Awning Window
What is Awning Window?
Awning Window, A top-hinged window that swings outward from the bottom to provide ventilation while shedding rain.
Description
An awning window is a casement-style unit hinged at the head so the sash opens outward from the sill, forming a sloped panel that channels rainwater away while allowing airflow. Common frame materials include vinyl, aluminum, fiberglass, and wood-clad. Dual locking points and compression gaskets deliver tight weather seals, making awning windows popular in basements and modern façades. Glazing options include low-E coatings and argon gas for enhanced energy efficiency, while crank or friction hinge hardware allows for secure partial opening.
