27. Can LP® SmartSide® siding be fastened directly to the studs?
a. Certain LP SmartSide products can be attached to framed walls without
sheathing such as Precision series siding. Refer to the LP SmartSide
installation instructions for the specific type of LP SmartSide siding you
are using. Note that a code-approved breathable water-resistive barrier is
required between the siding and the studs.
28. Why are the LP SmartSide code reports important?
a. The code reports are published by the International Code Council and
demonstrate the safe use of the siding. The code reports are useful to
engineers, architects, and code officials to ensure the siding is used
within its design limits.
29. Is a house-wrap required behind the LP SmartSide siding?
a. A code-approved, breathable, water-resistive barrier is required behind
all LP SmartSide® siding as per the International Building Code. Refer to
the installation instructions for proper installation.
30. Can I install LP SmartSide® siding differently than what is specified in the LP
SmartSide installation instructions?
a. LP strongly recommends LP SmartSide siding be installed according to the
installation instructions. If the siding is installed in a manner inconsistent
with the instructions, the siding will continue to be warranted under the
LP SmartSide limited warranty although any issue caused by the
inconsistent installation will not be the responsibility of LP. Refer to the
installation instructions for proper installation.
31. Is LP SmartSide® siding permitted for use in California’s high fire hazard areas
specified in chapter 7 of the California building code?
a. Yes. All LP SmartSide Foundation and Precision series siding is listed by
the California State Fire Marshals office as accepted siding. Special
installation methods are required in high fire hazard zones. Refer to the
report at
http://www.lpcorp.com/Literature/LP_SmartSide_SFM_Report.pdf for
installation details.
32. Why is it important to space LP SmartSide® siding at all joints?
a. LP SmartSide siding will expand naturally as its moisture level balances
with the surrounding environment. Spacing the joints provides the
necessary room for the siding to expand. This is also an important reason
to properly apply a non-hardening caulk or sealant. Refer to the
installation instructions for proper installation.
33. Do LP SmartSide products resist wind loads?
a. Yes. Refer to the LP SmartSide code reports ESR-1301 and NER-626.

code reports ESR-1301 and NER-626.
