ABSTRACT:
In a window assembly having a pair of sashes mounted within a supporting frame for relative horizontal movement, each sash is integrally provided with a pair of opposed rims defining an outwardly open channel along each of its top and bottom horizontal members and along one of its side vertical members which is to be held against one of the jambs of the supporting frame upon closure of the sash. When the sashes are moved to their closed positions, a plurality of vertical rolls mounted in selected positions inside the channels of each sash ride on respective raised roll seats formed on stationary flanges intruding into the respective channels from the supporting frame. Upon resulting lateral displacement of the sashes relative to the supporting frame, sealing strips also arranged internally of the channels become pressed against the flanges.
