One of the earliest forms of windows, the casement has been around for centuries. It features a sash that is hinged from the side on an outer frame and can open inwards or outwards, to the left or right, allowing maximum flow of air into the room. Extremely energy efficient when closed, this casement window comes in varied designs like side hung, top hung etc.
Casement Windows are common in modern day homes, especially widely used for its excellent sound proof efficiency for the house fascade openings.
