Specifications

Lengths: 8’, 9’ & 10’

Widths: 4’, 5’

Thickness: 1/4’’- 1-1/4’’

Grade: CC, CD, CDC

Face: A layer of western

softwood (typically Douglas Fir)

veneer that has not been factory

sanded. It has limited pitch

pockets, open splits, and other

open characteristics but these do

not comprise the strength and

durability on the panel.

Core Substrate: Multi-

layers of thin wood (veneer)

in alternating wood grain

directions, which increases the

strength and stiffness of this

ﬁnished panel.

Back: Douglas Fir or White

Wood veneer that provides

excellent strength and durability.

Adhesive: NAUF exterior, fully

water resistant phenolic glue

Roseburg Plywood Sheathing delivers outstanding stiffness: strength and versatility, especially

in applications that require shear wall construction to comply with state and local build-

ing codes. Plywood structural sheathing is an excellent choice for wall and roof framing in

weather-protected applications.

• Adhesive is No Added Urea Formaldehyde (NAUF) exterior, fully water resistant phenolic

glue

• Cross-laminated veneer construction provides superior dimensional stability (resistance

to warping). It is also resistant to splitting, puncturing and impact damage

• Excellent nail, screw, and staple holding ability allows placement near panel edges

without splits

Storage in a warehouse or under roof is recommended prior to use. If stored outdoors, units

should be off the ground and covered loosely with some type of protective material.

• Nails directly over framing wall studs and roof joists

• Framing applications where state and/or local building codes require shear wall con-

struction for extra strength

• Sub-wall/roof foundation for home wrap vapor-barrier and the most common siding

material to be applied directly over it.

Can be cut, drilled, routed, glued, fastened and ﬁnished with ordinary tools. Always use

sharp, high-speed tools. Because of the cross-layer construction, nails, screws, and other

fasteners may be placed near the panel edge without splitting the panel.

Roseburg sheathing should be securely fastened with 6d nails on 1/4”, 3/8”, 1/2” panels

and with 8d nails on 5/8”, 3/4” and 1” panels. Space nails 6” o.c. around all panel edges

and 12” o.c. on intermediate supports. For sofﬁt applications, all panel edges should be sup-

ported. Nails should penetrate at least one inch into the substrate material. Leave 1/8” gap

between panel edges. Spiral or ring shank nails offer the best holding power. Screws and

bolts can also be used.
