PRODUCT DESCRIPTION
Rmax R-Matte Plus-3 is an energy-efficient thermal insulation
board composed of a closed-cell polyisocyanurate (polyiso) foam
core bonded to reinforced aluminum foil facers on each side. While
one side of the board has a reflective surface, the other side has
been coated to have a non-reflective white matte surface. R-Matte
Plus-3 utilizes a CFC-, HCFC- and HFC-free blowing agent
that has zero Ozone Depletion Potential (ODP) and negligible
Global Warming Potential (GWP). This insulation is suitable for
use in walls and ceilings in new construction for commercial,
residential, agricultural and industrial buildings and in thermal
retrofit construction within existing buildings.
