R-Matte
®
Plus-3
ADDITIONAL THERMAL R-VALUES
“R” means resistance to heat flow. The higher the R-value, the
greater the insulating power. According to the ASHRAE Handbook of
Fundamentals, the reflective foil facing of R-Matte Plus-3 contributes
additional R-value to the overall assembly when installed against a
dead air space. For example, ASHRAE assigns a 2.77 R-value to a
3/4" dead-air space against a reflective foil in a typical wall assembly.
This value is in addition to the R-value of the polyiso foam - see Sytem
R-Value below.

Thermal values are determined by using ASTM C518 test method at
75°F mean temperature on material conditioned according to PIMA
Technical Bulletin No. 101.
R-Matte Plus-3 is shipped in bundles that are approximately 48
inches high and wrapped in plastic for easy handling. Visit
