ABSTRACT:
A sliding window is disclosed for use in homes, apartments or businesses. A frame is provided having a sill, header, jambs and a mullion all of which can be produced from extruded aluminum sections assembled into a rigid frame. Two framed window panels are contained in the rigid frame, one panel has a fixed location the other panel slides relative to the rigid frame. Each panel is carried in a separate groove having a vinyl liner. The grooves are separated by a spacer. The sliding panel rides on rollers in its respective groove and is opened, closed and locked by a handle. The fixed panel also rides on rollers and is fixed in its location by the removable mullion which securely locks the frame header and sill together. The mullion has tabs extends through one of two sets of slots in the header and sill where it is secured by a screw. The fixed panel may be located on the left or right hand side of the frame as desired. One set of slots is used by the mullion to lock the fixed panel in the desired location. Other novel features decrease the air infiltration, sound transmission, ease servicing of the roller assembly, and reinforce window security.
