ABSTRACT:
The window frame is adapted to receive at least one sash and has metal portions on an outdoor face thermally insulated from metal portions on an indoor face to thereby provide a thermal break. At least in part, the thermal break is attained by way of a thermal barrier strip having spaced parallel zones of contact with juxtaposed walls of the metal portions.
