End conditions for braced wall lines with continuous sheathing, Figure R602.10.7 in the IRC
Improper continuous load path design lacking bracing results in the failure of gable end walls under high wind conditions.
Right - A continuous load path connects the roof and wall framing to the foundation.
Right - Braced wall line spacing is correctly calculated for determining wall bracing in accordance with the IRC.
Step 1. Remove the existing wall cladding to prepare to retrofit an exterior wall.
Step 2. Install a continuous air and water control layer over the existing wall sheathing.
Step 4. Install insulating sheathing and vertical furring strips on the retrofitted exterior wall; seal around pipe or duct with urethane sealant.
Step 5. Install sheathing tape flashing over the duct or pipe and wood blocking on either side for later attachment of trim.
Step 6. Install vent hood trim block, metal cap flashing; seal top edge of flashing with sheathing tape.
Step 8. Attach the new cladding to the furring strips over the rigid foam for the exterior wall retrofit.
