Domes were the first popular vaulted ceiling option – imagine a hollow sphere cut in half. Built at times before history was even history, domes have been constructed out of mud, stone, wood, brick, concrete, metal, glass, and even plastic. The barrel vault (aka wagon vault and tunnel vault) stemmed from the dome and is the simplest kind of vault – a semicircle stretched into a continuous arch. Next came the groin vault, which is where two barrel vaults cross one another and create a true ellipse intersection known as a groin.
The rib vault came about in medieval times, where builders set up diagonal ribs first and then built the vaulted ceilings on these. And the fan vault is a fancy, filled-out version of the rib vault, in which the lower portion of the arch forms the smallest part of an open fan and the upper part extends outward like an open fan. (Check out Encyclopedia Britannica for more information on vaulted ceilings.)
The greatest thing about ceiling fans is that they have a double purpose, serving as both a functional piece and a decorative element for the room they're in. But, while this is all wonderful and practical, it also makes choosing a ceiling fan that much more difficult.
