  • With RFF foil facing, passes FTA Docket 90 requirements.
  • Thermal Performance (75°F): 0.25 K Factor at 1" and 3 oz/ft2
  • Features: Ultra low VOC, non-wicking, low odor
  • Supplied in rolls, sheets, or fabricated parts

Optional film facings can increase the durability, acoustical, and thermal properties of PFPV. Pressure sensitive adhesives can be applied to ease installation.

POLYDAMP® Melamine Foam (PMF)

POLYDAMP® Melamine Foam (PMF) is an extremely lightweight insulation material that exhibits exceptional resistance to heat, low flame propagation, and smoke. It possesses excellent thermal and acoustical insulation properties.
