[[quoteright:350:[[Film/FridayThe13thPartVIIIJasonTakesManhattan http://static.tvtropes.org/pmwiki/pub/images/dangerous_windows.jpg]]]]

In the horror genre, windows are not the safest thing. They're mostly [[SoftGlass thin breakable glass]], often big enough to let monsters and crazed madmen use it as an improvised entrance and make for a nice spot to grab unsuspecting victims to their doom. SoftGlass trope seems to be in effect as such monsters or madmen are rarely harmed by breaking them with their bare hands. Barricading windows can be hard work if there are too many of them and more often than not whatever is trying to get through, will.

Compare SuperWindowJump, DestinationDefenestration and WindowPain, in which windows are used for for improvised entrances, deliveries and exits, rather than monsters using them.

* The final act in ''Film/{{Alien 3}}'' has a bait-and-chase plan to lure the xenomorph into a lead mould by having it chase the inmates, who then close doors behind them to corral it where they need it... until the xeno takes advantage of the glass windows set into the doors to smash through and pick off the unlucky prisoner. The next inmate to try this is understandably [[OhCrap rather nervous]].

%%* ''Film/{{Feast}}''
