Float glass window characteristics
Windows made of float glass are the most common one, float glass optical characteristics are limited so these windows are mostly used in lighting applications. See below float glass specifications detail :
| Material name | Float Glass |
| Material detail | Soda-lime glass |
| Index of Refraction | 1.52 |
| Transmission range | 0.35µm to 2,7µm |
| Density | 2.53 g/cm3 |
| Hardness | 585 Knoop |
| Young’s modulus | 74 GPa |
| Thermal expansion | 9.5*10-6 °K-1 |
| Softening point | 564°C |
| Melting point | 1000 °C |
In order to strengthen the window annealing is possible.
Float window usage
For lighting protection, can be used in wide range of industry:
- transport
- urban lighting
- construction
- equipment
Silkscreen and ceramic printing can also be added for cosmetic usages.
