Suitable Glazing Selection for Glass-Curtain Walls in Tropical Climates of India
Table 1
Different kinds of glass-curtain walls used in this study. The values of both U and g have been computed by WINDOW 5.0.
| S. no. | Glazing type | Description | Identity | U (W/m2K ) | SHGC* (g-value) |
| 1 | Double glazed, clear glass window | 6 mm clear glass + 12 mm air space + 6 mm clear glass | Clear-clear | 2.95 | 0.73 | 2 | Double glazed, low-e window | 6 mm low-e glass + 12 mm air space + 6 mm clear glass | Low-e1-clear | 1.80 | 0.68 | 3 | Double glazed, low-e window | 6 mm low-e glass + 12 mm air space+ 6 mm clear glass | Low-e2-clear | 1.74 | 0.54 | 4 | Double glazed, solar control (absorptive) window | 6 mm solar control (absorptive) glass + 12 mm air space + 6 mm clear glass | Solar control-abs | 2.80 | 0.24 | 5 | Double glazed, solar control (reflective) window | 6 mm solar control (reflective) glass + 12 mm air space + 6 mm clear glass | Solar control-ref | 1.95 | 0.10 |
