Abstract
Abstract A clad window wherein a wooden window frame assembly has each of its frame members covered with metal cladding, with each of the cladding members having at its ends beveled edges which join with the beveled edge of another cladding member to form a mitered corner. The beveled edges of each cladding member have a portion of the edge turned back to provide a flange and a cladding retaining clip releaseably engages the flanges of each beveled edge, at each of the mitered corners, to releaseably and sealingly secure the cladding to the window frame assembly. When repair work is needed retaining clips are removed, the window frame may be disassembled, the repair work accomplished, cladding slipped back into position and the retaining clips again attached for releaseable and sealing securement.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
160 words
A clad window comprising, a pair of spaced apart, substantially parallel stiles, a pair of spaced apart, substantially parallel rails which join said stiles to form a window frame assembly, and metal cladding members which cover at least the front face portion of each of said stiles and rails, each of said cladding members being mitered at their opposite ends, edges which join mitered edges of other cladding members to form a mitered corner juncture, said mitered edges having a portion of each turned back to provide a flange, and a cladding retaining clip which releaseably, and slidably, engages the flanges of said mitered edges at each of said mitered corners to releaseably secure said cladding to said stiles and rails and to sealingly cover said mitered corner juncture making it substantially weather impervious, each of said cladding members when not retained by said retaining clip being capable of independent sliding movement along the rail or stile that it covers.
