  1. Glass

  2. Ordering Glass • Contractual Requirements • Statutory Requirements

  3. Ordering Glass • Contract Requirements Are these requirements above the NCC

  4. Statutory Requirements • National Construction Code (NCC) • Development Controls by Certifying Authorities • Development Applications (DA) • Development Control Plans (DCP) • Other • Health Care • Child Care etc

  5. National Construction Code • Volume 2 Class 1 &10 Performance Requirement

  6. NCC Acceptable Construction Manuals

  7. NCC Acceptable Construction Practice

  8. Deemed to Satisfy (DTS)

  9. Deemed to Satisfy (DTS)

  10. Development Control • Development Application

  11. Barriers

  12. Class 2 to 9 Building • NCC Volume 1

  13. BASIX

  14. Ordering • Client/Contract Requirements • Statutory • NCC • Govt. Bodies • Certifying Authority • BASIX

  15. Glass Properties

  16. Manufacturing Tolerances

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

  18. Annealing

  19. Breakage Characteristics of Annealed or Float Glass

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

  21. Breakage Characteristics • Dependant on Glass used in the panes

  22. Toughened Glass

  23. Thermal Toughening

  24. Thermal Toughening

  25. 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

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

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

  28. Chemical Toughening

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

  30. Disadvantages

  31. Laminated Glass

  32. Breakage Characteristics • Binding layer will hold fragments

  33. Stamping
