Ordering Glass • Contract Requirements Are these requirements above the NCC
Statutory Requirements • National Construction Code (NCC) • Development Controls by Certifying Authorities • Development Applications (DA) • Development Control Plans (DCP) • Other • Health Care • Child Care etc
National Construction Code • Volume 2 Class 1 &10 Performance Requirement
Development Control • Development Application
Class 2 to 9 Building • NCC Volume 1
Ordering • Client/Contract Requirements • Statutory • NCC • Govt. Bodies • Certifying Authority • BASIX
Annealed or Float Glass • Molten Glass Laid on Molten Tin • Slowly Cooled to reduce induce compressive forces – (Annealing)
Insulating or Double Glazing • Multiple Glazing • Filled with air or Argon • Used for Acoustic or Thermal Requirements
Breakage Characteristics • Dependant on Glass used in the panes
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
Toughened Glass • Internal Layer cools slower • External cooled rapidly • External Layer is drawn into internal layer • Large compressive force formed (>60mpa)
Breakage Characteristics • Stressed Surface cause it to shatter & crumble in < 5mm
Breakage Characteristics • Will break in the same manner as annealed glass
Breakage Characteristics • Binding layer will hold fragments
