Warp's Poly-Cover Construction & Agriculture Film - 1.5mil - 4ft x 1,000ft - Black

Lightweight Sun-Blocking Ground Cover Film for Temporary Jobsite Use, 4ft x 1,000ft

A plastic sheeting with no recognized certification leaves contractors guessing whether it will actually hold up as a drop cloth or light-duty barrier on a real job. Warp's Poly-Cover Construction & Agriculture Film is seamless, full-weight polyethylene sheeting rated to ASTM D-4397 and built to NBS PS17-69 and Handbooks 130 and 133, and this 1.5mil black version adds a light-blocking finish for temporary outdoor use.

At 4ft x 1,000ft, this long, narrow roll suits temporary covers, drop cloths, and light-duty moisture barriers where a lighter gauge is enough for the job.

Key Features & Benefits

• Lightweight 1.5mil Gauge — sized for temporary covers, drop cloths, and light-duty vapor or moisture barriers rather than long-term structural use.
• One-Piece Roll Construction — ships as a single continuous run rather than multiple seamed sections spliced together.
• Sun-Blocking Black Finish — blocks light transmission for weed suppression, mulching, and outdoor ground covers where light exclusion matters.
• ASTM D-4397 Rated — meets ASTM D-4397 along with NBS PS17-69 and Handbooks 130 and 133 for construction and agricultural sheeting.
• Made in the USA — produced at Warp Bros.' Chicago and Dixon, Illinois plants rather than imported.

Who Should Use This Film

This lighter gauge suits contractors, landscapers, and growers who need a temporary cover, drop cloth, or light-duty moisture barrier rather than a heavy structural liner — a long 1,000ft roll length that reduces how often a run needs to be pieced together.

About Warp Bros

Warp Bros. has manufactured plastic sheeting since 1924, when founder Harold Warp patented an early plastic glazing product and began production in Chicago, Illinois. The company still runs its polyethylene film and plastic sheeting lines domestically, from plants in Chicago and Dixon, Illinois.

Frequently Asked Questions

How thick is 1.5mil, and what jobs is it suited for?

At 1.5mil, this is the lightest gauge in Warp's Poly-Cover line, built for temporary covers, drop cloths, and light-duty vapor or moisture barriers rather than long-term structural applications. Heavier mil ratings hold up better to repeated handling and extended outdoor exposure.

Is this film independently rated for construction use?

Yes. It meets ASTM D-4397 requirements alongside NBS PS17-69 and Handbooks 130 and 133 for polyethylene sheeting, the specifications commonly referenced in construction and agricultural applications.

Why choose black film instead of clear?

The black finish blocks nearly all light transmission, which makes it the better choice for weed suppression, mulching, and outdoor ground covers where keeping light off the covered surface is the goal. Clear film is the better pick when some light transmission is useful, such as concrete curing.

Can this film be used around greenhouses or growing areas?

Yes, growers commonly use this film as a ground cover, floor liner, or light-duty vapor barrier around growing areas. Its ASTM-rated polyethylene construction holds up to routine handling in those settings.
