Specification

POLY SHIELD offers tough poly facers heat laminated to a Cellofoam Expanded
Polystyrene (EPS) insulation core. Whether installed over wood sheathing or
direct-to-stud (provided lateral loads are accommodated through other means),
POLY SHIELD is the ideal solution for underlayment behind siding.
POLY SHIELD continuous insulation is approved for weather resistant
barrier (WRB) rated assemblies when taped, eliminating
the cost, installation time, and need for a house-
wrap. POLY SHIELD continuous insulation
complies with the model building codes when
properly installed as identified in Cellofoam’s UL
Evaluation Report ER7260.
POLY SHIELD’s durable poly facers are clear
with the printing on one side and reflective on the
other. If a reflective surface is not desired, clear
poly laminate can be ordered on both sides. Stan-
dard thicknesses are 1/2”, 3/4” and 1’’. Standard
density is 1.0 pcf. Other densities up to 3.0 pcf and
thicknesses up to 4” are also available.
Because POLY SHIELD is made of millions of
closed cells of expanded polystyrene, it has an excel-
lent resistance to heat transfer. Not a vapor barrier.
When POLY SHIELD is properly installed it doesn’t
deteriorate with age, is resistant to mildew, rot,
fungus, bacteria, and doesn’t require maintenance.
The tough facings resist abuse during construction
and storage/warehousing.
POLY SHIELD tongue-and-groove (T&G) EPS panels form an
ideal substrate for siding in conventional and manufactured
homes. With high energy costs and green initiatives taking hold
across the nation, the high insulating value of this building
approach is growing in popularity.
T&G's interlocking joints form a consistent insulation barrier and
a smooth surface with seamless joints for the application of
siding. The panels are moisture resistant and can absorb building
movement while reducing air movement in the wall.
