Damaged?: Unknown


Stationary-blade adjustable-width louvers expand or contract in width to fit a variety of openings. They feature a flanged frame and blades that nest inside each other and slide. This allows the louver to adjust its width to fit various openings in an exterior wall. They provide water intrusion protection but do not have a drainage system to deal with rain that falls onto the blades. Any rainfall that hits them will be carried downwards by gravity.
