 0.006 inches.

Does this work for crawl space vapor barriers? Yes — 6 mil meets the minimum standard for vapor barriers in crawl spaces, basements, and under concrete slabs.

Can one person install the 20-foot width? No — the 20-foot width requires two people for easier handling during unrolling.

What tape works for sealing seams? Construction-grade tape including duct tape, painter’s tape, or specialized vapor barrier tapes all create effective seals.

How long does it last outdoors? Standard clear Visqueen becomes brittle after 6-12 months of direct sunlight unless specifically UV-treated.
