Casement windows have a blend of contemporary and modern look built to provide maximum ventilation when opened and to prevent air infiltration when closed. They are designed with a side hinge to operate horizontally to open outward to the right or to the left. They are designed to open up to 90 degrees in order to assure easy cleaning and efficient air circulation. Not only do they have a solid structural frame that increases overall strength but they are also armed with a multi-point locking system that adds adjustment and security.
