Duranium®By Aditya Birla Group
World-First Aluminium Alloy
Duranium® is an eternally recyclable aluminium alloy invented by Hindalco, the world's largest aluminium manufacturer. The alloy has been specially developed exclusively for the Coframe range. No other windows in the world have Duranium®.
"Cyclone speeds can exceed 150 km/h and leave windows and homes completely destroyed. Choose wisely. Know your WiWA© score."
Cyclone Shielding
Standard aluminium frames are prone to buckling under high pressure forces. Duranium® alloy delivers extreme deflection resistance, protecting families in coastal high-wind corridors.
