They are usually used together with other fabrics to cover objects to avoid contact with strong light. They have the functions of blocking strong light and ultraviolet rays and other aspects. Building shading products refer to devices installed on buildings to block or adjust the sun entering the room. They are usually composed of shading materials, supporting components, adjustment mechanisms, etc. By reducing the ultraviolet rays, glare and heat radiation of the sun to the building, the convection between the hot air generated by the sun and the building is blocked. In addition to the uses of energy saving and heat preservation, sunshade and light shading, building shading also has the functions of rain protection, insect protection, cold protection, moisture protection, wind and sand protection, and sound insulation and noise reduction. Modern building shading products can be divided into functional shading and traditional shading products.
