STRAND SUBSTRATE 38, 76 AND 190 SERIES

PRIMED PANEL SIDING

INCLUDING SILVERTECH & SMARTFINISH

G

• At the time of manufacture, siding meets or exceeds the per-

formance standards set forth in ICC-ES AC321 and has achieved

code recognition under ESR-1301, CCMC 11826-L, APA recognition

under PR-N124, and HUD recognition under HUD-MR# 1318b. For

copies of ESR-1301, call LP Customer Support at 1-800-648-6893

• Strand Substrate panel siding with SilverTech or SmartFinish

is speciﬁcally for sheds and other outdoor structures where the

interior wall cavities will remain permanently exposed.

• Minimum 6 inch clearance must be maintained between siding

and finish 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.

S

• Store o the ground well supported, on a ﬂat surface, under a

roof or separate waterproof covering

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

G  S

• Seal all gaps with a high-quality, non-hardening, paintable

sealant. Follow the sealant manufacturer’s instructions for

application.

• Use a high-quality exterior sealant meeting the ASTM C920,

minimum Class 25 sealant.

S S

• Strand Substrate 38 and 76 Series panel siding must be installed

on 16 inch o.c. framing only. When installing on 24 inch o.c.

framing, 190 Series panel siding is required.

•

In all installations over masonry or concrete walls, the wall shall

be furred out and open at the top and bottom of the wall to allow

for convective ventilation between framing spaced 16 inch o.c. The

framing shall be of adequate thickness to accept 1-1/2 inches of nail

penetration. A properly installed breathable water-resistive barrier

is required between the siding and masonry or concrete walls.

S W-R B

• LP strongly recommends the use of a secondary water-resis-

tive barrier behind all LP SmartSide siding. A properly installed

water-resistive barrier provides a second line of defense to

incidental moisture behind the siding.

• The LP SmartSide limited warranty does not expressly or im-

plicitly cover water penetration. LP does not assume responsi-

bility for any water penetration.

• Sheds and other accessory structures that are not heated or

cooled do not require a secondary water-resistive barrier if

exempt by applicable building codes.

M

• Moisture control and water vapor control are critical elements

of proper housing design. Check your local building codes for

application procedures for handling moisture and water vapor

in your area.

• When using wet blown cellulose insulation, the insulation

must not be in direct contact with the siding and it must be

allowed to dry a minimum of 24 hours or longer if speciﬁed by

the insulation manufacturer.

• 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. If

such conditions exist, the building should be well ventilated to

allow it to dry prior to the application of the siding.

• Siding must not be applied to green or crooked structural

framing members. Do not apply siding over rain-soaked or

buckled sheathing materials.

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

• All openings must be properly sealed or ﬂashed in a manner

that prevents moisture intrusion or buildup. Several examples

that accomplish this are shown on the following pages.
