  19. Benefits of Using Local Glass • Complies with local & International Standards • Stock availability • Quick replacements • Prompt technical support • Survival of local industries • Reduced carbon footprints

  20. VARIABLES The many window innovations available today require a designer to make selections in at least 16 different variables

  21. 1. GLASS THICKNESS • 2.5, 3, 4, 5, 6, 8, 10, 12, 16, 19 mm 10

  22. 2. TINTS: • Low-Iron Clear, Clear, Green, Blue-Green, Blue, Bronze, Light Grey, Grey, Dark Grey 9 90

  23. 3. COATINGS:Visible Absorbing • Visible Reflective • Visible Color (Gold) • Low Emittance • Solar Absorbing • Solar Reflective • Solar Transmitting • Self-Cleaning • Anti-Reflective • Other (UV Block, Anti-Graffiti) 10 900

  24. 4. HOW MANY LIGHTS? • Single Glazing Double Glazing Triple Glazing Add-On Panels 4 3,600

  25. 5. IG SPACER • Aluminum, • Partly Insulating, • ‘Warm Edge’ • 3 10,800

  26. 6. Gas Fill • Air, • Argon, • Krypton • 3 32,400

  27. 7. GLASS STRENGTH • Annealed, • Heat Strengthened, • Tempered 97,200

  28. 8. IMPACT RESISTANCE • Laminated 0.015” pvb • Laminated 0.030” pvb • Laminated 0.060” pvb • Laminated 0.090” pvb • Colour interlayer • Impact Resistant Interlayer • Acoustic Insulating Interlayer • CIP (Cast in Place Epoxy Laminate) • 8 777,600

  29. 9. LAMINATION ORIENTATION • Coated plies: • Coating to air side OR • Coating against interlayer (pvb etc.) • n.b. Low-E coatings touching the • interlayer lose their low-e property • because glass is opaque to Far IR! • 2 1,555,200

  30. 10. FIRE RESISTANCE: • Wired Glass, Intumescent Laminates - • 20, 30, 60, 90, 120 minutes Fire Rating • 5 7,776,000

  31. 11. ELECTROCHROMIC: • Switch between High & Low SHGC.Switch between Transparent & Translucent. 2 15,552,000

  32. 12. ELECTROMAGNETIC SHIELDING: • Prevent electronic data escaping.Prevent interference entering. • Different db shielding levels 3 46,656,000

  33. 13. ORIENTATION OF OUTER LIGHT • 2 93,312,000

  34. ORIENTATION OF INNER LIGHT • 2 186,624,000

  35. ORIENTATION OF IGU • Everyone should use hand-held coating • detector meters • 2 373,248,000

  36. That makes about millions different combinations!ONE is the best. All others are likely less than best. • HOW DO YOU CHOOSE?

  37. CONCLUSIONS • Glazing choices are many and varied • IG gas fills and some coatings (4 at least) are invisible • You cannot see by eye: U-Factor or SHGC • There are tools, codes, standards and certification programs available • Which bring us to low e, energy savings, and green issues….

  38. Glass for Malaysia • How do you choose? • Performance issues • Look of the building • Energy Savings • Green initiatives • Many, many factors

  39. TECHNICAL INFORMATION 40

  40. The 4 Energy/Heat Flows Remember: Heat Flows from Hot to Cold 3% 47% UV Visible Solar IR Far IR 50%

  41. Heat Flows from HOT to COLD Conduction Convection Radiation

  42. U-Factor measures the rate of heat transfer from warm air side to cool air side. Watts/sq.m.degC Far IR Radiation Conduction Convection

  43. SHGC Solar Heat Gain Coefficient % of Sun’s heat striking a window that enters a room (by conduction + convection + radiation) Far IR Radiation Solar IR Radiation Convection

  44. Shading Coefficient % of Sun’s heat striking a window that enters a room (by conduction + convection + radiation) Compared to % of Sun’s heat striking a 3 mm Clear Glass window that enters a room (by conduction + convection + radiation) SHGC ~ 0.87 x Shading Coefficient Shading Coefficient is a Poor # to use…Why? Whose 3mm glass? Why not 6mm? SHGC is a pure formula and preferred.

  45. Heat enters when the sun shines through the glass: SHGC (Solar Heat Gain Coefficient) or SF or S/C About half as much enters over a 24 hour day by conduction (U-Factor, or K factor) for 15 °C difference (40 °C outside, 25 °C inside) Adding Low Emissivity always helps because it lowers SHGC and it lowers U-Factor

  46. Three Numbers are needed: • Tdw for fading control. (Free from LBNL Windows 5 http://windows.lbl.gov/software1 to 0. Lower means less fading. ) • SHGC for Solar Control (or SF or Shading Coefficient x 0.87 Lower value means less solar heat gained inside the building from sun shining on the window) • U-Factor for thermal control(or U-Value, K Factor. Conversion: 1Btu/hr.sq.ft.°F = 5.68 Watt/sq.m.°KLower value means less heat flow by conduction from warm to cold)

  47. WHAT TO DO: • Select Glass for appearance, daylight transmission, color, reflectivity, etc. • Add a Low Emissivity property, and add a light of glass, for better Solar control if a solar absorbing layer is present. • For better Thermal control add Low-E, and add a light of glass (double glazing)

  48. Glass Energy is Either: Transmitted Reflected Absorbed The Flow of Visible and Invisible (Infrared) Energy from the Sun. Glass, Light, & Heat

  49. 3mm monolithic CLEAR 100% 6% Reflected Out 86% Transmitted In 7% Absorbed (Emitted Out) 1% Absorbed (Emitted In ) • 8% Total Rejected 13% 87% Total Admitted Typical Glass Energy Characteristics OUTDOOR INDOOR
