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.

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.

Includes the ASHRAE assigned 2.77 R-value of a ¾” dead-air space against the

reflective foil side of R-Matte Plus-3 in a typical wall assembly.

Additional thermal R-values can be found on the insert to this document.

R-Matte Plus-3 is shipped in bundles that are approximately 48

inches high and wrapped in plastic for easy handling. Visit www.rmax.

R-Matte® Plus-3 APPLICATION / INSTALLATION Board Orientation – R-Matte Plus-3 conforms to the physical and thermal properties stated within this data sheet regardless of orientation. On exterior applications, R-Matte Plus-3 is designed to be covered with siding materials of aluminum, vinyl, fiber cement, wood or wood-based products, as well as brick, stone or stucco veneers.
PAGE 3
Exterior Stucco Construction - R-Matte Plus-3 may be used as the insulative sheathing under hard coat stucco finishes. It may be secured to the studs with bugle-head screws, galvanized roofing nails or common-nails driven through cap washers. Cover the R-Matte Plus-3 with a suitable separation layer such as an organic or inorganic felt. Then, attach conventional metal wire lath and expansion joints with appropriate fasteners as dictated by the local Building Code.
