Overview
Sheathing materials forming the exterior envelope assembly of a building with light-frame wood or steel walls, must be specified to resist to out-of-plane wind loads (positive and negative/suction pressures). Building codes specify these requirements for various sheathing materials. Wind resistance of FPIS is not required where placed under or over a separate sheathing material capable of resisting wind loads.
For specification of FPIS where wind resistance is required, refer to:
- Refer to FPIS manufacturer code-compliance data
- FS100 Standard
