Architectural Collection Vented Cut-To-Width (CTW) sot pro-
vides a minimum ventilation of 10-in
2
per linear foot from the
factory
Choose Precision Series 38 Series or Foundations 76 Series sot
for closed sot application. Precision Series 76 and 190 Series
sot for open sot applications. Consult your local building code
for guidance if it is necessary to rip the Precision Series 76 and
190 Series sot in open sot applications.
Recommended spans for open and closed sots are given in
Table 1. The recommendations in Table 1 for open sots also
apply to combined roof/ceiling construction. Panels are assumed
continuous over two or more spans with the long dimension or
strength axis across supports for both applications.
Precision Series 76 and 190 Series 4 ft. wide sot is designed for
open sot applications (Figure 1) although it is suitable for closed
sot applications also (Figure 2). Precision Series 38 Series and
Foundations 76 Series sot can be used for closed sot only
(Figure 2).
In open and closed sot construction, protect panel edges
against direct exposure to the weather with LP SmartSide trim
and fascia. Apply LP SmartSide sot in a manner that prevents
moisture intrusion and water build-up. All openings, other than
the vents, must be sealed, caulked, and/or flashed.

DO
• Priming all exposed wood substrates before painting is highly
recommended.
• Paint all exposed sot surfaces including drip edges.
• Thoroughly paint the bottom edges of sot especially
all cut ends next to the roof line.
• Apply paint as soon as possible and within 180 days of application.
• Follow the coating manufacturer's application and maintenance
instructions.
• High-quality acrylic latex paint, specially formulated for use on
wood and engineered wood substrates, is highly recommended.
Semi-gloss or satin finish oil or alkyd paints are acceptable. For
flat alkyd paint, please check with the coating manufacturers for
their recommendations for use on composite wood siding.
NOT RECOMMENDED:
• Semi-transparent stain.
• Shake and shingle paints.
• Vinyl-based resin formulas such as vinyl acetate, PVA,
vinyl acetate/acrylic copolymer paints.

• Panels must be installed perpendicular to supports.
• Minimum size framing should be nominal 2 in. x 4 in.
• All panel edges must be supported or backed by solid framing.
• Consult your local building code for open sot applications.
• Space nails 6 inches at panel edges and 12 inches at
intermediate supports.

• When installing the Architectural Collection
vented sot, avoid cutting through the vented areas.
If it cannot be avoided, take special precautions to avoid
damage to the spokes within the vent.
• The spokes within the vent may warp slightly during
equilibration with the local environment. This condition is
temporary and the spokes will straighten.
• Factory manufactured Cut-To-Width sot is approved for use
in closed sot applications only.
• Field prepared Cut-To-Width sot should comply with local
building codes.
• Space the end and edge joints 1/8 in. when using 8-foot sot.
• Space the end and edge joints 3/16 in. when using 16-foot sot.
• LP SmartSide Sot products are not designed for and are not
suitable for use as siding or trim.
