Production of float glass involves the pouring of molten glass from a furnace onto a large, shallow bath of liquid tin. The glass floats on the tin, spreading out and forming brilliant, polished flat surfaces, with the thickness controlled by the speed at which the solidifying glass is drawn from the tin bath. The glass then travels an annealing line where the cooling process continues under controlled conditions. It emerges in one continuous ribbon, which is then cut to suit customer requirements.
Clear float glass is predominately used in windows, shopfronts and some furniture and can be further processed into laminated, toughened, coated and painted glass, double-glaze (IG) units and mirror.
Tinted glass is produced by adding metal oxides such as iron, cobalt and selenium to the clear float mix. The addition of these oxides, which are very stable and fade resistant, provide the glass it’s colour and improves the solar performance without changing the basic properties of the product. Standard tones include Grey, Green, Bronze and Blue.
The benefits of tinted glass include:
- Heat & glare control
- Low external reflectance
- Improved energy efficiency
These benefits make tinted glass ideal for use in windows & doors, furniture or incorporated in laminated glass or double glazed units.
