Casement windows also have a large expanse of unobstructed glass. This allows natural light to filter through and eliminate the need for artificial lighting. The increased amount of natural light in a home can improve a person's mood and increase their productivity. Aside from their aesthetics, casement windows offer security benefits. Intruders cannot open a casement window without breaking the glass. Those attempting to rob a home can easily be discouraged by its security features.
