THERMAX ™ Sheathing and
THERMAX ™ White Finish (WF)
insulation offer two quick and
easy options to insulate base-
ment walls. Lightweight and
easy to install, both products
are ideally suited for exposed
basement applications, whether
the desired result is a semi-
finished or finished appearance.
THERMAX Sheathing and
THERMAX White Finish are non-
structural, rigid boards consisting
of a glass-fiber-reinforced poly-
isocyanurate foam core with
solid aluminum facers on both
sides. The exposed surface of
THERMAX Sheathing is reflective
foil, perfect for use in areas such
as a laundry room or storage
space. THERMAX White Finish
insulation features an embossed
white acrylic-coated aluminum
facer on its exposed surface,
for a clean, finished wall that
is durable and washable.
THERMAX products can be
left exposed to the interior
without a thermal barrier in
most applications.* THERMAX
insulation products are Factory
Mutual approved as “Wall-
Ceiling Construction, FM
