A piece of siding is used as sill extension and to provide slope in the opening for the window, which is deeper because exterior rigid foam has been added
Image
A wall assembly approved for use in the wildland-urban interface has 5/8-inch type X gypsum installed exterior of the wood sheathing and an exterior covering or siding that has a 1-hour fire-resistance rating

Image
End conditions for braced wall lines with continuous sheathing, Figure R602.10.7 in the IRC
Image
Improper continuous load path design lacking bracing results in the failure of gable end walls under high wind conditions.
Image
Incorrectly done seismic retrofit, the plywood sheathing is not nailed to the mud sill and therefore it is not providing any shear strength
Image
Image
Install the house wrap. Cut house wrap to fit over diverter and tape top of cut wrap
Image
Insulating sheathing is installed on exterior of an existing framed wall with water control between existing sheathing and insulating sheathing
Image
Image
Image
Image
Image
Right - A continuous load path connects the roof and wall framing to the foundation.
Image
Right - Braced wall line spacing is correctly calculated for determining wall bracing in accordance with the IRC.
Image
Right - Foil-faced polyisocyanurate rigid foam is attached to the existing exterior wall with vertical wood furring strips
Image
Right - This foil-faced polyisocyanurate rigid foam is installed on an existing exterior wall and the seams are taped so the rigid foam can serve as a water control layer
Image
Image
Right – This foil-faced foam sheathing has taped seams and proper flashing details so it can serve as a drainage plane.
Image
Step 1. Remove the existing wall cladding to prepare to retrofit an exterior wall.
Image
Step 2. Install a continuous air and water control layer over the existing wall sheathing.
Image
Step 4. Install insulating sheathing and vertical furring strips on the retrofitted exterior wall; seal around pipe or duct with urethane sealant.
Image
Step 5. Install sheathing tape flashing over the duct or pipe and wood blocking on either side for later attachment of trim.
Image
Step 6. Install vent hood trim block, metal cap flashing; seal top edge of flashing with sheathing tape.
Image
Image
Step 8. Attach the new cladding to the furring strips over the rigid foam for the exterior wall retrofit.
Image
The flush cut method for seismic retrofit bracing of a cripple wall allows the plywood sheathing to be attached directly to both the cripple studs and the notched section of the mudsill
Image
Image
The reverse block method for seismic retrofit bracing of a cripple wall uses a 2x4 attached to the sill plate to provide a means to attach the plywood cripple wall sheathing to the sill plate
Image
This farmhouse was retrofit by removing the existing siding and adding taped insulated sheathing and battens before installing new siding
Image
Upper-floor tie to lower floor for two-story building. Floor tie anchor and nailed wall sheathing.
Image
With the nailed block method, wood blocks are attached to the sill plate and the cripple wall plywood is attached to the block to provide shear strength for correctly bracing a cripple wall in a seismic retrofit
Image
Wrong – Either this tape was not pressed down firmly or the surface was wet or dirty so the tape is not sticking properly even during construction.
Image
Wrong – If the insulated sheathing will serve as an air barrier and drainage plane, any cuts and seams must be taped or sealed.
