What is special about Windstorm and why does it work?
Norbord’s large continuous press mills can manufacture panels engineered to match wall heights whether slab on grade or raised floor. Windstorm panels are engineered to allow the use of the continuous sheathing methods allowed by building codes. High wind building codes such as SSTD 10-99 and the WFCM call for structural panels to cover from the top of the top plate, to the bottom of the bottom plate, or mid band, to meet combined uplift and shear values. Therefore 8′ walls on a slab require 97 1/8″ panels and 9′ walls need 109 1/8″ panel, right up to 145 1/8″ without joints. Windstorm panels are available in the right sizes and combined with a design professional’s fastener schedule provide the continuous load path required by the codes.
