7) Spandrel Gass - graphicote

8) Insulating Glass - two or more sheets of glass

9) Tinted Glass

10) Reflective Glass

11) Low-e Glass - low emissivity, reduces heat transfer

12) Photocromic Glass - changes color thru sunlight

13) Thermocromic Glass - changes color thru temprature

12) Electrocromic Glass - smart glass

Glazing

The panes or sheets of glass or other transparent material made to be set in frames, as in windows, doors, or mirrors.

Types of Glazing
