• 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, CCMC 11826-L,

• Panel siding with SilverTech or SmartFinish is speciﬁ cally for

sheds and other outdoor structures where the interior wall

cavities will remain permanently exposed.

• Non-grooved square edge panel siding may be installed vertically

or horizontally. Shiplap edge panel siding is limited to vertical

applications.

(Figure 5E, 5F and 5G)

• Minimum 6 inch (152 mm) clearance must be maintained

between siding and finish grade (ground cover).

• Siding applied adjacent to surfaces such as porches, patios,

balconies, or walking surfaces (including porch columns) must

have a clearance of at least 1 inch (25 mm) above any horizontal

surface. Clearance may be reduced to 3/8 inch (10 mm) for:

- Porches, patios, balconies, or walking surfaces that slope

away from the structure or the surface provides gaps that

allow water to ﬂ ow through so that it cannot accumulate,

and are covered by a roof, not an eave or overhang; or

- Porch columns with walking surfaces that slope away from

the structure or the surface provides gaps that allow water

to ﬂ ow through so that it cannot accumulate.

•

Minimum 1 inch (25 mm) clearance at intersection with roof line.

• Apply and maintain siding in a manner that prevents moisture

intrusion and water buildup.

• All wood substrate that is exposed to the weather must be

sealed in a manner that prevents moisture intrusion and water

build up.

- Seal ALL exposed cuts of siding and trim. Field spray

applied coatings on cuts are not recommended.

- Sealing can be accomplished by applying a paint or

sealant according to the manufacturer’s requirements.

• LP does not recommend panel siding for use in ICF assemblies.

If used, LP will NOT warrant for Buckling and Shrinkage.

•

Use nails to fasten panel siding to structural framing.

- Alternate fasteners such as staples are permissible when

allowed by local building code and where the size,

embedment, placement and number of alternate fasteners

fasteners are designed by a licensed design professional

and approved by the local building o cial.

- LP will not consider any warranty claims for damage or

performance failures to the extent caused by the use of

any alternate fasteners.

• SIDING MUST NOT BE IN DIRECT CONTACT WITH MASONRY,

SUCH AS, BUT NOT LIMITED TO CONCRETE, BRICK, STONE,

STUCCO OR MORTAR.

• Moisture control and water vapor control are critical elements

of proper housing design. Check your local building code for

application procedures for handling moisture and water vapor.

•

As with all wood products, do not apply engineered wood siding

to a structure having excessive moisture conditions such as

drying concrete, plaster or wet blown cellulose insulation.

• Siding must not be applied to green or crooked structural

framing members.

• Siding must not be applied over rain-soaked or buckled

sheathing materials.

• Gutters are recommended for control of roof water run o .

• Panel siding with a shiplap joint must be installed with the

long dimension vertically on studs.

- 38 and 76 Series panel siding may be installed directly to

studs spaced a

maximum of 16 inch (406 mm) o.c.

- 190 Series panel siding is required when installing directly

to studs spaced up to a maximum of 24 inch (610 mm) o.c.

• Handle preﬁ nished panel siding with extreme care during

storage and application.

• Keep siding clean and dry. Inspect prior to application.

• Store o the ground on a ﬂ at surface and under a roof or

separate waterproof covering.

- Additional support may be required to achieve a safe

clearance from the ground.

- When the covering is removed, cut all unit banding.

• When unpackaging preﬁ nished siding products, cut the full

length of the shrink-wrap to avoid dragging and scu ng of

the trim or sidings painted surface.

- All movement or transportation of siding products on the

jobsite should be done with slip sheets intact.

- DO NOT remove slip sheets placed between the trim or

siding painted surfaces until each piece is being prepared

for installation.

- Early removal of the slip sheets will leave siding products

exposed to possible paint damage before installation.

• Touch up any damage to preﬁ nished siding that may occur

during application per the Finishing section in this document

or per the Preﬁ nishers speciﬁ cations.
