A ''fixed window'' is a window that cannot be opened,<ref>{{Cite book|url=https://books.google.com/books?id=CVTjAQAAQBAJ&q=Fixed+window+is+window+that+cannot+open&pg=PA83|title=Kitchen & Bath Residential Construction and Systems|author=NKBA (National Kitchen and Bath Association)|date=2013-10-29|publisher=John Wiley & Sons|isbn=978-1-118-71104-0|language=en}}</ref> whose function is limited to allowing light to enter (unlike an unfixed window, which can open and close). [[Clerestory]] windows in [[church architecture]] are often fixed. Transom windows may be fixed or operable. This type of window is used in situations where light or vision alone is needed as no ventilation is possible in such windows without the use of [[trickle vent]]s or overglass vents.
