Ultra Sheathing

INSTALLATION GUIDELINES

PLYGOOD Ultra can be installed vertically on exterior walls

and horizontally across gable end walls using the following

installation steps:

Exterior Walls—Sheathing Installed

Vertically

Start at one end of the home and begin by aligning the bottom

edge of the PLYGOOD Ultra sheet with the bottom edge of the sill

plate, while also making sure that the vertical edge of the sheet is

aligned with the corner stud.

Attach PLYGOOD Ultra using staples (1" x 1

x 16 Ga. or

x 1

x 16 Ga.) or 1

plastic cap nails (spaced 12" o. c.),

starting at the bottom edge of the wall. Staples should be spaced

4-5 inches apart for 1" crown staples and 3 inches apart for

crown staples. PLYGOOD Ultra is printed with staple lines that are

intended to guide the installer in locating studs.

Continue installing subsequent courses of PLYGOOD Ultra by

butting vertical edges of adjacent sheets together and fastening

as described in Step 2.

Cut door and window openings and other necessary penetration

areas using a common utility knife, taking care to inform others

that there will be cutting in the area.

If fractures occur in PLYGOOD Ultra, they should be taped to

minimize the possibility of air infiltration.*

Install the siding and trim accessories in accordance with the

manufacturer’s installation

instructions.

Exterior Walls—

Sheathing Installed

Horizontally At The

Attic Gable End Walls

Begin by taking measurements of the area to be covered with

PLYGOOD Ultra and cut the sheets to the correct dimensions. A

chalk line can be used to achieve a straight edge cut.

Align PLYGOOD Ultra horizontally so that the edge is butted up

against the top edges of the vertically installed sheets of

PLYGOOD Ultra on the exterior wall.

Attach PLYGOOD Ultra using staples (1" x 1

x 16 Ga. or

x 1

x 16 Ga.) or 1

plastic cap nails (spaced 12" o. c.),

starting at the bottom edge of the wall. Staples should be spaced

4-5 inches apart for 1" crown staples and 3 inches apart for

crown staples. PLYGOOD Ultra is printed with staple lines that are

intended to guide the installer in locating studs.

If fractures occur in PLYGOOD Ultra, they should be taped to

minimize the possibility of air infiltration.*
