Rain screen framing system
The present invention provides a universal framing system for securing cladding to the interior or exterior of a structure. The framing system comprises hat channels, face plates, Z-channels, inside corner trims, outside corner trims, and window trims. The components of the framing system are secured to a wall of a structure, then panels of cladding are secured to the components.

the first panel adjacent to the second panel at a position over the face plate to provide a solid backing at the adjacency of the first and second panels.
7. The sub-framing wall system of claim 1 , further comprising:
an inside corner trim comprising:
a first wall;
a second wall perpendicular to the first wall to form an L-channel;
a first flange coupled to the first wall, the first flange parallel to, and offset from, the first wall;
a second flange coupled to the second wall, the second flange parallel to, and offset from, the second wall; and,
the first and second flanges being offset outwardly from the L-channel.
8. The sub-framing wall system of claim 1 , further comprising:
an exterior corner trim comprising:
a first wall;
a second wall perpendicular to the first wall to form an L-channel;
a first flange coupled to the first wall, the first flange parallel to, and offset from, the first wall;
a second flange coupled to the second wall, the second flange parallel to, and offset from, the second wall; and,
the first and second flanges being offset inwardly from the L-channel.
9. The sub-framing wall system of claim 1 , further comprising:
a Z-channel, comprising:
a central wall having a first edge and an opposite second edge;
a first flange extending perpendicularly outward from the first edge of the central wall; and,
a second flange extending perpendicularly outward from the second edge of the central wall, in a direction opposite to that of the first flange.
10. The sub-framing wall system of claim 1 further comprising:
a window trim comprising:
an elongated body having a substantially rectangular cross section;
a wall-facing surface and an opposite exterior-facing surface;
a frame-facing surface perpendicular to the wall-facing and exterior-facing surfaces;
a cladding-facing surface opposite the frame-facing surface; and
a pair of legs extending from the wall-facing surface to define a channel;
a longitudinal cavity formed in the body; and,
a flange extending outward from the cladding-facing surface of the body, parallel to, and offset from the wall-facing and exterior-facing surfaces.
11. The sub-framing wall system of claim 10 , wherein the window trim further comprising:
the longitudinal cavity having at least one fastener boss.
12. The sub-framing wall system of claim 10 , wherein the window trim further comprising:
the longitudinal cavity having at least two fastener bosses.
13. The sub-framing wall system of claim 10 , wherein the longitudinal cavity of the window trim further comprising:
a rectangular portion;
a circular portion on opposite ends of the rectangular portion; and,
a beveled portion connecting each of the circular portions with the opposite ends of the rectangular portion; and,
the circular portions receivable of a fastener.
14. The sub-framing wall system of claim 10 , wherein the window trim further comprising:
perforations formed in the flange.
15. The sub-framing wall system of claim 10 , wherein the window trim further comprising:
four lengths of the window trim are assembled in perpendicular relationship to form a trim-frame assembly over a window frame.
16. The sub-framing wall system of claim 1 further comprising:
the strike ridges of the face plate engaging the latches of the hat channel to secure the face plate in the cap seats of the hat channel.
17. The sub-framing wall system of claim 1 , wherein the face plate further comprising:
a relief radius located between each of the side legs and the body.
