Installation Guide

Description
InsulFoam I is a versatile insulation consisting of a superior
closed-cell, lightweight and resilient expanded polystyrene
(EPS). InsulFoam I meets or exceeds the requirements of
ASTM C578, Type I, Standard Specification for Rigid, Cellular
Polystyrene Thermal Insulation. InsulFoam I has a nominal
density of 1.0 lb/ft
3
. In addition, InsulFoam I offers a long-
term, stable R-Value and has excellent dimensional stability,
compressive strength and water resistant properties.
Uses
InsulFoam I is a quality EPS product and is used in numerous
building construction applications.
Roofing: InsulFoam I is well-suited for single ply roof appli-
cations that employ mechanically fastened or ballasted TPO,
PVC, EPDM and CSPE, as well as low-sloped built-up, modi-
ed bitumen and fully adhered single ply roofs that incorpo-
rate cover boards or slip sheets. Please consult local building
codes and membrane manufacturers for system require-
ments.
Other Construction Applications: InsulFoam I is used in
assorted building applications, including pre-stressed and
pre-cast structural concrete panels, metal roof ute-ll, siding
backer board, building sheathing, roads and bridge ll, below-
slab and perimeter insulation, and numerous other geofoam
applications.
Advantages
Environmentally Friendly. It contains no formaldehyde or
ozone-depleting HCFCs, contains recycled material, and
is 100% recyclable if ever removed or replaced.
Stable R-Value. Designers are well served knowing the
product’s thermal properties will remain stable over its
entire service life. There is no thermal drift, so the product
is eligible for an Insulfoam 20-year thermal performance
warranty.
Proven Performance. The same fundamental EPS chem-
istry has been in use since the mid-1950s, so the actual
performance of the product is well known.
Water Resistant. InsulFoam I does not readily absorb
moisture from the environment.
Code Approvals. InsulFoam I is recognized by the Inter-
national Code Council Evaluation Service (ICC-ES), and
has numerous Underwriters Laboratory and Factory
Mutual Approvals. Please contact your local Insulfoam
representative for details.
Sizes
InsulFoam I is typically available in 4' x 4' and 4' x 8' sizes with
thickness from 1/4" to 40", and is readily available in custom
lengths and widths with little to no impact on lead time. It is
also available in tapered panels.
