Product
Description
TUFF-R™ and Super TUFF-R™
polyisocyanurate insulation products
consist of a high-insulating-value,
closed-cell polyisocyanurate foam
core sandwiched between a choice
of durable exterior facers.
On TUFF-R™ insulation, one facer
is a continuous sheet of aluminum
foil; the other is a Tri-Plex facer
consisting of a three-ply laminate
of durable kraft with aluminum foil
on both sides. Where additional
durability is required, Super
TUFF-R™ insulation is a product of
choice. The Super Tri-Plex facers
are three-ply laminates of durable
polyester, kraft and reinforced
aluminum foil. One side is blue; the
other side is reflective foil. TUFF-R™
and Super TUFF-R™ insulation help
reduce air infiltration through the
wall by covering cracks between the
framing members and sealing tightly
against the studs.
Applications
Install TUFF-R™ and Super
TUFF-R™ insulation products in
residential construction where they
will be covered with a minimum of
1/2" gypsum board, or equivalent,
thermal barrier.

Physical
Properties
TUFF-R™ and Super TUFF-R™
insulation products offer high
R-value. The polyisocyanurate
insulation is created by an
exclusive free-rise manufacturing
process, which produces a
uniform, closed-cell foam for
better insulation performance.
As with all Dow polyisocyanurate
insulations, TUFF-R™ and Super
TUFF-R™ insulation products are
manufactured with hydrocarbon
blowing agents, which have no
ozone depletion potential.
For features and benefits of
TUFF-R™ and Super TUFF-R™
insulation products, refer to
Table 1.
TUFF-R™ and Super TUFF-R™
insulation products exhibit the
properties indicated in Tables 2 and

(1) R means resistance to heat flow. The higher the R-value, the greater the insulating power.
(2) Siding manufacturers may restrict warranties as applied to sheathing underlayment.
