Membrane structure sunshade What is the light transmittance of the building? Membrane structure sunshade building has many advantages that people like. Among them, the transparency of membrane sunshade is well known. This performance is also a highlight of the film structure sunshade. Transparent and easy to analyze

    Membrane sunshade saves energy: the membrane sunshade has a beautiful appearance and creates a natural lighting environment for people. Compared with glass materials and opaque materials, it greatly reduces heat transfer. Reduce the power consumption of indoor lighting and the impact of the use of membrane sunshade on energy issues: in tropical areas, reduce the cooling power consumption of air conditioners; In cold regions, the power consumption of indoor heating equipment increases.

   The film daylighting sunshade has a high daylighting coefficient: the sunlight on the roof is transmitted to the room in the form of scattered light. Starting from the roof, the roof becomes a continuous bright surface, and its intensity varies with the relative position of the roof and the sun. The lighting coefficient (i.e. the ratio of indoor and outdoor natural sunlight) of the indoor space partition of the tensile film structure sunshade can be as high as 10％； In traditional buildings, light can only enter the room from a limited lighting window, and its lighting coefficient is less than 3%. Even on cloudy days, the light intensity of the membrane structure canopy can meet the basic requirements of most activities.

   What is the light transmittance of the film structure sunshade building? Membrane structure sunshade building has many advantages that people like. The transparency of membrane structures is well known. This performance is also a highlight of the film structure sunshade. Today, a simple analysis of the structure of transparent film structure sunshade buildings

   The sunshade with membrane structure has a good sense of color: people in the indoor shed with membrane structure will have a good sense of color for white or gray film materials, because these two colors show the linear spectral transmission characteristics of visible light. The transmission degree increases with the wavelength of the transmitted light, which makes the transmitted light slightly warmer than the incident light. The transmission spectrum is different from the fiber and its characteristics, coating thickness and additional surface layer, and the manufacturer should provide more specific information. Coated with The transmission spectrum of PTFE glass fiber film is relative to that of PVC coated polyester fiber film.

   There is no glare in the film structure canopy: because the transmitted light and reflected light entering the film structure canopy are both scattered light, glare is unlikely to occur. However, the layout and shadow of the glass lighting area must be considered to avoid glare caused by its direct light.
