FEATURES AND BENEFITS

• TallWall® is the ideal panel for wall sheathing. Whether you build 8’, 9’, or 10’ walls Norbord has the right size-sheathing panel for you.
• Use TallWall® panels to overlap the floor joists to increase your wall strength by up to 38% e.g. 4x10’ TallWall® on 9’ walls has 38% greater displacement compared to using 4x8 panels.
• The extra length means walls go up with less labor, material, waste, handling and shorter build times.

END USES

• TallWall® is engineered specifically to be used for wall applications and is not to be used for roof or floor sheathing.

HANDLING AND STORAGE

• Norbord OSB panels should be stored flat, indoors or under cover and protected from the elements.
• When stacked, panels with supports banded to the units need to have the supports aligned.
• On panels too large to have the supports banded to the unit, full width blocking needs to be placed 6" from each end and at 24" intervals over the length of the unit.
• If stacked, this blocking also needs to be aligned.
• If stored outdoors, keep panels off the ground and on a flat base. Cover loosely to allow air circulation at the sides.
• OSB should not be exposed to the weather or moisture on a continuous basis. However, exposure 1/exterior bond rating indicates that unprotected exposure during normal construction periods will not adversely affect the structural properties.
• Panels should be handled and stored with care to avoid damage and should be used on a first-in, first-out basis.

INSTALLATION

1. All panels should be continuous over two or more spans.
2. All panels should be spaced 1/8" apart along all edges.
3. Provide 3/4" expansion joints for every continuous section of panels exceeding 80 feet in length.
4. Nails should penetrate structural members a minimum of 1".
5. Sheathing paper is not generally required over OSB unless stucco, non-wood siding or, in some cases, brick veneer, is used for the exterior finish. (Consult the applicable building code.)
6. Nail spacing** should be 6" on center along panel edges and 12" on center into intermediate supports.
7. Building codes require an impermeable moisture barrier on top of the ground cover in all crawl spaces.
8. Prior to application, acclimatization of panels to surroundings for at least 24 hours is recommended.
9. When applicable, span ratings, durability and mill identification is included in the grade stamp applied to every panel.

*Up to 38% stronger as tested by an independent lab, with one-piece TallWall panels overlapping the floor framing and covering the top plate.

**Consult your local building codes for local requirements and specifications
