Technical Specifications

Installation Requirements
WindBrace
®
OSB Wall Sheathing must be installed with the long dimension
parallel to framing members. The smooth side of the panel should face the exterior
of the structure. Attach the top of the WindBrace
®
to the top of the framing top
plate and the bottom of the WindBrace® to the bottom sill plate.
Panel acclimation: Panels require 24 hours to acclimate to surrounding
environmental conditions prior to installation.
Panel edge spacing: 1/8” minimum spacing is required along all edges, although
extended-length panels require up to 1/4”.
Nailing pattern: 6-inches on center on panel edges and 12-inches on center
in the intermediate portion of the panel. Local building codes and/or engineer
specication may require a tighter nailing pattern than previously stated. If so,
to minimize panel buckling, nail according to RoyOMartin’s nailing pattern rst,
allow 72 hours to acclimate, then nail to the tighter nailing pattern.
Application
WindBrace
®
oversize OSB panels are a full 1 1/8 in. taller than traditional OSB
panels, enabling builders to tie the top plate to the bottom plate with a single
sill-to-plate structural panel. Engineered for greater strength and less deection,
WindBrace
®
reduces labor and material costs by eliminating the need to install
metal connectors, threaded bolts, and blocking and ller strips.
Storage & Handling
Like any wood product, WindBrace
®
OSB Wall Sheathing should be stored to
avoid excessive moisture pick-up. Store in a warehouse under cover of a roof or
on concrete oors 3 inches off the ground. When stored outdoors, cover panels
loosely with a protective material. Clear covering is not recommended. If plastic
tarps are used, anchor them on top of the unit, but keep them away from the sides
and bottom to ensure good air circulation and ventilation around the panels. Cut
the banding on the unit to prevent edge damage. Allow 24 hours for panels to
acclimate to the surrounding external weather conditions prior to installation.
WindBrace
®
OSB Wall Sheathing panels are intended for protected construction
applications. If subjected to rain or standing water during normal construction, the
panel edges may swell and mild surface roughening may occur. If these conditions
are encountered, touch-sand panels where necessary after drying is complete.

panels are engineered to meet or exceed United States Department
of Commerce PS-2 product standards including ICC ESR-2586 for use in load
bearing wall sheathing high wind load zones. WindBrace
®
panels are specically
designed to attach the bottom plate to the top of the top plate, to meet the more
stringent wind board criteria. All panels are stamped with a unique APA stamp
with mill number 511.
