Laced (Prairie-Style) Corners
Laced or prairie-style corners, which are frequently used
on single-story homes, emphasize the horizontal lines
of the siding. Laced corners are created by mating each
successive course of siding with its counterpart on the
adjoining wall. Traditionally, this involved fitting each
course of siding, marking the overlap, and removing the
marked piece to make the sloped cut corresponding to
the bevel of the opposite course. The end of every other
piece of siding is left exposed, so the panel must be
carefully sealed to prevent it from absorbing moisture.
Note that accurate coursing is essential, because
there’s no intervening corner board to conceal any slight
irregularities in alignment.

Laced Corners
To create a laced (or prairie-style) corner:
XXFlash all corners. CertainTeed recommends installing
prefinished metal flashing that extends a minimum of
10" on each side.
XXInstall the first board flush with the corner of
the sheathing.
XXInstall the board on the intersecting wall so that it
overlaps the width of the previous board.
XXReverse this pattern on the next course of siding.
XXAs you work your way up the wall, alternate the
pattern, so the joint lines between the corner
boards are staggered.
XXSeal the exposed edges of the siding so that they do
not absorb moisture.
NOTE: Do not use prefinished product to create
laced corners.
Section 11 :
Shapes Siding
Before you install the siding, review and comply with
all local building codes and regulations regarding wall
construction including the proper use of sheathings,
framing, weather-resistant barriers, flashings and other
building materials and systems.
Before You Begin
Review the general cutting, fastening, and wall
preparation instructions in the Cutting, Fastening, and
Wall Preparation sections. Some important reminders:
XXCut WeatherBoards Fiber Cement Shapes face down
with mechanical shears or a circular saw. To prevent
marring the surface of the siding, cover the saw table
with a carpet or other soft material.
XXPrime, paint or caulk all field-cut edges of siding.
Do not prime or paint the back of the panel.
Refer to instructions on butt joints and trim
locations for specific requirements.
XXBe sure to install all siding with the proper textured,
sealed, or painted surface facing out.
XXDo not over drive the fasteners. When a fastener is
driven below the surface of the siding, its holding
power is reduced.
XXIrregularities in framing may be visible in the finished
application. To minimize the effect of uneven walls,
shim the wall as necessary.
XXIf you are hand nailing, it may be necessary to predrill
to help prevent the corners from breaking.
NOTE: Because of the random nailing pattern, all
panels except Perfection Shingles must be installed
over structural rated sheathing. Fasteners may
or may not hit framing/stud locations. Minimum
structural sheathings are 7/8" OSB or 1/2" plywood.
