6 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. The U.S. FTC requires the R-value of home insulation to be
measured at 75 degrees F mean temperature. R-value claims should always be compare at
the same mean temperature. 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

NGX™ XPS Insulation is provided from testing at
mean temperatures of: -4°C (25oF), 4.4°C (40°F), and 24°C (75°F) and aging techniques of
180-day real time aged (as mandated by ASTM C578) and accelerated aging “Long-Term
Thermal Resistance” (LTTR) per CAN/ULC S770-03.
