STORAGE/INSTALLATION ROSEBURG BRECKENRIDGE CEDAR PLYWOOD
Roseburg Breckenridge Cedar Plywood should be kept inside, especially if it will not be used instantly. When it is necessary to store the siding outdoors, the components should be kept off of the floor and covered loosely with protective stuff. The structure to which the siding has been implemented should be well vented and dry before siding application. New construction ought to be left open to allow for venting of extra construction moisture.
Siding panels can be installed vertically, directly over wall framing (studs or 26’s), provided the on-center stud spacing doesn’t exceed the span rating given on the plank rear stamp. All panel ends and edges should occur over framing. Roseburg urges a 1/16″ minimal gap between panel edges and 1/8″ gap between panel endings. Panel spacing is important to allow for any potential panel growth brought on by moisture absorption. Horizontal joints in multi-story buildings should allow for framing shrinkage. Use only corrosion resistant nails. Utilize 6D box, casing, or siding nails for panels 1/2″ thickness or less (a minimum of 5/8″ in the panel edge), and 8D for greater depth (minimum of 3/8″ in the panel edge). When applied over plywood or wood sheathing, the nails should permeate 1″ into the studs, except that when Gypsum sheathing can be used the claws should permeate the framing 1-1/2″ minimal. The nailing sequence can also be a factor in maintaining a uniformly flat look to the wall. Position the siding panel, maintaining the advised edge spacing, and gently tack at each corner. Install the first row of nails beside the previous panel from top to bottom.
Eliminate the tacking nails. Then nail the row in the first intermediate stud. Continue by nailing in the 2nd intermediate stud, and eventually at the edge opposite the previous panel. Complete the setup by adjusting to the top and bottom plates. The nail heads should be cozy or flush with the panel surface.
Let at least 6″ between the bottom edge of the siding and the final grade or flat surfaces. Building paper is not required for vertical setup, unless defined by local building code. Apply a vapor barrier to the warm side of this wall.
For the best performance, Roseburg urges a solid-color acrylic-latex complete be applied to the siding inside 30 days of setup.
