1. The single bottom plate is fastened to the footing, slab or floor deck. Note the plates are separated to allow the first corner panel to pass the second corner panel. Type and quantity of fasteners depends on application and as determined by the engineer.
2. Flashings as shown are stapled to the plate before standing wall panels. A bead of PL-300 or acoustical sealant before applying the flashing insures a proper seal. Most fastening is completed using pneumatic tools. Where stucco will be used to finish the exterior flashing may not be required. Prior to placing wall panels a bead of PL-300 is applied to the inside corners in the bottom recess of the panels on both sides. This will adhere the panel to the plate.
3. Urethane foam is applied to the top of the bottom plate across the length of the next panel. This insures the vapor barrier is maintained.
4. The first corner panel is stood, aligned with a level and fastened on the inside and outside with 2” coated staples.
5. A vertical plate is fastened to the corner panel to attach the adjoining corner panel.
6. The vertical plate is fastened through the back inside of the panel with staples.
7. Then the stud is installed in the end of the panel and stapled in place.
8. The plate is then fastened to the panel with 4” screws.
9. The adjoining corner panel can then be attached using a bead of PL-300 each side and 2” coated staples inside and outside of the panel.
10. A bead of PL-300 is applied the face spline groove on each side of the end of the panel. A bead of urethane foam is placed from the top to the bottom of the EPS on the end of the panel. The 3’ X ½” MagBoard face splines are inserted in each side and then the dimensional stud is inserted between the splines. The next panel to be installed is prepped with glue the same way and dropped into place. The panel is then stapled along the joint. The staples penetrate the outer sheet of the panel, the face spline and the stud.
11. Window and door openings can be pre-prepped or cut out later.
12. The last panel on the wall section will be pre-cut on site to fit exactly. The last panel in each level will be pre-cut and slid down the corner from the top of the wall. Once that is complete the top of the panel at the corner can be cut down to allow for the installation of plates. Plates may also be installed as you install individual panels.
13. A 3 inch recess is cut in the top of the panel to allow for 2 - 1 ½” dimensional plates. The plates will be staggered as per typical framing methods. A bead of glue is run in both corners on top of the EPS and across the top of the studs. This ensures adhesion and maintains the vapor barrier at the top of the wall. On the upper story where trusses will be placed the poly vapor barrier is placed between the plates and draped over the side of the panel.
14. Floor joists or trusses are fastened into the top plate using typical methods. Where panels are used for basement foundation walls an 18 gauge light steel L-bracket is installed on top of the panel top plate.
