Float glass

For 4000 years, basic glass has been made of the same basic materials: quartz sand, lime, soda and dolomite. The float glass method has become established worldwide for the production of construction glass. This is a sensitive process where the basic materials are melted at great heat; the viscous mass is then "floated" over a tin bath and cooled down very slowly.

Here are some of the product attributes of float glass as made and used today at NOWAK GLAS:

  • Can be combined with all function glazing together with laminated or toughened safety glass
