ABSTRACT:
A thermal-break window of extruded frame members interconnected to form a substantially rectangular frame for encasing a glass panel in which each of the frame members is formed with a channel along its axial length. This channel contains a material of low thermal conductivity hardened in situ and with a strip of the extruded material along the channel being removed, effectively separating thereby each of the extruded frame members into two sections along their entire lengths, representing exterior and interior sections, that remain joined only by the material of low thermal conductivity. Consequently, the exterior frame sections are and remain thermally insulated from the interior frame sections. Furthermore, certain of the extruded frame members are designed to snap-fit to one another, providing for ease and simplicity in assembly.
