What does 窓という窓 mean?


What does 窓という窓 mean? I found it in this sentence in Harry Potter:

> 木の扉に寄りかかってホグワーツを見上げると、窓という窓が夕日に照らされて赤くキラキラ輝いている。




Repeating the same noun twice as in`NounというNoun` here has the meaning of "all"
([definition #5 at
Daijisen](http://dictionary.goo.ne.jp/leaf/jn2/154743/m0u/%E3%81%A8%E3%81%84%E3%81%86/)):

> …窓という窓が夕日に照らされて赤くキラキラ輝いている。  
>  "...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](http://dictionary.goo.ne.jp/leaf/jn2/154743/m0u/%E3%81%A8%E3%81%84%E3%81%86/)),
e.g.:

> 今日という今日  
>  "today of all days"
