Industry knowledge of Etfe membrane cutting machine：

While a single ply ETFE membrane has an approximate U value of 5.6 w/m2K, a standard three layer cushion can achieve a U value of 1.96 w/mK a better insulation value than triple glazing when used horizontally (glazing manufacturers figures are for vertical glazing which considerably enhances the figures). The insulative qualities of ETFE cushions can also be improved by the addition of more layers of foil (up to five in total) or by treating the foil with specialist coatings to enhance the thermal properties.

ETFE Foil is naturally a very transparent material and transmits light across the entire visible light region (380-780nm). A single layer of medium weight ETFE has an approximate 85% light transmission, although multiple layers will lead to a small reduction.

Transmission across the ultraviolet range (320- 380nm) is also very good (approx 83-88%) and therefore allows plants and vegetation underneath to thrive.  It is also important to note that the film absorbs a large proportion of infra red light transmitted, a quality which can be exploited to improve buildings energy consumption.
