    • PROBLEM TO BE SOLVED: To build a pleasant room space by providing a spacer between two sheets of translucent membrane bodies for restricting the distance between the membranes within a predetermined range and placing translucent sol, gel or a liquid in a space created between the membranes. SOLUTION: A translucent membrane material comprises two sheets of membrane bodies 1, 1 and a spacer 2 arranged between the membrane bodies and a silicone oil 3 as a translucent liquid filled in a space formed between the membrane bodies 1, 1. As stated above, sol, gel or a liquid is filled between the membrane bodies, and the sol, gel or liquid having a density higher than the membrane material raises the overall density of the translucent noise insulating membrane material, thereby improving the noise insulating performance of the translucent membrane material. Also by the spacer 2, the thickness of the translucent film material does not become non-uniform by region. Thus, the room space built with the translucent membrane material gives more comfortableness to the tenants compared to the conventional membrane material.
