  • Interestingly enough, this exact usage with windows appears in a much older book, 燃え尽きた地図, on page 325 of the Shinshio paperback edition. Apr 20, 2014 at 5:23

Repeating the same noun twice as inNounというNoun here has the meaning of "all" (definition #5 at Daijisen):

"...all of the windows are being shined on by the evening sun and are sparkling red."

Separately, Time NounというTime Noun can also emphasize time words, but that's a different usage (definition #4 at Daijisen), e.g.:

"today of all days"
