NOTES:

1. CONTRACTOR TO VERIFY COMPONENT CLEARANCE REQUIREMENTS AND MAINTAIN ALL RATED WALL ASSEMBLIES.

2. CAREFULLY REMOVE EXISTING CLADDING, TRIM, WRB, AND ASSOCIATED FLASHINGS ALONG ELEVATION AREAS TO

BE REHABILITATED.

3. METAL THRU WALL FLASHING IS TO BE COMPLETE WITH UPTURNED ENDS AT TERMINATIONS AND CONTINUOUS

AROUND CORNERS. SLOPE HORIZONTAL LEGS TO DRAIN, REFER TO DETAIL 1/A3.01

4. APPLY PRIMER TO CONCRETE SLAB AND FOUNDATION WALL SUBSTRATES PRIOR TO SAM APPLICATION SAM.

5. SHEET METAL FLASHING IS TO FULLY COVER SAM AND ICE AND WATER SHIELD MATERIALS ENTIRELY FROM UV

EXPOSURE.

6. INSTALL LOW EXPANDING FOAM AROUND ALL PENETRATIONS TO LIMIT AIR LEAKAGE.

7. IF PENETRATION DOES NOT FALL ALONG FRAMING, INSTALL STRAPPING OR BLOCKING AND INTERMEDIATE

FURRING STRIPS AS NEEDED FOR BLOCK AND SIDING TERMINATIONS.

8. PROVIDE EXTENSIONS WHERE NEEDED TO PIPES, DUCTS, AND OTHER PENETRATIONS TO ACCOMMODATE

INCREASED THICKNESS OF WALL ASSEMBLIES.

9. PRIME AND PREP CLADDING AND TRIM AS REQUIRED TO RECEIVE SEALANT AND PAINT.

10. ISOMETRIC DETAILS ARE INTENDED TO ILLUSTRATE THE RECOMMENDED SEQUENCE OF COMPONENT

INSTALLATION AND GENERAL SHAPE AND PROFILE CONCEPTS OF FLASHING, WATERPROOFING, AND TRANSITION ASSEMBLIES. CERTAIN ADJACENT COMPONENTS HAVE NOT BEEN ILLUSTRATED FOR DETAIL CLARITY.

11. TREAT ALL CUT EDGES AT PRESSURE-TREATED LUMBER, INCLUDING KERF CUTS, WITH COMPATIBLE TREATMENT

SOLUTION PER AMERICAN WOOD PROTECTION ASSOCIATION - AWPA - M4.
