Material Advantages in Façade.

  • Ethylene Tetrafluoroethlene
  • Weight 350 gms/sqmtr.
  • Thickness one layer 200 microns.
  • Fire Resistant Class B1
  • Good light transmitance.
  • Life minimum 20 years without loosing transperency & maximum upto 40 years.
  • Non stick in nature.
  • Self Cleaning as no dust adheres to.
  • Can be used in Multiple layers & air blown from inside.
  • High level heat retention.
  • ETFE panels are prefabricated & pneumatically pre stressed ETFE obtains their integrity from air inflation system. Air inflated needs controlled moisture or no dust particles within the gap.
