| Low-e glazings use a thin, metallic oxide coating deposited on the glass to reduce radiant heat loss through the window. |
|
| Solar transmissivity in new windows is controlled through the use of tinted or coated glazings. |
|
| To further enhance the energy saving qualities of the windows, non-metallic spacers are used between the glazings. |
|
| We provide methods to analyze new kinds of systems such as radiant heating and cooling, electrochromic glazings and daylighting. |
|
| Other glazings are designed to resist explosions or impacts, preventing the window glass from becoming flying shrapnel. |
|
| Although these coatings can produce similar savings, they do not have service lives comparable to that new glazings. |
|
| While some glazings, such as low-emissivity ones, result in no significant change, others can dramatically alter it. |
|
| Also coming are smart glazings, notably electrochromics, which use low-voltage power to modulate from clear to full color. |
|
| Most chromogenic glazings are still in the development stages and not yet available for large-scale commercial projects. |
|
| Fire-rated glazings in fire doors must be in place with no damage. |
|
| A wider PMV interquartile range, in particular with higher values for high SHGC glazings and larger window areas, is in accordance with this. |
