 At the time of manufacture, siding meets 
or exceeds the performance standards set 
forth in ICC-ES-AC321 and has achieved 
code recognition under ESR-1301, CCNC 
11826, APA recognition under PR-N124, 
and HUD recognition under HUD-MR-1318. 
(
For copies of ESR-1301, call LP Support at 1-800-

•   Minimum 6 inch clearance must be 
maintained  between  siding  and  nish 
grade.
•   Siding applied adjacent to porches, 
patios, walks, etc. must have a clearance 
of at least 1 inch above any surface.
•   Minimum 1 inch clearance at intersection 
with roof line.
•   Apply siding in a manner that prevents 
moisture intrusion and water buildup.
•   All exposed wood substrate must 
be sealed in a manner that prevents 
moisture intrusion and water buildup.
•   LP

 does not recommend LP
®
SmartSide
®
Panel for use in ICF and SIP assemblies. 
•   If used, LP
®
 will not warrant for buckling 
and shrinkage. However, balance of 
warranty does remain intact.
•  Do not use staples. 
•   Siding must not be in direct contact with 
masonry, concrete, brick, stone, stucco, 
or mortar. 
HORIZONTAL TRIM
•  Properly  integrate  ashing  with siding, 
WRB and vertical trim. 
•  At corners, allow the end of the trim to 
overlap the end of the adjoining trim. 
Leave a 3/16 inch space and seal with 
sealant.
STUD AND SPACING 
•  Diamond Kote
®
 Building Products must 
be applied over sheathed walls into studs 
spaced no greater than 16" on center.
•  Installations over masonry walls, the wall 
must be furred out with wood framing 
spaced 16" on center and with adequate 
thickness to accept the full length of the 
recommended nail. 
TRIM & FASCIA     190, 440, 540 & 2000 SERIES
INSTALLATION
• Trim must extend beyond the face of the siding. Trim may be
installed directly to the sheathing, or directly over the siding.
• Horizontal trim: properly integrate ashing with siding, WRB
and vertical trim. At corners, allow the end of the trim to overlap
the end of the adjoining trim. Leave a 3/16 inch space and seal
with sealant. (See diagram 6a)
• Vertical corners directly to sheathing: allow for proper spacing
between the trim edge and siding. Corner trim edge may
lightly touch adjacent trim edge. Follow siding manufacturer’s
application instructions.  (See diagrams 6b and 6c)
• Vertical corners over siding: the width of the trim must overlap
the siding by a minimum of 2 inches. Sealant between the trim
and siding is not required for this application. Allow for proper
spacing at the corner between perpendicular siding pieces.
Corner trim edge may lightly touch adjacent trim edge. Follow
siding manufacturer’s application
instructions.  (See diagram 6d)
• OPTIONAL Pre-assembled vertical corners: cut vertical
corner pieces to size with clearance requirements in mind. Set
perpendicular corner pieces and pre-drill fastening holes a
minimum of every 24 inches o.c. Fasten into pre-drilled holes with
proper nails or screws. (See diagrams 6e and 6f)

TRIM & FASCIA     190, 440, 540 & 2000 SERIES
PREPARATION
•  Minimum 6 inches clearance must be maintained between trim
and nished grade. (See diagram 2a)
•  Trim applied adjacent to roofs, porches, patios, sidewalks, etc.
must have a clearance of at least 1 inch above any surface where
water might collect. The surface must be sloped or otherwise
designed to provide proper drainage so the trim is at no time
directly exposed to standing water. (See diagram 2b)
•  A non-corrosive drip-edge must be applied at bottom edge of
roong where it meets the fascia. (See diagrams 2c and 9c)
•  In a horizontal brick frieze or band board application where the
trim meets the masonry leave a 3/8 inch minimum airspace and
ash between the trim and the masonry. (See diagram 2d)
GENERAL REQUIREMENTS (CONTINUED)
•  For the cleanest cut and longer blade life, a ne-tooth carbide
tipped blade is recommended.
•  Trim and fascia are manufactured with a special edge coating
which reduces moisture-related issues. Do not rip and/or rout
the trim and fascia, as it will leave the edges unprotected. If the
trim or fascia materials are ripped you must take special care to
prime, paint and seal all exposed wood ber as described in the
nishing section.
•  Climb cut the surface of the trim and fascia such that the rotation
of the blade cuts downward on the primed or prenished
surface.
•  Do not miter trim ends or edges. 45 degree diagonal cuts of trim
ends around door and window opening is acceptable, as well as
joining. (See diagram 2e)
