VERTICAL SIDING APPLICATION continued 
Minimum Fastener Type for Batten:
•  Corrosion Resistant - (ASTM A153) Hot-
dipped galvanized or stainless steel
•  Ring Shank nails provide superior 
resistance to fastener pull-through.
•   In Hurricane-Prone Regions or locations 
where negative wind loads are a concern, 
ring shank nails should be used.
Trim nails may be used in other locations 
with the following cautions: 
•  Do not overdrive or countersink the 
fastener,  nail  ush  with  the  surface  of 
batten. 
•  Batten nails shall be installed per the 
length, placement, spacing and quantity 
requirements listed in this document. 
•  Detachment of Batten is not covered by 
the LP

whether ring shank or trim nails are used
•  Shank diameter= 0.091 inch, Head 
diameter= 0.221 inch, Length = fastener 
shall be long enough to fully penetrate 
Vertical Siding. 
•  Caution:  Choose a fastener length that 
won't damage wiring or other utilities in 
the exterior wall assembly.
Fastener Placement for Battens:
•  Maximum 3/8 inch from ends and edges 
(See Figure 1 pg. 27) 
Fastener Spacing for Battens:
•  Fastened with two nails at both ends, with 
additional fasteners spaced a maximum 
of 12 inches o.c. along alternating edges 
the length of the batten 
(Figure 1 pg. 27)
•  Do not bridge oors with Vertical Siding 
or Battens. Create a horizontal joint 
between oors.
 (Figure 4 pg. 27)
•  Vertical Siding must be applied in a 
manner that will not allow moisture 
intrusion or water buildup.
•  Refer to LP

LAP SIDING INSTALLED VERTICALLY 
•  LP

 Strand Lap may be installed Vertically 
for Board & Batten or Board-on-Board 
applications, according to the following 
requirements.
•  Siding must be installed over a minimum 
7/16 Category wood structural panel 
with an APA Trademark that contains 
the consensus Standard DOC PS 1 or PS 
2, or LP

Sheathing.
•  Lap Siding installed vertical/batten may 
only span one plate-to-plate. Due to 
expected plate shrinkage, each vertical 
application is not to span beyond one 
oor to  ceiling distance, or one  oor  to 
top of gable distance. 
(Figure 5 & 6)
•  Battens must be a minimum 0.5 x 2.5 
inches actual size. 
•  Siding must be installed over a non-
compressible drainable housewrap to 
provide drainage behind siding.
•  Touch-up paint all cut/exposed ends.
•  The edges of Lap Siding installed 
vertically must be spaced a minimum 
of 3/16 inch from each other. Spacing 
cannot exceed the distance that will 
allow a minimum 1 inch of bearing 
surface for the overlapping piece of Lap 
Siding. 
(See Figure 3 & 4 on pg. 29)
•  Sealant is not required in any vertical 
joint covered by Lap Siding or Batten 
and backed by a water-resistive barrier.
