What is FSK Shield Insulation Facing?

Unfaced fiberglass and

Fi-Foil’s FSK Shield™ is lower

cost and more readily available

than FSK-faced Batts

FSK stands for Foil Scrim Kraft or aluminum foil bonded to kraft paper with a flame retardant adhesive and reinforced with fiberglass scrim.

FSK Shield was tested with R11, R19, and R30 unfaced batts in accordance with ASTM E-84.Primarily to provide a lower-cost alternative to FSK-faced batts, as well as, meet Class A (Flame Spread of 25 or less) requirements in ceiling and wall applications.

It is also used to insure that unfaced fiberglass batt insulation is fully aligned with the air barrier or drywall.

Thermal Performance

The Low Emittance High Reflective surface facing an Air Film adds R-value to the insulation system

• Ceilings: R- 4.6

• Walls: R- 1.7Reference: Surface Conductances and Resistances for Air, ASHRAE Fundamentals Handbook.

Another Solution: PLENUM AREA APPLICATION

FSK Shield™ can be installed in the Plenum Area as FACING FOR UNFACED BATTS or as a facing for Fi-Foil’s Masonry Wall insulation - AA2 Vapor Shield, to achieve a Class A rating.

A Plenum Area is often the air return for an air conditioning system. In some buildings, the area above a drop ceiling is used as the air return (source of air) for the air conditioning.
