BASIC TYPES OF FLAT GLASS USED IN THE BUILDING INDUSTRY
Float Glass (also known as annealed or raw glass)
This is the finished product as it comes off the float line. It has a bright, fire-polished surface and is optically virtually distortion free. It is relatively brittle and will break when subjected to a severe blow or load. Float glass break is undesirable - slivers of large pieces may cause injury.
Consists of two or more pieces of float glass, firmly united and alternately one or more interlayers of either liquid resin or polyvinyl butyral. Will crack under impact, but the fracture does not cause the glass to separate from the interlayer, therefore will not cause severe injury.
Normal float glass which has been converted into structural glass by a process of heating and rapid cooling. Process produces a glass 4-5 times stronger than normal float glass of same thickness. Toughened glass (the strongest type of glass available) is more resistant to impact and thermal shock than annealed glass. Fragments are harmless, as they disintegrate into small pieces with blunt edges.
Incorporation of metal fabric in wired glass. Two ribbons of glass converge and meet with a wire netting fed in between them. Wired glass is more brittle than normal glass of same thickness.
As glass ribbon passes between rollers, the pattern/design is pressed onto one surface of glass. By changing the one roller, different patterns are achieved. This glass has the same break pattern properties as normal float glass.
We have a range of glazing contractors, large and small, with the skills and experience to handle any size project.
