Abstract
A simple, relatively low cost system for sealing an ordinary roller shade with respect to the window frame sides, top and bottom is provided. The roller shade seal system essentially comprises a pair of edge seal assemblies in the form of elongate mounting strip members adapted to be permanently mounted to opposite vertical faces of the window frame trim, and a pair of sealing strip members in the form of elongate, generally U-shaped channels adapted to sealably engage the latter edges of the shade, releasably mounted to an associated mounting strip. The window shade sealing system is completed by a shade bottom edge seal comprising a rigid bottom strip reinforcing member, a sill sealing strip and a shade top sealing member.
