Radiant Comfort™ Floor Panels
PRODUCT DESCRIPTION
Radiant Comfort™
ThermalStar® Radiant Comfort™ floor panels are precision molded from expanded
polystyrene with a distinct orange color. The insulation panels form a firm base for
water heated radiant floors. Benefits to using Radiant Comfort™ include:
No stapling required– the groove channels hold the tubing right in place
x No professional design or shop drawings needed
x Eliminate the hassle with using left, right, and straight panels– one panel is used for
the entire installation
x New construction panels interlock for a secure placement and to prevent concrete
from seeping through the joints in heated slab applications

Panel Design
ThermalStar Radiant Comfort panels are available in
two types: new construction and retrofit panels. The
new construction panels are designed to be installed
prior to pouring a heated concrete slab. The retrofit
floor panels are designed to be installed above the
subfloor, and below the flooring option (hardwood
floors, ceramic tiles, carpet, etc.) Since Radiant
Comfort is manufactured out of EPS, it provides both a
heating system template and insulation. Radiant
Comfort panels save on installation time and
eliminates the guesswork for professionals and homeowners alike.
ThermalStar Radiant Comfort floor panels are backed
by a limited lifetime warranty for both physical and
thermal performance. Please visit our website for
further information.

Thermal Resistance: R means the resistance to heat flow. The higher the R-value, the greater the insulating power.
*Please allow 2-3 weeks for all Radiant Comfort shipments
**ThermalStar Radiant Comfort is elastic within 1-2% deformation. To prevent long term creep, 3:1 design safety factors
for static loads of the 10% deformation values are recommended, or use the tested 1% deformation values for design,

CHEMICAL & PHYSICAL
PROPERTIES
Table 2 Chemical Compatibility of Radiant Comfort
Physical properties of each panel can be found in Table 1, while
chemical resistance is listed in Table 2.
MOLD RESISTANCE
ThermalStar Radiant Comfort has been tested against 4 week
exposure to various mold and fungi via ASTM G21, D3273, and
C1338 with no growth of spores on the product. Radiant Comfort
provides no nutritive value for mold. However, construction
practices greatly impact mold growth, and fungi have been known
to even grow on glass.
FREEZE/ THAW EXPOSURE
ThermalStar Radiant Comfort has been tested via ASTM C1512
Moisture & Temperature Cycling for Insulation with no loss of
physical or thermal performance. This test places the product
between a cold chamber and a high humidity chamber with
temperature cycling, measuring the effect on the insulation as
natural moisture drive occurs.

Excellent = No degradation, no effect from exposure
Good = some effect from exposure, but not significant for product performance
Poor = significant degradation affecting performance, up to completely dissolving product

SAFETY
MSDS for this product available at www.atlaseps.com. Dust
generated from sanding or cutting ThermalStar Radiant Comfort
should be avoided using a dust mask as with other building materials.
Radiant Comfort is combustible and the product should be protected
from ignition sources such as open flames or welder’s torch.
ENVIRONMENTAL
ThermalStar Radiant Comfort Insulation uses air in the insulating cells,
emitting no gasses. Radiant Comfort insulation is readily accepted for
recycle. Based on extrapolation of pounds consumed and pounds
recycled, the EPS industry as a whole in North America exceeded 30%
rate of recycling in 2013. Atlas EPS is a responsible recycle partner,
visit www.epspackaging.org for a drop off location near you to continue
this success.
