Grommeted Panel

The edges of these panels are sewn with heavy-duty reinforcing tape. Brass grommets are installed on approx. 2' centers around the perimeter. Often includes a seam where two pieces of shade have been sewn together. Durable, easy to install with ropes, bungees or wire. Most durable solution for smaller areas where shade will be suspended between four points. Grommeted panels are sold in pre-cut sizes or can be ordered in any custom size.

Precut Panel

A raw piece of shade fabric where edges of panel are not reinforced with any tape or grommets. Would not typically have a seam but may have a raw (cut) edge. Can be installed with wiggle wire, shade cloth clips or wooden lath. Precut Panels are sold in pre-cut sizes or can be ordered in any custom size.

Bulk (currently viewing)

Sold in factory widths by the linear foot. Would only rarely have a seam and sides typically include a factory finished (uncut) edge. Most cost effective solution for large quantities of shade fabric.

40% density will block out 40% of light. This white polyethylene fabric absorbs and reflects the white scattered light from the atmosphere. The interior of the structure is cooler than that covered by black shade cloth in hot weather conditions, as white shade cloth reflects the heat.

  • Bulk shade cloth has an unfinished edge that does not include reinforcing tape or grommets.
  • Unlike woven shade cloth, the tough, lockstitch construction of our knitted material will prevent unfinished edges from unraveling.
  • Bulk shade cloth can be easily cut with a sharp pair of scissors to any desired size.
  • Bulk pieces can be attached using snap grommets, zip ties or other fastening methods.

Hanging Instructions

When hanging shade cloth pieces larger than 100 sq. ft., you may need extra center support to prevent the cloth from sagging in the middle. One easy way to do this is by running lightweight cable from corner to opposite corner, forming an X pattern that the cloth can rest on. For pieces larger than 400 sq. ft., you may need cables running end to end every 4' or so.

  • excellent for growing greens
    I bought this to cover raised beds that get too much midday sun and go to seed too quickly. I attach it to PVC pipe bent over the bin in the form of an arch and it works great to limit sun exposure and keep out birds who like to nibble the greens

    Product gets a 5 star rating but shipping gets one so we ended up with three stars. It's a great product, tough, durable and very useful. I bought some before to shade my newly planted seedlings from excessive heat where it works very well and we no longer loose any from overheating with such unstable weather. Also use it on our hoop house. Bought more this year. Delivery was more of a problem. First I got no notification on when the stuff was arriving. It came by freight carrier and the guy could not get his semi truck up our farm driveway so we had to unload on the road. Then the box they used fell apart and we ended up stuffing all the cloth into the back up our pickup to get it back to the farm. Driver was very nice and helpful but it was still a pain for all of us.Letting us know when the delivery was due would have been good cant expect the driver to wander around the farming looking for someone. Such a light parcel did not really need to come freight anyway perhaps they wanted to save money on the terrible box!
  • Wonderful product!
    I've been after my husband for 10 years to get some cover over our 2nd fl deck. It is a complicated space and he finally figured it out and got it up. The cloth makes an enormous difference to both the house and my shade loving plants. We love it!
  • Excellent Products
    The shade cloth is perfect. It comes in unfinished lengths so that I can finish edges myself.
  • Gardener
    ordered for my 8 x 30 greenhouse. Made a lot of difference and I wish I had used it earlier. I attached it to the overhead trusses. Good stuff.
  • Bulk 40% shade cloth
    We use the 40% shade cloth in our greenhouse and it cools the greenhouse plus protects the plants from burning. The bulk cloth material is good quality and the pricing is competitive.
  • 40% white shade cloth
    The material was cut to size easily with scissors and fastened to 1/2 inch electric metal tubing with plastic fasteners to make a roof on a hoop house. It's working great so far, only a month or so, but looks like it should last quite awhile.
  • good stuff
    This has met my needs very well. I was able to cut it to the needed size with no unraveling. It stays clipped to the sides of the raised beds, withstanding winds well. Being able to water thru the cloth saves me time. My veggies are so happy to have the sun protection in our hot climate. This is superior to the remay I had bought, which shredded within a month. I hope it lasts a long time, as it was quite an expense for me. I'd have liked to be able to track the shipment, but it did arrive OK.
  • Shade cloth in New Mexico
    Works well for blocking the harsh sun in southern New Mexico. Vegetables grow much better with this shade cloth. Seems durable so far - does not rip in high winds.
  • Great shade cloth
    The bulk screen cloth is a fantastic. Much larger sections than available locally at a great price. The plastic gromits to attach a rope around the edges also work great.
  • Great Stuff
    After weeks of temps over 100, my garden is so grateful to finally have this shade cloth. It's miracle stuff. I've got it clamped to a PVC hoop house with your Snap Clamps including the metal second piece, and that holds it fine in our sometimes 60 mph winds. I was using row cover but it got shredded in the wind. This is so much sturdier; I have high hopes of it holding up in a hailstorm. I love how the edges don't fray despite no finish. For now the plants are cooler and happier and may even set fruit! My order arrived sooner than expected and was generously cut--thank you!
