Heat reflecting roof

The roof is consists of 4 layers of ETFE foil (3 air chambers). The outer layer is heat reflecting by using a special IR blocking foil. This foil is light transparent but blocks effectively the heat from sun shine (see below graph ''T IR-cut'').

Below graph shows the relation between Transmission and Wavelength of light for standard foil (''T Standard natural") and IR blocking foil (''T IR-cut'').
