heat-absorbing glass

heat-absorbing glass

A glass whose solar transmittance is reduced by adding various coloring agents to the molten glass; the most common colors are bronze, gray, and green. See also: Glass

heat-absorbing glass

A faintly blue-green plate or float glass, which absorbs 40% of the sun’s infrared (heat) rays and approximately 25% of the visible rays that pass through it; must be exposed uniformly to sunlight (without irregular shadows) to avoid cracking due to nonuniform heating.

During preliminary building design, simulating STPV glass as heat-absorbing glass will impact the final building energy performance and occupants' comfort, as it might result in significant overestimation of the solar heat gains and oversizing of the building cooling system.
EX models are equipped with a panorama roof that extends over the rear seats for an expansive sky view and there is heat-absorbing glass plus an electricallyoperated blind.
Excessive sunlight is filtered by special heat-absorbing glass and a sophisticated shading system, with two fold-out sun blinds.
HEAT-ABSORBING GLASS: Manufactured with special tints, the purpose of this type of glass is to absorb infrared light, which then warms the glass and is transmitted to the interior as heat.
Next, the thermal performance of each type of window system was evaluated from the standpoint of both air-conditioning load and the thermal environment near the windows, including a comparison of glass types other than TP glass, such as heat-absorbing glass, heat-reflecting glass, etc.

Data have been obtained for heat-absorbing glass. This product represents an application where total heat gain might be significantly higher than intuition may suggest because its transmissivity is so low.
