Data Sheet

Johns Manville AP^™ Foil25 Polyiso Continuous Insulation is a 25-psi compressive strength board that consists of a closed-cell polyisocyanurate foam core bonded on each side to a foil facer. AP Foil25 is well suited for below-grade residential applications, as well as commercial applications where higher compressive strength boards are preferred for certain exterior cladding systems. AP Foil25 is a water-resistive barrier, vapor barrier and air barrier all in one.

Advantages

Thermally efficient: Inch for inch, polyiso has one of the highest energy efficiencies
Water-resistive barrier: Meets ICC-ES AC71 acceptance criteria
Vapor barrier: Class I vapor retarder
Air barrier: Meets the Air Barrier Association of America boardstock criteria when properly installed
Noncorrosive: Does not accelerate corrosion of pipes, wiring or metal studs
