9Mil Heavy-Duty Clear Woven Greenhouse Plastic, 6y UV, Anti-Drip, 195gsm

9 mil woven greenhouse plastic is a heavy-duty covering material that combines a thick polyethylene layer with an embedded woven scrim (grid pattern) for reinforcement. The '9 mil' refers to the thickness (0.009 inches or 0.23mm), making it significantly more durable than standard 6 mil film.

Woven plastic offers several advantages over standard 6 mil film: 4+ year lifespan vs 1-2 years, tear-resistant construction that prevents rips from spreading, better wind resistance, and more stable installation due to its weight. While it costs more upfront, the reduced replacement frequency provides significant long-term savings.

With proper installation and care, 9 mil woven greenhouse plastic typically lasts 4-6+ years. The UV stabilization protects against sun degradation, and the woven scrim reinforcement prevents the tears and stretching that cause standard films to fail prematurely.

Yes, our 9 mil woven plastic includes UV stabilizers throughout the material. This protects both the plastic itself from sun degradation and provides some UV filtering for your plants. The UV treatment is rated for 4+ years of outdoor exposure.

Our 9 mil woven clear plastic provides 85%+ light transmission, ensuring your plants receive optimal sunlight for healthy growth. The woven scrim pattern provides slight light diffusion, which can actually benefit plants by reducing hot spots and providing more even light distribution.

Measure the width of your greenhouse frame from ground to ground (over the top), and add 12-18 inches on each side for proper overhang and secure fastening. For length, measure the total length and add at least 2 feet on each end. When in doubt, order slightly larger - you can always trim excess, but you can't add material.

Yes! We offer custom cutting for both width and length. Contact our sales team at (541) 605-3555 with your specific dimensions, and we'll provide a quote for your exact requirements. Custom orders typically ship within 3-5 business days.

Our 9 mil woven plastic is available in widths up to 50 feet. For greenhouses requiring wider coverage, you can overlap multiple pieces using proper seaming techniques, or contact us about custom welded panels for seamless coverage.

We recommend 12-18 inches of overhang on all sides for proper installation. This allows adequate material for securing with wiggle wire and channel, and provides a buffer for any installation adjustments. More overhang is always better than not enough.

Installation involves: 1) Mounting poly lock channel to your frame, 2) Draping the plastic over the structure on a calm day, 3) Securing with wiggle wire starting at the ridge and working down, 4) Pulling the plastic taut as you go, 5) Trimming excess material. Watch our installation video guide on this page for detailed instructions.

Essential supplies include: Poly Lock Channel (aluminum or PVC), Wiggle Wire (stainless or galvanized), self-tapping screws for channel mounting, and a utility knife for trimming. Optional but helpful: Poly Repair Tape for any accidental tears, and an extra set of hands for draping the plastic.

Yes, 9 mil woven plastic can be installed DIY with 2-3 people. The material is heavier than standard film, which actually makes it easier to handle in wind. Choose a calm day for installation, watch our how-to videos, and have all supplies ready before you start. Most hobby greenhouses can be covered in a few hours.

Absolutely! Poly lock channel (also called wirelock or base channel) is the recommended attachment method for 9 mil woven plastic. The channel mounts to your greenhouse frame, and wiggle wire secures the plastic into the channel without any punctures that could lead to tears.

The best method is using poly lock channel with wiggle wire along all edges where the plastic meets the frame. For ground-level edges, you can bury the plastic in a trench, use ground stakes, or attach to a baseboard. Avoid using screws or nails through the plastic, as this creates weak points that can tear.

Yes, 9 mil woven plastic is designed for year-round use in all climates. It performs well in temperatures from -40°F to 180°F. The material remains flexible in cold weather and resists degradation in hot conditions, making it suitable for all seasons.

Absolutely. 9 mil woven plastic is rated for use down to -40°F and performs excellently in cold climates. The material stays flexible even in freezing temperatures, and many of our customers use this product in northern states and Canada where winters are severe.

While 9 mil woven is much stronger than standard film, we recommend minimizing walking on the plastic. If you must walk on it during installation, wear soft-soled shoes and step carefully. The woven scrim provides significant puncture resistance, but sharp objects or heavy concentrated weight can still cause damage.

Clean your greenhouse plastic with a soft brush or cloth and mild soap solution. Rinse thoroughly with water. Avoid abrasive cleaners or brushes that could scratch the surface and reduce light transmission. Regular cleaning helps maintain optimal light levels and extends the material's lifespan.

Standard sizes typically ship within 1-3 business days. Custom cut orders usually ship within 3-5 business days. During peak season (spring), lead times may be slightly longer. Contact us for current availability and shipping estimates for your specific order.
