The improvement of the space environment performance of membrane structure material can increase the layer number of the membrane structure material, can combine the membrane structure with different spectral transmittance, fire resistance, permeability and so on, and make use of the advantages of the membrane structure to get more extensive application. Double-layer membrane structure is the most common one multilayer membrane structure. The choice of membrane structure in general should be comprehensive consideration of fire protection, anti-seepage, lighting and sound insulation requirements, the air layer of the double layer reduces the membrane structure of the outer membrane and the internal closed space due to convection generated heat transfer, thus achieving thermal insulation effect.

The insulating film structure material is a sandwich membrane structure material which is filled with a layer of light insulating material between the inner and outer membrane. The common insulation material consists of foam layer, fiber mat, bubble film, etc., they have different light transmittance and heat preservation performance respectively. Porous, fluffy, lightweight insulation membrane structure material can greatly reduce the heat transfer through the surface of the membrane structure, so as to achieve the control of indoor space temperature.
