Abstract: A hybrid window frame assembly includes a primary window frame formed of a first material connected to a cladding frame formed of a second material. The cladding frame includes a peripheral channel defining a recess that receives a peripheral bead of the window frame to connect the cladding frame to the window frame. The hybrid window frame further includes injection block cutouts at each corner. Each injection block cutout exposes at least a portion of respective inner sidewalls of the channel and bead. The hybrid window frame assembly further includes injection blocks inserted in each injection block cutout. Each injection block includes at least one injection hole accessible from an exterior of the hybrid window frame assembly. The hybrid window frame assembly further includes sealant injected through the at least one injection hole of each injection block to seal respective corners of the window frame and cladding frame together.
