Heavy Float Glass Is defined as glass thicknesses greater than 6mm (1/4"),

Heavy float glass offers some distinct advantages over the traditional 6mm (1/4") used in architectural applications.

Characteristics

Heavy float glass has increased strength and deflects less
In certain wind load areas where glass surface optics are critical, annealed heavy float glass may be specified instead of heat-strengthened or tempered glass. Heavy float glass can be used as an exterior pane in an insulating glass unit in combination with a thinner interior pane to reduce the exterior distortion which normally occurs in insulating glass

Applications

Commercial glazing for windows and doors .Storefronts and entrance ways, handball and squash courts, aquariums, hockey arenas, railings, glass floors, office partitions, glass shelves, basketball backboards, tabletops
