Installation Instructions

4. INSTALL "J" CHANNEL TO TOP AND SIDES
OF WINDOWS AND DOORS
Nail J Channel flush to the top and sides of doors and
window casings, following nailing instructions.
FORMING CORNERS WITH ā€œJā€ CHANNEL
Install top J Channel so that it extends beyond the
casings a distance equal to the width of the side J
Channels. Make two cuts in the base of the top J
Channel and bend the base down. The bent portion
will slide over the side J Channel and make a water
drain. Prior to installing the J Channel to the wall a 3/8ā€
bead of high quality urethane caulk should be used
behind the J Channel and Undersill Trim to prevent
water infiltration between the window or door opening
and the J Channel and Undersill Trim.
5. INSTALL FIRST SIDING PANEL
IInstall siding panels working from the outside corner
or the termination point on the wall toward the center of
the wall. This will make seam less apparent from door
opening which tend to be a focal point of visual
concern. Aluminum siding nails should be used to
install you new siding components. Nail length equals
the thickness of the wall sheathing plus an 1 1/2" into
solid framing members.
