Extruded Polystyrene (XPS) Rigid Foam Insulation
components of common soils
and will retain its insulating
performance characteristics
even after prolonged exposure
to moisture.
• Provides a weather resistant
barrier (when joints are
sealed) to enhance the building
resistance to air and moisture
penetration.
Technical Information
This product is combustible. A
protective barrier or thermal
barrier is required as specied in
the appropriate building code. For
additional information, consult
MSDS or contact Owens Corning

.
All construction should be
evaluated for the necessity to
provide vapor retarders. See
current ASHRAE Handbook of
Fundamentals.
FOAMULAR

150 Extruded
Polystyrene XPS Rigid Foam
Insulation is a non-structural
material and must be installed on
framing which is independently
braced and structurally adequate
to meet required construction
and service loading conditions.
FOAMULAR
®
XPS Insulation
can be exposed to the exterior
during normal construction
cycles. During that time some
fading of color may begin due to
UV exposure, and, if exposed for
extended periods of time, some
degradation or “dusting” of the
polystyrene surface may begin. It
is best if the product is covered
within 60 days to minimize
degradation. Once covered, the
deterioration stops, and damage
is limited to the thin top surface
layers of cells. Cells below are
generally unharmed and still
useful insulation.
FOAMULAR

150 Extruded
Polystyrene XPS Rigid Foam
Insulation has a maximum
service temperature of 165°F.
Taking simple precautions during
construction can minimize
the potential for heat related
damage. Install only as much
FOAMULAR

XPS Insulation
as can be covered in the same
day. For horizontal applications,
always turn the print side down
so the black print does not show

1. Properties shown are representative values for 1" thick material, unless otherwise specied.
2. Modied as required to meet ASTM C578
3. R means the resistance to heat ow; the higher the value, the greater the insulation power. This insulation must be
installed properly to get the marked R-value. Follow the manufacturer’s instructions carefully. If a manufacturer’s
fact sheet is not provided with the material shipment, request this and review it carefully. R-values vary depending
on many factors including the mean temperature at which the test is conducted, and the age of the sample at
the time of testing. Because rigid foam plastic insulation products are not all aged in accordance with the same
standards, it is useful to publish comparison R-value data. The R-value for FOAMULAR® XPS Insulation is provided
from testing at two mean temperatures, 40ºF and 75ºF, and from two aging (conditioning) techniques, 180 day real-
time aged (as mandated by ASTM C578) and a method of accelerated aging sometimes called “Long Term Thermal
Resistance” (LTTR) per CAN/ULC S770-03. The R-value at 180 day real-time age and 75ºF mean temperature is
commonly used to compare products and is the value printed on the product.

5. Value at yield or 5%, whichever occurs rst.
6. Data ranges from 0.00 to value shown due to the level of precision of the test method.
7. Water vapor permeance decreases as thickness increases.

conditions.
