Patent ID: 8281532

Claim:
A three-dimensional edge cladding for an architectural opening, comprising: a) a forward facing portion having a substantially constant first profile along a longitudinal axis, and including; i) a first portion including an outboard nailing flange and an inboard nailing flange, the outboard and the inboard nailing flanges being spaced apart from each other on opposite sides of the longitudinal axis in a common first plane; ii) a second portion including an exterior stepped surface topography projecting generally forward and away from the first plane, the stepped surface topography including a plurality of substantially planar exterior wall segments that are generally parallel to the first plane; iii) a longitudinally extending channel flange disposed along substantially the entirety of the length of the forward facing portion, the channel flange being generally parallel to one of the substantially planar exterior wall segments and projecting from the second portion for defining a receiving channel that extends substantially the entirety of the length of the forward facing portion; b) a side facing portion having a substantially constant second profile and adapted to be received in the forward facing portion, the side facing portion including a first longitudinally extending wall surface segment having a first longitudinal free edge and a second longitudinally extending wall surface segment having a second longitudinal free edge, the first segment and the second segment being disposed generally orthogonally to each other and the second segment being in planar contact with a terminating edge of a wall frame portion to create a nailing surface that is perpendicular to the outboard nailing flange and inboard nailing flange; wherein the first longitudinally extending wall surface segment is disposed at least partially within the channel flange along substantially its entire length; wherein an open space is defined behind the exterior stepped topography and forward of the first plane; wherein the forward facing portion and the side facing portion have a substantially constant wall thickness less than about 5 mm throughout the entirety of their profiles; and wherein at least the forward facing portion includes a plurality of substantially continuous longitudinally disposed glass fibers in a thermoset polymeric matrix.
