Casement windows by EZ Window Solutions are one of those less known window types but offer some amazing benefits we think you should know about. What exactly are casement windows? If you don't already know, casement windows open outward with a crank handle on a hinge compared to other windows that open vertically or horizontally. Casements don't have a center rail making them a great choice for unobstructed sight lines, a.ka. a much better view.
