Ultra-low-density grade — the lightest grade Hainuo makes This grade belongs to the Hainuo Ultra-Light series (true density ≤ 0.30 g/cm³). Made from soda-lime borosilicate glass with an inert-gas-filled sealed cavity, it combines very low density, low thermal conductivity, sound and heat insulation, corrosion resistance and excellent flow — ideal wherever weight and heat transfer are critical.
