HISTORIC COLLECTION | SCALLOP
APPLICATION
Apply siding over properly prepared walls.
(see general guidelines page 2)
• It is REQUIRED to use Nailable structural
sheathing. Scallops can be installed
blind fastened.
• Scallops can be installed by starting
with a starter strip or by overlapping a
previous course of lap siding
(4" minimum).
(see Figure 6)
• For scallops, start installation left to
right. It is recommended to use a 3/8"
x 4" piece of same color lap siding as a
starter shim, as this will partially show
because of the rounded bottom edge.
(see Figure 6a)
• Trim left edge so that siding section ts
against corner board, with a 3/16" gap.
(see Figure 6b)
• Butt joint seams are not required to land
on studs.
• Starting from left, level and install the
rst course of Scallops so bottom edge
is ush with the shim. Do NOT place
fasteners into bottoms of grooves or
shiplaps.
• Fasten 3/4" down from the top of panel,
into sheathing and/or framing with one
of the below options.
• For screws, fasten 12" on center use a
minimum #8 corrosion resistant tapered
head wood screw. (see Figure 6c)
• For nails, fasten 8" no center use a
minimum of 6d (0.09" shank diameter)
corrosion resistant ring shank nail.
(see Figure 6d)
• Continue row, working left to right.
Overlap shiplap butt ends without any
gap.
(see Figure 6e)
• Start subsequent courses in the same
manner by overlapping courses a
minimum of 4".
(see Figure 6f)
• Best appearance is obtained by installing
second course starter piece 21" shorter
than the rst course.
(see Figure 6)
• Start the 3rd course starter piece 27"
shorter than the 2nd course. (Figure 6)
• Repeat this sequence every 3 courses.
Shim siding at studs, as needed, to avoid
drawing siding against uneven walls.
