Pieces that are components of a frame for a window having a threat side and a safe side include a base and a pressure plate that together form part of one of a sill section, a head section, and a jamb section of the window. The base and pressure plate are elongated in a longitudinal direction. The base has (1) an L-shaped cross-section at a near portion of the base to receive an end of a glazing unit from the threat side of the window, and (2) a first pocket formed in a far portion of the base and running in said longitudinal direction. The rear portion is closer to the threat side than the far portion. The pressure plate is to be assembled with the base so as to secure the glazing unit in the corner. Other embodiments are also described and claimed.

What is claimed is: 1. A window framing system, comprising: a plurality of pieces that are components of a frame for a window having a threat side and a safe side, wherein the pieces include a base and a pressure plate that together form part of one of a sill section, a head section, and a jamb section of the window; the base and pressure plate being elongated in a longitudinal direction, the base having (1) an L-shaped cross-section at a near portion of the base to receive an end of a glazing unit from the threat side of the window, the L-shaped cross-section having a first region that is substantially perpendicular to a second region, the first region being substantially parallel to a side, and not an edge, of the received glazing unit, (2) a first pocket formed in a far portion of the base and running in said longitudinal direction, the near portion being closer to the threat side than the far portion, and (3) a second pocket formed in a middle portion of the base, between the L-shaped section and said first pocket, the second pocket runs in said longitudinal direction and a first opening to the second pocket formed in a wall of the base and that runs the entire length of the second pocket, a plurality of holes opening into the second pocket and formed in a side of the base that is substantially perpendicular to the first region of the L-shaped cross-section, and a plurality of leveling bolts to be inserted through the plurality of holes, respectively, the pressure plate to be assembled with the base so as to secure the glazing unit in a corner; a base angle piece that is L-shaped with first and second perpendicular segments, the first segment being shaped to mate with and slide into the first pocket, the second segment having a plurality of holes spaced in said longitudinal direction; and a plurality of fasteners to anchor the frame through the plurality of holes to a building support structure. 2. The window framing system of claim 1 further comprising a shear block, wherein the first pocket is shaped to mate with the shear block and allows the shear block to slide into the first pocket in the longitudinal direction and be locked in a transverse direction. 3. The window framing system of claim 2 further comprising another shear block, wherein the second pocket is shaped to receive said another shear block and allows said another shear block to slide into the second pocket in the longitudinal direction and be locked in a transverse direction. 4. The window framing system of claim 3 wherein said second pocket and said another shear block run substantially the entire length of the base. 5. The window framing system of claim 2 wherein the shear block has a first plurality of holes that are aligned with a second plurality of holes in the base, the system further comprising a plurality of fasteners to be inserted through the first and second plurality of holes. 6. The window framing system of claim 1 wherein the base has a second opening to the first pocket that runs the entire length of the first pocket in the longitudinal direction. 7. The window framing system of claim 6 further comprising a cover sized to fit over the base and having a clip, wherein the base further comprises a finger formed integrally with the base as part of a single extruded piece of metal, to receive the clip. 8. The window framing system of claim 7 wherein the clip is a PVC clip to thermally insulate the cover and the base. 9. The window framing system of claim 1 further comprising a plurality of fasteners, and a first plurality of holes spaced in the longitudinal direction and being formed facing the threat side in the near portion of the base, the first plurality holes to receive the plurality of fasteners for securing the glazing unit. 10. The system of claim 9 wherein the pressure plate has a pair of indentations on opposite ends running longitudinally, to receive via snap fit a cover cap that hides the plurality of fasteners. 11. The system of claim 1 wherein the pieces are packaged to be shipped to a job site, so as to assemble the pieces to build the frame at the job site. 12. A window framing system, comprising: a plurality of pieces that are components of a frame for a window having a threat side and a safe side, wherein the pieces include a base and a pressure plate that together form part of one of a sill section, a head section, and a jamb section of the window; the base and pressure plate being elongated in a longitudinal direction, the base having (1) a forward facing L-shaped cross-section at a near portion of the base to receive an end of a glazing unit, the L-shaped cross-section having a corner above which the end of the glazing unit is to be supported, the L-shaped cross-section having a first region that is substantially perpendicular to a second region, the first region being substantially parallel to a side, and not an edge, of the received glazing unit, (2) a first pocket formed in a far portion of the base that extends backward from below the corner, and running in said longitudinal direction, the near portion being closer to the threat side than the far portion, (3) a second pocket formed in a middle portion of the base, between the L-shaped section and said first pocket, the second pocket runs in said longitudinal direction, (4) a first opening to the first pocket that runs the entire length of the first pocket in the longitudinal direction, (5) a second opening to the second pocket formed in a wall of the base extending from the corner of the L-shaped cross-section and that runs the entire length of the second pocket, and (6) a plurality of holes opening into the second pocket and formed in a section of the base that is (1) substantially perpendicular to the first region of the L-shaped cross-section and (2) below the corner of the L-shaped cross-section, the pressure plate to be assembled with the base so as to secure the glazing unit in the corner; and a cover sized to fit over the base and having a clip, wherein the base further comprises a finger formed integrally with the base as part of a single extruded piece of metal, to receive the clip. 13. The window framing system of claim 12 further comprising a shear block, wherein the first pocket is shaped to mate with the shear block and allows the shear block to slide into the first pocket in the longitudinal direction and be locked in a transverse direction. 14. The window framing system of claim 13 further comprising another shear block shaped to be received in said second pocket. 15. The window framing system of claim 14 wherein said second pocket and said another shear block run substantially the entire length of the base. 16. The window framing system of claim 13 wherein the shear block has a first plurality of holes that are aligned with a second plurality of holes in the base, the system further comprising a plurality of fasteners to be inserted through the first and second plurality of holes.
