Increased incidence of strong weather systems and the tragedies that follow high wind events have encouraged engineers and designers to rethink the way we build to improve wall strength. Stronger walls will keep home occupants safer during weather events and will increase the lifespan of the home. One of the problems is that the roof, wall and flooring systems are installed as separate entities. Connecting the OSB wall sheathing and the flooring system can create a continuous load path which can improve wall strength by up to 38%.
Innovative manufacturers like Norbord that think outside the box have flipped the structural sheathing panels for vertical installation and increased their height. Longer wall sheathing like TallWall enables an overlap at the joists which eliminates hinge points to increase wall strength. Longer sheathing also reduces the number of seams which improves energy efficiency and makes for a stronger, smoother, flatter wall.
