The F/R grade Foil-Scrim-Kraft Facing with 3-way scrim and 60gsm Kraft (F/R treated), mainly used as a facing and vapor of duct wrap insulation required good fire rating, also suitable for other insulation applications where a general use vapor retarder is needed.
Foil-Scrim-Kraft(FSK) Facing is also a good choice for radiant barrier applications because of this low emissivity.
