A well designed awning window will seal tightly when it is closed and locked minimizing air leakage. Awning windows are hinged from the top side of the sash and project outward. Multipoint locks usually secure the sash at both the left and right side of the frame. Manual or power operation may be used to open and close the sash. AmesburyTruth provides a variety of extrusions and weather-strip solutions to optimize your awning window design.
