ABSTRACT:
A method and apparatus for a metal frame for windows, doors and the like which provides a thermal break between the interior and exterior surfaces of the frame. The frame comprises an interior frame portion which is coupled to an exterior frame portion through an insulated joint. Separating and insulating the interior frame portion from the exterior frame portion is a woven or matted fabric. Keeping the fabric in place and mechanically bonding the interior frame portion to the exterior frame portion is a resin which saturates the fabric between the two frame portions and is cured. The solid resin thereby obtained maintains the spaced distance of the two formed portions while securing them together to form a rigid unitary frame which is thermally non-conductive.
