Grommeted Panel (currently viewing)

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.


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% shade allows 60% light transmission. Aluminet is a special knitted screen made from metalized HDPE giving the fiber durability and longevity. These properties allow Aluminet to function like a mirror during summer months as its unique aluminized fibers reflect unwanted sunlight and heat from your greenhouse. These same properties also serve to retain valuable heat during the winter months. The shade is designed especially for internal use to be spread permanently as a ceiling beneath greenhouse roofs, or to be installed as a moveable thermal screen.

  • Fabricated pieces include black reinforcing tape on all four sides. Reinforcing tape is a seat belt like material that provides extra durability along the edge of the piece and allows installation of grommets.
  • Fabricated sizes include a brass grommet in each corner of the piece and approximately every 2' apart around the entire perimeter. Grommets allow easy installation using rope or zip ties.

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.

  • Shade cloth
    So far has helped cool greenhouse 10 degrees
  • No coating and ripped after one year
    Doesn't last long at all. Very disappointed.
  • Lasts less than one year under optimal conditions
    These aluminet shade cloths are pretty expensive for something that starts breaking down and almost completely loses efficacy within less than a year. Absolute garbage in my experience
  • Fantastic product
    After years of suffering from extremely high temperatures in the greenhouse, we added a thermostatically controlled exhaust fan and this 40% Aluminet Shade cloth from Greenhouse Megastore. I installed it on the outside of the greenhouse and it has made a huge difference. I'd recommend it highly.
  • perfect for the Southwest
    40% Aluminet Shade Cloth was the answer to my Southwest garden. I finally have a successful garden
  • Reflective shade cloth
    My plants are thriving even in 90' heat
  • Excellent temperature control
    The shade cloth dropped the temperature in my greenhouse by 15 to 20 degrees and my plants are so much happier. The fans don't have to run as much and that saves on the power bill.
  • Just what I needed
    The 40% aluminet fabricated shade cloth was just what I needed in my small greenhouse. The cloth was easy to install with the grommets that were in the perimeter of the cloth. Cable ties and a length of light PVC tubing was all that was necessary.
  • Aluminum Shade Cloth
    Excellent product. Helps to keep it warmer and cooler.
  • Perfect Shade
    Installed 2 of the panels side by side on the interior of just the southern exposure on my 12X24 greenhouse roof. Very lightweight and simple to install and cuts easily to get around fans, ighting, vents, etc. Also has good flexibility and stretch. The 40% shade dropped the temp an easy 20+ degrees. I haven't needed to activate the exhaust fans yet and it is mid-May! My only suggestion would to be add a few more grommets. Would buy again.

  • Awesome Shade Cloth
    Very cool...shade cloth. I love it! Perfect for my carnivorous plants at 40% AND it is reflective to keep the heat down! Thank you GMS!
  • 40% Aluminet, Great Product!
    Living in western Colorado, and over 5000 feet in elevation, the sun can get quite intense; not to mention the heat that reaches into the upper 90's to low 100's during late spring and summer. Makes it hard on plants inside our greenhouse, where temperatures are 15-25 degrees hotter than outside, even with a 20 inch exhaust fan with shutters.Not wanting to lose/cook any of our plants, I got on the internet and typed in Greenhouse shade covers and stumbled on to this site. I called for information about the Aluminet shade covers, and was recommended that I need the 40% cover, if we use the greenhouse for vegetables, which we do.I ordered it, and when it came-in I was very surprised on how light weight it was/is. My wife and I said, this doesn't look like it would do anything. We were wrong!The cover came in a small box, weighing around 7 pounds and some odd ounces; it took me very little time to install it on our 12' wide X 8' high X 24' long greenhouse.All I can say is, it works great! It holds the temperature at, or near the outside temp, and the vegetables and other plants are thriving. We also turn-on the 20 inch vent fan when temps get in the upper 80's. Long story short, we love it and would/will buy another when needed.
  • Sun protection worth the extra cost.
    This stuff has protected my toms in record breaking 110+ heat. Not one yellow leaf, they're just as lush and green as they were back in April. Going to order more and cover the rest of my garden next year.
  • Aluminet Shade Cloth
    Very pleased with the Aluminet Shade Cloth. Used as a permanent cover over my raised garden. Great customer service and it arrived quickly.
  • Great product
    Awesome product, allows for some sunlight to penetrate the green house.
  • 40% Aluminet
    Works great. My 576 sqft greenhouse gets full afternoon sun with outside temperatures of 105+and after putting up the 40% Aluminet temperatures inside the greenhouse dropped from 125+ to around 110-115.
  • Does A great job
    Does a great job at helping keep the temperature down. Tough job in the southern heat. Reasonably priced.
  • aluminet rshade
    I have a 10x12 greenhouse still producing in mid Nov. Cloth was very easy to put up and virtually weightless. The color blends in and not offensive to neighbors. Highly recommend.
  • Happy With My Purchase
    Stitching and grommets look to be high quality. Can't find this product locally, price was comparable if not better than other websites.
  • Best Greenhouse Shade Cloth
    This is a really nice product for orchids. What a difference it made. Plants responded within a week. You get all the light and less heat. This shade cloth really works!!
    We live in the desert southwest, and even on comfortable days, the sun can be brutal. The aluminet has eliminated my worries of cooking my plants. In fact, they are thriving beyond my wildest dreams. Some of the best money we have spent!
  • Very happy with my purchase!!
    I ordered a custom shade cloth (40% Aluminet) from IGC on April 14th on the recommendation of a fellow Phoenix gardener. At first I was a little worried as they say they can only guarantee the custom size you order within +/- 4. However, when I received my shade cloth on May 2nd, it was the EXACT size ordered and I couldn't be happier with the entire transaction. The cloth is very well constructed and is working hard to keep my veggies cool in the desert heat. The reps were a pleasure to deal with and the cloth arrived sooner than I expected. We have since ordered a second custom Aluminet shade cloth and are eagerly awaiting it's arrival. Very happy with my purchase!
  • Flexible fabric and flexible function
    Flexible fabric and flexible function. My enclosed greenhouse is 42 feet long and it contains a diverse mix of vegetables with different sunlight requirements. I got many smaller panels of fabricated Aluminet Shade cloth so that I can manage the sunlight requirements for the different plants. By lacing panels together I can control the heat while leaving some areas open for those plants with full sun requirements. When the cool weather leafy stuff is done and replaced with the warmer weather plants, I���ll simply adjust the placement of the shade cloth panels, adding or removing panels where necessary.

  • great product and service
    Our homemade hobby greenhouse was too hot to work in or grow plants in during the summer - installed this product in July and brought the temps from 100+ to upper 80s; our greenhouse is usable again! We bought ours fabricated and installed it with cable ties. The cloth was not a dense as it appeared to us in the pictures and is not heavy. It is performing just as advertised. The representative we spoke with over the phone was knowledgeable, courteous, efficient; web order was easy. We'll buy from Greenhouse Megastore again.
  • Exceptional value
    I checked the internet for shade cloths and the cost of this one is excellent. Great customer service and very happy with the quality and how quickly I received the item. I highly recommend Greenhouse Megastore.
