The openness of sunscreen fabric refers to the rate of small holes interlaced by warp and weft of shade fabric, using fibers of the same color and diameter to weave the same texture.The ability to block solar radiant heat and control glare with a smaller aperture ratio is stronger than that with a large aperture ratio.
Fabrics with a 1% to 3% openness can block the most heat created by solar radiation and decrease glare, but they let in less natural light and have a poor light transmission impact. As a result, we normally advocate utilizing it in certain sun exposure directions (such as the west) and when the curtain wall is composed of transparent glass to avoid intense thermal radiation and bright sunlight.

Customization is acceptable for all given values. |
◈ Shade, light, and ventilation. It can eliminate up to 86% of solar radiation while keeping indoor air unobstructed and a clear view of outdoor scenery.
◈ Insulation. The sunshade fabric has good thermal insulation properties that other fabrics do not have, which greatly reduces the utilization rate of indoor air conditioners.
◈ Anti-UV shade fabric can resist up to 95% of UV rays.
◈ Fireproof. Low fire resistance and high fire resistance can be customized according to the different user requirements.
◈ Moisture-proof. Bacteria cannot multiply and the fabric does not go moldy.
◈ Constant size. Sunshine fabric’s material determines that it is not malleable, will not deform, and maintain its flatness for a long time.
◈ Easy to be cleaned, it can be washed in clean water.
◈ Good colorfastness.
