A polyisocyanurate foam core 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. Available from 1/2" to 4-1/4" thick.
Can be installed exposed to the interior without a thermal barrier.
Applications
THERMAX Metal Building Board is used for exposed wall and/or ceiling insulation in
commercial and industrial buildings.
Not all sizes available for all applications.
Dow is transitioning to a new blowing agent. As a result, current R-values are
changing. New R-values are referenced in the chart provided.
