Johns Manville FSK-25 faced insulation is a lightweight flame resistant thermal and acoustical fiber glass insulation made of long, resilient glass fibers bonded with a thermosetting resin. The batts are laminated with an FSK (foil-scrim-kraft) facing, which enables the insulation to carry a fire hazard classification rating of 25/50 or less per ASTM E84 and also serves as an excellent vapor retarder. FSK-25 faced insulation may be left exposed where codes permit.

  • Formaldehyde-free - will not off gas formaldehyde in the indoor environment
  • Thermally efficient - provides effective resistance to heat transfer with R-values upto R-30 (RSI-5.3)
  • Sound control - reduces transmission of sound through exterior and interior walls and floor or ceiling assemblies
  • Fire resistant
  • Durable inorganic glass - will not rot, mildew or deteriorate and is non-corrosive to pipes, wiring and metal studs
  • Superior performance - bonded glass fibers are dimensionally stable and will not slump within the wall cavity, settle or break down during normal applications
  • Light reflective - reflective surface helps maximize lighting efficiency and may reduce lighting requirements
