Light transmittance is one of the most widely recognized characteristics of modern membrane structure architecture. The light transmittance of the membrane material can provide the necessary luminosity for the building, which plays a very important role in building energy saving, but the light transmittance of membrane structure film is still very few people know, so this article is for the film structure membrane material light transmittance for everyone to do an introduction.

Membrane structure of the membrane material has a good light transmittance, this is because the film material transmittance is determined by its basic fiber, coating. The standard film material projection ratio is between 10% and 20%, some of the film material transmission ratio reached 40%, for some require light and high brightness of commercial buildings and so on is particularly important. Through the comprehensive utilization of natural daylight and artificial light, the transparency of membrane material can provide more aesthetic creative space for architectural design. Through the appropriate combination of membrane material and transparent insulation material, can make the film containing the insulation layer has light transmittance. Even though the film's projection ratio is only a few percentage points, the membrane structure is still shiny and translucent to the human eye, with a light roofing membrane.

The tensile stress of the membrane itself is combined with the supporting rod and the cable to form the tissue system. In the light of the sun, the building covered by the membrane filled with natural diffuse light, no strong contrast between the smooth and shadow of the difference between the indoor space visual environment open and harmonious. At night, the lights of the building illuminate the night sky through the membrane of the roof, and the body of the building shows a dreamy effect. The membrane structure is particularly suitable for building the city's symbolic roof, such as sports and entertainment venues, advertising-effect shopping malls, restaurants and so on. The city's transportation hub is the key construction of the city lifeline, and the symbolic clarity of the various components of the construction of the utility demand. As a result, more and more membrane structures have been selected for this type of construction in recent years. Because the application life of membrane structure is more than 25 years. In the use of time, under the effect of snow or wind load can adhere to the information of the mechanical shape stable. But the membrane structure of the building should also pay attention to, that is, the indoor sun exposure time is too long, will make the indoor temperature gradually rise, affecting the normal activities of people in the building
