Frame assembly

A window frame assembly system comprising:

• a head jamb having a first length defined by a first end and a second end, the head jamb comprising a first cross-sectional profile, the first cross-sectional profile including:
• a first opening comprising a first enclosed interior passage proximate an exterior edge of the first cross-sectional profile and configured to receive a corner key arm having a first complementary profile;
• a second opening defined in part by a first planar section configured to lie adjacent to an inward facing surface of a window opening and by first and second perpendicular segments contiguous with and perpendicular to the first planar section, the second opening comprising a second enclosed interior passage proximate an interior edge of the first cross-sectional profile and configured to receive a corner key arm having a second complementary profile, the interior edge disposed opposite the first cross-sectional profile from the exterior edge along a depth of the window frame assembly;
• a partially enclosed fin groove defined in part by the first perpendicular segment such that the fin groove is adjacent to the second opening along the depth, the fin groove opening outward relative to the window frame assembly to securably receive a nailing fin of the window opening;
• and
• an interior facing channel defined in part by the second perpendicular segment and the first planar section;
• a plurality of side jambs, each side jamb having a second length defined by a top end and a bottom end, each side jamb comprising the first cross-sectional profile;
• a sill jamb having a first end and a second end defining a length equal to the first length, the sill jamb comprising a second cross-sectional profile;
• and
• a plurality of corner keys, each corner key comprising a first arm and a second arm orthogonal to the first arm, the plurality of corner keys comprising:
• at least one first head corner key having the first and second arms each configured to seat within the first opening of the first cross-sectional profile to orthogonally couple the head jamb to one of the plurality of side jambs;
• and
• at least one second head corner key having the first and second arms each configured to seat within the second opening of the first cross-sectional profile to orthogonally couple the head jamb to one of the plurality of side jambs.

A window frame assembly comprising:

• a head jamb having a first end and a second end;
• a plurality of side jambs, each side jamb having a top end and a bottom end, each top end coupled, by a first head corner key and a second head corner key, to the first end or the second end of the head jamb;
• and
• a sill jamb having a first end and a second end, each of the first end and the second end of the sill jamb being coupled to the bottom end of one of the plurality of side jambs by a sill corner key;
• wherein each of the head jamb and the side jambs comprises an elongate member having a first cross-sectional profile, the first cross-sectional profile including:
• a first opening comprising a first enclosed interior passage proximate an exterior edge of the first cross-sectional profile and configured to receive a corner key arm having a first complementary profile;
• a second opening defined in part by a first planar section configured to lie adjacent to an inward facing surface of a window opening and by first and second perpendicular segments contiguous with and perpendicular to the first section, the second opening comprising a second enclosed interior passage proximate an interior edge of the first cross-sectional profile and configured to receive a corner key arm having a second complementary profile, the interior edge disposed opposite the first cross-sectional profile from the exterior edge along a depth of the window frame assembly;
• a partially enclosed fin groove defined in part by the first perpendicular segment such that the fin groove is adjacent to the second opening along the depth, the fin groove opening outward relative to the window frame assembly to securably receive a nailing fin of the window opening;
• and
• an interior facing channel defined in part by the second perpendicular segment and the first planar section;
• wherein the sill jamb comprises an elongate member having a second profile different from the first profile;
• and
• wherein each first head corner key comprises two arms configured to seat within the first opening of the first cross-sectional profile, and each second head corner key comprises two arms configured to seat within the second opening of the first cross-sectional profile.
