Soda Lime Float
DESCRIPTION
| Soda lime float glass is manufactured in a wide variety of sizes and thicknesses to 0.4 mm. The manufacturing of thin and extra-thin glasses according to the float process guarantees optimal surface evenness, minimal variation in thickness and, within a single batch of glass, lower thickness tolerances than those obtained through any other manufacturing process. |
