Owens Corning® FOAMULAR® & FOAMULAR® NGX® 404/604 Extruded Polystyrene (XPS) Rigid Foam Insulations are specially designed for use in Protected Roof Membrane Assemblies (PRMA), where the insulation is placed over the membrane, providing a channelled pathway for incidental moisture to travel to roof drains. The compressive strength of FOAMULAR® & FOAMULAR® NGX® XPS Insulation provides the integrity needed for long-term roof performance.
FOAMULAR® NGX® 404/604 contains the additional benefit of being manufactured with a blowing agent formulation that delivers a 90% reduction to Global Warming Potential (100 years), including the complete elimination of HFC 134a.
