Double Shading

Nowadays, weather extremes are making it hard for growers to provide enough shade for plants in the summer and enough temperature control in the winter using the same shade structure. In some areas, the amount of shade needed in the summer may be higher than what is readily available from suppliers.

So, what can your customers do?

The Benefits of Double Shading

Double shading is a solution that may help growers combat the weather extremes that have become more prevalent in many areas. Essentially, double shading utilizes two shade fabrics to provide a higher or variable amount of shade for plants. This process can also be used to reach a more specific or optimal shade factor for plants that may be very sensitive to extreme sun or heat. Double shading allows growers to customize their shade for each plant and season if needed.

While some growers layer two fabrics directly over each other, other growers prefer to suspend one layer of fabric above the first to allow additional airflow. Using separate hanging systems for each layer of fabric can also allow the grower to provide more shade during the hottest season and then roll back the amount of shade during the winter months when the sun is less extreme.

While a simple calculation can be used to estimate how much shade would be provided by layering two fabrics, it is important to verify the amount of shade with individual testing that also accounts for how the fabrics will be layered and installed. We have put together a chart based upon calculations that reflect the estimated shade protection provided when layering two fabrics.

To use the above table:

  1. Locate the shade percentage of the first layer of fabric you intend to use along the left horizontal axis (i.e. 55).
  2. Follow the row across to find the desired shade percentage (i.e. 88).
  3. Follow the column up to locate the shade percentage that should be applied as the second layer (i.e. 73).
