  • Coating of the third dielectric layer (27), including ZnAIO x , and the fourth dielectric layer (28), including Si x N y , and the fifth dielectric layer (29), including SiO x N y , and the upper dielectric layer (30), including TiO x , within the mentioned thickness value ranges provides the coating side b* value to stay in the negative region and contributes to the increase of the dominance of blue color in the low-e coated (20) glass (10).
  • the fourth dielectric layer (28), including Si x N y is coated at a thickness which is more than the determined thickness range, the glass side and coating side b* values in the low-e coated (20) glass (10) shift towards“0” and the dominance of the blue color decreases.
  • said fourth dielectric layer (28), including Si x N y is coated at a lower thickness, the coating side a* value in the low-e coated (20) glass (10) increases towards the positive region and the red color increases and thus, this leads to moving away from the targeted color performance.
  • Coating of the third dielectric layer (27), including ZnAIO x , and the fourth dielectric layer (28), including Si x N y , and the fifth dielectric layer (29), including SiO x N y , and the upper dielectric layer (30), including TiO x , within the mentioned thickness value ranges provides the film and glass side reflection values of the low-e coated (20) glass (10) to stay in the targeted performance values.
  • the coating side reflection value of the 6 mm single glass for the low-e coated (20) glass (10) is between 10% and 30%. In the preferred application, the coating side reflection value of the 6 mm single glass for the low-e coated (20) glass (10) is between 15% and 25%. The glass (10) side reflection value of the 6 mm single glass for the low-e coated (20) glass (10) is between 10% and 25%. In the preferred application, the glass (10) side reflection value of the 6 mm single glass for the low-e coated (20) glass (10) is between 15% and 20%.
