What is float glass?

Float glass is a sheet of glass made by floating molten glass on a bed of molten metal, typically tin, although lead and various low melting point alloys were used in the past. This method gives the sheet uniform thickness and very flat surfaces.Modern windows are made from float glass. Most float glass is soda-lime glass, but relatively minor quantities of specialty borosilicate and flat panel display glass are also produced using the float glass process.

Application of clear float glass

1).Interior and exterior decoration of high grade buildings: high light transmittance with natural ,transparent artistic, in line with modern design style.

2).Has a higher transmissivity and lower reflectivity, so it can be use as substrates for photoelectric conversion system and solar thermal conversion system panel etc.

3).Display cabinets: can be used as display windows of museums and jewelry store.
