Ceiling Fan. Wednesday , December 13th , 2017 - 07:18:43 AM
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.)
On days that are cold (or hot, in summertime), the larger spaces created by vaulted ceilings require more energy to heat (or cool down). This decrease in energy efficiency can be considered a waste and unnecessarily expensive, because no one really “uses” that extra air up there.
This ceiling fan is perfect for the kids room because it looks just like a pinwheel and kids love pinwheels. When you start it and it spins the visual resemblance is perfect. Each blade of the fan is coloured differently and the kaleidoscopic pattern of colors stimulates kids' imagination. What is even more interesting about the fan is the colour choice. There are six blades and three of them are coloured in primary colours: red, yellow and blue. In between these primary colours the blades are coloured with the result of the mix of colours. For example green is between yellow and blue and so on. You can purchase the item manufactured by Quorum from Lumens for $238.
