insulating glass<br />
In units with multiple glass plies, it is<br />
important to specify the specific glass<br />
substrate for each ply. When a tinted glass<br />
substrate is selected typically only one ply<br />
of the fabricated glass unit is tinted while<br />
the other ply remains clear. The tinted ply<br />
should be placed to the exterior to reduce<br />
solar heat gain.<br />

laminated glass<br />
One exception is laminated glass.<br />
Since there is no airspace to keep the<br />
heat absorbed by the tinted exterior<br />
ply from re-radiating into the building,<br />
the solar heat gain can be improved by<br />
moving the tinted ply to the inboard.<br />
This improvement happens when the<br />
clear coated outboard with high solar<br />
reflectance is placed in front of the tinted<br />
glass.<br />
