What Does the “Openness Percentage” Mean for Solar Shades?

Solar shade fabrics are generally referred to in the context of “opacity” and in percentages of “openness.” Solar shades (and exterior solar shades) operate like roller shades, and are known for providing excellent UV ray blockage (and privacy), while still allowing a view to the outside. They are also known for helping your energy bills (block out heat and light in the summer when closed, or open them in the winter to let sunlight in to help keep your interior warm).

Openness indicates the tightness of the fabric weave, which is an indication of the percentage of light that can penetrate through (e.g. 1%, 3%, 5%, etc.). Low openness means a more tightly woven fabric, with less visibility through the shade and a higher opacity. Higher openness percentages indicate a looser fabric weave, and therefore, greater visibility.

The corresponding number to an openness percentage is the opacity of a fabric: a fabric with 1% openness has an opacity of 99% (97% opacity to 3% openness, 95% opacity to 5% openness, etc.) – the opacity is the percentage of light blockage the fabric is capable of. For more flexibility in managing your interior privacy and incoming light, you may consider dual (or zebra) shades, which display their versatility in combining the functionality of a solid roller shade with the adaptability of horizontal blinds. A layer of sheer stripes alternates with a layer of solid stripes – imagine a continuous fabric shade that you can open and close, as you would window blinds.

Visualizing the Openness Factor

  • Lower openness percentages (e.g., 1% – 5%) block out more of the sun’s UV rays, offering more protection for your furniture/interior finishes, and they also offer more privacy – they do, however, limit outward visibility.
  • Medium openness percentages (e.g., 10%) maintain a good amount of your view to the outside, while still offering suitable protection for your furniture/interior.
  • A high openness percentage (e.g., 14%) provide the best visibility to the outside, as well as decent glare reduction.

Do Solar Shades Provide Privacy During the Day?

Solar shades are effective at reflecting sunlight during the day, so as to block a view into your interior from the outside, while allowing you to see from the inside out. Keep in mind that at night, with your interior lights on, the effect is opposite: the interior light is reflected off of the solar fabric, blocking your outward view, while allowing visibility from the exterior.  

If you should install solar shades and are concerned about privacy, consider implementing a layering effect, by adding opaque curtains between your shade and interior, so you can close them at night to block visibility from the outside.
