Installation Procedures for THERMAX
™
Light Duty Insulation on Tilt-up Walls
®™Trademark of The Dow Chemical Company (“Dow”) or an affiliated company of Dow
*International Energy Conservation Code (IECC) at www.energycodes.gov and American Society of Heating, Refrigerating and Air-Conditioning Engineers at www.ashrae.org
THERMAX
™
Light Duty Insulation,
when installed on the interior of
tilt-up concrete walls, enhances the
building’s thermal performance and
moisture management and helps meet
continuous insulation requirements
mandated by energy efficiency codes
and standards, such as IECC and
ASHRAE 90.1.* The product can
be installed exposed to the interior
without a thermal barrier.
THERMAX
™
Light Duty Insulation
is lightweight and easy to install and
can be adhered directly to concrete
or masonry walls. It consists of a
glass-fiber-reinforced polyisocyanurate
foam core laminated with a 1.25
mil embossed white acrylic-coated
aluminum facer on one side and
1.25 mil embossed aluminum on
the other side. The facers make it a
durable choice for use in light-impact
areas. It can be pressure-washed up to
1,000 psi with a 15-degree or greater
spray tip (at minimum 3' distance).
