  11. BCA Requirements • Lighting – Habitable Rooms 10% of room floor area. Must be clear lighting i.e. glass area • Not be closer than 900mm to provide unrestricted lighting

  12. BCA Requirements • Ventilation • All habitable rooms require ventilation • Bathrooms, Laundries also require ventilation • Any other room that be occupied by a person will require ventilation. • Ventilation must be 5% of floor area • If natural ventilation is not possible , mecanical ventilation can be used • Ventilation may be drawn from an adjoining room so long as it not a toilet or airlock

  13. BCA Requirements • Note – Toilet cannot open directly onto a food preparation area without an airlock

  14. Materials • Aluminium

  15. Finishes Naturally when Aluminium oxidises a protective coat is formed to prevent further corrosion. This differs to Iron where the coating formed by oxidisation flakes of and exposes new metal to the elements

  16. Finishes • Anodising • Is the process where this oxidisation process is accelerated and enhanced to build up the thickness off the oxidised layer • Electrolysis in an acid bath is used and dyes are added to provide colouring

  17. Finishes • Powder Coating • Paint is applied dry by use of electrical charges ie paint is a negative charge and the window is positively charged. • The item is then cured by baking to form a hardened skin

  18. Materials • Timber • May be rebated solid sections or hollow box sections • Durable timbers must be used

  19. Solid Frames

  20. Float Glass • Floating molten glass is laid out on molten tin • The molten glass then achieves its desired thickness as it settles under its own weight • A uniform thickness is then achieved

  21. Drawn Sheet Glass • Molten Glass is drawn thru annealing rollers to achieve its size • Some variance will result, giving the appearance of distortion.

  22. Safety Glasses • Float and Drawn glass when broken will leave sharp and jaggered edges which are very dangerous • The BCA limits where can float or drawn glasss

  23. Doors • 3mm & 4mm Float & Drawn glass maximum area 0.1m2 • Maximum width 125mm • Float & Drawn glass not allowed in wet areas

  24. Door Side Panels • 3mm Float & Drawn glass above 1.2 above floor • Below 1.2 above floor no matter thickness max area allowable 0.5m2

  25. View Glazing Handout

  26. Safety Glass Types • Toughened Glass • Laminated Glass • Wired Glass

  27. Toughened Glass • Float Glass is cut to required size • Placed in furnace to just above melting point but not flowing (Gel like) • It is then rapidly cooled causing stressing on the surface particularly on edges • Becomes stronger (4 to 6 times) • Hard impact will cause the glass to shatter into sizes of about the size of 5 cent pieces

  28. Laminated Glass • Two layers of glass held together by a transparent membrane between the glass • When broken the membranes holds the glass sheets together. • Membrane will hold together and hard impact will cause holes

  29. Wired Glass
