How to choose the opening rate of Sunscreen?
The opening rate is the ratio of holes interwoven by the warp and weft of the sunshade fabric.Using the same color, diameter of the fiber weave the same texture, the small hole rate of shielding solar radiation heat and control glare irradiation ability is stronger than the large hole rate.
How to choose the opening rate of Sunscreen?
(1)The sunshade screen fabric with 1% to 3% opening rate can block the heat generated by solar radiation to the greatest extent and control glare, but the natural light will enter less and the transparency effect is relatively poor.Therefore, it is usually recommended to use 1% to 3% of the sunshade fabric in some southern and western Windows with strong sun exposure, and usually use a larger area of curtain wall glass and daylighting roofs to solve the strong thermal radiation and harsh sunlight exposure.
(2)The shading fabric with 5% opening rate is the most widely used, in the general shading project, it can block solar radiation, control dazzling exposure, and obtain natural light and good transparency.
(3)10% of the open rate of the solar screen fabric, you can get good natural light and excellent transparency, but compared to 3% and 5% of the fabric, the resistance to solar radiation and glare performance is poor. It is usually recommended to use north facing Windows and curtains in the interior of the room, or shading in the library.
