ABSTRACT:
A window frame is made of a plastic material which is secured together by utilization of corner key pieces at each of the four corners joining the header and the sill with a pair of jambs. The corner key pieces may be initially stapled or screwed to the frame members to create a stable unit prior to the permanent securement of the various members by means of ultra-sound welding.
