Polyisocyanurate foam is a rigid foam
which has the highest insulating values of any conventional
foam insulation commercially available today. Very low
conductivity gases trapped in the closed-cell structure
also reduce heat transfer by conduction, thereby further
increasing the thermal efficiency of these foams. The
small cell size practically eliminates convection, another
source of energy transfer. Every cell wall acts as a
barrier to energy transmission by radiative heat transfer.
The package of these properties comes with a material
that can be used in service between –100° F
to 200° F. It is moisture resistant, dimensionally
stable, air tight, resistant to the transfer of heat
through the building envelope, and has the ability to
perform a structural role.Polyisocyanurate foam is generally
low density, insulation-grade foams, usually made in
large blocks via a continuous extrusion process. These
blocks are then put through cutting machines to make
sheets and other shapes. Polyisocyanurate foams have
excellent insulating value, good compressive-strength
properties, and temperature resistance up to 300 degrees
F.
Trymer®
TRYMER® rigid foam insulation is a highly moisture-resistant,
modified polyisocyanurate bunstock. It is available
in a range of densities and compressive strengths
for a variety of applications1 including pipe and vessel insulation, core materials
for structural panels, doors and others requiring
dimensionally stable insulating composites within
the service temperature range of -297ºF
to +300ºF (-190ºC to + 149ºC).2 |

THERMAX®
 THERMAX® Metal
Building Board is a polyisocyanurate foam core insulation
with an embossed aluminum foil facer on both sides. These
aluminum foil facers serve to dampen the noise resulting
from the system's movement when outside temperatures change.
Can be installed exposed to the interior without a thermal
barrier.
