1. Non-combustibility
2. Performance under sunshine
As the membrane is semitransparent, the sunshine can pass through and be diffused by the membrane, and produce no shadow. The soft and enough light ray help the growth of indoor plants. On the other hand, the ultraviolet rays is prevented by membrane material, so the indoor structure or materials will not discolor because of ultraviolet rays.

3. Performance of Heat energy：
The white color of membrane material can reflect most heat from sunshine, so it can effectively prevent the heat from outside.

4. Mechanical performance：
Generally speaking, the more thin of fiber used for weaving the membrane, the higher tension strength of unit area of the fiber, the thinner woven material that woven by using that fiber.

5. self-cleaning：
Because the membrane surface is laminated with fluoride, and the fluoride is of inadhesion for its physical feature and chemical character, so the dust staying on the membrane surface and various suspended substance in the air can be cleaned by rain. The membrane structure can keep itself clean and save maintaining expenses.
