EXTERIOR INSULATION + STRUCTURAL PANEL + WATER RESISTANT BARRIER
I N O N E PA C K A G E
Introducing patent pending ThermalStar® LCi-SS™,
a continuous insulated structural sheathing
product for residential, multi-family and light
commercial construction, that meets R3 (climate
zone 4), R5 (zone 5), and R7.5 (zone 6) assembly
rating for IRC prescriptive “ci” use. LCi-SS
is an innovative solution because it reduces
material and labor costs by combining continuous
envelope insulation, code prescriptive structural
capacity and a water resistant barrier all in one
product. With LCi-SS, you receive the “building
science” advantages of continuous envelope
insulation (a significant reduction in air infiltration,
thermal bridging and potential moisture issues)
while attaining a higher overall R-value. LCi-SS
also saves money over both typical R20
2 x 6 construction and other continuous insulation
methods. Since LCi-SS is installed with our patent
pending nailing system, there are no structural
compromises that are commonly associated with
other composite continuous insulation products.
When have you had an opportunity to offer your
customers a performance advantage that saves
them money?

T h e r e is a sound r e a s o n w h y a r c h i t e c t s ,
engineers, building s c i en c e prof e s sionals
and energy codes are pushing towards
adoption of continuous exterior insulation.
Continuous insulation provides lower moisture
r i s k , h i g h e r overall R-value and less air
infiltration over ty pi c al 2 x 6 wall systems. The
following compares a R1 3+5 wall system with
a standard R20 2x6 wall design.

CONVENTIONAL 2x6
WALL C O N S T R U C T I O N
•Thermal bridging wood structural components are
covered from foundation to gable top. The temperature
inside the wall cavity of a +5 wall in cold climates is
approximately 25 degrees higher than a thicker, R20 wall.
This moves the dew point outside the wall cavity reducing
potential condensation issues.
•Without continuous insulation, approximately 25% of
a wall is comprised not of insulation, but rather wood
components (studs, headers, plates and other lumber).
•Each wood component is a thermal gap in the exterior
building envelope, allowing the heat and cold to conduct
into and through the structure of a building. This is called
thermal bridging.
•Thermal bridging creates lower wall cavity temperatures
(up to 25 degrees) over a continuous exterior insulated
wall that is prone to damaging moisture condensation
on cold surfaces and assuring the dew point of the wall
system is effectively inside the wall system.
•The whole wall R-value of a R13+5 wall construction is
17.26, or over 10% higher than a 2 x 6 R20 wall!
•Air infiltration leakage points are greatly reduced at rim
joists and other problem areas. Blower door tests are
much easier to pass with LCi-SS.
A 13+5 wall built with ThermalStar LCi-SS has a higher
R-value, less air infiltration, better moisture & thermal
performance, covers hard to insulate areas like the rim
joists & actually costs less than an R20 wall.
•When a wall system is compromised by thermal bridging,
the whole wall R-value of a conventional 2 x 6 is not R20–
but actually R15.67.
ThermalStar LCi-SS is 3rd party evaluated for code prescribed racking by DrJ Engineering (TER 1311-02), has water resistive barrier and fire
code approvals by UL (UL ER16529.1).
THE THERMALSTAR LCi-SS
INSTALLATION ADVANTAGE
LCi-SS is installed with a patent pending nail gun. This nail
gun, and Senco nails must be used for installation in order
for limited lifetime warranty to apply. This nail gun ensures
that the sheathing nails used are installed and secured with
the heads correctly seated on the surface of the OSB. Other
composite insulation sheathing products have non-typical
nailing design specifications that may cause compromised
structural capacity. LCi-SS is prescriptively nailed, which
classifies the product as continuous sheathing (CS) in the IRC.
Just like typically installed wood sheathing, which has proven
structural performance over decades and millions of homes,
LCi-SS does not have structural compromises. The insulation
layer is permanently adhered to the OSB with polyurethane
technology, so there is no worry of de-lamination over time.

LCi-SS INSULATED SHEATHING
• Available sizes: 4’x8’, 4’x9’ or 4’x10’ sheets
• Manufactured with EPSx® technology, providing integrated
termite protection and wax matrix for excellent moisture
resistance.
• Use of LCi-SS creates no structural compromises.
• Manufactured with 7/16” Exposure I PS2-04 16/24” OSB.
Since it connects the OSB directly to the stud with a proprietary
and patent pending nail gun, LCi-SS qualifies as continuous
sheathing.
• Meets code prescriptive insulation requirements as
the +5 component of a 13+5 system equal to R20,
equal to U 0.057.
• Most siding, brick veneers, thin set veneers and
stucco systems can be applied over LCi-SS.
LCi-SS is easy to use, however, for best use,
please refer to the installation manual for
full instructions and details.

• LCi-SS cuts and routes just like standard OSB.
• LCi-SS is fastened with a proprietary Senco nail gun and
nails. This nail gun is specifically designed to drive the
sheathing fastener through the foam layer seating the nail
head directly on the surface of the OSB. These nail guns are
available wherever LCi-SS is sold.
• LCi-SS is taped at the joints and edges to enhance air
infiltration performance instead of using housewrap.
• Siding can be applied directly over the LCi-SS. Check
installation directions for fastener requirements.
• Window installs and associated flashing are
largely unchanged.
