Panel Deck FSK-25
Johns Manville Panel Deck FSK-25 faced thermal and acoustical fiber glass insulation is made of long, resilient glass fibers bonded with an acrylic thermosetting binder. The batts are laminated with FSK-25 (foil-scrim-kraft) which enables the insulation to carry a fire hazard classification rating of 25/50 per ASTM E 84 and serves as an excellent vapor retarder. Extra-wide tabs extend full length along both sides for specialty applications. The reflective facing may be left exposed where codes permit.
