Claim 25:
26. A corner joint comprising:
a first frame member defining a first longitudinal frame member axis;
a second frame member defining a second longitudinal frame member axis; and
a corner bracket coupling the first frame member and the second frame member to one another, such that the first frame member longitudinal axis and the second frame member longitudinal axis are transverse with respect to one another, the corner bracket comprising:
a structural portion comprising at least one first material;
a sealing portion comprising at least one second material different than the at least one first material;
a first receiver defining a first longitudinal axis and receiving an end of the first frame member, the first receiver comprising:
a first retainer portion coupled to the end of the first frame member; and
a first sealing interface configured to provide a substantially fluid-resistant seal between a portion of the end of the first frame member and the first receiver;

a second receiver defining a second longitudinal axis transverse to the first longitudinal axis of the first receiver and configured to receive an end of the second frame member, the second receiver comprising:
a second retainer portion coupled to the end of the second frame member; and
a second sealing interface configured to provide a substantially fluid-resistant seal between a portion of the end of the second frame member and the second receiver,

wherein the first retainer portion comprises:
a first attachment portion presenting an abutment surface facing a direction substantially orthogonal to the first longitudinal axis of the first receiver; and
one or more holes extending through the first attachment portion and configured to receive fasteners configured to secure the end of the first frame member to the first retainer portion.
