SHEATHING SPECIFICATIONS
THIS MODEL HAS BEEN DESIGNED TO RESIST LATERAL
FORCES RESULTING FROM:
115 MPH WIND IN 2020 InRC MAP
(115 MPH WIND SPEED IN ASCE 7-16
WIND MAP, PER IRC R301.2.1.1)
EXP. B, RISK CAT. 2 & SEISMIC CAT. A/B.
THE DESIGN WAS COMPLETED PER 2018 IBC
(SECTION 1609) & ASCE 7-16, AS PERMITTED BY
R301.1.3 OF THE 2020 InRC, OR THE SIMPLIFIED

WITH THE 2020 InRC IF THE PARAMETERS OF
SECTION R602.12 COMPLY. ACCORDINGLY, THIS
MODEL, AS DOCUMENTED AND DETAILED
HEREWITHIN, IS ADEQUATE TO RESIST THE CODE
REQUIRED LATERAL FORCES.
SEE CONNECTION SPECIFICATIONS CHART FOR
STANDARD SHEAR TRANSFER DETAILING. IF
ADDITIONAL CAPACITY IS REQUIRED BY DESIGN, IT
WILL BE SPECIFICALLY NOTED ON PLAN.
ALL STRUCTURAL PANELS ARE TO BE DIRECTLY
APPLIED TO STUD FRAMING.
