Frame system

Abstract

A peripheral frame is provided suitable for use as the frame or sash for a glazed window or patio door unit, or for use as an outer frame or semi-peripheral frame to contain window or door units. The frame is of U-form section, having a pair of substantially parallel legs and an interconnecting end portion forming an outwardly facing bight. The outer surface of the section end portion forms the inner periphery of the frame and the leg portions of the section form the faces of the frame, and, provide an outer peripheral access to the interior of the frame section. The frame can be provided with various concealed inserts appropriate to its function located in the interior of the section, such as wood, metal or other inserts. Such inserts may comprise reinforcement frames and insulation material, including foamed in-situ insulation and reinforcement; and attachment and/or suspension hardware for components supported by the frame. The frame inner periphery can be shaped to include one or more peripherally extending door jambs or glazing stops, and may include provision to secure snap-in glazing stop so as to facilitate installation of glazing units, either insulated (eg. gas filled) or plain. Peripheral frame cover plate portions can be removably or permanently secured in enclosing relation with the frame section.
