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.

Fastening
Use 2" (minimum)
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.
