Float glass

This method, invented by Pilkington, was first applied in 1952. Nowadays 90% of all glass is produced using this method. Molten glass is poured onto a bath of tin and, as glass is lighter than tin, it will float on it. This ensures the glass to be perfectly flat, both on the top side and the bottom side. In addition, glass that is produced this way, is extremely flexible.

The materials being used for this type of glass are mainly natural materials, such as sand, lime, dolomite and soda. Other raw materials may be added to the material, which could make the colour of the glass change. This way the glass will fit into any interior and can be applied to any home.

It may so happen that the float glass has a green look. This is caused by the lead content of the glass. When applying extra clear float glass, lead is left out of the glass.

Float glass provides endless possibilities. For instance insulating coatings could be applied to it for protection against cold or heat. If you prefer double glazing which, in addition, has insulating properties, then you can also use float glass. Float glass can be processed into insulating double glazing, laminated glass, tempered glass and curved glass as well.
