Physical Properties of Insulfoam EPS
Typical Physical Properties of InsulFoam*
The physical properties provided in this manual are average
values determined by Insulfoam, Insulfoam raw material sup-
pliers and independent testing agencies. Testing results were
obtained under controlled laboratory conditions and do not
represent minimum standards. Insulfoam is not obligated to
manufacture its products per a designer’s specifications or
physical standards unless agreed to in advance by Insulfoam.
It is the purchaser’s obligation to ensure any purchased In-
sulfoam materials meet a specification’s physical properties.
Certification
Insulfoam must be notified at the time materials are ordered
if product must be certified to meet an ASTM or other speci-
fication and/or must bear an Underwriters Laboratories, Inc
(UL) or Factory Mutual (FM) label or marking. Insulfoam will
perform the required tests and certify that materials meet
specifications, with or without exception, upon acceptance of
the order.
