Laying Panels

Before installing ooring, make sure the

framing underneath is level and not twisted.

Add shims or blocking as necessary to create

a smooth, at surface. Verify that the panel's

span rating meets or exceeds job require-

ments. Soft spots may occur if joist on-center

spacing exceeds panel span rating.

Panels should be installed with the 8' length

perpendicular to support members. When

laying out ooring, make certain that each

panel covers at least two spans and the

panel edges fall at the center of the support.

It may be necessary to trim some panels.

Make sure that the “This side down” stamp

is on the underside. Lay out rows of panels

so that end joints are offset by at least one

on-center spacing of the supports.

Gapping Panels

The panel industry recommends spacing

wood-based panels to allow for the expan-

sion that occurs when they are exposed to

moisture. When installing Weyerhaeuser

ooring, maintain a

⁄8" gap at panel ends

and edges. See Figure 1 on page 2.

Weyerhaeuser single-layer ooring is

manufactured with a self-gapping tongue-

and-groove (T&G) prole that automatically

gaps the edges as the oor is assembled.

See Figure 2. A 10d box nail can be used to

gauge the

⁄8" gap between panel ends.

Achieving optimum performance with Weyerhaeuser Edge

™

and Edge Gold

™

oriented strand board

(OSB) ooring and Weyerhaeuser sheathing depends heavily on correct installation and panel choice.

End-user complaints can be avoided by choosing an appropriate panel for the application, practicing

quality work, and installing Weyerhaeuser panels according to the techniques recommended here.

Minimize the chance for

accidents by installing panels

with the textured side up.

Safety

Always make safety a priority on the job site.

Follow all OSHA requirements for proper per-

sonal protection equipment (PPE), fall protec-

tion, forklift safety, and the use of equipment.

Adhere to Weyerhaeuser installation details,

including the installation of safety bracing on

unsheathed oors and roofs.

Consider that wet and/or steeply pitched

sheathing may be slippery. Make sure work-

ers have clean, slip-resistant roong shoes

and use all safety restraints required by

OSHA. To help minimize the chance for

accidents, install panels with the textured

(or screen) side up. Weyerhaeuser sheathing

is stamped “This side down” on the smooth

face to facilitate safe installation.

Storage

Like any wood product, wood-based panels

are at risk of fungal decay or rot if exposed

to repeated wetting or high-moisture

environments. Panels that are exposed to

such conditions may deteriorate, lose

strength, or support mold growth. For these

reasons, protection from these conditions

must be provided.

Keep all building materials dry and out of

standing water prior to installation.

Weyerhaeuser panels should be stored

at least 4" off the ground. During transit

and storage, make sure the panels are

not damaged.

Down Pore™ drainage groove with Edge Gold™ flooring These spacing recommendations may not be adequate for buildings over 80' in length or width. For these cases, consider installing temporary expansion joints and drilling drainage holes through floors to allow water to escape. Patch the holes later with wood dowels or non-shrink grout and backer plates. See Figure 3 for detail.

Poor contact can cause the nail to pop or become loose enough to squeak against the panel later on. Avoid this by having the operator stand on the flooring, or apply hand pressure, next to the area being fastened as the nail is driven. Most power-driven fasteners have adjustments for controlling pressure.

Narrow width panels Maintain 1 ⁄ 8" gap along all panel edges intersects with a joist. The optimal placement of non-load-bearing partitions that are parallel to the joists is directly over a joist. When it is necessary to nail directly to the flooring, clinch all nails while they are still accessible. Placing a bead of construction adhesive between the bottom plate and the flooring will enhance the connection and help prevent squeaks.

These spacing recommendations may not be adequate for buildings over 80' in length or width. See the recommendations for Expansion Joints for Roofs in Large Buildings. Nailing In general, begin nailing by starting a row 3⁄8" from one edge and work across the sheathing in rows.

Weyerhaeuser sheathing applied parallel or perpendicular to wall studs Stagger vertical joints Narrow Width Roof Sheathing Frequently when framing roofs, it is necessary to cut sheathing in narrow widths (24" wide or less) to accommodate ridges, hips, and valleys. In specialized construction, sheathing widths may even be 12" or less in width. However, every effort should be made to ensure that no panel is less than 24" wide even if more than one row of panels must be cut.

Gapping Panels The panel industry recommends spacing wood-based panels to allow for the expansion that occurs when they are exposed to excessive moisture. When installing sheathing, maintain a 1⁄8" gap at panel ends and edges. See Figure 8 on page 6. Use clips or blocking to support the panel edges. With full panels, use a 10d box nail to gauge the 1⁄8" gap between panels. Additionally, some panel clips are designed to serve as spacers between panels. See Figure 6 on page 5.
