Specification

R-Tech
®
Insulation
Description
R-Tech is a high-performance rigid insulation consisting of
a superior closed-cell, lightweight and resilient expanded
polystyrene (EPS) with advanced polymeric laminate facers.
R-Tech is available with factory adhered metallic-reective
facers, white facers or a combination of the two. The core
of R-Tech is the same high-quality as our InsulFoam
®
brand
insulations and meets or exceeds the requirements of ASTM
C578, Type I, Standard Specication for Rigid, Cellular Poly-
styrene Thermal Insulation. In addition, R-Tech has excellent
dimensional stability, compressive strength and water-resis-
tant properties. R-Tech is an ENERGY STAR
®
qualied insu-
lation and qualies for LEED points.
Uses
R-Tech has been used successfully for numerous commer-
cial, industrial and residential applications. The following are
examples of the many R-Tech uses:
Environmentally Friendly. R-Tech contains no dyes, may
contain recycled material and the foam core is 100%
recyclable.
User Friendly. R-Tech can be ordered with the Insul-
Snap™ feature which scores the product longitudinally
at any pre-ordered interval (commonly 16" or 24" o.c.).
The InsulSnap feature minimizes labor by enabling the
installer to cleanly break the product at the desired width
while also minimizing product breakage and waste.
Insect and Mold Resistant. R-Tech is manufactured with
an inert additive that deters termites and carpenter ants.
R-Tech does not sustain mold and mildew growth.
Water-Resistant. R-Tech facers provide a surface that is
virtually impervious to moisture.
Jobsite Durability. With a polymeric facer on either side
of the R-Tech, it is an extremely exible and durable in-
sulation.
Stable R-Value. R-Tech has no thermal drift. Designers
are well served knowing the R-Tech thermal properties
will remain stable over its entire service life. R-Tech is
eligible for an Insulfoam 20-Year Thermal Performance
Warranty – a warranty that’s not prorated or limited to a
percentage of the published R-Value.
Sizes
R-Tech is available in 4' x 8' sheets with thicknesses from 3/8"
to 5" in 1/8" increments. R-Tech can also be ordered with the
InsulSnap feature which allows the end user to cleanly break
the 4' x 8' sheets into any desired width. All of the R-Tech
insulation products are available with metallic reective and
InsulFoam white facers. In addition, custom sizes and densi-
ties are available upon request with little or no impact on lead
time.
Installation Recommendations
Please refer to the appropriate R-Tech application sheets for
recommended installation procedures.

Cost-Effective. R-Tech is typically less expensive than
other comparable insulation products.
Proven Performance. The same fundamental chemistry
has been in use since the mid-1950s, so the actual per-
formance of the product is well known.
Enhanced R-Values. In certain applications, increased
R-Values can be obtained by placing the metallic reective
side of the R-Tech towards a dead air space. R-Value gain
is dependent on the amount of dead air space between
the R-Tech and outer surface. R-Value gains are based
on the ASHRAE Handbook of Fundamentals. See the
attached Effective R-Value chart.
