 Spacing for the siding should be laid out
beforehand. The number of board spaces between the
soffit and bottom of the lowest piece of siding
at the foundation should be such that the overlap
is as per Table 6. The wider the siding, the greater
the overlap can be.
Start with the bottom course using a furring
strip to support the lower edge. Each succeeding
course overlaps the upper edge of the previous
one by 1 in. Rabbeted patterns are self-spacing,
but leave 1/8 in. expansion clearance. Where possible,
the bottom of the board that is placed across
the top of the windows should coincide with the
window cap.
Bevel siding should be face nailed to studs with
1-1/4 in. penetration into solid wood using one
ring shank nail per bearing spaced at a maximum
of 24 in. on center. Place nail just above the
overlap. Take care not to nail through the overlap
of two pieces (see Figure 5).
Do not reduce the siding overlap recommendations
given in the installation sections of this purblication.
To do so could result in damage from wind-driven
water.
Butt joints between boards should be staggered
and made on studs. Fit siding snugly to other
pieces and to trim.

* Use for unseasoned 10 in. bevel siding.
Notes: Do not exceed 2 in. overlap. Use the larger
overlaps for unseasoned sidings to allow for shrinkage
and expansion. Take care not to overdrive fasteners
when using larger overlaps.
