Pictures of Old Skylights in DC
This is a typical old metal and wire glass skylight common in DC in houses from the 1920's to the 50's.
The vent allowed ventalation of the attic space and/or a bathroom.
Designed for an era before air conditioning,
these old skylights are obviously very energy inefficient.
