The soda lime glass has a very dark grey color, a total luminous transmission measured for Illuminant A for a glass thickness of 4 mm (TLA4) of less than 20%, and a total energy transmission measured for a glass thickness of 4 mm (TE4) of less than 20%. This glass is particularly suitable for vehicle roof panels.</p> |
