INSTALLATION
• When attaching trim as batten strips, follow the Fastening Instructions section in this document.
− Exception: When using trim less than 3 inches (76 mm) wide as battens, apply one nail per width, a maximum of
every 36 inches (914 mm) vertically.
• When batten strips are applied over panel siding at vertical joints, sealant is not required.
• When batten strips are applied to walls with horizontal panel joints, do not run battens over the panel joint and ashing.
Terminate the trim battens above and below the horizontal panel joint to allow for proper spacing and ashing.
(See diagrams 10a and 10b)
