Installing CedarBoards Insulated Siding
CedarBoards Insulated Siding will help even out wall surfaces.
However, to minimize extremes in the peaks and valleys of uneven
walls, you may have to repair the underlayment. Make sure
the substrate is smooth, flat, and weathertight. If the surface is
significantly uneven, apply 1/4" (minimum) foam sheathing before
installing CedarBoards Siding. If the wall surface is smooth, use
standard underlayment practices.
Horizontal Siding
The key to creating a visually attractive installation is to lap
away from areas where people normally walk or gather.
For example, on the front wall, work from the corners to the
entrance door (so overlaps face away from door).
On side walls, work from the rear corners toward the front. This
approach minimizes the effect of lapping and produces the best
appearance. Keep lap appearance in mind throughout installation.
Starter strips
Insulated siding is thicker than hollow vinyl siding. To accom-
modate the 1-1/4" thickness, we recommend that you use the
CedarBoards starter strip.
An alternative method of starting CedarBoards is to use 1-1/4"
J-Channel in place of starter strip to receive the bottom edge of
the panel.
Fastening
Use 2" (minimum) corrosion-resistant nails to penetrate the wood
substrate at least 3/4". Drive the nails until there is 1/16" between
the nail head and the nail flange.
Center the nail in the slot and drive the nail straight in. Do not drive
nails at an angle. Space nails 16" o.c.
STUDfinder Installation
The STUDfinder
™
Installation System combines precisely
engineered nail slot locations with graphics to create a siding
panel that is designed to help ensure quick, accurate and secure
installation. The nail slots are positioned 16" on center to allow for
alignment with studs, with STUDfinder graphics centered directly
under each nail slot.
Locate the first stud and fasten in the center of the nail slot.
Ensure that nail penetration is at least 3/4" into framing members
to comply with ASTM D4756 (specification for vinyl siding
installation). Notice which STUDfinder letter appears below the slot.
