15. Glass Properties

16. Manufacturing Tolerances

18. Annealed or Float Glass Molten Glass Laid on Molten Tin Slowly Cooled to reduce induce compressive forces – (Annealing)

19. Annealing

20. Breakage Characteristics of Annealed or Float Glass

21. Insulating or Double Glazing Multiple Glazing Filled with air or Argon Used for Acoustic or Thermal Requirements

22. Breakage Characteristics Dependant on Glass used in the panes

23. Toughened Glass

24. Thermal Toughening

26. Toughness Toughened Glass is Tougher that Float Glass Toughened Glass is more brittle Toughened Glass will shatter – Care should be used when using it as a barrier

27. Toughened Glass Internal Layer cools slower External cooled rapidly External Layer is drawn into internal layer Large compressive force formed (>60mpa)

28. Breakage Characteristics Stressed Surface cause it to shatter & crumble in < 5mm

29. Chemical Toughening

30. Breakage Characteristics Will break in the same manner as annealed glass

31. Disadvantages

32. Laminated Glass

33. Breakage Characteristics Binding layer will hold fragments

34. Stamping
