In architecture, a splayed opening is a wall opening that is narrower on one side of the wall and wider on another. When used for a splayed window, it allows more light to enter the room. In fortifications, a splayed opening is used to broaden the arc of fire (cf. embrasure, loophole).[1]
Splayed arch
[edit]A splayed arch (also sluing arch[2]) is an arch where the springings are not parallel ("splayed"), causing an opening on the exterior side of an arch to be different (usually wider) than the interior one. The intrados of a splayed arch is not generally cylindrical as it is for typical (round) arch, but has a conical shape.[3][4]
Double-splayed window
[edit]
Double-splayed windows, widening towards both wall faces, with the narrowest part in the middle of a wall, were common in the Anglo-Saxon architecture.[citation needed]
