Installation Guide

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. Rmax does not recommend the direct attachment of
stucco, such as Portland cement or polymer-modified types, directly
to the face of the insulation product. Consult stucco manufacturers
for details.

Notes:
1. Stud walls must be properly braced for lateral loads
according to the requirements of local Building Codes.
Re-Siding Construction - R-Matte Plus-3 may be used in retrofit
construction provided the existing siding is sound and solidly attached.
It is secured with galvanized nails of sufficient length to penetrate the
old sidings, sheathings below and at least one inch into the existing
wall studs. Then, cover the R-Matte Plus-3 with a suitable new siding of
aluminum, vinyl, fiber cement, wood or wood fiber based products.

Notes:
1. Existing siding must be inspected and re-nailed to provide
for solid back-up to attach new sheathing and siding
materials. Deteriorated or rotted areas of existing siding
must be removed and replaced to restore original thickness.
2. Stud walls must be properly braced for lateral loads
according to the requirements of local Building Codes.

Attics and Crawl Spaces - R-Matte Plus-3 may be applied to the
interior face of stud walls or roof rafters within attics and crawl spaces to
provide a layer of continuous insulation (ci). Simply nail the R-Matte Plus-3
to the framing members and cover with an approved ignition barrier such
as 3/8" gypsum wallboard or 1/4" wood structural panel, particle board
or hardboard.
Vaulted Ceiling Construction - R-Matte Plus-3 may
be applied to the inside face of the roof rafters in vaulted ceiling
construction to provide a layer of continuous insulation (ci) and
increase the R-value of the roof. Simply nail the R-Matte Plus-3 to
the face of the rafter, cover with a minimum 1/2" gypsum wallboard and
finish.

LIMITATIONS
R-Matte Plus-3 is not recommended, nor warranted, for use as a
commercial roof insulation directly under membrane systems. Consult
Rmax Sales for suitable commercial roof insulation products.
R-Matte Plus-3 is not a structural panel. It must not be used as a nailing
base for any other building products. Furthermore, stud walls insulated
with R-Matte Plus-3 must be properly braced for lateral loads according
to the requirements of local Building Codes.
WARNING
DO NOT leave R-Matte Plus-3 exposed. Polyiso foam is an organic
material which will burn when exposed to an ignition source of sufficient
heat and intensity and may contribute to flames spreading.
Installations utilizing R-Matte Plus-3 must be fully protected on the
interior side of the building by a thermal barrier such as a minimum of
1/2" gypsum wallboard. Masonry or concrete that is a minimum of
one inch thick, plywood that is a minimum of 1/2” thick and wood that
is a minimum of one inch nominal thickness may also be recognized as
suitable thermal barriers. Consult your local Building Official for specific
governing codes and requirements.
The interior and/or exterior of the building should be protected with a
suitable vapor retarder and/or a water resistive barrier, if required, based
on local Building Codes and climate zone.
