During the Float Glass manufacturing process, molten glass, at approximately
1100°C, is poured continuously from a furnace onto a large bath of molten tin.
It then floats on the tin, spreading and seeking a controlled level surface. In
the controlled production process, the molten glass is allowed to spread to a
width of 300 to 360 cm, depending on the glass thickness being produced. The
thickness is controlled by the speed at which the slowly solidifying glass
ribbon is drawn through the tin bath. After about 120 m of travel through the
cooling Lehr, it emerges as a continuous ribbon of glass at merely room
temperature. The product is perfectly flat and has virtually parallel surfaces.
Automatic cutters are used to trim the edges and to cut across the width of the
moving glass ribbon. This creates sizes which can be shipped or handled for
further processing.
ExtraClear™ Plus provides formative advantages in comparison with
standard float glass. Particularly it is characterized by a higher transparency and a more natural color. Guardian’s ExtraClear™ Plus glass is ideal where high visibility
and clarity are required. ExtraClear™ Plus is suitable for almost all glass
applications and finds appreciation from architects, investors and consumers. It
can be heat treated or laminated for safety glazing. ExtraClear™ Plus is suitable for screen printing, acid etching, and decorating with ceramic materials. Its outstanding photospectrometical performance allows also technical application such as solar and thermal collectors.
