Abstract:

A louver assembly has a plurality of louver blades and pivot shafts pivotally supported for adjustable movement between open and closed position in a frame which includes two opposed vertical side frame members. A jamb seal between each side frame member and the adjacent ends of the louver blades prevents air flow around the ends of the blades when the blades are closed. Each jamb seal includes a panel installed between a side frame member and the transverse louver blade ends facing that side frame member. Each panel includes a rigid but flexible, substantially flat, face portion adapted for flush contact with the blade ends when the blades are closed, and two outer and two inner elongated rigid supporting ribs integral with respect to the face portion and extending away from that side of the face portion opposite the blades. The edges of these ribs away from the face portion are provided from top to bottom with elastic sealing cushions. Each outer rib has a thin resilient air seal flipper being in sealing relation to its side frame member.
