How much does shade cloth reduce temperature – Most of the shade cloth will reduce the temperature between 10% and 30%.
But It depends on quite a few factors such as:
wind speed, the humidity of the air, the sunlight’s angle, and the surrounding climate.
It also depends on the type of shade cloth, the material it’s made of, the color, and of course, shade cloth density percentage.
I know this is not a specific answer.
But to answer more accurately, I contacted all the manufacturers for an answer.
Also, there is nothing like a customer’s own experience.
It is highly recommended to read the conclusions I wrote at the end of the article.

How Much Does Shade Cloth Reduce Temperature? Companies Answers:
I turned to quite a few shops and manufacturers.
I want to mention two companies that answered my questions quickly and meticulously:
Poly-Tex, Inc. & Palram
GALE Pacific company (Colorado products)
A few companies promised to check and get back to me, and I’ll update as soon as I get an answer.
GALE Pacific company (Colorado products) answer:
An HDPE shade cloth would reduce the temperature by up to 22°F in 95°F and around 16°F at lower temperatures.
I would note that other factors such as wind speed, the humidity of the air, and the sunlight’s angle will also play a factor. However, these are reasonable estimates.
I would recommend HDPE because we exclusively use HDPE.
Note that more common materials such as PVC/Acrylic have a Proposition 65 warning in California. They contain dangerous compounds and are often deemed unsafe for use around foods/baby toys.
Another added benefit of HDPE is it is fully recyclable as well.
30% UV Block and 50% UV Block fabrics are best for gardening and horticulture.
Poly-Tex, Inc. & Palram answer:
There is no exact heat rating for our shade cloth, as that would vary greatly depending on the surrounding climate.
The shade cloth would significantly diffuse light, creating a light transmission rating of only 40%. This will significantly assist in reducing heat buildup within your greenhouse.
Any of our units can be suited for vegetables or plants, and it is more a matter of the surrounding climate.
A greenhouse is best used as a tool to help facilitate temperatures for the greenhouse.
Sometimes a thicker panel is needed in a colder region, while thinner panels are perfectly sufficient in warmer climates.
We know it would reduce light by 60%, creating optimum shade for the vast majority of plants or vegetables.
Shade Cloth Temp Experiment
the 2 test’s before you were made in the middle of the summer.
The first test is on a “shade cloth aluminet 40%”.
TEST A
measurement of the ground temperature – without shade cloth = 119°F.
ground temp without shade cloth
Measurement of the ground under the shade cloth aluminet 40% = 95.5°F.
Ground temp under the shade cloth aluminet 40% Result
result: a decrease of 20%.
Measurement of the leaf temperature without shade cloth = 87°F.
the heat of the leaf without shade cloth
Measurement of a leaf under shade cloth aluminet 40% = 74.5°F.
leaf under shade cloth aluminet 40%
result: a decrease of 14%.
TEST B
The second test is on a “black shade cloth 40%”.
Measurement of the ground temperature – without shade cloth = 119°F.
ground temp without shade cloth
Measurement of the ground under the “black shade cloth 40% = 83.5°F.
measured on the ground below the black shade cloth 40%
result: a decrease of 30%.
Measurement of the leaf temperature without shade cloth = 87°F.
the heat of the leaf without shade cloth
Measurement of a leaf under “black shade cloth 40%” = 80°F.
The temperature is actually 80 degrees until I was measuring, the sun moves
result: a decrease of 8%.
The Effect of Cloth Characteristics on the Cooling Performance of External Shade Cloths for Greenhouses
Four shade cloths were examined for their ability to reduce temperatures in a greenhouse:
-a black flat-weave shade cloth rated by the manufacturer at 30% shade.
-a black flat-weave shade cloth rated at 55% shade.
-and black knitted shade cloth rated at 50% shade.
-a white knitted shade cloth rated at 40% shade.
The cloth was examined both dry and wet.
The dry, 40% shade cloth, white knitted cloth reduced the rate of energy gain, air temperature rise, and electrical energy consumption by more than the dry black cloths.
Leaf temperatures were lower under the heavier black cloths (but not the 30% shade) than under the white.
When dry the heavier black cloths performed better than the 30% shade black cloth in all respects, except air temperature rise, where there was no difference.
When wet, both the 55% and 50% shade, black cloths performed better in all respects than either the 40% shade, white or the 30% shade, black.
The knitted 50% shade cloth, black cloth performed marginally better than the flat-weave 55% shade, black cloth in several categories, despite a lower shade rating.
This was attributed to differences between the two fabrics in the dependence of shade factor on incidence angle.
How Much Does Shade Cloth Reduce Temperature Summery
I hope I’ve been able to assist you with how much does shade cloth reduces the temperature.
There are so many criteria, and it is tough to answer accurately.
When you find what is suitable for you, I assure you that your plants and vegetables will flourish.
| Side note: In the area between 70°F to 80°F.
Photosynthesis is optimal for most plants. |
There is no substitute for trial and error.
You can buy your first shade cloth manufactured in China (they are cheaper).
If it works for you, buy a higher quality, manufactured in Europe or the USA.
I’d love it if you share your experiments with shade cloth with me.

Good luck!
