| Heat Absorbing Glass |
||
| Glass demonstrates outstanding efficiency in lowering
levels of solar radiation and minimizing glare | |
 A Bank In Tokyo |
| Heat absorbing glass is tinted float glass manufactured with small amounts of admixtures such as iron, cobalt or selenium. Heat absorbing glass absorbs more solar radiation than does transparent float glass, and it moderately suppresses the transmission of infrared, visible, and ultraviolet light rays, thereby resulting in a proportional improvement in the efficiency of air-conditioning units. | | |

 |
Interception of solar radiation |
| It reduces the load imposed on air-conditioning units. | |
| Glare prevention |
| It minimizes glare by absorbing a large amount of the light rays in the visible spectrum. | |
| Discoloration resistance |
| It absorbs a certain amount of ultraviolet light to retard discoloration
of furniture and goods. |

Calculate thermal values and follow the standard glazing procedures; as these products absorb a large amount of solar energy, they can be easily affected by thermal stress. |
|
Calculate thermal values when a reflective film covers the interior surface of the glass. This film permits the glass to re-absorb reflected solar energy, raising the temperature in the center area of the glass. |
|
The sashes molded in pre-cast concrete curtain walls may generate serious thermal cracking due to temperature differences between the exterior and interior surfaces of the glass. |
|
Damaged glass edges can generate thermal cracking. Use only glass units that have been cleanly cut. Use a sander of #120 mesh or above to smooth the edges. |
|
Glass units should not directly contract the sashes. |
 | |
| Three water drain holes (5 mm in diameter) must be provided at the sash bottom for draining rainwater or condensation quickly. |
| Use a superior elastic sealing compound (polysulfide or silicone). |
|
Use polyethylene foam or chloroprene rubber as a backup material. |
|
Provide setting blocks of chloroprene rubber (90° hardness) at two places along the bottom edge. |
 |
|
| The glass surface should not be painted or coated with paper. |
| The glass surface should not be exposed to direct currents of air from air-conditioning units. |
|
If the glass surface is shielded by thick curtains, shades, lockers
or other objects, the temperature at the center of the glass will
rise and thermal cracking can occur. Curtains and other shields should
be at least 100 mm away from the surface of the glass. |
