Braced Wall Panel Applications
- Wear gloves and eye protection.
- To mark board before cutting, drag the hook of a measuring tape along the printed side of the board while holding the other end of the tape at the desired measurement. Or use a straight edge to mark a cutting line.
- Set the board on a flat, sturdy surface for ease and safety in cutting. Follow the cutting line with a circular saw.
- With the BLUEâ„¢, non-reflective, resilient exterior surface facing the exterior, install the board vertically with long joints in contact with one another and bearing directly on the framing members (Figure 1).
- Secure board using recommended fasteners and a pneumatic nail/staple gun. Space fasteners as indicated in Table 1.
- Tape fastened board joints with WEATHERMATEâ„¢ Construction Tape (2-7/8" wide) (Figure 2). If a WEATHERMATEâ„¢ housewrap product or equivalent will be installed on top of sheathing, follow housewrap installation instructions.
- Repeat steps 2-5 to install non-structural insulation from Dow, except follow fastening pattern as indicated in Table 2.
