ABSTRACT:
A prefabricated slider window system includes a main frame made from extruded thermoplastic members. Windows are mounted in the main frame for horizontal sliding movement. The main frame includes a bottom frame portion having channels for guiding the bottom sides of the windows, and a top frame portion having channels for guiding the top sides of the windows. The channels are deeper in the top frame portion than in the bottom frame portion to permit the windows to be raised out of the channels in the bottom frame portion. The raised windows can then be removed from the main frame so that the outdoor sides of the windows can be cleaned.
