Installation

Norbord structural panels are to be installed according to the APA’s (The Engineered Wood Association) Construction Guide E30 and the appropriate building code. Below are some key installation points.

1. All panels should be spaced 1/8″ apart along all edges.
2. All panels should be continuous over two or more spans.
3. Installing TallWall panels to overlap the joist area and the top plates significantly increases wall Capacity, Stiffness and Displacement*. Use 4×9’s with 8’ walls and 4×10’s with 9’ walls.
4. Provide 3/4″ expansion joints for every continuous section of panels exceeding 80 feet in length.
5. Fastener spacing**
6. Prior to application, acclimatization of panels to surroundings for at least 24 hours is recommended.
7. When applicable, span ratings, durability and mill identification is included in the grade stamp applied to every panel.

**Consult your local building codes for local requirements and specifications and the APA Construction Guide E30

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