Alpha style 3243-MA is a lamination of Alpha’s Style 4348-AMAU and Navy hullboard fabric. The 4348-AMAU is a triple layer of lamination of aluminum foil, fiberglass scrim and a special metallized polyester film. The navy hullboard meets MIL-C-20079 Type I Class 2.
APPLICATIONS
Alpha Style 3243-MA is designed as a facing material for mineral fiber and polymide foam hull and pipe insulation in below ambient applications.
ADVANTAGES
This extremely tough jacketing and facing material provides abuse resistance and vapor retardation for applications where the insulation is exposed to physical and mechanical damage.
